Chillers R32
High-capacity chillers from Flow Wärme for commercial and industrial HVAC applications. Scalable capacity from 34 to 140 kW heating and 29 to 130 kW cooling — with Full Inverter technology, precise temperature control and 7-inch colour touchscreen.
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
