Screw Plug heaters from WATTCO™ consist of hairpin tubular elements that are brazed or welded into a machined pipe thread fitting, (normally an NPT fitting for North American standards) which are then screwed directly through a threaded coupling in the tank wall or vessel, or installed in pipe. Screw plug heaters are an easy way to heat up solutions in smaller containers that also require controls. Mechanical thermostats or Digital controllers can be used with these immersion heaters to help reach target temperatures with great accuracy meeting your project objectives. Additional thermowells can be installed for high limit temperature probes to help protect your liquid and processes.



Screw Plug heaters from WATTCO™ are used for heating gases and liquids in tanks or vessels. These elements are designed to be immersed in liquid so that heat transfer will occur at a rapid rate, enabling quick heat up times. Typical uses include the food and beverage industry, laboratory clinics, applications involving hydraulic oils and lubricants as well as more sophisticated uses such as heating up flammable liquids or gases which require explosion proof housing.
