Application:
- evaporation of small to medium-sized quantities of gas at moderate to low pressures (types SR, NDA, HDA),
- post-heating after atmospheric evaporators (types NDA, HDA)
- evaporation / preheating where connection to hot water or fuel supplies is not possible
Design features:
- compact design
- minimum erosion, as there is no direct contact between the medium and the heating elements
- heating element easily replaceable, thus upgrading to higher heating power possible in most cases
- standard design with dual-step control
- exact temperature control via thyristor controller
- space-saving horizontal or vertical design
