All correction factors are based on unit entering conditions of 29.4°C (85°F) DB, 18.1 °C (64.5°F) WB, 1368.6 L/S (6950 CFM), 1.72 L/S (27.3 GPM), and 7.2°C (45°F) EFT.
*Multiply capacity of device or system by factor above for % solution. **Multiply pressure drop of system by factor above for % solution.
***Glycol concentrations over 50% are not recommended.

*Airflow reduced to 4000 SCFM at this condition to maintain adequate return gas temperature. |
|
Note: Unit is not recommended for use with total loads of 10 kW or less. |
|
Note: Shaded lines represent leaving air temperatures above ASHRAE specifications of 25°C (77º F) at maximum airflow.
Note: Reduce airflow and cooling capacity specifications by 7% for cooling units run at low input voltage (380 V).
