Profile: Kelvin Refrigeration Services Ltd. provides five types of air conditioning systems such as wall mounted cassette, ceiling mounted cassette, twin split system, multi-system and VRF/VRV systems. We are registered under ISO 9001. Cassette is installed discreetly in the ceiling void, and will sit flush to the ceiling grid. It's standard features include auto air flow adjustment to match room conditions, and auto-changeover on the heat pump models to maintain the set temperature. Our twin split system allows the connection of two indoor units of the same type and capacity to one outdoor unit. This gives more even air distribution in a larger area. It is ideal for larger premises and open-plan.
