Sirac Commercial Heat Pump Regassing in Randpark Golf Estate

Sirac commercial heat pump regassing in Randpark Golf Estate. 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.

On commercial banks, one under-charged unit drags the whole system because the controller keeps calling for heat while a module runs at poor efficiency. Charge correction across a bank starts with identifying which module is losing gas and why — usually vibration fatigue at a joint or corrosion at the coil.
