The screw-in type heating elements are suitable for direct calefaction of various liquids.

The heating elements are manufactured as components ready to be installed with or without thermostats and temperature limiters, respectively:

• hot water boiler
• purifying baths
• oil preheaters
• flow heaters
• air heaters
• heat regenerators
• degreasing baths

The screw-in type heating elements are fundamentally fabricated with three tubular heating elements, being soldered in a threaded brass or stainless steel joint.

The material of the tubular casing consists alternatively of:

• special steel 1.4541
• special steel 1.4571
• special steel 1.4404
• special steel 1.4828
• special steel 1.4876 (Incoloy 800)
• special steel 2.4858 (Incoloy 825)

The screw-in type heating elements can be varied by:

• other lengths
• other non-heated areas
• other capacities
• other voltages
• other materials
• other threaded joints (S.P. threads 2", 1 1/4", 1 1/2")
• other protective systems up to IP 65
