What Is a Rectangular Flange Heater?
A rectangular flange immersion heater is a heavy-duty electric heating device designed for high-capacity industrial applications requiring robust construction and reliable performance under demanding conditions. Unlike standard circular flanged heaters, rectangular flange heaters feature a rectangular mounting plate that distributes mounting forces over a larger surface area, providing superior stability and reduced stress on tank walls and vessel openings. This design is particularly advantageous for large-scale installations, high-wattage applications, and situations where the heater must withstand significant mechanical loads or thermal cycling.
The large diameter .475" tubular elements provide enhanced heat transfer capacity and mechanical strength compared to standard diameter elements. The enhanced electrical insulation delivers superior dielectric strength, making these heaters suitable for high-voltage applications up to 600 volts while maintaining safe operation. Element spacers made from 304 stainless steel maintain precise spacing between elements, preventing hot spot formation and ensuring uniform heat distribution across the heated medium. The minimum 3/16" plate flange construction provides exceptional durability and resistance to warping or deformation under thermal stress.
INDEECO rectangular flange heaters leverage decades of industrial heating expertise to deliver reliable solutions for the most demanding applications. With moisture-resistant epoxy seals available for temperatures up to 250°F, CSA certification for Canadian safety compliance, and options for alternate flange designs and companion flanges, these heaters provide versatile solutions for custom installations. ZIRCO's expertise in Western Canada's industrial sectors ensures you receive the right rectangular flange heater configuration for your specific high-voltage, high-wattage, or mechanically demanding application requirements.
