Heat Pump Regassing in Isando
Heat Pump Regassing in Isando covers leak detection first, then correct-charge regassing by weight. Warehousing, cold chain and light manufacturing with process hot water and boilers.
A heat pump is a sealed system: if it is short of gas, there is a leak. Simply topping up sends the same refrigerant back into the atmosphere within months and masks the fault. We pressure-test, trace the leak, repair it, evacuate to vacuum and then charge by weight to the manufacturer's plate data.
The installed base here is industrial, so most plant is three phase, duty-cycled hard and tied into process or steam distribution. Cold chain and process plant scheduled around production.
Ekurhuleni call-outs are grouped by area so industrial and commercial visits can be attended on the same run. Gauteng municipal water is moderately hard, so scale on elements and heat exchangers is the single most common cause of falling performance. Recovery rate and storage volume have to be considered together; adding heating capacity to undersized storage rarely fixes a peak-hour shortfall.
