The use of CFC, HCFC and HFC refrigerants over the past few decades has been a minefield in terms of which refrigerants to use & legislation applied to them.


With good reason we have seen the phasing out of CFC refrigerants in the 1990’s and more recently the banning of HCFC R22 and its derivatives (in virgin form), allowing only recycled R22 to be used in the short term (until 2015) and perhaps more confusingly the introduction of many new HFC refrigerants.


This has left end users with older refrigeration and air conditioning equipment that are still operating with   (H)CFC refrigerants with a dilemma - do we replace or do we retrofit our equipment with another refrigerant?


If equipment is functioning well but has lost some or all of its refrigerant charge then it is likely it can be retro-fitted with a suitable replacement or “drop in” refrigerant which can save capital outlay and system down time whilst extending the equipment useful life.


We have the in-house capability to both assess your system and advise on the best retrofit option available to meet your requirements or specification.


We are a REFCOM registered company and our engineers have the latest C&G 2079 Category 1 F-Gas certificate as required by current legislation together with CITB Brazing & Pipework certificate to EN 378.

Current Issues & Legislation

Vapour compression refrigeration cycle

F-Gas Regulations.
(EN 842/2006)

F-gas Regulations have now come into force. The main objectives of the regulations are to reduce emissions of flourinated greenhouse gases used as refrigerants through better containment and leakage prevention.

What are your Legal Responsibilities?

As an operator of air conditioning, refrigeration or heat pump equipment which contain HFC's you are now legally required to maintain records covering the maintenance of equipment and any refrigerant added to or reclaimed from your systems.

How can TVR Ltd help?

We can help by providing competitively priced maintenance contracts for your equipment, ensuring suitably qualified personnel provide the necessary leak testing and record keeping to meet your F-gas legal responsibilities.

TVR Ltd is a REFCOM registered company which is a legal requirement for all companies dealing with the handling of refrigerants.

Ozone Depleting Substances (ODS).

(EN 2037/2000)

This regulation is in place to reduce the emissions of ODS by legally requiring systems containing more than 3 Kg of refrigerant to have an annual leak check by competent personnel. It will also oversee the phasing out of HCFC refrigerants, namely R22. These refrigerants will no longer be available in virgin form for maintenance or repairs from the end of December 2009.

Energy Performance Certificates (EPC).

Air conditioning systems >12Kw capacity (individually or collectively) now require an EPC by law. TVR Ltd are accredited Energy Assessors and can carry out on your behalf energy assessments which lead to certification, lodgement and recommendations for efficiency improvements which will save you money.

Enhanced Capital Allowance (ECA) Scheme.

The ECA scheme allows businesses to offset the full capital cost of certain energy efficient installations against their tax liabilities in the first financial year. To take advantage of the scheme the equipment used must be on the government ECA equipment list.

Ground Source Heat Pumps (GSHP).

We can supply and install GSHP and Air Source Heat Pumps (ASHP) to provide both space heating and hot water for domestic and commercial premises.
