Frequently Asked Questions
- How do I work out the cooling capacity that I need?
1. For new equipment the manufacturer of the equipment should be able to advise on the cooling requirement and flow rates that their equipment needs.
2. For equipment currently in use, cooled by mains water, it is possible to calculate the cooling rate using the following calculation.
Cooling (kW) = Flow rate (litre/min) x dT (°C) / 14.4
Where dT = The rise in temperature between incoming and outgoing water.
3. If all else fails add up the total power consumption of the application (in kWatts) and estimate the efficiency of the process, ie how much energy (heat) needs to be taken away by the chiller.
- Where can I get an instruction Manual?
All current manuals are available from the Support (Downloads) section of this web site.
- Which Heat Transfer Fluid should I use in my Chiller?
All ATC Chillers are suitable for use with sterile deionised water or Propylene Glycol solutions. ATC Recommend the use of Hexid A4. Other antifreeze or inhibitors are not recommended as these may corrode your application and damage the K series chiller seals. Please check with your application manufacturer for material compatibility data.
Other Heat Transfer fluids can be specified when ordering your chiller (for example oils or HFE fluids)
- What is the refrigerant used in the chiller, and how much is used?
ATC only uses CFC-free gases. The weight and type of refrigerant gas is printed on the rating label.
- Where can I find my Serial Number?
The Serial Number is printed on a small label SN: nnnnnn located near the power cord. (n is a number)
- Do we need an engineer to install an ATC Chiller?
- All ATC Chillers are supplied ready for use, and can be installed with minimum effort.
