Johnson Controls has introduced the Hitachi SET FREE Σ VRFs HVAC solutions to the local market. The SET FREE Σ VRF range is modern, intelligent, plug-and-play HVAC solution.

This is the eighth generation of Hitachi’s VRF solution and the first to combine Johnson Controls’ technologies, which includes connectivity to building management systems for greater intelligence, control and cost efficiency. The SET FREE Σ VRF boasts design flexibility, the highest efficiency in its class, and the range’s small footprint, which makes it easy to install, move and maintain.

“This range of Japanese HVAC solutions has a reputation for solid engineering and reliability—and with the addition of Johnson Controls’ advanced HVAC control and management capabilities, it’s a very welcomed addition to the solutions available in South Africa,” says Johnson Controls’ Neil Cameron.

Johnson Controls introduces new Hitachi HVAC solutions“The SET FREE Σ VRF meets many of the HVAC cost, feature, flexibility and reliability challenges currently facing South African users looking for mid-market solutions. These are important factors in the local market where energy costs are higher, and the slow economy is compelling users to add greater weighting to lifecycle costs.”

The SET FREE Σ VRF range is modular and can supply from 8 to 96HP, delivering 22-272kW of cooling and 25-300kW of heating. It achieves the highest COP rating (4.90) in its class, and has the smallest footprint per KW of heating – modules can be transported in an elevator and by pallet jack.

BMS connectivity allows for individual billing and better control of performance.

 “I believe this product is well positioned to meet local requirements. It is tried and tested and well established worldwide as a top end, reliable solution. With broader representation in the market and a strong support base, we believe the Hitachi SET FREE Σ VRF range will find a ready market in South Africa,” Cameron says.

“Our stockholding of key components has increased nationally, and supply chain turnaround times have increased dramatically to 24 hours. We have also invested in building technology support centres. One has already been constructed in Johannesburg and two more will be built in Cape Town and Durban in the next two years. We are, furthermore, providing HVAC solution providers with hands-on training on solution development, configuration, installation and fault-finding. Approximately 80 people have already completed this training.”
