Recovering high-GWP refrigerant during demolition project
October 09, 2023

Peng Chuan Engineering Construction Pte Ltd was contracted to demolish the Tampines 11 Concourse Building in Singapore.
While surveying the site, it found 104 air-conditioning units containing nearly one ton of R410A, which has a high Global Warming Potential (GWP) if released to atmosphere.
A-Gas contacted Peng Chuan Engineering Construction PTE. Ltd. and offered them an efficient and reliable recovery solution that would prevent the refrigerant being released. It recovered the gas using skill, efficiency and great organisation in partnership with the customer.
The A-Gas technicians recovered the R410A safely while reducing the risk of leakage to atmosphere. Using a highly efficient portable recovery unit, recovery cylinders and a 50-metre hose, the A-Gas team made sure that the project was completed safely and effectively.
Due to successful collaboration between A-Gas and Peng Chuan Engineering Construction PTE Ltd., the refrigerant was safely recovered and made ready for reclamation. In total, the A-Gas team in Singapore recovered 868kg of R410A from the 104 air-conditioning units, preventing its potential release to atmosphere. The customer was satisfied that A-Gas had helped them keep their commitment to Corporate Social Responsibility and carried out a large-scale project to a high standard.
This is a great example of A-Gas supporting its partners to provide Lifecycle Refrigerant Management (LRM) solutions. A-Gas proved that it could work with customers across many sectors to support them with their environmental goals and establish itself as a leading Lifecycle Refrigerant Management company in Southeast Asia.
