The electric heating thermal oil boiler, also known as an electric oil heater, is an energy-efficient heating unit that uses electricity as the heat source and thermal oil as the circulating medium. A hot oil pump provides forced circulation to deliver heat to downstream equipment. It features a compact structure, small footprint, light weight, easy installation and operation, fast heat-up, and zero environmental emissions.
Working Principle & Features:
The WDR series electric heating thermal oil boiler is an energy-efficient heating unit developed based on advanced domestic and international technology. It uses electricity as the heat source and thermal oil as the circulating medium, with a hot oil pump providing forced circulation to deliver heat to downstream equipment. It features a compact structure, small footprint, light weight, easy installation and operation, fast heat-up, and zero emissions. Computerized automatic temperature control achieves high working temperatures at low operating pressure.
Technical Performance & Applications:
The boiler operates stably at low pressure (≤0.4 MPa) with fully automatic computer control and thermal efficiency above 90%. Widely used in petrochemicals, oil & fats, building materials, textiles & dyeing, food processing, plastics, rubber, pharmaceuticals, and other industries, it is an ideal new-generation electric heating solution.
