Horst tube furnaces are made of standardized components according to customer's requirements.

Each customer gets an appliance with technical features, well-suited to the individual needs.

  • As standard desktop model with detachable stand and protective barrier (pic. 1 and pic. 3).
  • As reactor heating, integrated in a production or test set-up. Picture 2 shows a variant on a running rail with counterweight for an easy position-control of the furnace.
  • As three-part tube furnace on a sliding rail
  • As a heat source in portable calibrating devices
  • As a built-in type for 19" casings
  • As a stationary model for use in combination with eight inserted furnaces, water-cooled to minimize the impact of the heat radiation impact on the operating staff (pic. 4).

Short heating-up times and homogenous heat distribution are special features of all tube furnaces.

This is achieved by using electrically insulated heating conductors, which allow a narrow winding round the tube. The total power is distributed on a relatively long heating conductor, which keeps the surface load of the heating conductor low.

Each tube furnace can be used in vertical or horizontal position and has a built-in thermocouple.

Tube furnaces must be used in combination with a temperature regulator. You can either use an available control device or choose a matching regulator from our product range, like the HT 30 or the HT MC1 regulator.
