Cabin-style heaters are used mainly in the chemical, petrochemical, and petroleum industries. The heat inside of the cabin shell is directed outward to coils in the inner walls. This provides direct heating of the process fluids passing through the coils. This type of unit is primarily used in difficult high-temperature processes (Amine and DEA re-boilers) where frequent cleaning of the combustion chamber is needed. Capacities range from 1 to 50 million Btu/hour.
