Circulation heaters are highly efficient heating cells designed to heat liquids and gases as they flow through a pipe body. These units are 100% energy efficient, compact, and easy to install. They offer primary heating or act as a backup/start up heating source to natural or forced circulation systems.
The core of a circulation heater is a screw plug immersion heater or a flanged immersion heater that is installed into a pipe vessel. The vessel is thermally insulated and a stainless steel or rust proof painted outside metallic jacket protects the insulating material. The vessel is connected to a system through inlet and outlet NPT threaded fittings or flange connections.
Circulation heater design concept at NPH incorporates all the rugged and durable features of a tubular heater with the flexibility of a heat exchanger.
Design specifications may require a unit to meet the boiler and pressure vessel code. NPH can supply the unit designed, built and registered to the ASME code, with the applicable code stamps.
