short description

Electric air heater, three-phase AC, channel dimensions 600 mm x 350 mm

Product description

  • Electrical air heater for ventilation systems.
  • Flanges on both sides for installation in square ventilation channels.
  • With non-glowing stainless steel tubular radiators.
  • Heater power rating linearly adjustable.
  • Operate with DTL 24 P temperature control system (see accessories).
  • Recommended accessories: FL channel sensor or FR room sensor, LW 9 air flow monitor, TFP ... air filter, US 16 T contactor, DTL 2 P-L (at 16.5 kW to 30 kW).

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 tubular radiators are dirty. Install TFP air filter.
  • With 2 temperature limiters switching independently of each other.
  • Minimum distance to inflammable material: 300 mm (if distance is less, install appropriate insulation).
