The company has always maintained high standards of meeting the industry’s stringent demands for increased safety, quality and performance. In addition, our engineering team consistently strives to design products to better combine our customers’ needs with improved material technologies.

Heateflex offers customization for our wide range of high-purity equipment for heating fluids and gases. Many of which includes chemical heaters, deionized water heaters, gas heaters, steam heaters, and heat exchangers. These applications are able to control temperatures with extreme precision and efficiency. Further equipped with our microprocessor-based temperature controllers, the heaters can be built to adapt to the specific needs of customer applications.

The company maintains a strong patent portfolio, providing a foundation of innovation and protection for our worldwide customer base. Our award-winning engineering team continuously develops next-generation tools and applications to serve the changing needs of the industry and our customers.

Heateflex’s manufacturing facility is based in Arcadia, CA where the main focuses are fluoropolymer construction and assembly.

In July 2019, Heateflex was acquired by White Knight Fluid Handling Inc., a subsidiary of Graco Inc. (NYSE: GGG). White Knight Fluid Handling Inc. manufactures fluid handling equipment used to deliver, circulate, dispense, and reclaim high-purity fluids. Some of the processes include corrosive alkaline or acidic chemical solutions, and toxic liquids such as fuels, glues, paints, resins, inks, and wastewater. The addition of Heateflex to White Knight is part of an overall Graco strategy to deliver expanded products, technology and services to a growing list of customers int he worldwide semiconductor and solar markets.

Heating Products for Ultra-Pure Heating

Heateflex Ultra-Pure Heating Products are 100% PFA jacketed and are as rugged as they are acid resistant.

Our engineers have perfected the techniques for manufacturing Heateflex® heating products from PFA. Heateflex® heaters combines PFA technology, small mass, and a large surface area to provide longer life at elevated temperatures. Because the coils are extremely flexible, they are capable of being fashioned into an endless variety of shapes and sizes. With quality and durability in mind, the heaters are designed into a wide range of standard and customized products. Heateflex’s heating products are designed to heat various process fluids including chemical solutions like SC1 and Piranha solution. In addition, the heaters are built to heat inert gases, deionized water, and other aggressive chemicals.

Furthermore, Heateflex manufactures microprocessor-based temperature controllers using the latest technology to accurately control the temperature of the process fluid. This includes the Heateflex patented Power-to-Flow® protection on our Aquarius® deionized water heating systems which is our latest innovation.

In the early 2000s, Heateflex acquired Fluidix‘s Steam Powered DI Water Heating System to enhance our product line. Throughout the world, these units heat massive amounts of DI Water and allow us to provide large amounts of DI Water to service a complete facility.

The Aquarius® Deionized (DI) Water Heater is the perfect solution for high purity DI Water heating applications where accurate temperature control is required. The Power-to-Flow Control® feature found in the Aquarius provides one of the most accurate temperature controls available in a DI water heating system, and eliminates undesirable overshoots or drops in temperature due to inadequate PID controllers. The Aquarius system is engineered to deliver high flows of continuous, at-temperature, hot DI water. With models from 40kW to 200kW available, the Aquarius system provides an operational cost savings by reducing the need for multiple immersion heaters.
