About White Knight
White Knight Fluid Handling Inc., a subsidiary of Graco Inc. (NYSE: GGG), was established in 1995 and has consistently developed and manufactured high quality products in the most demanding applications for leading semiconductor companies.
White Knight manufactures ultrapure fluid handling products for fabricating semiconductors, solar cells, LEDs, Flat-panel displays and electronics, chemicals manufacturing, and industrial applications. Our specialized equipment is used to deliver, circulate, dispense, and reclaim high-purity fluids for wet processes utilizing deionized water, corrosive alkaline or acidic chemical solutions, and toxic liquids such as fuels, glues, paints, resins, inks, and wastewater.
White Knight pumps offer superior performance, optimized efficiency, and simplified maintenance. Their leak-proof designs provide constant, reliable, and safe operation. White Knight provides the highest quality products through controlled, consistent in-house engineering and manufacturing. White Knight ultrapure bellows pumps are assembled, tested, and packaged in a Class 100 clean room. Other White Knight high-purity products include high-purity diaphragm pumps, metering pumps, debubblers, filter housings, pressure regulators, pressure vessels, closed-loop systems, and accessories such as fiber-optic stroke and leak detection, control options, pulsation dampeners, and pre-filters.
White Knight’s Heateflex and Imtec product lines include complete, turnkey fluid and gas heating systems for high-purity applications, including deionized water heaters, in-line Accuheat heaters, inline PFA heaters, inline PFA/PVDF heaters, immersion tank heaters, heat exchangers, wet process tanks, megasonic cleaning systems, and IPA vapor dryers.
Synergies among White Knight, Heateflex, and Imtec products offer enhanced efficiencies to improve high-purity systems. This is part of an overall strategy to deliver expanded product lines, technologies, and services to a constantly growing list of high-tech customers in the worldwide semiconductor and solar markets.
Since 1974, Heateflex led the way in providing ultrapure heating solutions to semiconductor, life science, food and beverage, medical devices, and many other industries. Over the years, Heateflex built a reputation for providing high-quality, performant, and reliable products. In July 2019, Heateflex was acquired by White Knight Fluid Handling Inc.
Heateflex maintains high standards to meet stringent demands for increased safety, quality, and performance. Our engineering team strives to design products that better combine our customers’ needs with improved material technologies. We offer a variety of equipment for heating high-purity fluids and gases, including chemical heaters, deionized water heaters, gas heaters, and heat exchangers. Our products are able to control temperatures with 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.
Since 1972, Imtec has consistently provided high-quality products for rapidly changing markets and technologies. We are committed to providing the finest wet-processing systems to the international semiconductor manufacturers, OEM tool makers, labs, and universities from all over the world. Imtec was the first company to introduce quartz recirculating baths, and we continue to be the world’s leading supplier of quartz constant-temperature baths. Imtec was also the first to obtain UL safety recognition and CE approval for our ultrapure bath products.
After having supplied high-quality products to a broad customer base of more than 500 semiconductor-related companies, Imtec’s wet process systems and heater modules have been constantly optimized. Our continuous efforts toward product improvement and new product development allow the integration of leading-edge systems.
We are committed to providing quality products and services to the semiconductor and related industries, achieving this mission through quality management systems, complying with industry standard requirements, and continually improving the effectiveness of its products. Imtec achieved ISO 9001 certification to ensure that quality is held to the highest standards when designing, fabricating, and delivering a product line.
Imtec is uniquely positioned to offer integrated capabilities to machine, fabricate, and assemble raw quartz and plastic materials into the finest wet-processing modules and sub systems for use in the international semiconductor and associated industries.
