Refrigeration Technician (Commercial Cold Rooms)

The cold chain logistics company in Mthatha needs an HVAC technician who knows both the electrical side and the refrigerant side. Bring a calm head on busy days and you'll be fine.

Location: Mthatha, Eastern Cape. Applicants who already live in the area get looked at first. Weekend work is on a roster, so you won't be on every weekend.

• Pressure test with nitrogen, pull a deep vacuum and charge with R410A, R32 or R134a
• Commission new systems and show the client how to use the controls
