Coolsense NZ Ltd is a Hamilton based Refrigeration and Thermal Energy Storage Systems (TESS) manufacturing company. Formed in February 2013, Coolsense specialises in the on-farm and agri-tech markets, primarily supplying chilling equipment to the dairy farm market. It is a dedicated lean manufacturing company and has been built from the ground up using systems that fully support an Original Equipment Manufacturing operation. Its initial development of a variable capacity packaged chilled water system has built Coolsense a reputation as a manufacturer of high quality, highly efficient R410a refrigerant driven gaseous refrigeration systems, closely focusing on water and glycol as its heat transfer method.



Technical Director

A true-blue Scottish born and bred fella is the Technical Director and developer of the Vari-COOL technology. Allan emigrated to New Zealand in 2001 as a Biopharmaceutical Process Engineer initially working for PPL Therapeutics (a subsidiary of the Roslin Institute) where he headed up the technical services department engineering equipment to extract the protein from transgenic ewes.

In 2004 Allan was third party contracted to Fonterra to collate data on snap chilling milk. This research led to his development, in 2005, of his first Thermal Storage system which (through his company New Zealand Cold Ltd) went on to gain a Technical Appraisal Project grant from Technology New Zealand.

In 2006, the final concept resulted in a chilling system named the Aqua-TESS which was launched onto the market in 2007 with 30 reference sites established. In 2009 Milfos purchased the technology and this unit is now known as the i-Converter. Allan’s technology was launched into the Australian, Britain and the Fonterra China mega-farm markets and he was responsible for many of those installations.

In 2013 the opportunity presented itself to redevelop a new chiller system using technology advancements in the refrigeration industry and this formed the basis of incorporating Coolsense NZ Ltd and the establishment of the Vari-COOL system. Allan recalls he had “been working with chilling systems and compromising on getting the exact product I wanted since I started in the industry in 2005. Now we can concentrate on building something that the Coolsense team and I can be really proud of”.

Allan is married with four daughters and when he’s not developing state of the art refrigeration systems he rides very fast motorbikes.
