Elevating the efficiency of heating and cooling in commercial and industrial applications

C&F Quadrant is now supplying Keyter commercial heat pumps in Northern Ireland, following on from ITS exclusivity announcement in the Republic of Ireland…

Already available in the Republic of Ireland exclusively through C&F Quadrant’s Dublin office, the Keyter range is now supplied by the Newtownabbey branch. 

Ziran PRO Series air-to-water heat pumps are designed for commercial or industrial applications, with the reversible units offering a heating capacity of between 41kW and 253kW.

Optimised for R290 refrigerant use, the units feature full-inverter technology.

Keyter also have an extensive range of chillers and water to water heat pumps to match any system requirements.


• Reduced refrigerant charge (R290 natural refrigerant class A3) andecological with low environmental impact (GWP=3) and high thermodynamic performance.

• High temperature water production.

• Robust and reliable design integrates leak detection and ATEX extraction fan for maximum safety.

• Carefully insulated to ensure adequate protection of the equipment and reduced noise level for super-quiet operation.

• Units are equipped with an intelligent regulation system to guarantee an optimal defrosting process.


• Compact full-inverter units mounted with semi-hermetic inverter piston compressors and high-quality EC fans ensure the best seasonal performance (SEER/SCOP).

• High-efficiency heat exchangers.

• Extensive operating range with high efficiency and expanded operational limits, operating down to -25°C external temperature at full load.

C&F Quadrant has already supplied two Keyter Ziran Pro R290 high-temperature, air-source heat pumps to a key client in NI, assisting the consultant engineer on specifications to suit the project conditions.

Both units have twin head pumps built in, polyurethane coatings on the coils, stainless steel screws, rivets and clamps and coil protection grilles.
