Uncompromising Build Quality

True reliability starts from within. We integrate only world-class components into our systems. Hover over the blue markers to explore the robust architecture and intelligent design that guarantee stable cooling for your critical processes.

LW025L2 water cooled low temp chiller

Transparent, clear door for the controller panel protects against water splashes and prevents accidental setting changes.

SENHO intelligent controller designed specifically for chillers, featuring a clear and intuitive user interface.

Engineered specifically for low-temperature fluids, ensuring smooth, high-pressure circulation in extreme cold.

Premium world-class low-temp compressors (scroll, piston, or screw) delivering superior reliability and energy efficiency.

Oversized evaporators optimized for glycol and brine solutions, maximizing heat transfer and cooling efficiency.

Standard Features

  • Advanced Microprocessor Control: Delivers comprehensive system monitoring, precise temperature regulation, text display, and audible running failure alarms.

  • Premium European Electrical Components: Utilizing genuine Schneider Electric parts built to withstand industrial demands. This higher standard against circuit aging ensures stable performance and an extended service life for your water cooled glycol chiller.

  • Top-Tier Refrigeration Compressors: Engineered for reliable low-temperature cooling. We utilize Danfoss or Copeland scroll compressors, or Bitzer reciprocating compressors for extreme temperatures below -15℃. For larger capacities, Bitzer or Hanbell semi-hermetic screw compressors feature four-grade capacity control for energy-saving, grid-friendly operation.

  • High-Efficiency Heat Exchangers: Featuring generously sized shell-and-tube condensers with an optimized inner structure to minimize blockage risks. Paired with high-quality shell-and-tube or brazed plate evaporators, they guarantee maximum thermal transfer efficiency for any demanding water cooled brine chiller application.

  • Integrated Hydronic Module: Our PLW series features a “plug-and-play” design, integrating a buffer tank and a large-flow, low-temperature fluid pump. It includes built-in bypass valves for easy pressure adjustment and a tank sight glass for instant water level and quality checks. (This configuration is also available for the CLW series upon request).
