The Cooper & Hunter Multi-Split Series offers flexible and efficient air conditioning for small and medium-sized offices.
Designed to balance energy performance, comfort, and compact installation, these systems deliver professional-grade control in modern UK workplaces.
System Configuration
A single outdoor unit can power up to five indoor units, each operating independently.
This design is ideal for offices with multiple rooms or open-plan layouts where precise temperature control is essential.
Indoor units come in wall-mounted, cassette, ducted, and console formats to suit any architectural requirement.
Energy Efficiency
Equipped with DC inverter compressors and R32 refrigerant, Cooper & Hunter multi-split systems achieve:
-
SEER: up to 8.2
-
SCOP: up to 4.7
-
Energy rating: A+++
Power consumption is reduced by up to 35 % compared with non-inverter models.
The system automatically adjusts compressor speed to meet real-time demand, maintaining comfort while minimising energy waste.
Compact and Quiet Design
Outdoor units are compact, making them suitable for installations on balconies or roofs with limited space.
Noise levels are impressively low — 45–48 dB(A) outdoors and 22–28 dB(A) indoors.
This ensures quiet operation in meeting rooms and shared office environments.

Through the C&H App, users can:

Quick-connect fittings and pre-charged refrigerant simplify installation and commissioning.
Air Quality and Comfort
Multi-split indoor units include multi-stage filters and ionisation modules for removing dust, pollen, and bacteria.
Optional Cold Plasma filters ensure a healthier indoor environment — an important feature for modern workplaces focused on wellbeing.
Reliability and Service
