In the field of industrial heating, electric heating equipment is widely used in petroleum, chemical, power, machinery and other industries due to its strong controllability and high thermal efficiency. Recently, the company has systematically reviewed its existing product line, covering multiple categories such as tubular electric heaters, sheathed heaters, explosion-proof electric heaters and supporting temperature control equipment, to meet heating needs under different working conditions.
Tubular electric heaters are a common type of product, among which the SRY series includes models such as SRY2 and SRY4, mostly used in immersion oil heating scenarios. This type of heater converts electrical energy into thermal energy by placing a resistance wire inside a metal tube and filling the gap with insulating and thermally conductive material. Sheathed electric heaters adopt a three-layer coaxial structure of core wire, insulation and sheath, a design that helps improve insulation performance and mechanical protection. The most common model system for sheathed heaters is SRY, and users can select models according to actual installation dimensions and power requirements.
For flammable and explosive environments, the company provides explosion-proof electric heaters and temperature control equipment, as well as special explosion-proof heating equipment such as HFP cracking furnaces. These devices focus on explosion isolation and sealing in their structural design, and are suitable for locations where explosive gas mixtures exist. In addition, cast aluminum and cast copper ring heaters can cover a working temperature range of 200–500°C, featuring relatively fast heat conduction and high mechanical strength, and are often used for heating plastic machinery, molds and other equipment.
In the field of bolt heating, the company produces bolt electric heating rods. This product needs to be used with a DC adjustable control cabinet to adjust the heating process. Bolt heating rods are mainly used for bolt disassembly and assembly operations in steam turbines and large machinery, expanding the bolts through heating to facilitate tightening or removal.
The company states that the above products are designed and produced in accordance with relevant standards, and specific selection needs to be comprehensively determined based on factors such as working conditions, temperature requirements and installation methods. In the future, the company will continue to improve its product system and provide more suitable solutions for industrial heating.
