Company profile
White Knight Fluid Handling, Inc. provides ultrapure pumps, heaters, and wet process tanks for deionized water and chemical applications. With over 35 years of experience, its product selection ranges from air-operated double bellows pumps and DI heating systems to high-purity wet process tanks. Its patented product designs serve the semiconductor, solar, LED, and electronics industries. The company performs engineering and manufacturing in-house and assembles, tests, and packages products in a Class 100 cleanroom. White Knight Fluid Handling, Inc. addresses complex fluid-handling needs, and its products can be tested and can perform reliably in demanding applications and harsh environments.
Exhibits
White Knight pneumatic bellows pumps use PTFE and PFA flow paths, provide high flow rates, steady pressures and stable temperatures, contain no metals or elastomer O-rings, and are leak-free, dead-head capable, and able to provide suction lift. Its pneumatic diaphragm AODD pumps use corrosion-resistant PTFE fluid paths for corrosive or toxic liquids including acids, fuels, glues, paints, resins, inks, and slurry. Pneumatic and electronic metering pumps dispense up to 100 ml and 50 ml, respectively, and use fully supported PTFE rolling diaphragms to increase pressure capability and support safe, reliable chemical dispensing. Mini-pumps provide flow rates up to 300 ml/min and discharge pressures up to 160 psi, use PTFE and PFA fluid paths, and can mount in any direction through spring-loaded checks. In-line and top-mount pulsation dampeners reduce pulsation, improve flow control, increase batch yields, and protect filters, fittings, pipes, and other system components to reduce repair downtime. Universal compact multi-chamber filter housings use PTFE and PFA fluid paths for high-purity chemicals, with dual-bowl and quad-bowl configurations available in parallel or in-line models. White Knight debubblers reduce bubbles in chemical-delivery and wafer-process systems and use chemically resistant PTFE and PFA fluid paths for high-purity chemical applications. Remotely piloted pressure regulators automatically maintain and accurately control pressure for circulation loops or multiple dispense points without additional circuitry or feedback, using fully swept PTFE and PFA flow paths. The iPolymer range includes high-purity Solenoid, Pneumatic, Manual, Suck Back, and Pressure Relief valves with PTFE, PVDF, or Polypro wetted paths; PTFE spray guns for DI rinsing, nitrogen drying, recirculating, and liquid dispensing; PVC, Polypropylene, and PVDF air cylinders with optional position sensors; and PTFE air and liquid aspirators driven by clean dry air or Nitrogen for siphoning gases, water, and chemicals. High-purity closed-loop systems use metal-free PTFE pumps to maintain laminar flow or steady pressure, provide stable temperatures, dead-head operation and suction lift, and are specified for flow rates up to 140 lpm (36 gpm), pressures up to 7 Bar (100 psi), and temperatures up to 210°C (410°F). These closed-loop systems are described as having no metals, elastomer O-rings, electric motors, or impellers, avoiding corrosion, leaks, heat rise, and microbubbles while simplifying high-purity chemical process automation to save time, resources, and costs. White Knight heater offerings include Aquarius® DI water heater systems, HC Series in-line PFA fluid heaters for aggressive acids and chemicals, in-line PVDF fluid heaters for DI water, acids, and less aggressive chemistries, Vesper™ PVDF/PFA heat exchangers for heating, cooling, and temperature trimming, Heateflex PFA immersion tank heaters, Accuheat™ quartz and PFA in-line heaters for chemicals, solvents and gases, and HX50 compact in-line heaters with 50-mm (2-in) housings for low-wattage and low-flow applications. Accuheat™ PFA solvent heaters are listed for Isopropyl alcohol, Acetone, Ethanol, Toluene, EKC, MEK, and NMP; PFA chemical heaters include applications such as hydrofluoric acid (HF) and potassium hydroxide (KOH); and quartz gas heaters are listed for Nitrogen (N2), Ammonia (NH3), Helium (He), Argon (Ar), BCl3, HCl, CO, and CO2. The heater range also includes gas heating systems, industrial water heaters, and immersion heaters for deionized water, chemicals, gases, and solvents, while legacy systems include Aries Solvent Heaters, Fluidix® Steam-Powered DIW Heaters, Poseidon™ Stainless Steel Heaters, SX Stainless Steel Heaters, and Demeter™ Systems. Wet-process offerings include Accubath™ heated quartz baths for quartz-compatible chemistries up to 190°C, Accubath™ PTFE, PVDF, PFA, and NPP wet-process and rinse tanks designed to reduce particles by minimizing welds and seams, and Accubath™ sapphire wet-etch tanks for heating chemistries up to 300°C. Megasonic cleaning systems use high-frequency acoustic energy to remove submicron particles without damaging delicate substrates, with continuous energy delivery, beam scanning, and phase shifting intended to improve cleaning efficiency and reduce chemical use; systems are available in PVDF, PFA, or Quartz tanks. Accumeg™ tanks use gapless transducers with tightly matched crystals wired in parallel for process uniformity, HyperClean™ uses energy-transfer technology for submicron cleaning, lower operating costs and reliability, and RF-generator-coupled transducer modules can retrofit existing tanks or mount as bulkhead transducer plates. The product catalog also lists Bellows Pump series PA, PSA, PSH, PSU, PSR, PFA, PFH, PFU, PXA, PXH, and PXU plus PL60 and AP40EXT3; Metering Pump series PEM, PPM, and PPMC Mini; DI Water Heater Systems, Inline Heaters, PFA Tank Heaters, and Vesper Heat Exchangers; CBA and CBU Debubblers; FHA and FHU Filter Housings and Catcher Pre-Filters; Pressure Regulators, Pressure Vessels, Spray Guns, Manual, Pneumatic, Check, Pressure-Relief, and Solenoid Valves; Accubath Quartz, Plastic, and Wet Etch Tanks; Accumeg and HyperClean Megasonic Systems; and accessories including Closed-Loop Controllers, Cycle Rate Translators, Fittings, Grounding Adapters, Pulse Dampeners, Quick Dump Valves, Temperature Controllers, Air Cylinders, Aspirators, and Gauge Isolators.
