Heat Pump Regassing in Randfontein
Heat Pump Regassing in Randfontein covers leak detection first, then correct-charge regassing by weight. Mining and industrial sites with boiler plant and bulk hot water requirements.
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. Water quality testing is included with maintenance in this area.
West Rand visits carry a fuller van stock because parts runs back to Johannesburg cost time. Where a site runs on borehole water, hardness and iron content shorten service intervals considerably and are worth testing before setting a maintenance plan. Control scheduling is often the cheapest available improvement, particularly where heating windows overlap with peak tariff periods.
