Troubleshooting Guide
Tap a fault for likely causes, what to check on site, and when to call us out.
Likely causes
What to check
Watch for a rising solution temperature with falling cooling output and check the concentration trend.
When to call us
Call immediately — controlled decrystallisation needs correct heating and dilution or the machine can be damaged.
Likely causes
What to check
Log daily purge operation and compare shell vacuum against the manufacturer's baseline.
When to call us
Any measurable vacuum decay needs a helium or pressure leak test before performance collapses.
Likely causes
What to check
Compare pump current draw and noise against commissioning values.
When to call us
Rising current or unusual noise means schedule a pump overhaul before an unplanned shutdown.
Likely causes
What to check
Review lockout history and inspect flame quality and sensor condition.
When to call us
Burner work is specialist and safety-critical — book a combustion tune rather than adjusting it yourself.
FAQ
Quarterly inspection and an annual major service including leak testing, inhibitor and solution analysis, and purge verification. Direct-fired machines add an annual combustion tune.
Yes. We perform controlled decrystallisation, then find the root cause — usually a leak, low cooling water temperature or a failed dilution cycle — so it doesn't repeat.
Yes, including concentration, inhibitor level and pH, with a written recommendation on dosing or replacement.
Where you already have steam, hot water or engine jacket heat, they cut electrical demand significantly. We can assess your heat source and current performance.
Broad, York, Carrier, Thermax, Hitachi and LG absorption plant, plus legacy machines where parts are still obtainable.
Typically 3–5 days depending on machine size and whether tube work or decrystallisation is involved.
