Electric process heaters are used in many industrial process applications to heat liquids and gases. dpstar offers custom design Circulation electric heaters engineered with versatility to meet most application and site requirements. Maltec-H electric process heaters are manufactured to the highest quality standards and including UL and CE certified.
Circulation Heaters 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 inexpensive compared to stainless steel.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 that is reheated. 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. Thermocouple probes or RTDs, can be used with the heater to maintain the preferred temperature.
