F-gas regulations

Go Back


Hot on the heels of R22 Replacement, changes to F-Gas regulations came into effect in January 2015 after years of consultation and negotiation across Europe.

But how do these changes affect our customers?

Do you know the new threshold limits?

Or how often your equipment has to be checked?

Here at ACE Refrigeration, we can always help you stay compliant with F-Gas regulations, either as part of our service and maintenance contracts, or by installing fixed leak detection units to your refrigeration plant.

Fluorinated greenhouse gases (F-gases) gases are a family of chemicals that contain fluorine.

Most F-gases are very powerful greenhouse gases which contribute to global warming if emitted into the atmosphere.

HFCs (Hydrofluorocarbons) are common F-gases found in air conditioning and refrigeration systems.

The central element of these revised regulations is part of the phase down of HFC Refrigerants with a global warming potential (GWP) greater than 2500, with a complete ban on new equipment using these refrigerants effective from 2020 onwards.

However, recycled and reclaimed HFCs with greater than 2,500 GWP will still be allowed for servicing existing plants until 2030.

The previous classification confirming leak detection quantity per year based on refrigerant charge thresholds have now been replaced by a system based instead on carbon emissions per year.

All systems with a CO2 equivalent greater than 500 tonnes must have a fixed leak detection system installed.

But for any system with fixed leak detection installed, the quantity of leak tests required is reduced by 50%.

*     Leak check frequency is halved if automatic leak detection system is installed

**  The threshold for annual leak checks of hermetically sealed equipment is 10 tonnes CO 2

So do these changes affect you?

Well it depends on what refrigerants your current plant operates with, and how much you are using.

Different refrigerants have differing thresholds; all based on the carbon emissions.

The table below details the comparative refrigerant charge for the refrigerant type based on the new threshold.

A 15% loss of refrigerant can equate to a 50% drop in operating efficiency.

F-Gas leak checks and the legal requirement for leaks and any consequent repairs to be recorded in a maintenance log will help to

  1. Reduce such efficiency losses
  2. Reduce energy costs
  3. Reduce refrigerant gas consumption
  4. Reduce potential stock loss

Under  the  F-Gas  regulations,  system and  equipment  operators  have  an obligation  to  prevent  leaks.

If you operate stationary refrigeration and air conditioning systems, you must prevent any leaks or take action to remedy the situation immediately.

There is now a legal requirement to have all refrigerant leaks repaired, regardless of cost or technical implications; you are risking a fine of up to £5,000 for non-compliance.

Records will also need to be maintained for all equipment with a refrigerant charge of 5 tonnes CO2 equivalent and kept for five years.  This is the responsibility of the owner of the equipment.

Regulations will strengthen existing measures and introduce a number of far reaching changes.  The aim is to cut f-gas emissions across Europe by two thirds compared to 2014 levels.

Here at ACE Refrigeration, we can

  1. Offer a complete F-Gas Audit Service
  2. Devise a Leak Detection Programme
  3. Complete F-Gas Asset list
  4. Complete and update an F-Gas register in accordance with regulations
  5. Supply, Install, Service and Maintain Fixed Leak Detection systems

slide1In February 2015, we installed Leak Detection modules to plant across RK Drysdales site in the Scottish Borders.

One of our existing customers, Drysdales is one of the UK’s top vegetable suppliers; providing British supermarkets with more than 14,000 tonnes of fresh Scottish vegetables all year round.

Previously Drysdales came to ACE Refrigeration when an increase in production requirements created the need for more than 5,500 cubic metres of chilled production space.

ACE were responsible for the design, supply and installation of two chilled warehouses, totalling 3,000 cubic metres of chilled space, plus a 2,500 cubic metre temperature controlled loading bay.

The design incorporated a remote temperature monitoring and management system as well as the installation of a large number of control probes, giving  Drysdales the confidence they required to ensure the total integrity of their products at all times.

ACE Refrigeration also recently installed a new screw compressor pack for William Sword Bakery as they required R22 Replacement for their Spiral Freezer.

As well as replacing the evaporator coil, ACE Refrigeration installed a pack consisting of three compressors offering increased reliability and efficiency – screw compressor packs allow for output to meet demand when applications with varying loads are required.

Leak Detection was also installed as part of this project.
