Expert Refrigeration Gas Recharge Services

Refrigerant gas, often mistakenly called 'freon' (a brand name for certain refrigerants), is the lifeblood of your refrigeration system. It circulates through a closed loop, absorbing heat from the refrigerated space and releasing it outside, creating the cooling effect. Unlike a car's air conditioning system, a commercial refrigeration system should not naturally 'use up' refrigerant gas.

Therefore, if your system requires a refrigeration gas recharge, it almost invariably indicates a leak within the sealed system. Simply adding more gas without addressing the underlying leak is a temporary fix that wastes refrigerant, contributes to environmental damage, and is illegal under F-Gas regulations. Our comprehensive service focuses on identifying and rectifying the leak before any recharge is performed, ensuring a lasting and compliant solution.

A decrease in refrigerant level is almost always due to a leak. Identifying the source of this leak is paramount before any refrigeration gas recharge can occur. Common causes include:

Beyond leaks, other issues can mimic refrigerant loss, such as a faulty compressor, blocked expansion valve, or a dirty condenser coil, leading to poor cooling performance. Our diagnostic process distinguishes between these issues to ensure the correct repair is carried out.

• **Vibrations and wear:** Over time, system vibrations can cause copper pipes to rub, leading to hairline cracks, especially at bends or where pipes are secured.
• **Corrosion:** Exposed pipework, particularly in humid or corrosive environments (e.g., near certain chemicals or salt air), can corrode, weakening the material and creating leaks.
• **Poor installation or repairs:** Improper flaring of pipework, loose connections, or poorly soldered joints from previous work can be immediate or long-term leak points.
• **Damage:** Accidental physical impact during cleaning, maintenance by untrained personnel, or general wear and tear can compromise the integrity of components like evaporators or condensers.
• **Faulty components:** Defective Schrader valves, worn seals, or compromised brazed joints can also allow refrigerant to escape.

Our approach to refrigeration gas recharge is thorough and compliant. When you call BritOne Air, our F-Gas certified engineers follow a stringent process:

Once the system's integrity is confirmed, we perform the refrigeration gas recharge using the correct type and amount of refrigerant specified by the manufacturer. The system is then rigorously tested for optimal performance, ensuring it reaches and maintains the desired temperatures efficiently. We provide detailed documentation of the work completed, including the amount and type of refrigerant recovered and recharged, as required by F-Gas regulations.

• **Initial Assessment:** We start with a comprehensive inspection, checking for obvious signs of leaks like oil stains (refrigerant often mixes with a small amount of oil), frost patterns on coils, or unusual noises.
• **Leak Detection:** Utilising advanced leak detection equipment, including electronic sniffers, UV dye, and nitrogen pressure testing, we pinpoint the exact location of the leak. Nitrogen pressure testing is a crucial step that allows us to pressurise the system with an inert gas, making small leaks audible or visible with soapy water, without releasing harmful refrigerants into the atmosphere.
• **Refrigerant Recovery:** Before any repair, all existing refrigerant is safely recovered from the system using specialised recovery units, preventing its release into the atmosphere. This is a legal requirement under F-Gas regulations.
• **Leak Repair:** Our engineers then skillfully repair the identified leak. This could involve brazing, replacing faulty components, or re-sealing connections, ensuring a durable and robust fix.
• **Vacuum and Dehydration:** After the repair, the system is evacuated to a deep vacuum. This process removes any non-condensable gases and moisture, which can severely impair system performance and lifespan if left unchecked.

The handling of refrigerants, particularly fluorinated greenhouse gases (F-Gases), is strictly regulated by the F-Gas Regulation (EU) No 517/2014, which is upheld in the UK. BritOne Air, trading as UK Gas Plumbers Limited, is fully compliant with all F-Gas regulations. All our refrigeration engineers are F-Gas certified, meaning they possess the necessary qualifications and expertise to safely and legally handle, recover, install, service, and decommission refrigeration equipment containing F-Gases.

We maintain accurate records of all refrigerant movements, leak checks, and service activities for every system we work on, ensuring full traceability and compliance for your business. This is crucial not only for environmental protection but also for avoiding potential fines and ensuring the ongoing validity of your equipment warranties. For food service establishments, this compliance directly impacts food safety, as reliable refrigeration prevents spoilage and adheres to HACCP principles.

Regular maintenance is key to preventing refrigerant leaks and extending the life of your refrigeration equipment. We recommend:

BritOne Air offers tailored planned preventative maintenance contracts designed to keep your systems running efficiently and compliantly, reducing the likelihood of unexpected breakdowns and costly emergency repairs.

• **Routine Leak Checks:** Schedule regular F-Gas leak checks as per regulatory requirements (frequency depends on refrigerant charge size).
• **Clean Coils:** Keep condenser and evaporator coils clean and free from dust, debris, and ice build-up to ensure optimal heat exchange.
• **Inspect Pipework:** Periodically check for any signs of physical damage, corrosion, or oil stains along refrigerant lines.
• **Monitor Performance:** Be vigilant for any changes in cooling capacity, increased running times, or unusual noises, which can be early indicators of a problem.

Deciding whether to repair a faulty system or replace it can be challenging. Our engineers provide honest, expert advice based on several factors:

We provide transparent assessments, detailing the cost of repair versus the potential long-term benefits of replacement, allowing you to make an informed decision that best suits your operational needs and budget.

• **Age of the system:** Older systems (typically beyond 8-10 years) may be less energy-efficient and more prone to further failures.
• **Cost of repair:** If the repair cost approaches or exceeds 50% of the replacement cost, replacement often makes more financial sense.
• **Availability of parts:** For very old or obsolete models, parts can be difficult or impossible to source.
• **Refrigerant type:** If your system uses an obsolete or heavily restricted refrigerant (e.g., R22), replacement with a modern, F-Gas compliant system is often advisable.
• **Energy efficiency:** Newer systems offer significantly better energy efficiency, leading to lower running costs over time.
