High Temperature Water Filters for Data Center Cooling Systems

Water filtering and purifying machinery and apparatus typically fall under international Harmonized System (HS) heading 8421, specifically subheading 8421.21. Exact classification codes can vary depending on the specific design, materials, configuration, and intended fluid processing function of the equipment.

Operating temperature limits depend on the housing type, basket construction, and selected seal materials. Simplex and duplex stainless steel strainers support operating temperatures up to 500°F (260°C), while multi-bag filter housings accommodate temperatures up to 300°F (149°C) based on the chosen configuration.

Duplex strainers feature a dual-chamber design with an integrated diverter mechanism. This allows process flow to be isolated to one chamber while the alternate basket is accessed, serviced, or cleaned, preventing cooling cycle shutdown and supporting continuous uptime in mission-critical environments.

Equipment options include 304L and 316/316L stainless steel housings for corrosion resistance and high-temperature capability, as well as non-metallic fiberglass options for select high-flow cartridge housings depending on application requirements.

Depending on housing model and operating temperatures, available gasket and seal options include Buna-N, EPDM, EPR, PTFE, graphite, silicone, and Viton (FKM) to ensure positive fluid containment under thermal stress.

Select configurations are manufactured to meet ASME B16.5 flanged standards, ASTM material specifications, ASME Section VIII, Division 1 pressure vessel guidelines, or under ISO 9001 certified quality management systems with material traceability and pressure testing.
