Eco-Conscious Products

Efforts to decarbonise process heat have encouraged manufacturers to research and develop safe, reliable and efficient heating equipment that can not only deliver increased process heat but save your organisation money while reducing emissions. Our trusted partner brands have a variety of electric and biomass options including optimising equipment to monitor and control your current equipment.

Eco-Conscious Products for Process Heating

In May 2022 the New Zealand Government announced an emissions reduction plan to limit global temperature rise to 1.5⁰C above pre-industrial levels. The first goal for Aotearoa is to reduce emissions by 11.5 megatonnes of carbon dioxide by 2025. Government will support businesses to improve sustainability through the Energy Efficiency & Conversation Authority funding and support. Our management and staff will keep you informed of funding options as they become available and are here to assist you with product information during the proposal process.
