FAQ's

Q1. Is ClimaCheck available as a portable unit as well as a permanent fixed installation?

Yes, the portable PA PRO version comes in a durable ABS Case with wheels, handle and an optional accessory case and can easily be transported in the car, train or plane. The permanently installed version consists of a DIN Rail mounted ClimaCheck Module and Power Meter, which can be mounted in the ACR System Control Panel or we can provide this within an ABS weather-proof housing with clear Perspex see-through door with all the main components pre-wired following to which you simply connect the Temperature/Pressure Sensors and Current Transformers.

Q2. How quickly can I set up the Portable System to conduct an analysis of a Refrigeration Circuit?

The ClimaCheck Portable System can normally be set up and connected within 20-30 minutes, following which data recording can commence at 1, 5, 10, 30 and 60 second intervals.

Q3. In what forms can I view the data being recorded?

The results can be viewed as a Refrigeration Circuit Diagram with all the values dynamically changing. Alternatively, you can view the results line-by-line within an Excel-style dynamic form on screen or as a constantly changing graphical output showing all key parameters.

Q4. Do I need a powerful computer to use in conjunction with my ClimaCheck System?

No. A low cost elementary PC is adequate and even extensive ClimaCheck data files do not require much hard disk space. The clock speed of the computer is also relatively unimportant and so a low cost notebook PC will suffice.

Q5. Can I set up my Portable ClimaCheck System and then leave site for a few days whilst it continues to record the performance of the Refrigeration or Air Conditioning System?

Yes, ClimaCheck will record several thousand lines of data, which, at one minute intervals will last you a few days. The precise volume/time is dependant on the complexity of the Circuit that you are measuring and of course the recording interval frequency that you have set.

Q6. Is ClimaCheck easy to use?

Yes.

Q7. Is Technical Training for ClimaCheck available?

Yes. You can either come to our premises for a pre-arranged Training Session with Mike Creamer or one of his colleagues or you can attend one of our regular Training Days, which we run at approximately 3-4 month intervals. Alternatively, we can provide the training at your offices or on site, although for site-based training there will be a charge for this service.

Q8. Are the Pressure and Temperature Sensors properly calibrated and is a Certificate verifying this issued with each ClimaCheck System?

Yes.

Q9. When did the development of ClimaCheck originally start?

Klas Berglöf, the original developer commenced work on this technology approximately 1996.

Q10. Has ClimaCheck won any Awards?

Yes, ClimaCheck was voted Refrigeration Product of the Year at the ACR News Awards – February 2009. ClimaCheck was also voted Finalist at the RAC Awards under Environmental Product of the Year – Refrigeration.

Q11. How long has Mike Creamer and Business Edge been using ClimaCheck?

Mike has successfully employed ClimaCheck on many Projects since early 2007. His ClimaCheck has been used for troubleshooting, arbitration, refrigerant retrofits, capacity verification of Compressors, Heat Exchangers, Condensers and so on. ClimaCheck has been successfully applied in many instances where controls, expansion devices, refrigerant charge and head pressure control settings have been set incorrectly and following adjustments, ClimaCheck has recorded the improvements made.

Q12. Can ClimaCheck calculate the CO2 emission from a Refrigeration Plant?

Yes. This is calculated dynamically and presented so as to enable Refrigeration Engineers to optimise system performance so as to reduce energy consumption, whilst showing them the reduction in CO2 emissions as a result of their work.

Q13. Can ClimaCheck be used for Commissioning Systems?

Yes. It is the perfect tool for Commissioning as literally every parameter is recorded and displayed and the Refrigeration or Air Conditioning System can be perfectly set up and signed off, with solid documentation at the point of handover.

Q14. Is the Portable ClimaCheck System a realistic Service Tool for Service & Maintenance Engineers to use in their everyday work?

Absolutely. Given the short time taken to connect ClimaCheck to the System and the immediate display of precise System operation within just a few minutes of operation, the Service & Maintenance Engineer can make the appropriate judgements as to what adjustments might be required, determination of refrigerant charge, cooling capacity, erratic controls and so on. Following any corrections that are made, additional recordings then provide solid Service & Maintenance Reporting for the company and the end user customer.

Q15. How does the permanently installed ClimaCheck System provide communication remotely?

If a cabled site connection to the Internet can be established to the ClimaCheck Module, it is then possible to make contact with ClimaCheck from literally anywhere in the world using any type of web browser such as Internet Explorer, Safari, etc. Indeed, it is even possible to make such connection using any Internet-based phone, although those with larger screens such as the Apple iPhone or iTouch are easier to read. Alternatively, we supply a MODEM, which allows remote communication on a wireless basis and which provides all of the aforementioned facilities.

 

Q16. Can ClimaCheck contact me to let me know if my System is in trouble?

Yes. Simple parameters can be set to warn you immediately of excess or inadequate superheat/sub-cooling, which in turn can warn you of refrigerant leakage. Other issues such as unstable operation are also detected and again warnings are automatically issued in the form of Text-SMS Messages and/or Emails to nominated recipients according to a weekday / weekend schedule that you define.

Q17. It is indicated in the download literature for ClimaCheck that the price is 3,000 pounds, yet your price in the Excel sheet is 4,000 pounds?

The Excel pricelist provided in our standard email is the one that you must use for up to date pricing. Prices are subject to periodic fluctuations which may not be reflected in current literature available online. The Excel pricelist contains ordering information and payment details that are not available from any other source.

Q18. We note you have different software so need to know which is correct or sufficient for our business.

There is only ever one current version of the software and that will be issued to you in the event that you place an order. There are a number of additional templates designed to handle systems other than the conventional compressor/condenser/TEV/evaporator arrangement. These are set out in the pricelist and are self-explanatory, covering for example, systems with an economiser, oil cooler, etc.

Q19. Will the software supplied with ClimaCheck be sufficient to analyse Supermarket compressor Packs with up to 8 compressors fitted?

The standard software issued with ClimaCheck has been used many times to analyse supermarket compressor packs with multiple scroll or reciprocating compressors. This however assumes that you would be measuring the total power input to the entire group of compressors and ClimaCheck then provide you with the overall power input, total system capacity and heat rejection, isentropic efficiency of the compressor group as a whole (only of course for those that are running). If you wish to thoroughly measure the performance of such a system in order to obtain the performance of each compressor, you can proceed in one of two ways:

a) Apply the ClimaCheck power meter only to the compressor to be evaluated. This is the approach most commonly used where water chillers are concerned and where for example two or three large single compressors serve one refrigeration circuit. In such a case, it is a simple matter to move the current clamps serving the power meter from one compressor contactor to the next. Where a permanent ClimaCheck installation applies, one can fit CT's to each compressor electrical power input wiring, but this then requires a dedicated power meter for each compressor. The power meters can easily be multiplexed (up to a maximum of 8) but of course there is a cost implication to consider here. Where large compressors on a water chiller are concerned, the economies of scale make this a viable proposition. However, where small scroll compressors apply, I'm inclined to always consider a single power meter for the group. Also please note that a special template would be required to display multiple circuits simultaneously in the software (which is available to order separately).

b) Alternatively, one can connect ClimaCheck and its power meter to one compressor at a time and run the system with the other compressors idle (by switching their isolators off). Whilst this will provide you with the cooling capacity, power input, heat of rejection, isentropic efficiency and so on, this method will of course artificially boost the performance of the single compressor as it now experiences far less arduous operating conditions as a result of the relatively large heat exchangers (oversized condenser, for example).

Q20. Will the software supplied with ClimaCheck be sufficient to analyse water chillers/cooling towers?

Yes - the standard software will manage a simple system, as described above, and the portable ClimaCheck system can be dedicated to measuring one refrigeration circuit at a time, each with one or more compressors. Where water chillers are concerned, I recommend that you purchase four of the optional Binder probes to enable you to accurately measure evaporator water in/out and condenser water in/out, where applicable. ClimaCheck does not conduct any performance analysis of the cooling towers directly. However, as ClimaCheck provide you with both the cooling capacity at the evaporator and the heat of rejection at the condenser, and given that you are able to measure the water in/out temperatures for both, ClimaCheck actually calculates the water flow rates and you can display these dynamically by bringing up the appropriate columns in the Report Sheet view. Consequently, the heat of rejection being performed by the cooling towers is thus determined and you may wish to consider measuring ambient wet bulb temperature simultaneously if you are seriously in need of evaluating the cooling towers.

Q21. Are the software updates provided free?

Yes.

Q22. Can ClimaCheck provide a "snap shot" of the before and after energy savings benefits to show the client?

Yes - provided you are able to take such measurements under stable operating conditions. Where process cooling is concerned and steady-state load applies, this is easily achievable. Where air conditioning or refrigeration loads are concerned, these are normally subject to considerable variation across the day, as is the ambient dry bulb and wet bulb temperatures. Consequently, whenever I have had to conduct a comparison analysis, I have to run ClimaCheck for one or two days at a time and I then run through the data to find identical operating conditions for before and after any modifications in order to draw a comparison. Another major advantage is the ability to be able to see the evaporating and condensing temperatures in relation to entering/leaving water temperatures, and where a high differential exists, one can evaluate the performance and condition of the heat exchangers, this being very useful where visual inspection is simply not possible.

Q23. Can ClimaCheck act as a 3 phase and 1 phase power logger?

Yes - provided the power meter is connected to the ClimaCheck system and ClimaCheck is set to logging (you have 1, 5, 10, 30 and 60 second interval choices) you can then maintain a log of the kilowatt power input, the amps per phase, voltage per phase and power factor. Please note that the power meter has no integral logging capability of its own.

Q24. As we are based in Asia where could we get the analyser fixed if it failed during warranty and out of warranty period?

We have no repair facility in Asia at this time but it is a simple matter to send the analyser back to ClimaCheck Sweden for repair, this having the advantage of them being able to re-commission it and recalibrated if necessary. Our long-term experiences have shown that the incidence of failure is exceptionally low. For example, the PA Pro logger (the ClimaCheck brain) has never experienced a failure. We have had three power meters fail but this has proved to have been due to incorrect connection by the user. I recall perhaps only one temperature sensor failing in the last two years. We have never had a pressure transducer failure.       

Q25. As we are based in Asia travelling to the UK for training will literally add thousands of pounds to the cost of purchasing the analyser. Is there any other location or method for training as the cost of air travel to the UK, accomodation etc, and cost of the analyser itself make it a very expensive purchase?

I appreciate your point here. Where training is concerned, I would firstly like to emphasise that in order to fully appreciate and utilise the enormously wide range of facilities within the hardware and software, training is essential. However, the supporting technical manual which can be read directly from within the ClimaCheck software on your PC, is excellent. Consequently, it is possible to set ClimaCheck up and make good use of it without a training course, provide one applies oneself to reading the manual. We are currently running one-day training courses for our clients here at Business Edge Limited and these are normally attended by 25-35 people. Our next training session is Monday 21st February and you are welcome to attend this FOC.

ClimaCheck Sweden in conjunction with Business Edge Limited will also be running its international training courses here and they will be of two days duration in order to cover the entire training requirement to a very in-depth and hands-on level. We have three operational refrigeration systems here and three ClimaCheck systems thus enabling the attendees to work directly on the equipment. ClimaCheck Sweden are making a nominal charge of €400 per candidate.

Q26. What enhancements does the PA Pro II have over previous models?

 

The major difference between the PA PRO and the new PA PRO II released Q1 January 2011 is the Power Meter. What are the changes?
 
i)                    The voltage monitoring side of the Power Meter has been electrically isolated from the power supply to the Power Meter. This has been achieved by providing a 24Vdc supply via the main PA PRO’s RS232 cable or by utilising a Power Adapter
 
ii)                   By separating the power supply from the voltage monitoring side, we’ve eliminated the possibility of the user damaging the meter by misconnecting the neutral to a live source and this also avoids the risk of tripping any site residual current devices (RCD’s) otherwise caused by connecting neutral to earth
 
iii)                 Further enhancements have been made to accommodate UL certification, rendering it acceptable to the US market
 
iv)                 New harmonised phase colours are being used with cable identification markings that are also compatible with US/Canadian Standards

Q27. Is the Fri3Oil Machine based on new technology?

No, the original development started in Spain 20 years ago and has been gradually perfected over the years, culminating in the current machine, which is sold exclusively by Business Edge Limited throughout the UK.

Q28. What does the Fri3Oil Machine do?

The Fri3Oil Machine conducts the following:

  • Refrigerant recovery at a exceptionally fast rate.
  • Recycling (cleansing) of the refrigerant removed.
  • Use of the clean refrigerant for repeated flushing operations of the refrigeration system.

 

Q29. What exactly is the Fri3Oil capable of removing from a System during the flushing process?

Oil, water vapour, liquid water, particulates and acids.

Q30. Can the Fri3Oil Machine clean the insides of vessels such as Suction Accumulators, Liquid Receivers, Compressors and so on?

Absolutely. The liquid flushing process can literally remove all of the oil from the crank-case of a compressor and will indeed even remove liquid water from the crank-case!

Q31. Has Fri3Oil been successfully applied here in the UK?

Yes, Fri3Oil has been used to flush out large Water Chillers at the Science Museum, Transport Refrigeration Systems and many installations involving extensive pipe runs. Where a replacement Water Chiller within the basement and a roof mounted air-cooled condenser arrangement exists, it has been necessary to remove all traces of the original mineral oil, particulates and so on in order to allow the replacement Water Chiller to run on an alternative refrigerant and a new synthetic oil. Fri3Oil has therefore eliminated the need to remove refrigeration pipe work, which would otherwise be very expensive in terms of materials and labour, especially where long pipe runs are concerned in large buildings or buildings with many floors.

Q32. Can the Fri3Oil System flush extensive line runs comprising horizontal and vertical sections with numerous bends, etc?

Yes.

Q33. Is the Fri3Oil Machine portable?

The machine is fairly heavy (circa 80kg), but is very robustly made with a stainless steel casing and good castors for moving it around. In addition, we offer a special hydraulic lifting platform, also fitted with wheels, which makes the ideal work station for Fri3Oil. Moreover, during its operation, Fri3Oil should be elevated from floor level and the hydraulic table also serves this purpose.

Q34. Can Fri3Oil operate on any refrigerant?

Yes. R22 is in fact the best refrigerant in terms of its scouring cleansing capability. However, the principle that Fri3Oil employs works with all fluorinated gases. Fri3Oil cannot be used with Ammonia, CO2 or Propane refrigerants.

Q35. Is the Fri3Oil Machine difficult to use?

No, provided you have been fully trained in the correct use of the equipment. A Training DVD is also available and Business Edge runs regular training courses for this purpose.

Q36. Can I hire a Business Edge Refrigeration Engineer and the Fri3Oil Machine to conduct flushing operations at my site?

Yes, we can arrange hire of our Engineer, complete with refrigerant, cylinders and our own Fri3Oil Machine to assist you on site.

Q37. What level of cleanliness can the Fri3Oil Machine achieve when it is recycling my refrigerant?

Contaminants and impurities to less than 200ppm are achievable.

Q38. Can I use a low cost refrigerant with my Fri3Oil System to flush a refrigeration system and then revert to the final refrigerant intended for the system, this perhaps being much more expensive?

Yes. We commonly use a stock of a given refrigerant for that very purpose, which is contained in our stock of cylinders, these being transported to site with the Fri3Oil Machine as part of the overall flushing operation.
