Plating Solution Immersion Heater

Bobbin Heater

Bobbin heater is constructed using several refractory ceramic blocks assembled together to the required length. The Nichrome wire heating element is inserted into the ceramic blocks, with a terminal block at one end.

This bobbin assembly is then inserted into a pre-assembled special protection tube (Stainless Steel, Titanium etc), when used in liquid immersion and gas application.  However, bobbin heaters can also be used in direct air-heating application without the protection tube.
