What is the HTC Process Air
Heater?
The HTC process air heater is designed to control the temperature of dry air as
it enters a material hopper. This process air heater can be set to increase, or
“raise”, the temperature of air that was dehumidified at a central dryer or from
a blower as part of hot air drying.
The HTC includes a control center, heater box with electric heating elements,
an airflow differential pressure switch, and an RTD temperature probe(s).
The differential pressure switch places the HTC in standby mode to save energy
and prevent heating element damage when air flow is not present.
