Circulation Heaters

Malaysia Famous Circulation Heaterscirculation heater

Circulation Heaters also known as “in line heaters” use steel, stainless steel, and titanium flanged immersion heaters in many applications. An electric process circulation heater is used to flow a fluid directly over the heating elements.  Lube oil and waste oil applications often use steel for circulation heaters as it is fairly inexpensive compared to stainless steel counterpart. Water circulation heaters are made with stainless steel because of its anti corrosive qualities. Both applications involve using a pump that flows the liquid through a closed pipe circuit IE. water or glycol solution) that is reheated. A major consideration for this application is viscosity. Heat that is generated by the oil heater allows the liquid to be viscous enough to pass through the circuit of pipes. Circulation heaters come in a range of watt densities that are specifically designed for the medium that is heated. The required wattage to heat the oil or water is highly correlated to the flow rate (in GPM). The oil or water enters through an inlet (the inlet closest to the flange heater) and gets heat applied to it as it flows within a vessel chamber and exits the outlet nozzle (or flange) where it circulates throughout the piping circuit. Insulation is often required for vessels in order to preserve the heat to be applied within the vessel. Efficient heat application can often reduce unnecessary costs through heat loss. Digital thermocouple probes or RTDs, can be  used with the electric immersion heater to maintain the oil or water at the preferred temperature. Many applications use liquids with low flash point and, require explosion proof housing (NEMA 7) to avoid potential mishaps.

dpstar circulation heaters are compact heating systems for fluids and gases. These heaters are ideal for applications such as purified and inert gases, supercritical fluids and liquids like de-ionized water for use in semiconductor and electronics industries as well as for general liquid and gas heating applications.

Circulation heaters, also referred to as “in-line heaters” are used for heating flowing liquids and gases. Non-pressurized or highly pressurized fluids can be heated very effectively using either direct or indirect circulation heating. A wide variety of standard designs and custom engineered power ratings, sizes, flow capacities and options are available to fulfill most any application needs.

Direct immersion circulation heaters are powerful, electric in-line circulation heaters constructed of a screw plug or flange-mounted tubular heater assembly installed into a mating tank or vessel. Inlet and outlet nozzles in the vessel permit liquid or gas flow into and out of the circulation vessel. The tubular heaters are in direct contact with the fluid being heated. Standard design circulation heaters use standard screw plug and flange immersion heaters in order to allow for easy replacement and retrofit. Custom units can be designed to suit.
