EKS – rectangular duct heaters

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. 

EKS - without internal controls

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

*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.  

Models and maximum outputs:

  Model Triac step Extra steps Voltage Max. output
  EKR 15.1 15kW 1x5A/230V 3x400V 30kW
  EKR 15.1P 15kW 4x5A/230V 3x400V 240kW

*Sensors should be ordered separately.  

Controller for three-phase electric heaters with power up to 480kW. 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.  

Models and maximum outputs:

  Model Triac step Extra steps Voltage Max. output
  EKR 15.1 30kW 1x5A/230V 3x400V 60kW
  EKR 15.1P 30kW 4x5A/230V 3x400V 480kW

*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.

EKS NV - stand-alone heater with a temperature setpoint on casing (0..30°C)

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.

Accessories

PTC – electronic protection from insufficient airflow. The heater is only allowed to work if the airflow velocity is 1,5m/s or higher.

EKS NI - stand-alone heater with external setpoint (0..30°C)

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. 

PTC – electronic protection from insufficient airflow. The heater is only allowed to work if the airflow velocity is 1,5m/s or higher.
