Used in ventilation systems as heaters for comfort, or preheaters, to protect the ventilation unit from frost.
Frame is made from AluZinc coated steel, which is highly resistant to corrosion.
Heating elements are made from stainless steel AISI304.
All heaters are equipped with protection thermostats – automatic 50°C and manual – 100°C which prevent overheating.
Standard sizes: 400×200 | 500×200 | 500×250 | 500×300 | 600×350 | 700×400 | 800×500 | 1000×500
Other sizes available upon request.
Possible power output- 0.3kW – 200kW, depending on chosen control type.
Various control methods and accessories listed below.
Non-standard solutions possible.
Without internal controls, the heater is controlled by external controller.
Heater controller for single and two-phase electric heaters. Controls by supply* or room temperature. Has an internal temperature sensor in casing, supply air temperature sensor is required for operation in both modes.
Controlled power:
1x230V – 3.2kW
2x400V – 6.4kW
Maximum current: 16A
*Sensor should be ordered separately.
Controller for three-phase electric heaters with power up to 240kW. Controls by supply or extract air temperature sensors* or an external 0..10VDC control signal.
Extra steps activated by sequential or binary mode, depending on heater power.

*Sensors should be ordered separately.
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.
Contact our sales department for more information
Upon request internal contactor for power supply can be added in the heater.
Contact our sales department for more information.
Stand-alone heater with internal controls and temperature setpoint on casing. Measures the temperature and works autonomously when heating is needed.
Supply air temperature sensor TJ-K10K is included in the box.
PTC – electronic protection from insufficient airflow. The heater is only allowed to work if the airflow velocity is 1,5m/s or higher.
