R22 Refrigerant Legislation

R22 Refrigerant Legislation

New legislation brought in under The Kyoto Protocol is enforcing the removal and replacement of the low temperature refrigerant- R22 refrigeration system. These changes in legislation will affect any company that sustains the need for or has a requirement for R22 refrigeration.

Why are the R22 legislation changes being made?
R22 refrigerant has a detrimental effect on the ozone layer resulting in excessive UV levels. Due to this, the R22 refrigerants may contribute to further environmental damage. Watkins Hire like many affected companies have taken the opportunity to comply with the new regulations earlier than planned.

This is being demonstrated at two levels:
Firstly, the majority of R22 refrigeration units are at least one third of their way through their foreseeable life. As existing R22 refrigeration systems begin to require replacing, the majority of companies are choosing to phase these out rather than go to the expense of needlessly repairing or maintaining them.

Secondly, all new air conditioning systems will now use refrigerants such R407c and R410a which have zero or very little ozone depleting potential. These refrigerants are also proven to be more energy efficient than the R22 refrigerant and are therefore a wiser and more popular choice for the companies in question.

What are your companies alternatives to R22?
Most companies that are affected by the R22 legislation will have a policy to specify only the following environmentally friendly refrigerants are incorporated in new air conditioners, chiller equipment:, R404A and R407c. The chosen alternative is decided at business unit level and is usually dependant upon the business’ requirements towards energy efficiency.

When do the changes have to be completed by?
Although many companies have undergone, or are in the process of exchanging their R22 refrigerants, huge conversions still need to be undertaken to ensure that the 2010 deadline for replacement of equipment and the 2015 deadline for completely phasing out R22 refrigerants is accomplished.

R-22: THE IMPLICATIONS OF NEW LEGISLATION

If your air conditioning system is over six years old now is the time to check out this legislation. From 1 Jan 2010 it will be illegal to use virgin HCFCs such as R-22 when servicing and maintaining air conditioning equipment.

If your air conditioning system is over six years old now is the time to check out thislegislationFrom 1 Jan 2010 it will be illegal to use virgin hydrochlorofluorocarbons (HCFCs) such as R-22 (which has been the most commonly used refrigerant) when servicing and maintaining air conditioning equipment.Until the 31 December 2014 temporary use of recycled/recovered R-22 is possible but availability could be limited and costs high. From 1 January 2015 sales or use of recycled/recovered R-22 will be prohibited.

The regulation also calls for all operators of HCFC refrigeration systems to take “all precautionary measures practicable” to prevent and minimise leakage.It states that all fixed equipment systems with a refrigerant charge greater than 3kg will require an annual check for leakage. This must be undertaken by qualified personnel and they will be required to properly recover any HCFC refrigerant removed from a system.

All of Watkins Hire chillers and air conditioners utilse R407C , R410a & R134 during your R22 phase out or replacement we are the only Chiller rental company that complies 100% with the pending legislation.

Floor drying

Heating boiler hire project application
Building hand-over date falling behind due to high moisture content in the floor screed and associated slow drying caused by inclement weather conditions and building not being “air tight” resulting in ;-
1. Floor screed too wet to lay new vinyl flooring though out new building of 3,500 m2.
2. Delay (by M & E Contractor) of newly installed boiler & heating services not ready in time to assist drying.
(The client previously used Aggreko with IDF heaters with lots of ducting throughout building “which were expensive and took a very long time”).

Application requirement
Dry floor screed to four designated “phases” of the building each at different times and speeds to be in line with estimated floor layers work.

The Solution
Supply two Watkins Hire MBR 250kw mobile boilers & GSM monitored 3000-litre fuel tanks c/w pipe work and appropriate tee manifolds to the designated newly installed under floor heating system.

Following the recent inclement weather conditions, Watkins Hire Ltd were asked to provide a solution to a major national building contractors problem of appropriately drying out 3,500 m2 of floor screed without causing any associated damage to the floor.
WHL past and current under floor heating projects offer their customers a “one stop” drying solution particularly where the new boiler plant has yet to be commissioned and newly laid flooring needs to be carefully dried.
Specialist hire director Andy Ellis visited the Basildon site and discussed the application with site Mangers Quantity Surveyor.

Andrews 23 year Temperature control hire application experience involving boilers and chillers helped advise the building contractors to utilise the existing under floor heating system connected to two WHL 250kw LPHW boilers.

“The builder required four different floor areas to be dried at different drying rates and times to meet the proposed floor layers programme of works” said WHL’s Andy Ellis, and the process needed well controlled temperature gradients to ensure the drying did not cause other problems.

Each hire boiler was connected to a total of 19 newly installed under floor heating manifolds with low temperature hot water circulating through the temporary pipe work installed by WHL engineers.

WHL’s unique global satellite monitoring (GSM) telemetry system fitted to their equipment also helped the builder to maintain continuity of heating throughout the hire and eliminated any down time and associated problems involving additional refuelling deliveries or possible equipment breakdowns.

Boiler Hire Keeps Christmas Mail Sorting Open

Watkins Boiler Hire supplied a 500kw of Boiler for temporary heating for a temporary Christmas mail sorting office near London. Watkins Boiler Hire maintained heating with a 500kW Boiler and five off 100kw air handlers connected by flexible pipework.

The Facilities Manager said

"Watkins Hire were on site within 2 hours of us placing the enquiry, their specialist sales manager completed his survey and had a solution to our problem whilst still in our office. When all of the options were considered we made the decision to place the contract with Watkins Hire. The operation of the temporary boiler plant room left us with no hesitation that this was the right piece of equipment for the job. Along with the equipment being available and Watkins Hire offering a Web based fuel management service, it leaves us with piece of mind that the staff will have no complaints about being cold."
