Sirac Heat Pump Regassing in Isando
Sirac heat pump regassing in Isando. 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.
Warehousing, cold chain and light manufacturing with process hot water and boilers. Cold chain and process plant scheduled around production. Gauteng municipal water is moderately hard, so scale on elements and heat exchangers is the single most common cause of falling performance.

FAQs
Frequently asked questions
Are you an authorised Sirac agent?
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 heat pump regassing include?
Nitrogen pressure test and vacuum hold test, Electronic and UV dye leak tracing, Braze repairs to pipework, joints and coils, plus verification that the unit performs to the manufacturer's stated figures after the repair.
Do you service Sirac units in Isando?
Yes. Isando is inside our service area. Ekurhuleni call-outs are grouped by area so industrial and commercial visits can be attended on the same run.
Is it worth repairing an older Sirac unit?
We give a repair-versus-replace figure with the quotation so the decision is based on cost, not on guesswork. Modular banks where lead/lag sequencing faults are frequently mistaken for capacity shortfall.
