NOTES:
1. Data is based on 180°F entering water and 65°F entering air temperature at sea level. See selection procedure for other conditions.
2. For optimum diffuser performance in overhead heating applications, the supply air temperature should be within 20°F of the desired
space temperature. This typically requires a higher air capacity which provides higher air motion in the space, increasing thermal com-
fort. The hot water coil should be selected with this in mind, keeping the LAT as low as possible.
The ENVIRO-TEC
®
Windows
®
based Computer Selection Program is available through your ENVIRO-TEC
®
representative for com-
plete CFR selection and hot water coil performance data.
