All Black Rooftop Units for Tauranga’s Thirty Eight Elizabeth Project

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

Tauranga’s Thirty Eight Elizabeth, a $200 million construction project, is currently the largest development of its kind in New Zealand outside of Auckland. It includes 8,000sq metres of retail on two levels, 97 high-end apartments across 10 storeys and two towers, and 23 luxury townhouses. The prestigious shopping complex centres around a flagship Farmers Ltd double level retail store. The development is set to revitalise Tauranga’s heart of the city by bringing an exciting new community of exceptional living, shopping and dining together in an architecturally designed environment.

Tauranga, with a population of 150,000, is a harbourside city in the Bay of Plenty region in the North Island of New Zealand. The Port of Tauranga is New Zealand's largest port in terms of gross export tonnage and efficiency. Tauranga is located around a large harbour and is therefore subject to significant sea spray across the coastal regions.

Temperzone’s customer, Tempest Ltd, was selected by the developer and BECA consultancy to supply the air conditioning units on a design/build contract. Tempest has a long-standing relationship with Temperzone and has used the custom adaptable Thermal Cube PA series of roof top packaged AC units extensively for more than 15 years.

In this development, Temperzone's sales executive negotiated with Tempest Ltd and was supported Custom Engineering to successfully acquire the order for 4 unique PA3600 Rooftop Packaged Air Conditioning units in the Thermal Cube PA range. The PA3600 delivers 115kW of cooling capacity with 6000 l/sec via 3 compressors where one is variable capacity, high efficiency EC plug fans, electronic expansion valves with pressure transducer refrigeration system control through Temperzone’s proprietary UC8 system controller.

As the units will be on a lower plant platform than the residential apartments, the architect wished to disguise the equipment by utilising a dark horizontal elevated louvre system above the vertical discharge rooftop AC units. Thus, the customisation of the units was to be powder coated Matt Gravel to not stand out under the louvres.

They also required high static outdoor fans to cope with the increased static pressure of the louvres. The base, main walls and drain tray were all to be stainless steel. Not only is the conditioned air stream of the PA unit acoustically lagged, the compartment with the 3 compressors is also insulated with acoustic insulation. As part of the service, Temperzone fitted the controls package received from Tempest Ltd into the unit during construction.


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.

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 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.
