Sanyo offers cost saving upgrade from R22 to R410A

Great news for contractors and end users — Bob Cowlard

Sanyo Air Conditioners has developed a new approach to converting existing R22 air-conditioning systems to use R410A. The cost of such a conversion is reduced by about 30% by using existing refrigerant pipework. The Renewal system can be used with virtually all types of R22 systems from leading manufacturers. On most installations, existing wiring can also be used. Any flare connections are replaced to enable the system to accommodate the higher working pressures of R410A. There are also significant ongoing savings in energy costs.’

Bob Cowlard, Sanyo’s sales and marketing general manager, says, ‘The arrival of R22 Renewal is great news for both contractors and end users. There is a huge amount of R22-based equipment out there. With the ban on use of virgin R22 for servicing coming into force at the end of 2009, people with R22 systems are seriously exposed.’

With PACi split systems, installers make a simple oil test to establish that the system has not been subject to a burn-out. Pipework is checked to ensure it is not damaged and that wall thickness are within acceptable guidelines.

For VRF systems, checks are also carried out on pipe lengths and branch networks to ensure they meet current design criteria.

Existing indoor and outdoor units are then replaced with current products from Sanyo’s range. For VRF systems, any of the company’s range of 2- or 3-pipe options can be applied.

Renewal can also be used to replace R407C systems.
