High-performance electric heating unit TEH 400

Powerful heating without flames, smoke or condensation: With the electric heating unit TEH 400

At present, this extraordinarily robust heating unit of German high-quality manufacturing is probably the world’s most powerful mobile electric heating device on the market!

You require extremely large-volume, fully smoke-, flame- and condensate-free amounts of warm air – for instance for blasting, coating and painting work or load tests?

If so, the high-performance electric heating unit TEH 400 is our best recommendation: This hot air giant can withstand the harshest conditions whilst producing up to 9,000 cubic metres of hot air per hour at an air pressure of up to 600 Pa in continuous operation. Owing to this capacity, the high-performance heating device can transport hot air via air hose distances of up to 100 metres length.

A constant ambient temperature control for all applications is ensured by the TEH 400’s electronically controlled multi-stage switching for air volume and temperature. The ideal solution for all fields of application requiring large amounts of warm air whilst the use of indirect oil heating units is not possible.

A few practical benefits:

  • Professional quality “made in Germany” – originally produced by Trotec
  • 120 kW heating capacity
  • Air flow rate max. 9,000 m³/h at 600 Pa
  • Reliable, portable “Plug & Play” solution: Just set it up, install it, switch it on – all done!
  • Electronically controlled multi-stage switching for air volume and temperature
  • Suitable for air transport distances of 100 metres hose length
  • Stackable construction
  • Equipped as standard with shock protection frame, crane lugs, forklift slots and transport wheels with parking brakes
