Oasis liquid cooled chillers are designed to deliver high-efficiency cooling for large commercial and industrial facilities, offering cooling capacities from 26 kW to 410 kW. The units are ideal for office buildings, hospitals, hotels, data centers and process cooling applications where cooling demand is high and often continuous. By utilizing liquid as the heat rejection medium, the system benefits from stable temperature control, optimized compressor operation and improved seasonal energy performance. The same Oasis platform can also be configured as a water-to-water heat pump, allowing the system to provide heating when required. The absence of air-side components eliminates the need for defrost cycles and ensures trustworthy performance even in colder climates when connected to groundwater or closed-loop water systems.
Built with reciprocating compressors and BPHE heat exchangers, the system ensures optimized heat transfer and long-term durability. The unit is available with 1 to 4 independent refrigeration circuits, allowing improved part-load efficiency and operational security. In multi-circuit configurations, the unit can maintain partial cooling capacity even if one circuit is temporarily out of service, minimizing downtime and protecting critical processes. Operating with natural refrigerant propane (R290), Oasis liquid cooled chillers combine outstanding thermodynamic performance with ultra-low global warming potential. Designed in line with the latest F-Gas regulations, they offer a future-ready cooling solution that aligns with sustainability goals. 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 liquid cooled chillers 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.
Please note, these products can be also customized to meet specific project requirements.
