short description

Electrical air heater, DN 200, 230 VAC / 50 Hz, 2.1 KW

Product description

  • Electrical air heater for ventilation systems.
  • With non-glowing stainless steel tubular radiators.
  • Operate with ETL/DTL temperature controller (see accessories).
  • Increased danger of fire if tubular radiators are dirty. Install TFE air filter as a prevention.
  • Recommended accessories: FL channel sensor or FR room sensor, LW 9 air flow monitor, US 16 T contactor and TFE... air filter .

Installation instructions

  • Mount the water-air heater on the fan's pressure side in order to prevent fan motor overheating. An arrow marked on the housing shows the default air direction through the electrical air heater.
  • Mount a 1 m to 1.5 m long air duct fitting between fan and electrical air heater to ensure optimum inflow to the electrical air heater.
  • Inflow speed can be controlled using an LW 9 air flow monitor.
  • If the inflow speed falls below 1.5 m/s, the electrical air heater must be switched off.

Safety instructions

  • Increased danger of fire if the tubular radiators are dirty. Install TFE air filter as a prevention.
  • Design in accordance with VDE, Device and Product Security Laws and the corresponding EU Directives.
  • With 2 temperature limiters switching independently of each other.
  • Minimum distance to inflammable material: 150 mm (if distance is less, install appropriate insulation).
