Broad absorption chillers — direct-fired, steam and hot-water driven.
Overview
Broad is the largest absorption chiller manufacturer in the world and their machines turn up on South African sites with waste heat, gas or steam available. Absorption plant is a different discipline to vapour-compression — vacuum integrity, solution chemistry and crystallisation control are what keep it running.

Troubleshooting
Tap a fault for likely causes, what to check on site, and when to call us out.
Likely causes
What to check
Check solution temperature differentials and look for a blocked heat exchanger pass.
When to call us
Crystallisation needs a controlled de-crystallisation procedure — call us rather than heating the machine blindly.
Likely causes
What to check
Log purge frequency and vacuum readings against the baseline.
When to call us
Vacuum loss destroys capacity and corrodes internals — call us for a helium leak test.
Likely causes
What to check
Check burner combustion figures and take a solution sample for analysis.
When to call us
Book a service — solution chemistry drifts slowly and only shows up as gradual capacity loss.
Parts & Spares
Broad parts are imported from China — solution pumps, burner components and inhibitor chemicals typically run 4 – 8 weeks. We keep inhibitor and octyl alcohol dosing chemicals available locally for contract sites.

FAQ
A routine Broad 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 Where a component is obsolete or on long lead time, we offer a tested equivalent and tell you up front which route we are taking and what it does to the warranty.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 Broad 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.
