In-Line Circulation Heaters

In-Line circulation heaters are packaged units designed to heat a flowing medium using in line heaters. In line heating offer high efficiency since all heat is generated within the solution. Fluids or air are directed past the heating elements giving fast response and even heat distribution.

Control Panels with digital thermocouple probes or RTDs, can be used with the electric immersion heater to maintain the oil or water at the preferred temperature. With different selectable terminal enclosures, sheath and vessel materials, flanged connections, and controls, in line circulation heaters provides a wide range of applications which include: Water Heating, Heat Transfer Oil Heating, Fuel Oil Heating, Steam, Air, and Gas Heating and others. A wide selection of kilowatt ratings, materials, vessel sizes, terminal enclosures, control features and mounting methods are available for all types of heating requirements.

Other useful features found with circulation heaters are drain valves. They can be installed in any location on the vessel and allow for easy maintenance of the heater. The water or oil can be purged through the drain valve allowing for maintenance on the elements. Calcium deposits and other residue can be found on elements and should be cleaned several times a month.

GW Horizontal In-Line Circulation Heater


GW in line circulation heaters also come with the choice of horizontal or vertical mounting depending on your application. Applications involve using a pump that flows the liquid through a closed pipe circuit (IE. water or glycol solution) that is reheated. 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.

GW In-Line Circulation Heater With Skid


GW skid mounted in line circulation heater vessels are used in oil or water heating industries that require mobility. Applications involve using a pump that flows the liquid through a closed pipe circuit (IE. water or glycol solution) that is reheated. 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). Insulation is often required for vessels in order to preserve the heat to be applied within the vessel. Digital thermocouple probes or RTDs, can be used with the electric immersion heater to maintain the oil or water at the preferred temperature.
