R407C and R410A in UK Commercial AC R407C and R410A are two of the most common refrigerants in the UK commercial air conditioning installed base. While both are A1 non-flammable HFC blends used in similar-looking split and multi-split systems, they have distinct properties that affect how they are charged and serviced. Key Differences at a […]
Buying Refrigerant Gas in the UK: What Engineers Need to Know Purchasing refrigerant gas in the UK is straightforward once you understand the regulatory framework, cylinder options and what to look for in a reliable supplier. Who Can Buy Refrigerant Gas? Under UK F-Gas Regulations, fluorinated refrigerants may only be supplied to and used by […]
R507A and R404A: Two Refrigerants, Similar Applications R507A and R404A are both HFC blends widely used in UK low-temperature commercial refrigeration. They are often specified for similar applications — frozen food display cabinets, blast freezers, cold stores and transport refrigeration — and are frequently compared when engineers specify or service low-temperature systems. Key Differences Composition […]
The Shift From R410A to R32 in UK Air Conditioning The UK air conditioning market has been transitioning from R410A to R32 for several years. Understanding the differences between these two refrigerants helps engineers, installers and building managers make informed decisions about new installations and system replacements. Side-by-Side Comparison Property R410A R32 GWP 2088 675 […]
Why Natural Refrigerants Are Growing in the UK Natural refrigerants — CO2, ammonia (R717) and propane (R290) — are gaining ground in UK refrigeration and air conditioning as the pressure to move away from high-GWP synthetic refrigerants intensifies. Unlike HFCs, natural refrigerants have negligible direct climate impact and are not subject to F-Gas phase-down quotas. […]
Does Your AC Need a Refrigerant Top-Up? A correctly installed and leak-free AC system should retain its full refrigerant charge indefinitely — refrigerant is not consumed in normal operation. If the system is low, it means there is a leak somewhere in the circuit. Adding gas without fixing the leak is both illegal under F-Gas […]
The End of R22 in the UK R22 (chlorodifluoromethane) was the workhorse refrigerant of UK air conditioning and refrigeration for decades. As an HCFC, it contains chlorine and was found to contribute to ozone layer depletion. The UK, as part of its obligations under the Montreal Protocol, banned the use of virgin R22 from 2010 […]
Refrigerant Selection in UK Commercial Refrigeration Commercial refrigeration encompasses a wide range of applications — from small under-counter cabinets to large industrial cold stores. The right refrigerant depends on the application temperature range, system size, energy efficiency targets and F-Gas compliance requirements. Common UK Commercial Refrigeration Refrigerants R404A — Legacy Medium and Low Temperature R404A […]
Choosing the Right F-Gas Qualification in 2025 Holding a current F-Gas qualification is mandatory for UK refrigeration and air conditioning engineers. With heat pump installations rising rapidly under the Boiler Upgrade Scheme and refrigerant phase-downs accelerating, demand for trained engineers has never been higher. Main UK F-Gas Qualifications City & Guilds 2079 The most widely […]
Refrigerants in UK Refrigerated Transport Refrigerated HGVs, vans and trailers rely on transport refrigeration units (TRUs) to maintain temperature-controlled loads. F-Gas regulations apply to mobile refrigeration equipment just as they do to stationary systems. Common TRU Refrigerants R404A — Legacy Standard Until recently, R404A was dominant in Thermo King and Carrier TRUs. With a GWP […]
