EHT – High temperature industrial ovens

High temperature industrial ovens for industrial applications up to 500ºC, 600ºC and 800ºC

Laboratory-ovens-Hobersal

High temperature industrial ovens for continuous work with temperatures up to 500ºC, 600ºC and 800ºC, with forced air circulation, its sturdy design is designed for industrial work and with heavy loads thus being the most resistant of the market.

High temperature EHT ovens are ovens designed to operate at temperatures higher than those of a conventional oven. These ovens are typically used in industrial or laboratory environments where high temperatures are required for various applications such as heat treatment, curing, ageing, etc.
