Introducing Econex – Temperzone’s Next Generation R32 Plus Inverter Products

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

R32 Refrigerant

Inverter Compressor


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

New Econex Light Commercial Split Ducted range

The first Econex product group to be released are light commercial split ducted systems. These innovative units have nominal cooling capacities from 14.8kW to 35.1kW. All these Econex split ducted systems have inverter compressors and R32 refrigerant.

The use of R32 refrigerant, combined with a lower unit refrigerant charge, allows Temperzone to reduce the GWP (Global Warming Potential) by between 75-80%. System efficiency is also increased by utilising the improved thermodynamic properties of R32 along with advanced inverter control.

By using the full capability of inverter compressor technology, these units have been designed with an extended range of heating and cooling capacity. Cooling capacities can be boosted between 23% and 30% above nominal capacity. Heating capacities can be boosted between 16% to 25% above rated. Extended capacity range allows much more flexibility in specification.

Econex Inverter compressors have increased economy through seasonal part load savings. A 1:6 turndown ratio across the range allows these units to efficiently meet the widest range in seasonal fluctuations of load demand. Key to this part load efficiency is coil design. A revolutionary new coil design allows the refrigerant system to operate reliably across the full compressor speed range and ambient conditions.

The new coil design also supports a new intelligent de-ice function. Smarter de-icing enables a significant improvement in heating performance in colder conditions. The new coil design allows a doubling of the interval between de-ice cycles. When the need occurs, the actual de-ice process is faster and more effective.

A new removable corner access panel for electrical access makes wiring access easy and convenient. The access panel allows mains power supply and communication connections to be wired directly without internally accessing the unit.

As with other Temperzone air cooled systems, Econex R32 Inverter units have been designed for the harshest conditions to provide heating at -15C ambient and cooling at +52C ambient.

Temperzone’s intelligent unit controller enables BMS connectivity and advanced independent zone temperature control for multiple spaces.

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.

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

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.

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.


Temperzone’s OPA2100 ECO ULTRA has been awarded the CIBSE Highly Commended award for the Product or Innovation of the Year - Thermal Comfort category. The Chartered Institution of Building Services Engineers (CIBSE) Building Performance Awards recognise the people, products and projects that demonstrate engineering excellence in the built environment. The awards are open to organisations, both in the UK and internationally

Temperzone Australia Environmental Policy

Temperzone takes its responsibilities as a member of the corporate community very seriously. This Environmental Policy isn’t just a collection of impressive statements, it is fundamental to the way we do business.

Hermitage Agr. Research Station - QLD

The best way to describe this unusual project is 'Super flexible and controllable'. Temperzone OPA-ECO units meet very clever Modbus programming and solves an almost impossible air conditioning problem. And, oh yes, fit the budget too!


In January this year the “Energy Rating” organisation announced that from April 2019 a standardised method of calculating the Seasonal Energy Efficiency Ratio (SEER) will come into play.

Introducing the New OPA 2100 ECO Ultra Rooftop Package Unit

The new OPA 2100 ECO Ultra rooftop package unit is the flagship of Temperzone’s new ECO Ultra range. It’s a 200 kW rooftop package unit with 4 inverter compressors plus a patented humidity control system that makes this unit absolutely unique. Eco ULTRA is a revolutionary climate control solution for spaces where temperature and humidity regulation is critical.
