What pressure testing and gas compliance certificates are provided?
Every refrigerant leak detection job closes with a pressure test record and gas handling Certificate of Conformance issued under SANS 10147 by a SAQCC Gas registered technician, plus the HACCP documentation your auditors expect.
What operating envelope do you commission this equipment to?
Quick Service Restaurant Chains run at −20 °C to +4 °C at 50–60% RH, with refrigerant leak detection performed against System-dependent, tested to design pressure. Kitchen downtime closes the store outright
