Econex HWP - R32 Inverter Water Cooled Packaged Range

ARBS 2026 Product Showcase - Coming Soon

The Econex HWP (Hideaway Water Cooled Packaged) range brings lower GWP refrigerants and advanced inverter technology to the proven water loop packaged format - unlocking a practical pathway to decarbonisation without disrupting existing building topologies. 

By utilising R32 refrigerant in managed, low refrigerant volumes (A2L), Econex HWP delivers the environmental step change while remaining installable in the same applications and footprints as legacy water cooled units.



Intelligent control is built in with inverter driven compressors that match capacity precisely to demand and command only the water flow required to condition the space - cutting pump energy, improving part load efficiency, and enabling right sized hydronic infrastructure. A refrigerant cooled inverter drive keeps electronics within optimal temperature bands for robust reliability across varying temperature conditions.

Each packaged unit serves one or two dedicated zones and can be powered directly from the tenancy switchboard, simplifying metering, cost allocation, and fit out planning. The reverse cycle + electric heat variant can intelligently prioritise high efficiency heat pump operation and engage electric back up only when loop temperatures fall too low - delivering significant heating energy savings at part load and de risking reliance on central boilers.

The result is a future ready, easily deployable solution that elevates intelligent building performance while accelerating refrigerant transition and improving lifecycle cost.

Unit efficiencies – Across the new Econex HWP range, EER figures have increased by 23% to 40% and COP figures have increased from between 12% to 24% when comparing the replaced R410A ECO HWP range.
