Rectangular Duct Heaters

Copra AS have distribution in Norway for all Ventmatika products. Rectangular duct heaters are used in ventilation systems as heaters for comfort, or preheaters, to protect ventilation unit for 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. Various control methods and accessories possible, listed below. Non-standard solutions possible. Contact us with your requirements to learn more, or check the product sheet.

  • 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.
  • Power supply
    • 3 phase 400v/440v 50/60Hz

 

EKS – without internal controls

Without internal controls, the heater is controlled by external controller.

 

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.

 

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.

 

EKS NIS – controlled via external 0..10VDC signal

Controlled via external 0..10VDC signal.

EKS NV PTC/PS – stand-alone heater with setpoint on casing (-10..+50°C) and additional protection from insufficient airflow

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.

 

EKS ESKM – controlled via external 6..24VDC PWM signal

Heater controlled via external 6..24V PWM signal.

Equipped with an extra safety thermostat set at 70°C to protect internal components.

 

EKS MB – controlled via ModBus protocol

Heater is controlled via ModBus RTU485 protocol.
