Oasis Water-to-Water Heat Pumps

The absence of air-side components eliminates the need for defrost cycles and guarantees trustworthy operation even in colder climates. The same Oasis platform can also be configured as a liquid cooled chiller, allowing the system to provide cooling when required.

Built with reciprocating compressors and high-performance BPHE heat exchangers, the system ensures efficient heat transfer and long-term durability. Thermal energy absorbed from the water source is elevated to a higher temperature level by the compressor and transferred to the building’s heating circuit with consistent and controlled output. The unit is available with 1 to 4 independent refrigeration circuits, enabling improved part-load efficiency and enhanced operational security. In multi-circuit configurations, partial heating capacity can be maintained even if one circuit is temporarily out of service, minimizing downtime and ensuring uninterrupted comfort.

Operating with natural refrigerant propane (R290), Oasis water-to-water heat pumps combine outstanding thermodynamic performance with ultra-low global warming potential. Designed in line with the latest F-Gas regulations, they offer a future-ready heating solution that aligns with sustainability goals and supports long-term energy efficiency objectives. To ensure safe operation with natural refrigerants, Oasis line follows the Class IV ventilated enclosure concept defined in EN378. The refrigerant circuit is housed inside a ventilated enclosure equipped with an integrated leak detector and Delta P for ventilation monitoring. In the event of a leak, non-ATEX components automatically shut down while ventilation safely extracts refrigerant from the enclosure.

Engineered within a robust, fully enclosed frame, Oasis water-to-water heat pumps are suitable for both indoor and outdoor installation. The galvanized steel construction with powder coating provides long-term corrosion resistance, while 20 mm non-flammable acoustic PU foam insulation minimizes operational noise. For projects requiring even quieter operation, a low-noise version with 30 mm rock wool insulation is available. Thanks to its super-compact footprint, the unit can pass through standard door openings, making it an excellent solution for technical rooms. These features make it particularly suitable for installations with architectural limitations, noise regulations, or environmental restrictions. Each unit is factory-assembled and tested, ensuring plug-and-play installation and reduced commissioning time.
