EKS – rectangular duct heaters
Used in ventilation systems as heaters or preheaters, protecting the ventilation unit from freezing.
Frame is made using Aluzinc coated steel, which is highly resistant to corrosion.
Heating elements are made from stainless steel AISI304.
All heaters are manufactured with thermal protection – automatic (50°C) and manual (100°C).
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.
Accessories
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
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.

Stand-alone heater with internal controls. Setpoint controlled via external TR5K or TR5KNTC10 controller. Measures the temperature and works autonomously when heating is needed.
Supply air temperature sensor TJ-K10K is included in the box.
TR5K or TR5KNTC10 should be ordered separately.
Accessories
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.

Stand-alone heater controlling air temperature from -10°C to +50°C. Protection from loss of airflow by airflow sensor PTC and diffeal pressure switch PS.
With extra protections and a broad choice of setpoint temperature, the heater is a great choice for preheating the air before a heat exchanger to prevent frost.
Supply air temperature sensor TJ-K10K is included in the box.
Accessories
Heater can have different setpoint values. Maximum temperature – +50°C.
For different setpoint values contact our sales department.
Heater controlled via external 6..24V PWM signal.
Equipped with an extra safety thermostat set at 70°C to protect internal components.
