Heating Coils
One or two row hot water and steam heating
and preheating coils can be factory installed.
All valve controls for heating operation are
field supplied and field installed. Hot water
and steam coil connections are spun copper
tube.
Water coils must not be subjected to entering
air temperatures below 38°F to prevent coil
freeze-up. If air temperature across the coil is
going to be below this value, use a glycol
solution to match the coldest air expected.
