- 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.
