Temperzone - Leading the Way in R32 Commercial Products

There is a significant shift taking place in the Air Conditioning market and local manufacturer, Temperzone, is leading the way. In commercial air conditioning, Temperzone has led the innovation towards more environmentally friendly refrigerants, firstly from R22 to R410A, and now from R410A to R32. The shift to R32 provides lower Global Warming Potential and higher efficiency.

Switching refrigerants is no small undertaking and requires comprehensive in-house Research and Development, advanced testing capabilities, and specialised R32 holding and charging facilities. Temperzone’s motto, “Climate Innovations”, is the driving force behind the adaption of low GWP R32 refrigerant and the development of best-in-class solutions.

Temperzone currently offers the most comprehensive range of R32 commercial product available in Australia and New Zealand. Not only this, but they are also the only company to manufacture all their commercial products locally with manufacturing plants in Auckland and Sydney.

Temperzone is determined to become Australasia's first producer of a complete range of R32 commercial products”. A goal well on the way to being achieved since the launch of locally manufactured R32 products in Australia and New Zealand.

Temperzone have already released R32 Commercial Products such as;

  • R32 Econex Inverter light commercial split ducted range from 14.8kW to 35.1kW
  • R32 Econex Inverter vertical water-cooled package 9kW system
  • 200kW air cooled package unit, the OPA2100 (AIRAH product of the year 2020) R32 option with various projects completed.

Due for release late 2021 is the new Econex R32 air cooled inverter rooftop package range, up to 55kW. 

Over the past 12 months, a range of special R32 products have been produced, and are available, for  commercial projects in Australia and New Zealand. These include R32 versions of various inverter air-cooled package units and inverter hot water heat pumps.

Why the change to R32?

Temperzone is dedicated to innovating solutions to reduce the environmental impact of air conditioning. Global warming and the move towards energy efficient solutions drive the ongoing search for more energy efficient, environmentally friendly, safe refrigerant gases. R32 refrigerant delivers the dual benefit of reduced Global Warming Potential and increased efficiency.

Global Warming Potential (GWP) is a measurement used to compare the global warming impacts of different gases. GWP is represented as the ratio comparing how much energy the emissions of 1 ton of a particular gas will absorb compared to 1 ton of carbon dioxide (CO2). The larger the number, the higher the global warming potential compared to CO2.

While R32 is not new to the market, its availability has been limited to smaller capacity systems mainly used for residential applications. R32 has a GWP (675) which is less than a third of the currently used refrigerant R410A (GWP of 2,088). This reduction in GWP is the key reason Temperzone is innovating towards R32.

Another advantage of R32, when designed into an air conditioning system, is it improves efficiency by around 12%. R32 offers a lower GWP solution while also helping businesses to reduce overall energy usage.

Other Benefits of R32

  1. Zero ozone depleting potential (ODP)
  2. Offers higher efficiency and longer pipe runs
  3. Is F-Gas phasedown compliant
  4. Requires less refrigerant volume per kW
  5. Is readily available
  6. Is a single component refrigerant, i.e. easier to reuse and to recycle.

Temperzone’s offering of R32 across all commercial refrigerant systems will provide a 75 - 80% reduction in GWP per kW of cooling or heating and assist in pathing the way for a zero-carbon future. As these changes in technologies occur within the air conditioning industry, Temperzone’s design approach is to ensure the continued reliability, ease of application and serviceability of our systems.


Why Mines Choose Temperzone

We have designed manufactured and supported air conditioning equipment for use in some of the harshest environments on the planet. The Woodside Energy Pluto LNG processing plant is an excellent example of how Temperzone works closely with the mining sector.

Econex = Efficiency, Control and Sustainability.

Econex is the superior choice for delivering energy efficiency, reduced operational costs, lower total cost of ownership, a superior capacity range for increased comfort, and a more sustainable refrigerant. 

Two Iconic Brands, One Ideal Solution

Temperzone Split Ducted and Hitachi VRF deliver the perfect solution for Bundaberg Motor Group's new purpose-built premises, that houses 9 new car brands plus used cars and a service and parts centre, all located in the centre of Bundaberg.

A great example of the flexibility and customisation Temperzone is willing to undertake for clients to ensure we fit the specification.

Temperzone’s R32 Commercial Products Making Inroads in New Zealand

New World, a supermarket chain under Foodstuffs Co-operatives in New Zealand, recently opened a new store in Hobsonville, a rural suburb of Auckland. New World is committed to sustainability and doing their part to reduce their operational carbon emissions. The stores are 100% New Zealand owned and operated and have a very strong focus on local products. So, it is fitting that the OPA 2100 unit that was installed not only uses R32 refrigerant but was also the first of its model to be made in the Auckland factory. The system was installed by McAlpine Hussmann.

The Multi-Award Winning Temperzone OPA2100 Eco Ultra is now the AIRAH 2020 Product of the Year

Temperzone’s OPA2100 Eco Ultra recently won the prestigious 2020 AIRAH “Product of the Year” Award. The award recognises excellence in product manufacture, with products assessed on their innovation, energy efficiency, sustainability, originality and industry need.


Temperzone has started releasing its next generation R32 – Inverter compressor product under the Econex brand.

Just as Temperzone led the industry with the adoption of R410a in commercial air conditioning systems, we are again leading with R32.

Warriewood Cinema - A Slightly Unusual Solution

The Warriewood Cinemas replacement project in April 2020 had some slightly unusual application issues. A little lateral thinking, a great product range and the ability to manufacture locally in the middle of a pandemic, produced a successful solution.

OPA ECO Series

Temperzone’s ECO Series of Rooftop Package Units continues to evolve as some of the most energy efficient air conditioning units in the market. With unit capacities ranging from 11.6kW to 193kW Temperzone Eco Rooftop Package Units are used in a huge range of applications from shopping centres to food manufacturing plants to pubs and clubs, schools and office buildings.
