APPLICATION
- Duct electrical heaters are designed for heating of intake fresh air transported through the ventilating system.
- The heated air must not contain any combustible or explosive substances, chemical vapours, dust, soot etc.
- The duct heaters are the complete units and are not designed for independent operation.DESIGN
- The casing and the terminal box are made of galvanized steel and the heating elements are of stainless steel.
- The heaters are equipped with rubber seals for connection to the air ducts.- HP-E duct heaters are equipped with two overheating protection thermostats:
> basic protection with automatic restart with +50 °С operating temperature. After cooling the thermostat
closes the control circuit of the heater automatically.
> emergency protection with manual restart (operating temperature +90 °С). In case of response the
power supply to the heater is allowed after the manual emergency reset only.
> the thermostat contacts are located in the terminal box for external connection.
- Each standard size has several electric capacity options.
- The higher capacity can be attained by means of installation of the heaters in series.
- All the three phase heaters have star connection.
- The heaters are designed for operation n enclosed spaces at the ambient temperature ranging
between -30°C up to +50°C.
- Do not heat the air above +40°C.
MOUNTING
- The heater design ensures its mounting on the round ducts in any position by means of clamps.
- The air flow direction shall match the pointer on the filter.
- The duct heaters can be installed in any position except for with the electric control unit below to prevent liquid
penetration and wiring short circuit.
> The mounting shall be performed in such a way as to enable uniform air distribution along the entire
cross section.
> The air filter shall be installed at heater inlet to protect the heating elements against pollution.
> The minimum distance between the heater and other system elements is no less than two connecting
diameters.
> The duct heaters are designed for minimum air flow speed 1.5 m/s and the maximum operating outlet
temperature +40°C for heaters with heating capacity from 0.6 up to 2.4 kW and maximum
temperature +30°C for heaters with heating capacity from 3.0 up to 9.0 kW.
In case of speed control option ensure the minimum air flow through the heater.
> Power supply to the heater shall be disabled if the fan is not running.
> To ensure the correct and safe heater operation he automation system can be applied to ensure the
complex control and protection:
- automatic control of heating elements capacity and air heating temperature
- checking filter condition by means of differential pressure sensor
- power supply disabling in case of supply fan shutdown or airflow speed decrease as well as in case of the built-in overheating thermostats operation
- shutoff of ventilating system with blowing of electrical heating elements
