About the SRC20ZSX-W
The Mitsubishi Heavy Industries SRC20ZSX-W is the high-performance outdoor unit at the heart of the premium Diamond Inverter series. Engineered for superior performance and exceptional reliability, this 2.0kW model serves as the robust engine for a sophisticated split air conditioning system, making it an ideal choice for climate control in UK homes, small offices, and light commercial spaces such as retail boutiques or cafes.
At its core, this unit is built around advanced inverter technology which allows it to precisely modulate its power output to meet the exact demand of the room. This results in significantly lower energy consumption compared to traditional fixed-speed units and contributes to its outstanding Energy Efficiency Ratio (EER) of 6.45. It delivers a nominal cooling capacity of 2.0kW and a powerful heating capacity of 2.7kW, ensuring comfortable temperatures all year round. Paired with a compatible indoor unit, the complete system achieves the highest A+++ seasonal efficiency ratings for both cooling and heating.
Environmental responsibility is a key feature of the SRC20ZSX-W. It operates using R32 refrigerant, a modern alternative which has a much lower Global Warming Potential (GWP) than older R410A refrigerant. This not only reduces the system's carbon footprint but also enhances its overall efficiency. The unit's design also prioritises acoustic comfort, with operating sound levels of just 43 dB(A) for cooling and 45 dB(A) for heating, ensuring it operates unobtrusively without causing a disturbance in quiet residential neighbourhoods.
Installation flexibility is a major advantage. The SRC20ZSX-W supports a maximum piping length of 25 metres and a height difference of 15 metres, providing a wide range of options for positioning the indoor and outdoor units in various property layouts, from terraced houses to multi-floor office spaces. Its compact and modern housing (640mm x 800mm x 290mm) is designed to be discreet and blend into its surroundings. Please be aware, the SRC20ZSX-W is an outdoor unit and must be combined with a compatible MHI indoor unit (such as the SRK20ZSX-W) to create a functional system. Installation must be carried out by a qualified F-Gas certified engineer to comply with UK regulations and to validate the manufacturer's warranty.

Frequently asked questions
Is this a full air conditioning system?
No, the SRC20ZSX-W is the outdoor component only. To create a working system, it must be professionally installed with a compatible Mitsubishi Heavy Industries indoor unit, such as the SRK20ZSX-W.
What are the benefits of the R32 refrigerant used in this unit?
R32 is a modern refrigerant with a significantly lower Global Warming Potential (GWP) compared to older types like R410A. It is more energy-efficient and has a smaller environmental footprint, aligning with current environmental standards.
How much noise does this outdoor unit make?
The SRC20ZSX-W is designed for quiet operation, with a sound pressure level of 43 dB(A) during cooling. This is very quiet for an outdoor unit and helps minimise any disturbance to you or your neighbours.
Can I install this unit myself?
No. It is a legal requirement in the UK and EU that any air conditioning system containing F-Gas refrigerants is installed by an F-Gas certified engineer. A professional installation is also essential to ensure safety, performance, and the validity of the manufacturer's warranty.
