Plate Heat Exchangers

Alfa Laval TL3 Plate Heat Exchanger

 The faster milk is cooled after milking, the better its quality when it is collected from the farm.

Plate heat exchangers are one option for milk cooling.

Coolsense stocks only high quality Alfa Laval PHEs, suitable for all New Zealand dairy farms.

CoolCARE is another new product developed by Coolsense. 

A subscription-based support and telemetry service,  CoolCARE allows the user and the supplier to connect to chilling systems manufactured by Coolsense via a web browser or mobile phone, and monitor their performance in real-time. 

The hardware is provided in the chilling system and the data connection is controlled by Coolsense.

we're the big little company

Coolsense NZ Ltd is an innovative 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.
