﻿Refrigerant pipework system is based on aluminium tubes
Following 18 months’ successful experience in the USA with VRF air-conditioning systems, FSW is making a refrigerant-pipework system using aluminium available in the UK. It uses the Reflok system to make connections without the use of heat. These connections can withstand pressures up to 100 bar, about double that of copper, and the system has gained UL207 standard approval in the USA. Aluminium pipework systems can also handle CO2
Aluminium tube is much cheaper than copper and, despite the cost of the fittings, installed cost is about the same — with the benefits of faster installation. Reflok connectors are claimed never to have failed in the field.
