Pacific Automation supplies a comprehensive range of industrial immersion heaters designed to deliver reliable, efficient, and precise heating directly into liquids and process fluids. Immersion heaters convert electrical energy into heat at the point of use, making them an ideal solution for applications requiring fast response, accurate temperature control, and minimal heat loss.

Built around proven Thermon technologies, our immersion heater solutions are suitable for water, oils, chemicals, and corrosive fluids across a wide range of industrial environments, from general process heating through to hazardous and critical-duty applications.

Flanged immersion heaters are a robust and versatile solution for heating liquids in tanks, vessels, and pipelines. The heater elements are mounted to an ANSI-rated flange, allowing straightforward installation, removal, and maintenance.

Over-the-side immersion heaters provide a simple, practical option for open tanks and non-pressurised vessels, where fast installation and easy removal are priorities. These heaters are designed to hang over the tank wall and heat liquids directly, making them a strong fit for utility heating and maintenance-friendly applications.

Thermon Quantum™ TruFlow immersion heaters are engineered for high-performance process heating where efficiency, reliability, and precise thermal control are critical. TruFlow heaters utilise advanced internal baffle technology to optimise fluid flow across the heating elements, eliminating low-flow zones and reducing the risk of hot spots.

This results in superior heat transfer, lower element temperatures, and extended heater life, even in demanding industrial environments.

Thermon Quantum™ DuoFlux immersion heaters are designed for applications requiring very high power density and efficient heat transfer within a compact heater design. DuoFlux technology allows increased heat output while maintaining controlled element temperatures, making it ideal for space-constrained or high-duty process applications.

To complete the heating system, Pacific Automation supplies a full range of immersion heater accessories and control solutions, ensuring safe, efficient, and compliant operation.

Available accessories include:

• Temperature controllers and thermostats

• Level switches and over-temperature protection

• Control panels and power distribution

• Terminal enclosures for harsh and hazardous environments
