HOT WATER COIL DATA • CFR

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 comfort. The hot
water coil should be selected with this in mind, keeping the LAT as low as possible.
