APPLICATIONS
Ducted electric heaters are designed to heat the supply air in a circular ventilation system. The heaters are used in heating, ventilation and air-conditioning systems for various spaces.
DESIGN
The shell and terminal blocks are made of galvanized steel and the heating elements are made of stainless steel. The heaters are equipped with rubber seals for connection to air ducts.
NK duct heaters are equipped with two thermostats with overheating protection:
Basic protection with automatic restart at an operating temperature of +50 °C. After cooling down, the thermostat automatically closes the heater control circuit.
Emergency protection with manual restart (operating temperature +90°). In the event of a response, the power supply to the heater is only enabled after a manual emergency restart.
The thermostat contacts are located in the terminal block for external connection.
Each standard size has several electrical output options. Higher output can be achieved by installing heaters in series. All three-phase heaters have a star connection.
ASSEMBLY
The design of the heater ensures its mounting on the circular pipe in any position by means of clamps. The direction of air flow must correspond to the indicator on the filter. Duct heaters may be installed in any position except with the electrical control unit underneath to prevent liquid ingress and shorting of the wiring.
The installation must be so arranged as to permit uniform distribution of air over the entire cross-section.
An air filter shall be installed at the inlet to the heater to protect the heating elements from contamination.
The minimum distance between the heater and the other elements of the system shall not be less than two connecting diameters.
Duct heaters shall be designed for a minimum air velocity of 1,5 m/s and a maximum outlet operating temperature of 40°. If speed control is possible, ensure minimum air flow through the heater.
Heater power must be turned off when the fan is not in operation.
