AquaSnap® - Water-cooled and condenserless liquid scroll chiller & water-sourced heat pump 30WG
Short Description:
General description
- Reduced footprint
- Scroll compressors and R-410A refrigerant
- Variable-flow pump
- Low-noise option (-3 dB(A))
- Stacking of two units for increased capacity (up to size 090)
- Several communication protocols available: JBus, BacNet, MS/TP, LON
- Water connection at the top or rear (30WG)
The right unit for any application
- Option 153 “Built-in DHW and space heating control” allows control of both domestic hot water and space heating requirements:
- Domestic hot water production
- Space heating control
- Control of auxiliary systems
- Pump control
- In 30WG units the pressure controls signal ensures safe unit operation and maximized performance at low source-side water temperatures
- Ideal for refurbishment projects where a remote condenser exists on site, and for all projects without geothermal/natural sinks for heat rejection
Adaptability and simple installation
- Can be provided with several hydraulic module options, both on the evaporator and/or condenser side, with different levels of available pressure and variable or fixed-speed pumps
- If option 153 is selected domestic hot water production is controlled via a built-in three-way diverter valve (not supplied)
Compact high-performance product range
- Small footprint, ideal for refurbished buildings, allows access in very tight plant rooms
- 30WG: High SEER and SEPR. Units optimized for process and comfort applications
- Variable-flow pumps reduce system energy consumption
- The entire range offers low sound levels, allowing installation in any building type. The low-noise option ensures enhanced acoustic comfort (-3 dB(A))
- Equipped with the latest generation R-410A scroll compressor, optimized for typical operating conditions for water-sourced units
