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 dehumidif ied at a central dryer or from a blo wer as part of hot air drying. The HTC includes a control cen[...]
