Commercial & Industrial Heat Pumps
The success of the SIRAC Heat pump is a direct result of our vast experience, observations, field testing and close collaboration with the design engineers that have taken place since our first installations in 2007. Our heat pumps have been specifically designed to accommodate the requests from installers and engineers and the wide temperature and altitude conditions experienced in Africa.
The SIRAC comprehensive heat pump range provides outstanding performance and efficiency over a wide spectrum of operating conditions and applications.
60°C Heat Pumps
SIRAC Heat Pumps are all supplied with an easy to operate, factory wired remote microprocessor control system providing diagnostic control of the unit and RS485 Modbus connectivity. The electronic expansion valves maintain precise refrigerant metering and are controlled by the microprocessor.
The compressors have been selected for their exceptional reliability and performance. All necessary refrigeration safety controls, a remote on/off switch and a circulating pump contactor are controlled by the microprocessor.
The unit has a purpose manufactured tube in tube heat exchanger that provides excellent efficiency and reduces tube fouling. Spacious compressor and electrical compartments provide easy access for servicing and maintenance.
- Attractive, well-engineered product.
- Strong local support and service back up.
- ISO 9000 Manufacturing facility.
- Modbus Connectivity via RS485 port. Offering read/ write connectivity, remote access and diagnostic information.
- Simple uncomplicated design.
- Three-year compressor warranty.
- Large Spacious easy service access.
- Sturdy steel base that provides rigidity to the frame structure.
- Heavy gauge galvanized steel panels and frame, epoxy painted after manufacture. An option for 304 Stainless Steel is available for coastal installations.
- V–design evaporator coil with coil guards are available for larger models. This configuration reduces the chance of hail damage to the coil face.
- Designed to meet with European energy standards. The evaporator coils are designed to operate down to -20°C ambient temperatures. This makes the unit extremely efficient when operated in the African mild climate

The unit has a purpose manufactured tube in tube heat exchanger that provides excellent efficiency and reduces tube fouling. Spacious compressor and electrical compartments provide easy access for servicing and maintenance.
When operating at 65°C water, the SIRAC Scroll Compressor operates in a very safe, stable and efficient part of the operating envelope. This results in an exceptionally high COP and reliability.
- Break-through heat pump technology enables the SIRAC High-temperature heat pumps to maintain water temperatures up to 80°C.
- This product is ideal for Health Sector & Process Plant Applications such as abattoirs, dairies, laundries, drying facilities, chemical plants and food processing plants.
- Environmentally friendly R134a refrigerant has been chosen to maximise the efficiency and reliability of the heat pump.
- The compressor has exceptional discharge temperature management and together with other proprietary features, it allows the operation envelope to be reliably stretched well beyond that of traditional medium-temperature heat pump units.
- The ability to heat water well beyond the typical 60°C range makes this product suitable for the prevention and control of Legionella.
