1
Value is dependent on concentration of glycol. Value shown is based on minimum glycol concentration applied.
2
Water temperatures of FreeCool systems vary depending on ambient conditions, therefore no min / max can be specified.
3
4.32 MPa for unit sizes 010 → 065. 3.00 MPa for unit sizes 092 & 130.
4
Default tolerance for standard design. 1 MPa options available.
5
Limit is based on 100% cooling performance of unit's nominal. Higher ambient temperatures can be achieved with a lower cooling capacity.
6
30 °C Limit for sizes 092 & 130.
