Sirac Commercial Heat Pump Regassing in Roodepoort
Sirac commercial heat pump regassing in Roodepoort. 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.
Broad residential base with light industrial parks and a large number of ageing geysers and early heat pumps. Retrofit from element geysers to heat pumps is common here. Gauteng municipal water is moderately hard, so scale on elements and heat exchangers is the single most common cause of falling performance.

We are an independent specialist. We repair and maintain Sirac equipment using correct-specification parts, and where a unit is still under manufacturer warranty we will tell you before doing anything that could affect it.
Can you get Sirac parts?
Controllers, contactors, sensors for Sirac are ordered against the model and serial plate. Where an original part has a long lead time we will offer a compatible equivalent and say clearly which one is being fitted.
What does Sirac commercial heat pump regassing include?
Per-module charge verification, Vibration and joint fatigue inspection, Coil corrosion assessment and coating, plus verification that the unit performs to the manufacturer's stated figures after the repair.
Do you service Sirac units in Roodepoort?
Yes. Roodepoort is inside our service area. West Rand visits carry a fuller van stock because parts runs back to Johannesburg cost time.
Is it worth repairing an older Sirac unit?
Where the tank or coil has perforated, replacement is usually the honest answer and we will say so on site. Modular banks where lead/lag sequencing faults are frequently mistaken for capacity shortfall.
