Overview of standard Double Glass tube Air Blow Heater DGH Series

Feature

◎  This heater eliminated output of contamination to the limit.
◎  Because the heating element and the sensor do not touch gas, it is applicable also to heating of vapor or low-concentration corrosive gas.
  The gas flow is heated indirectly in the gap of the outer glass tube and the inner glass tube.
△ The limit of this heater is an operating condition of heat-resisting rubber (Viton, Silicon).
We are not recommend for heating of fluids containing residual material within the heater.

◆ Output in a short time 500℃ hot air.
◆ Builtin a thermocouple in a hot-air output unit, can easily control temperature.
◆ Directly heated nitrogen can be used in the experiment of anaerobic microorganisms.
◆ Safe, Clean and just blow with electric heating and gas supply, fire flame will not come out.
◆ The DGH can be manufactured in a range of 100w – 12kw.
◆ Outside diameter 13-140mm, DGH is compact.
