Specification
The heating elements of the RFA series are characterized by more compact dimensions and are manufactured with nominally lower outputs than flanged heaters. The criteria for selection and evaluation of operating conditions are in any case the same as for flanged heaters, which guarantees that these products can be safely used in designated areas for direct or indirect heating of highly flammable substances (solvents) or highly explosive substances (LPG).
Depending on the requirements for use, threaded connections can be made of brass or stainless steel.In the menu, it is possible to choose heaters made of seamless stainless steel pipes: AISI316Ti, AISI 316L or material: Incoloy 800.The housing of the electrical terminal box is for easy installation of cabling and safety elements, or temperature sensors. It is made of cast aluminum divided into two half-shells
