Who Must Keep a Refrigerant Logbook? Under UK F-Gas Regulations, operators of refrigeration, air conditioning and heat pump equipment containing 5 or more tonnes CO2 equivalent of fluorinated gases must maintain a written refrigerant logbook (also referred to as an equipment log or system record) for each system. What Must Be Recorded The logbook must […]
Refrigerant Types Used in UK HVAC Systems UK HVAC engineers encounter a wide range of refrigerant types across heating, ventilation, air conditioning and refrigeration systems. Understanding the classification, properties and correct handling of each is essential for safe, compliant work. HFC Refrigerants — The Current Mainstream Hydrofluorocarbons (HFCs) are the dominant refrigerant family in UK […]
Ordering Refrigerant Gas Online in the UK Buying refrigerant gas online is the fastest and most convenient route for F-Gas certified engineers and refrigeration businesses in the UK. Online ordering gives you access to the full range of trade gases, competitive pricing and next-day delivery without the need to visit a trade counter. Who Can […]
What Is R600a? R600a is the refrigerant designation for isobutane — a natural hydrocarbon refrigerant used almost universally in modern domestic refrigerators and freezers in the UK and across Europe. Its combination of excellent thermodynamic efficiency, very low GWP (3) and zero ODP makes it the clear choice for small, hermetically sealed domestic appliances. Where […]
Safe Storage of Refrigerant Cylinders Storing refrigerant cylinders correctly is both a legal obligation and a practical safety requirement. UK requirements are governed by DSEAR (Dangerous Substances and Explosive Atmospheres Regulations) and the Health and Safety at Work Act, in addition to F-Gas obligations. Core Storage Requirements Store upright with valve caps fitted Secure against […]
Understanding Saturation Pressures for UK Engineers Every refrigeration and AC engineer needs to understand the relationship between refrigerant pressure and temperature. Saturation data is essential for diagnosing faults, setting superheat and subcooling, and verifying correct refrigerant charge. R32 Key Saturation Pressures (Approximate) 0°C evaporating: ~7.2 bar gauge +10°C evaporating: ~9.1 bar gauge +45°C condensing: ~26.0 […]
What Happens to Recovered Refrigerant in the UK? UK F-Gas Regulations require that recovered refrigerant is either reclaimed for reuse, recycled, or destroyed. Understanding the reclaim chain helps engineers comply with their obligations and supports the circular economy for refrigerants. The Three Routes for Recovered Refrigerant Reclamation Reclaimed refrigerant is processed at a specialist facility […]
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 […]
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 […]
