About the SRC50ZS-W
The Mitsubishi Heavy Industries SRC50ZS-W is a high-performance outdoor condenser unit, forming the core of a versatile and efficient split air conditioning system. Delivering a nominal 5.0kW of cooling and 5.8kW of heating, this unit is engineered for reliability in both demanding commercial environments and larger residential properties. As part of MHI's Premium Inverter series, it combines advanced technology with a durable, discreet design, making it an ideal choice for providing year-round climate control in spaces such as offices, shops, restaurants, and spacious homes.
At the heart of the SRC50ZS-W is Mitsubishi's sophisticated inverter technology. Unlike traditional fixed-speed systems that constantly switch on and off, the inverter-driven compressor dynamically adjusts its output to precisely match the heating or cooling demand. This intelligent operation minimises energy consumption, prevents uncomfortable temperature swings, and results in significantly lower running costs. The unit achieves an impressive A++ energy label for cooling, with a high Energy Efficiency Ratio (EER) of 3.7 and a Coefficient of Performance (COP) of 3.72, underscoring its credentials as an energy-saving solution for any property.
The SRC50ZS-W utilises R32 refrigerant, the modern standard for air conditioning systems. R32 offers superior qualities compared to its predecessors, most notably R410A. It has a Global Warming Potential (GWP) that is approximately 70% lower, making it a much more environmentally responsible choice. Furthermore, R32 is more efficient, meaning the system requires less energy and a smaller refrigerant volume to achieve the desired temperature. This contributes not only to a reduced carbon footprint but also to the unit's overall operational efficiency.
Engineered to perform reliably in the variable UK climate, this outdoor unit boasts a wide operational range. It can provide effective heating in ambient temperatures as low as -15°C and cooling in conditions up to 46°C. The physical design is both modern and practical; its compact dimensions and neutral white finish allow it to blend unobtrusively into its surroundings, whether installed at ground level or mounted on a wall. Operation is also remarkably quiet, with sound pressure levels as low as 51 dB(A) during cooling, ensuring minimal acoustic impact on the building's occupants and neighbouring properties.
The SRC50ZS-W offers considerable flexibility for installation. It supports a maximum total pipe length of 25 metres and a vertical height difference of up to 15 metres between the indoor and outdoor units. This generous range allows installers to find the most suitable and discreet location for the condenser, even if it is a significant distance from the indoor space. The unit comes pre-charged with enough R32 refrigerant for a pipe run of up to 15 metres, simplifying the installation process.
This product is the outdoor component of a split system and must be paired with a compatible Mitsubishi Heavy Industries indoor unit, such as those from the SRK-ZS range. When combined, they create a complete system that unlocks a host of user-friendly features. These typically include advanced air filtration to improve indoor air quality, multiple fan speeds, and smart control options via Wi-Fi, allowing you to manage your climate from a smartphone or tablet.
It is a legal requirement in the United Kingdom that any stationary air conditioning system containing fluorinated greenhouse gases (F-gases), such as the SRC50ZS-W, must be installed and commissioned by a qualified and F-Gas certified engineer. This ensures the system is handled safely, operates efficiently, and complies with all environmental regulations. Professional installation is also essential to validate the manufacturer's warranty, providing peace of mind and protecting your investment.

Frequently asked questions
Is this a complete air conditioning system?
No, the SRC50ZS-W is the outdoor unit only. It must be paired with a compatible Mitsubishi Heavy Industries indoor unit to create a full split air conditioning system.
What refrigerant does this unit use?
This unit uses R32 refrigerant, which has a lower Global Warming Potential (GWP) and is more energy-efficient than older refrigerants like R410A.
Can I install this unit myself?
No. In the UK, it is a legal requirement that all stationary air conditioning equipment containing fluorinated greenhouse gases (F-Gas) is installed by a certified F-Gas engineer.
What is the maximum distance allowed between the indoor and outdoor units?
The maximum total pipe length supported is 25 metres, with a maximum vertical height difference of 15 metres, providing significant flexibility for installation positioning.
