These heater are also suitable to provide, coupled with an appropriate shell, explosion proof heat exchangers. They are designed by our technical department on the basis of the customer provided functional requirements and of the requirements imposed by the ATEX specifications.
The design takes into account the physical, chemical and thermodynamic characteristics of the fluid to be heated, as well as the features of the site where the heater will operate. In fact, a good knowledge of the plant and of the role that the heater will play within the plant is required to define adequate safety margins and to choose suitable safety devices. In all cases a verification calculation is performed.
