As an engineer, I get really excited when I hear that we are launching a new product, and I immediately look at what I might need to add or alter in our training courses to help other engineers understand the technology and how to install it.
Sometimes a new product or range is an upgrade from an existing line up. Yes, it brings new features and benefits but it’s a continuation rather than anything really game changing.
The same cannot be said about the new City Multi R32 YXM VRF air conditioning. This isn't simply just another upgrade!
Our R&D teams have taken their time to look carefully at what the market needs from larger VRF units and examine the special opportunities that R32 offers.
Yes, it promises a 20% reduction in operational carbon and running costs with a 10% increase in energy efficiency, but it’s the changes that affect engineers that excite me as a trainer.

Even more City Multi
So, for installers, designers and maintenance teams, the new R32 YXM range comes with all the familiarity that has rightly made City Multi market leading, allowing unparalleled flexibility in design, installation, commissioning and operation.
This advanced technology will bring substantial cost savings in terms of running expenses, and the best part is that it still maintains the plug-and-play convenience that VRF systems are known for, ensuring easy installation and seamless integration into your projects.
I believe that this combination of innovation and practicality makes our new VRF solution truly exceptional.
The ultra-compact, modular system has a footprint 6% smaller than the market average, saving important space on the roof or in the plant room.
We’ve also extended the height extension between the outdoor and indoor units to 113m, which helps as high-rise buildings are becoming more popular.
The new Branch Controller (BC) box now comes with up to 12 ports and has built-in shut-off valves. It also has a compact height of just 252mm, meaning it can be installed into tight ceiling spaces to increase design flexibility.
There’s also been around 20% improvement in the cooling efficiency and about 30% improvement in the SCOP over previous models making YXM suitable for both for new projects and upgrades, especially where performance and sustainability are key.
And, against an industry average of 10-years for leak detectors, the City Multi R32 YXM offers a 30-year lifespan on the low-level leak detectors.
We’ve looked at everything
We've reduced overall system charge – helping to lower embodied carbon, and improved seasonal efficiency - reducing operational carbon.
The outdoor unit is equipped with a newly designed heat exchanger with aluminium flat tubes but the flow of refrigerant from the main distributor is now done vertically.
This means that, when the system is in full heating or majority heating, the mixture of liquid & gas is directed from a horizontal distributor and fills the coil evenly, thereby using every section of that heat exchanger and improving the phase change.
Additionally, more thinner and closely packed tubes increase the heat exchanger surface area, improving cooling efficiency through a higher density arrangement.
So, the new City Multi R32 YXM range builds on the VRF system the market already knows and trusts, but takes it to the next level with smarter, more sustainable features.
I can’t wait to get the first engineers in for training!
