Thermax vapour absorption machines for waste heat and process cooling.
Overview
Thermax vapour absorption machines are common on South African industrial sites with steam or waste heat — food processing, chemicals and cogeneration plants. We service the full range, from single-effect hot water units to double-effect steam-driven machines.

Troubleshooting
Tap a fault for likely causes, what to check on site, and when to call us out.
Likely causes
What to check
Check pump current draw and listen for cavitation noise at the pump body.
When to call us
Call us — replacing a hermetic solution pump requires breaking vacuum and a full re-evacuation.
Likely causes
What to check
Compare cooling water inlet temperature and steam pressure against the design data plate.
When to call us
Book a performance check — absorption machines are far more sensitive to cooling water temperature than vapour-compression plant.
Likely causes
What to check
Take a solution sample and check inhibitor and pH levels.
When to call us
Rising purge frequency is an early corrosion warning — call us before tubes are lost.
Parts & Spares
Thermax supports Africa from India with a regional service network. Solution pumps, valves and control boards typically land in 4 – 8 weeks; chemicals and instrumentation are quicker.

FAQ
A routine Thermax service starts around R4 500 – R9 500 per unit depending on tonnage, compressor count and site access. Repairs are quoted separately after diagnosis. Send us the nameplate photos through the quote form and we come back with a fixed price within 24 hours.
Yes — we source OEM parts through South African distributors wherever the part is still catalogued. Where a component is obsolete or on long lead time, we offer a tested equivalent and tell you up front which route we are taking and what it does to the warranty.
Absolutely. Most of the Thermax plant we look after in Gauteng is well past its warranty period. We service, rebuild and re-commission older units rather than pushing you straight into a replacement.
We work with the unit controller and integrate it with BACnet, Modbus or your existing BMS head-end. That includes alarm mapping, trending, setpoint scheduling and getting fault history off the panel so we can see what actually tripped.
Same-day across Johannesburg, Pretoria, the East Rand, West Rand and the Vaal Triangle. Mpumalanga, North West, Free State and Limpopo are typically next-day, sooner for critical plant.
Yes — quarterly or bi-annual planned maintenance with logged readings, refrigerant records, water-side checks and a written condition report each visit. Contract clients get priority breakdown response.
