Applications

Hygienic Process Cooling & Heating

Provides precise temperature control for low-flow sanitary processes involving pharmaceutical, biotech, food, and personal care products.

Viscous Product Processing

Efficiently heats and cools high-viscosity fluids such as creams, syrups, gels, concentrates, and other difficult-to-process products while maintaining product integrity.

High-Pressure Process Applications

Delivers reliable thermal performance in sanitary systems requiring high operating pressures, large temperature differentials, and compact installation footprints.

Engineered for Thermal Performance

Thermal Stress Management Independent tube expansion design accommodates differential thermal expansion, improving reliability under demanding operating conditions.
Precision Thermal Performance High heat transfer efficiency delivers accurate temperature control for low-flow, high-pressure applications and large temperature differentials.
Maintenance-Free Gasket-free construction eliminates routine seal replacement while avoiding PFAS materials for enhanced environmental safety and long-term reliability.
Sanitary Design Electropolished, fully drainable flow paths support effective CIP/SIP procedures, minimize hold-up volume, and promote hygienic processing.
Compact Footprint Concentric tube construction provides high thermal performance in a compact design, making it ideal for skid-mounted systems and space-constrained installations.

Best Fit For

Use when higher flow, capacity, and sanitary construction flexibility are required.

  • Higher-flow sanitary heating and cooling duties
  • Broader-capacity utilities and product applications
  • Clean steam condensing and sub-cooling
  • WFI and PW temperature control
  • Product sampling and high-purity temperature control

Not Ideal When

  • Extremely low-flow, very high-pressure point-of-use duty
  • Minimal hold-up volume is the primary requirement
