Note:
1. Capacities expressed as MBh per initial temperature difference (ITD) between the entering air temperature to
the hot water coil and the entering water temperature. Ethylene glycol or other capacities can be determined
from the Trane heating coil computer program. Capacity and pressure drop of ethylene glycol varies greatly
with temperature and concentration.
