Product Advantages

The Chillers R32 — DualTherm B Range delivers commercial-grade quality with state-of-the-art Full Inverter technology.

Automatic Defrost Technology

Advanced defrost technology optimises the defrost cycle, reduces energy consumption and ensures continuous operation down to -15°C — for efficiency and long-term operational reliability.

Modular Design

Innovative modular approach for minimal footprint, simplified logistics and easy scalability. Multiple units can be run in parallel for larger capacity requirements.

High-Efficiency EC Fan

High-efficiency EC fans optimise airflow and heat dissipation. Focused on durability — maximum energy efficiency without any compromise on reliability.

Twin Rotary Compressor

Fully hermetic construction for robust longevity, minimal vibration — purpose-built for high-volume commercial and industrial applications with continuous full-load operation.

SWEP Plate Heat Exchanger

High-performance SWEP plate heat exchanger increases heat transfer efficiency, minimises pressure loss and ensures stable operation under variable load conditions.

7-Inch Touchscreen & Wi-Fi

Intuitive 7-inch colour controller for convenient on-site operation. Wi-Fi integration for seamless remote monitoring and control — maximum transparency for facility managers.

Eco-Friendly R32 Refrigerant

R32 delivers a Global Warming Potential (GWP) one-third that of traditional R410A — significantly reducing environmental footprint while maintaining high efficiency and excellent performance.

Wide Operating Range

Exceptional flexibility across diverse applications: water heating temperature range 8–55°C, water cooling temperature range 10–35°C — reliable performance in a wide array of environmental conditions.

Modular Scalability

Multiple units can be run in parallel — capacity grows with your project.

Flexible · Scalable · Efficient

The innovative modular design not only minimises footprint but also simplifies logistics and installation. A flexible solution that scales effortlessly as your demand grows.

  • Combine multiple units in parallel
  • Compact footprint per kW of capacity
  • Future expansion without system overhaul
  • Simplified servicing thanks to identical modules

Quiet Operation

Even under full load the Chillers R32 stay pleasantly quiet at 70–80 dB(A) — ideal for rooftop installations in urban settings.

Comfort for People and Surroundings

High-efficiency EC fans combined with the fully hermetic Twin Rotary compressor deliver minimal vibration and a smooth operating profile — even on exposed rooftops or in close proximity to offices and residential areas.

  • 70 dB(A) @1m for the FW-70CHIL
  • 80 dB(A) @1m for the FW-140CHIL at full load
  • EC fan technology for smooth, even airflow
  • Suitable for rooftop and outdoor installation
