Mitsubishi Electric Air Conditioning Units

City Multi

The City Multi range is Mitsubishi Electric’s answer to VRF (Variable Refrigerant Flow) applications – perfect for large scale air conditioning setups.

The efficiency of City Multi is second to none and offers a substantial increase in energy efficiency, with corresponding EER/COP ratings.

The City Multi Y Series range offers a simple and flexible solution where there is a demand for a changeover capability between heating and cooling, helping to ensure a constant, comfortable indoor climate.


Working alongside air conditioning, Lossnay units can save you up to 30% on initial capital costs of heating and cooling plant, by extracting stale air and then recovering the heating or cooling energy to either warm, or cool, incoming fresh air.

This recovery of waste energy, whilst delivering fresh air ventilation, is very beneficial for schools and offices – it not only reduces running costs, but by improving air quality you can increase productivity, lift morale and reduce rates of sickness.

Good ventilation, alongside air conditioning in residential and commercial buildings, provides the right conditions for people to live and work in comfort and safety.


Mitsubishi Electric’s Ecodan heat pump range is suitable for small to large applications, both domestic or commercial. As a refrigerant based system, they work in a similar way to a refrigerator.

The Air Source Heat Pump (ASHP) absorbs low grade heat from the air, and can efficiently raise its temperature enough to be used for space heating and/or hot water. Alternatively, the Ground Source Heat Pump (GSHP) absorbs from the ground or water, and is used in the same way as the ASHP units. The former is versatile for a wide range of structures, while the latter is produces less CO2 and is the more eco-friendly option for environmentally responsible businesses.

Heat pump technology delivers effective, low carbon heating and hot water. Mitsubishi Electric’s award winning Ecodan systems provide a simple, renewable solution that rivals traditional heating systems.
