Air heater EMS

ductcustom

Possible to control the heater in various ways: autonomous heater with setpoint on casign or external TR5K controller to control output temperature controlled via external controllers via: 0..10VDC | 6..24V PWM | ModBus RTU485 PTC – electronic protection from insufficient airflow. The heater is only allowed to work if the airflow velocity is 1,5m/s or higher. PS – mechanical protection against loss or insufficient airflow with differential pressure switch. The heater if not allowed to heat unless a minimum airflow of 1,5m/s is reached. By ordering the PS, an internal contactor for power supply is added to the heater as well. External wired remote setpoint for NI type heaters. The heater is working based on supply air temperature sensor. External wired remote setpoint for NI type heaters with internal temperature sensor. When connected, the heater ir working acording to the internal sensor, and the supply air temperature sensor limits supply air temperature – +15°C…+40°C. Upon request internal contactor for power supply can be added in the heater. Internal NO and NC alarm contacts added to the heater.
