Leading companies in the heating, energy, refrigeration, ventilation and air conditioning (HERVAC) industry are a force for change in moving the industry from being energy-intensive to energy-intelligent. This is Part 2 of a two-part series.

In the supermarket, convenience store and other food retail markets, refrigeration is essential to preserve perishable goods and ensure compliance with health and safety regulations.
In addition to the importance of refrigeration, other HERVAC systems also play important roles in protecting products and equipment in the retail spaces. Poor ventilation and inconsistent temperature controls can damage sensitive products such as pharmaceuticals or electronic equipment; and unmanaged humidity and temperature controls can cause health risks from mould or damp in the retail space.
Climetal S.L., a European specialist in microchannel heat exchangers for the HERVAC sector, will mark its entrance into the Southern African market at FRIGAIR 2025. From compact rooftop units to large-scale chillers, Climetal’s solutions are engineered to deliver high performance, energy efficiency, and reduced refrigerant charge. The company aims to support local equipment manufacturers and system integrators with tailor-made components that combine European engineering precision with application-specific flexibility in thermal solutions.
Low global warming potential (GWP) refrigerants
New advances in the HERVAC industry are enabling retailers to adopt more sustainable energy efficient technologies. Integrations in solar and geothermal energy into HERVAC systems, the use of low GWP refrigerants and the use of new smart demand-based HERVAC control systems are enabling retailers to achieve sustainability goals as well as comply with building codes, environmental regulations and safety standards.
Europe is already phasing out refrigerant R32 and using R290 and R1234ze which are more eco-friendly refrigerants. Known for its exceptionally low environmental impact, despite its flammability R290 is ozone friendly with a global warming potential of 3 and ozone depletion potential of 0. Local exhibitor AERSA will exhibit its PRG0332XHDEJ02 unit model at FRIGAIR, which features R290 as its refrigerant as a greener refrigerant option. The unit delivers a powerful 70kW of both cooling and heating capacity and can generate hot water temperatures up to 75°C, offering a robust solution for large-scale, eco-friendly heating and cooling needs.
Staycold International, based in the Free State, will also exhibit new technology advancements manufactured with R290 gas at FRIGAIR 2025. Staycold’s hydrocarbon freezer technology will be on display with a new single door full height freezer. This is an extension to their range, utilising hydrocarbon R290 gas, a natural refrigerant with a low Global Warming Potential (GWP) index. All Staycold’s new coolers are manufactured with R290 gas and are expanding its use into their freezer range that meet the performance requirements of their units.
FRIGAIR 2025 is the ideal environment to discover the latest innovations, advanced technologies and future- ready solutions for all those looking for the best in heating, ventilation, air conditioning, refrigeration, and energy products and services.
FRIGAIR is organised by IMD Conferences, Exhibitions and Workshops in partnership with Specialised Exhibitions – a division of Montgomery Group.
