Flex Air-to-Water Heat Pump
Cooling capacity: 86 - 147 kW
Heating capacity: 84 - 149 kW





- High part load efficiency
- Year-round hot water supply: Optimized to provide hot water for space heating and sanitary purposes, even in summer. Also delivers chilled water for air-conditioning, operating even beyond 45°C ambient air temperature.
- High flexibility: ability to connect up to six Flex units of similar frames to one single Multimanager controller
- Partial heat recovery (optional)
- Quiet operation thanks to XXLN version, that has an enhanced sound proof insulation and dedicated fans.
- Slim design: ideal to fit in elevators for projects with difficult access (width 1100 mm, height without fans < 2000 mm)
Compact: models just 1.1 meter wide
Flex units can be easily lifted and moved. They fit through doorways and into standard elevators, making them a perfect choice for challenging projects involving replacement in older buildings and/or confined spaces.
Ultimate modularity - scalable up to 900 kW heating capacity
Flex's modularity is ideal when capacity extension is required as the building demand or process cooling demand evolves.
Up to 6 units can be combined and connected thanks to an optional dedicated hydraulic connection kit.
The Multmanager controller based on Symbio 500 proprietary hardware and software can manage a cascade up to 6 units, pumps management in case of shared pump(s), diagnostics, collector inlet and outlet temperature probes.
Leaving hot water temperature up to +60ᴼC
Extensive operational range to meet the specific design requirements of applications like hospitals, office buildings, large apartment complexes, warehouses, and industrial settings.
Capable of maintaining hot water temperatures up to +60°C even in summer time. Additionally, an optional 3-way valve is available for the production of hot sanitary water. This 3-way valve kit can redirect the water flow to a dedicated tank for domestic hot water (DHW) production and is fully compatible with the buffer tank option installed within the unit footprint.
Flex are available in 6 different cooling capacities. Features can be optimized to suit the building’s size, cooling demand and function. Size 026 features DC inverter compressor.
