About Industrial Immersion Heaters
Caldor Heat designs and manufactures a wide range of electric industrial immersion heaters engineered to deliver efficient and reliable heating for diverse industrial fluids. From clean and process water to corrosive chemical solutions and highly viscous oils, Caldor Heat immersion heaters are designed to heat virtually any liquid used in industrial processes.
Our immersion heaters are suitable for highly specialized industrial applications, including high-pressure systems and hazardous (ATEX) environments, where durability, safety, and precise temperature control are essential.
Because immersion heating applies heat directly within the liquid or process medium, electric immersion heaters can achieve near-100% thermal efficiency. This makes them an ideal solution for industrial applications such as tank heating, process vessels, and fluid circulation systems, where consistent and efficient heat transfer is required.
Caldor Heat offers multiple mounting configurations to meet specific installation and process requirements, including:
Threaded screw plug immersion heaters
Flanged immersion heaters
Welded immersion heater assemblies
Over-the-side immersion heaters for open tanks
In addition, our immersion heaters can be supplied with a wide range of temperature control and safety options, allowing accurate regulation of process temperatures and enhanced operational reliability.
Caldor Heat maintains stock of selected standard immersion heater designs for fast delivery, including screw plug and flanged models. Alongside standard products, we specialize in custom-engineered immersion heater solutions, developed in close collaboration with our customers to meet unique technical and process challenges across a wide range of industries.

About Movable Immersion Heaters
Caldor Heat movable immersion heaters are purpose-designed industrial electric heaters for efficient heating of liquids in open tanks, basins, baths, and vessels where the liquid level may vary or where easy installation and removal are required. These heaters deliver rapid, uniform heat transfer directly into the fluid, making them ideal for process heating, degreasing, surface treatment baths, and other variable-level fluid applications.
Movable immersion heaters consist of one or more robust heating elements enclosed within a protective sheath and mounted within a frame or bracket that allows simple insertion and removal. Because they do not require permanent installation or tank modification, they provide exceptional flexibility for use across multiple tanks or changing process conditions.
These heaters are engineered for industrial performance:
They operate with direct immersion in the fluid, ensuring efficient heat transfer with minimal energy loss.
Construction uses corrosion-resistant materials such as stainless steel or specially coated sheaths, suitable for a wide range of liquids and temperatures.
The units are designed for easy maintenance and serviceability, allowing element replacement or cleaning without draining the tank.
Controls such as adjustable thermostats, thermocouples, or Pt100 sensors can be integrated to enable precise temperature regulation and improved process control.
Movable immersion heaters are used across many industries where heating efficiency and operational flexibility are paramount. Typical applications include:
Degreasing baths and surface treatment tanks, where liquids must be heated to specific temperatures.
Open fluid reservoirs with varying liquid levels.
Temporary or multi-tank operations where the ability to transfer the heater between vessels increases process efficiency.
Caldor Heat movable immersion heaters deliver reliable performance, straightforward installation, and adaptable solutions for industrial liquid heating needs. Contact Caldor Heat to discuss your process requirements and available configurations.
About In-Line Heaters
Caldor Heat in-line heaters are industrial electric heating systems engineered to deliver efficient and controlled thermal energy directly within flowing fluids and gases as part of your process line or circulation system. These heaters are suitable for applications where liquids or gases require temperature elevation as they pass through a pipeline, vessel or circulation circuit, providing uniform heat transfer without the need for large stationary tanks.
Designed for continuous flow applications, Caldor Heat in-line heaters can be integrated into process loops, circulation systems, heat recirculation units, and industrial flow-through installations where stable temperature control and rapid thermal response are required. Typical process fluids include clean and process water, industrial oils, chemical solutions, mild corrosive media, and gases used in manufacturing environments.
Key features of Caldor Heat in-line heaters include:
Direct heating of flowing media: Heating elements are configured so that fluid passes over or around the elements for efficient energy transfer.
Robust construction: Heater assemblies are constructed with high-quality materials such as stainless steel or alloy sheaths suitable for elevated temperatures, corrosive conditions, and continuous operation.
Modular design: In-line heaters can be engineered with flanged, threaded, or custom connectors, allowing seamless integration into existing piping and process equipment.
Custom power and control options: Units can be supplied with precise temperature controls, such as thermostats, thermocouples, or advanced electronic control systems for accurate process regulation.
Caldor Heat in-line heaters are widely used in industrial segments where precise flow-through heating is critical, including chemical processing, water and wastewater treatment, oil and lubrication systems, food and beverage processing, and HVAC applications. These solutions optimize heat transfer efficiency while minimizing energy losses and enhancing process throughput.
For specific process requirements, Caldor Heat also offers custom-engineered in-line heating assemblies, designed in close collaboration with customers to meet demanding industrial specifications. Contact Caldor Heat to discuss tailored in-line heating solutions for your process application.
