Notes

Nominal cooling capacity is calculated with 7’C chilled-water supply and 35’C inlet cooling air temperature at system flow rate and pressure
Recommended temperature range of chilled fluid: 3’C and 25’C. Use of glycol recommended for set points under 6’C.
Temperature difference between inlet and outlet chilled fluid between 4’C and 7’C. Contact us for temperature splits outside of this range
All figures are at the rating point of 7c supply in 35c ambient.
We recommend the use of R134a when ambient temperatures are expected to reach 42’C+
