Why Advanced Cooling for BESS Matters

Modern BESS installations face extreme environments, complex integration needs, and the constant demand for longer battery life. The right cooling solution not only protects your investment, but it empowers greater performance and efficiency all year round.

Inside the VLV 4 & 12: Compact, Off-grid

Designed for seamless installation inside BESS containers or cabinets, the new VLV 4 & 12 Chillers bring:Product image of VLV 4 & 12 Chiller BESS Chiller

  • Direct DC Power Supply: Accepts 570–800V DC straight from the battery, no conversion needed. This means simplified system design and greater energy efficiency.
  • All-Climate Operation: Performs reliably from -13°F to +113°F.  Its internal heater ensures optimal liquid temperature in winter, safeguarding battery life even in the coldest climates.
  • Cutting-Edge Efficiency: Variable frequency drive (VFD) tech, a micro-channel condenser, and EC fans deliver significant energy savings and robust performance.
  • Space-Smart Design: A slim profile with a unique structural notch allows easy mounting in tight spots, ideal for maximizing use of every inch.
  • Easy Integration: Modbus TCP communication ensures seamless linkup with Battery Management Systems.

Did you know? The VLV 4 & 12 are protected by two patents, one covering its distinctive shape and another for its innovative DC power source.

Meet the DMC 8.0: Flexible, Space-Saving

If your project needs a solution that excels in both performance and installation options, the DMC 8.0 Chiller is ready to deliver:
