Description
Description
Rectangular Electric Heater with Control
The EKS rectangular electric duct heater is designed to heat clean supply air in ventilation systems where stable temperature control matters. It is commonly specified as a supply air heater plus a preheater, helping you maintain target air temperatures across commercial and industrial ductwork.
Why this heater is specified
- Built for ducted ventilation: designed for clean air heating plus preheating duties
- Robust construction: Aluzinc coated steel casing with stainless steel heating element tube (AISI 304)
- Control options by model: choose integrated control or external control inputs to suit your BMS or site requirement
- Safety focused as standard: multiple overheating protection thermostats
- Installation flexibility: can be installed in most orientations provided the electrical connection box is not facing downward
Performance and operating limits
- Minimum duct air velocity: 1.5 m/s
- Maximum outlet air temperature: 50°C
- Protection class: IP44, except EKS type NV which is IP30
- Application limits: not suitable for explosive atmospheres or chemically aggressive environments
Control types explained
EKS heaters are available with different control approaches depending on model. This lets you match the heater to simple on site control, remote setpoint control or external signal control.
- EKS: without temperature control, heater power is not regulated
- NV: integrated control with setpoint set by potentiometer on the heater lid
- NI: integrated control with setpoint set by external potentiometer
- NIS: integrated control with heater power controlled by external 0 to 10 VDC signal
- ESKM: integrated control with heater switched by external PWM signal (ON 6 to 24 VDC, OFF)
Overheating protection
To support safe operation in ducted systems, the heater includes overheating protection thermostats. One thermostat resets automatically, plus a second thermostat uses manual reset for added protection if abnormal conditions occur.
Installation notes that matter on site
- Orientation: install in any position except with the electrical connection box facing downward
- Electrical: connection must be completed by a competent electrician and the heater must be earthed
- Protection grille: where accidental contact with heating elements is possible, a protective grille must be installed
- Temperature sensor positioning: to support accurate control, the minimum distance between heater and temperature sensor should be at least the same as the diagonal length of the heater
How to specify the correct model
Selection is normally made by confirming duct size first, then choosing power rating, supply option and control type. The model code structure identifies the heater type, control type, width, height, length, power, input voltage plus optional accessories.
