Sirac Heat Pump Regassing in Modderfontein
Sirac heat pump regassing in Modderfontein. Modular banks where lead/lag sequencing faults are frequently mistaken for capacity shortfall.
Sirac equipment we work on includes commercial modular heat pumps. Commonly replaced parts on this brand are controllers, contactors, sensors, and we keep or source these against the unit's model and serial plate rather than by guesswork.
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.
Redeveloped industrial estate with a mix of legacy plant and new residential developments. Legacy steam and new heat pump plant both supported. Where a site runs on borehole water, hardness and iron content shorten service intervals considerably and are worth testing before setting a maintenance plan.
