CASE STUDY
Water-to-water heat pump HYDRA WR-V 650 INV installed at a university in the United Kingdom
Frost Italy has recently completed a custom project based on the HYDRA WR-V 650 INV water-to-water heat pump, intended for a major university in the United Kingdom.
The unit was designed to ensure high energy efficiency, precise thermal control, and maximum operational reliability—key features for complex, high energy-demand buildings such as university facilities.
For this project, a special operation was required: after production and factory testing, the unit was completely dismantled, transported, and then reassembled on site by the Frost Italy technical team. This customised intervention demonstrates the company’s ability to manage complex, highly tailored projects, supporting partners and customers even in the most challenging installation scenarios.
The HYDRA WR-V 650 INV features a reversible water-side cycle, allowing automatic switching between cooling and heating modes, ensuring continuous operation throughout the year.
This configuration ensures:
Reliable operation in all seasons
Optimised energy consumption thanks to inverter technology
High efficiency even under variable load conditions
Maximum flexibility for commercial and industrial applications
