Two Iconic Brands, One Ideal Solution

Bundaberg Motor Group is the biggest multi-franchise dealership in the Wide Bay - Burnett region with a purpose-built premises that houses 9 new car brands, used cars and a service and parts centre, all located in the centre of Bundaberg.

With a facility of this size, their air conditioning needs were unique and varied. Temperzone Queensland worked closely with Toowoomba based mechanical contractor NRG Services and consultant Diametric Engineers to select the best equipment based on the building design and performance specifications.

The base build design required six Temperzone reverse cycle ducted split systems, ranging from 21kw to 57kW for the main showrooms and a Hitachi VRF system for the offices, service, and finance departments. The Temperzone ISD/OSA 211 as well as the ISD/OSA351 ducted systems used on the project are R32 Inverter systems. First to introduce low GWP R32 refrigerant into systems of this type and capacity allows us to reduce associated GHG emissions by between 75-80% per kW of heating or cooling as well as delivering exceptional part load performance. Temperzone is set to continue its release of new R32 inverter commercial products this year as part of our commitment to the be the first commercial local manufacturer with a complete range of R32 products.

The Hitachi VRF systems is a modular 73kW with 15 x 4-way cassettes and 1 ducted system. Advanced PC-ARF local controls were used throughout the system and in each office, ensuring the staff can control the comfort levels throughout the entire complex.

The Bundaberg Motors project is an excellent example of how Temperzone consistently delivers exceptional air conditioning solutions with a combination of both Temperzone and Hitachi equipment for commercial and light commercial applications. Our partners in design and installation ensured the completion of our successful project package.

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.
