Products COOLING THE OLD LIKE NEW Cool Breeze has landed the latest technology in inverter motors as an optional extra on all new Cool Breeze coolers. Cool Breeze has always been known for superior airflow combined with high-efficiency motor technology providing excellent cooling capacity. Now Cool Breeze Maxima Inverter technology provides even further money savings on power usage. Combined with precise control and very low airspeeds allows for just a ‘whisper of air’ if required at very low power consumption – as little as 50W for the D255 cooler. Maxima Inverter kits are also available to retrofit to most existing Cool Breeze coolers providing an instant upgrade and new lease on life to older Cool Breeze systems. With Cool Breeze unlock the added advantages of lower running costs, greater comfort, superior airflow management and reduced noise levels. For more information, contact +27 (0) 11 887 8985. CONSIDER R-32 We have all heard about the Montreal Protocol and the phase-out of HCFCs like R22. Now the world is ready to phase out HFCs like R410a. This phase-down has become known as the Kigali Amendment to the Montreal Protocol. The amendment adds to the Montreal Protocol. South Africa signed this agreement in July 2019. Thus, there will be a phase-down on HFCs planned to start from 2024. Daikin has identified R-32 as a very beneficial refrigerant for single and multi-split type air conditioners and heat pumps based upon the above criteria. Daikin believes that the transition to R-32 will help to meet both the HFC phase-down schedule and the HCFC phase-out schedule. To mitigate future global climate change, it is important to take a ‘sooner the better’ approach. Early implementation is key to the further reduction of future impact.

COOLING ECONOMICALLY Stulz has upgraded the DX models of its proven CyberAir 3 DX series – delivering even greater efficiency savings and increased cooling capacity. Offering exceptional energy efficiency ratios (EER) and airflow efficiency ratios (AER), this enhanced range of precision cooling units ensures maximum reliability for mission critical applications, as well as achieving significant savings in energy and costs. Providing the energy-saving advantages of indirect free cooling, the Stulz GES hybrid systems are available with outputs in excess of 100kW. These new developments offer all output levels – from 30kW to 130kW and the provision of cooling systems with tandem compressors – capable of handling partial loads, potentially increasing further energy savings. In addition, as the supply air temperatures of the cooling systems lie within the recommended range of between 18°C and 27°C, they are fully ASHRAE-compliant. 80 RACA Journal I January 2020 For more information, contact +27 (0) 11 397 2104. www.hvacronline.co.za
