30RB AIR COOLED LIQUID CHILLERS WITH INTEGRATED HYDRONIC MODULE AND PURON REFRIGERANT.

Features:
- Fifteen sizes with nominal cooling capacities from 173 to 760 kW.
- State-of-the-art Aquasnap Puron liquid chillers featuring the latest technological innovation and operating on the ozone-friendly refrigerant R410A.
- All-aluminium micro-channel condenser (MCHX) for extra efficiency.
- Integrated hydronic module (option) with water pump and expansion tank.
- Low-noise scroll compressors with low vibration levels.
- V-shaped condenser coils, allowing quieter air flow across the coil.
- Low-noise 4-th generation Flying Bird fans, now even quieter. Rigid fan installation prevents start-up noise.
- Simplified electrical connection.
- Fast commissioning, as all units are systematically run tested before shipment.
- Economical operation with increased energy efficiency at part load and dynamic superheat management,
- Leak-tight refrigerant circuit and reduced maintenance costs.
- Auto-adaptive control algorithm and automatic compressor unloading for increased reliability.
