AquaSnap - Water-cooled / condenserless liquid chiller 30RW / 30RWA
AquaSnap - Water-cooled / condenserless liquid chiller
30RW / 30RWA
Refrigerant : R-407C
Compressor : scroll fixed-speed
Nominal cooling capacity : 220-315 kW
The 30RW/RWA AquaSnap liquid chiller range features the latest technological innovations: scroll compressors, digital auto-adaptive Pro-Dialog control and non-ozone depleting refrigerant HFC-407C.
- 30RW Optimized for cooling & heating
- 30RWA condenserless version
- Compact design
- Plug and play approach
- 30RW Optimized for cooling & heating - Heat recovery possible with external PGHE
- 30RWA condenserless version
"Plug and Play" installation
- Integrated hydraulic modules: they minimize site installation complexity and reduce the required space for the chiller installation
Evaporator hydraulic module
- Removable screen filter, single or twin-head water pump, expansion tank, water flow switch, relief valve, pressure gauge, and purge valve
- Control valve to permit adjustment of the flow rate to the water system characteristics
- All components are isolated to prevent condensation
Condenser hydraulic mode
- Removable screen filter, single or twin-head variable-speed water pump, expansion tank, relief valve, pressure gauge, and purge valve
- The variable-speed pump controls the chiller condensing pressure and makes the installation of a three-way mixing valve on the condenser water circuit unnecessary
- Fan control: Pro-Dialog controls the fans of the glycol cooler or remote air-cooled condenser. There are two methods : up to 8 stages maximum with balancing of fan operation times (30RW/RWA), or continuous speed variation (30RWA)
- Quick electrical connection: AquaSnap is equipped with a general disconnect switch and a 24V control circuit supply transformer as standard. A single power supply entry (three-phase without neutral) supplies the chiller.
Economical operation
- Condensing pressure optimized by a patented auto-adaptive algorithm
- At part load or moderate outside temperature an algorithm intelligently controls the condenser water pump speed and the operation of the glycol cooler (30RW) or the condenser (30RWA) fans to maintain the condensing pressure at its lowest possible value
- The standard 30RW chiller can operate down to -20°C outside temperature
- Medium or low temperature brine solution
- HP single or dual pump hydraulic module
- Lon, J-Bus or BacNet gateway
- Master/slave operation
- Soft Starter
- Compliance with Russian regulations
- Welded exchangers connection kit
Pro-Dialog+ control
- Energy management
- Seven day internal time schedule clock
- Set-point reset based on the outside air temperature or the return water temperature or on the water heat exchanger delta T
- Master/slave control of two heat pumps operating in parallel
- Start/stop based on the outside air temperature
- Ease-of-use
- New backlighted LCD interface includes a manual control potentiometer to ensure legibility under any lighting conditions
- Information displayed clearly in English, French, German, Italian and Spanish
- Pro-Dialog+ navigation uses intuitive tree-structure menus, similar to the Internet browsers. They are user-friendly and permit quick access to the principal operating parameters
