To face the crisis
Today ref/ac service sector in Sri Lanka face the crisis of non availability of refrigerants for servicing equipment.

Virgin refrigerant cylider general price is rs. 60000 upward.

In this period technicians must practice recovery and reuse refrigerants. Technicans them self can purify the recovered refrigerants by practising self recycling technology.

They themself can check the quality of recycle refrigrants by measuring the pressurers

However, it is noted that charge contaminated refrigetants to the systems are harmful

This is kind attention for all ref/ac service sector technicians.

Clarifications are welcome
