Minus40 is an engineering consultancy specialized in refrigeration, thermal engineering and process cooling & heating.  The director and principal of Minus40, Michael Bellstedt, holds a PhD in thermal engineering and is an acknowledged expert in refrigeration and cooling/heating system design and troubleshooting, both nationally and internationally.  

Our highly qualified team of engineers is experienced in a range of industries and our internal methodologies have been developed and perfected over many years. Our project list is long and varied, and is available on request.  We conduct fundamental design, carbon footprint analysis, desk-top modeling and documentation, and also don our safety boots and get dirty on site to observe, monitor, troubleshoot and interact with operators.  

We work directly with end-users and contractors, but frequently subcontract our services to multi-disciplinary consulting firms when these require our specialist knowledge.  We can help you.
