Air-to-water reversible heat pumps with R290 refrigerant

SHEEN PRO (WiSAN-PSE1) is the new Clivet series of air-to-water reversible heat pumps with R290 refrigerant (GWP = 3).

Designed for the commercial sector, it offers you comfort, high energy efficiency with an ErP class of up to A+++ (W35) and A++ (W55), and wide application flexibility.

It is the ideal solution for climate control in both new buildings and the retrofitting or replacement of existing systems, including those with boilers.

It is available in four sizes, with heating capacities ranging from 25 to 59 kW. 

Why choose SHEEN PRO?

Retrofits existing systems

By producing hot water up to 77 °C, it meets your building's needs without requiring modifications to the heat distribution systems when replacing traditional fossil fuel generators. It also ensures hot water production up to 65 °C even with outdoor temperatures as low as -25 °C.

Maintains high performance in harsh climates

The series maintains high heating capacity even at low outdoor temperatures. This reduces the need to integrate auxiliary systems, such as boilers or electrical heaters.

Simplifies installation

Each circuit uses an R290 refrigerant charge of 5 kg or less, effectively reducing the installation constraints associated with the use of propane in accordance with the EN 378 installation and safety requirements.

Optimises consumption all year round

Inverter technology applied to compressors and fans modulates operation based on the building's actual thermal demand, optimising energy consumption even at partial loads. This ensures high seasonal efficiency in both heating and cooling (SCOP up to 4.71 (W35) and 3.52 (W55), and SEER up to 5.10, according to EN 14825:2022).

Ensures application flexibility

You can configure the system by choosing from integrated pumps, buffer tank, and dedicated accessories, and manage Domestic Hot Water (DHW) via an integrated 3-way valve.
