Our Products

Subscription-based support and telemetry, CoolCARE allows the user and the supplier to connect to each of the chilling systems manufactured by Coolsense.  The hardware is provided in the chilling system and connection is controlled by Coolsense.

why insulate your vat?

Wind, sun, high ground water temperatures, rain and summer temperatures can all cause your milk vat to gain heat. This means your refrigeration system is working harder than it needs to and may struggle to help you meet chilling speed and temperature          regulations.

Insulating your milk vat protects it from heat gain and reduces the load on your refrigeration system, delivering up to 20% additional refrigeration capacity. This chills your milk faster, using up to 40% less energy for refrigeration.

Our vat wraps come with a 5 Year Warranty, are easy to clean and are specifically made for milk vats using 10mm woollen blend fabric, sandwiched between two layers of 630/m2 high quality, hot air welded PVC. Contact us today to discuss your vat wrap needs.

we're the big little company

Coolsense NZ Ltd is a Hamilton based Refrigeration Equipment Specialist company. 

Formed in 2013, Coolsense specialises in packaged turn key chilling systems. 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 and R454b refrigerant driven gaseous refrigeration systems, closely focusing on water and glycol as its heat transfer method to reduce the refrigerant charge of its packaged systems.

Coolsense is also a specialist supplier of auxiliary equipment for the refrigeration industry focusing on heat transfer, fluid transfer and data acquisition through its proprietary ‘CoolCARE’ smart IOT (Internet of Things) telemetry system.
