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.

Eco ULTRA’s Humidity Intelligence – Adaptive software takes into account the time and building occupancy while measuring the temperature and humidity both indoor and outdoor, before making adjustments to ensure it maintains the desired comfort levels while operating efficiently. In a nutshell, it understands consumers’ needs and reacts instantly to current conditions to meet them. It also has the ability to follow patterns, which allows the Eco ULTRA to choose setting options that correspond to certain weather-heat load combinations.

MINIMISING REHEAT - While conventional systems consume large amounts of energy in order to meet de-humidification targets (often through a constant cycle of over-cooling and over-heating), the Eco ULTRA performs the task efficiently and inexpensively. The result is tightly controlled humidity, lighter latent loads and improved overall efficiency all year round and in all conditions.

COMFORT - As the system load varies, the unit adjusts automatically by changing speed as well as reducing the number of modules in use. The Eco ULTRA is based on a 100% modular design featuring four independent systems (compressors, evaporator and condenser fans) – all operating independently of one another.

While traditional on-off system stop and start as the load changes, producing less smooth control of temperature and humidity, the OPA 2100 ECO Ultra maintains comfort smoothly.

REDUNDANCY & MODULARITY While conventional air conditioning systems are typically optimised for full-load operation (thereby maximising energy consumption) Eco ULTRA’s outstanding performance at partload operation enables significant energy savings.

SEASONAL EFFICIENCY Eco ULTRA’s variable speed compressor ensures your HVAC system runs efficiently at all load levels. The result is high EER and extremely high SEER (a measurement of efficiency at variable work loads). Our leading variable speed technology ensures the unit perfectly matches the load required.

ENERGY MINIMISATION – With the reduced starting current and ultra part load efficiency, this unit is so smart that it can immediately understand everything it needs to in order to operate safely and efficiently.

An example of this is as the system load varies, variable speed compressors adjust the cooling capacity automatically by changing speed. At higher speeds more cooling capacity is provided, and at lower speeds the capacity is reduced.

ADAPTIVE CONTROLS Incorporated Adaptive technology ensures that Eco ULTRA is flexible, versatile and extremely user-friendly. One Platform – One controller. There are also multiple handling options are available to suit most applications.

Designed exclusively using Temperzone’s in-house R&D expertise, the Eco ULTRA represents a cutting-edge technology that strives to change the way sustainable air conditioning solutions are delivered.

The OPA 2100 ECO Ultra features an operational capacity of 200kW, that can operate at any capacity from 15kW, enabling it to easily react to changing building heat loads. This makes it ideal for use in a wide range of temperature and humidity-sensitive commercial spaces such as: Supermarkets, Shopping Centres, Labs, Food Processing or Manufacturing Plants, Industrial Facilities, Museums, Pubs and Clubs, Data Centres, Schools and Universities.

The Eco ULTRA is highly flexible with a range of benefits to suit a everyone from Consulting and Specifying Engineers to Contractors, Installers and Service as well as the end user.

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.

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.


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.


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

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!
