25 – 75kW PLANT ROOM SERIES
Kensa’s Commercial Plant Room series is comprised of modular three phase ground source heat pumps especially designed for commercial or larger buildings.
- Modular system provides greater flexibility to match the heat pump output to the load of a commercial building.
- With multiple units it is possible to provide heating and cooling to different parts of a building simultaneously via a Building Management System (BMS).
- Specified to allow straightforward interface with a buildings heating distribution system, such as fan coils, underfloor, and air handling units.
- High Temperature model provides heating to 60°C.
- Dimensions HxWxL (mm) – 1750 x 800 x 900
- Heating only models: 40kW, 45kW, 60kW and 75kW produce temperatures up to 55°C.
- High Temperature 25kW model produces temperatures up to 60°C.
- Heating & cooling models: 25kW, 30kW, 40kW, 45kW, 60kW and 75kW.
- High specification acoustic hoods and double vibration isolation reduce noise and vibration.
- Designed to be installed within a plant room.
- Compatible with Building Management Systems (BMS).
- DNO friendly ‘Soft Starts’ fitted as standard to ensure peak starting load is minimised.
- Two temperature set points produce the required heating at the highest efficiency without the need for costly direct immersion heaters.
- Ability to modulate between full and half loads to reduce power consumption and running costs.
- Weather compensation fitted as standard.
- Copeland scroll compressor with a minimum design life of 20 years.
- Ground and underfloor circulation pumps.
- Water pumps available as an optional extra.
- In-built sensors and probes to enable remote commissioning.
- 5 year warranty for the heat pump unit.
- 2 year warranty for the controller and water pumps.
- 2 year internals warranty.
- MCS (25kW – 45kW only)

ᵻ Units are currently being ErP tested and will be available when complete.
^The 45kW Plantroom produces above 50kW at a ground temperature of 0°C and load temperature of 35°C.
+ Cooling only units are not MCS approved.
* The COP figure quoted excludes the water pump electrical input and is calculated according to EN14511.
** In-built immersion heaters will increase running costs and CO2 emissions as they use direct electricity, because of this Kensa heat pumps do not include them.
*** By increasing the flow temperature from the heat pump the efficiency of the unit will drop and the COP decreases.
**** The starting currents are per phase. For full details on how the starting currents are calculated please contact Kensa.
Note i): Design flowrates and pressure drops are based on a ground temperature of 0°C and –4°C and a load temperature of 30°C and 35°C.
Note ii): The P500X unit is classed as a Low Temperature Space Heater as per the ErP regulations.
