Water Vest Chillers

High-temperature workplaces are often the reality of many industries across Australia. High ambient temperatures and high humidity can lead to an increase in the body’s core temperature which can be detrimental to a person’s productivity, health and mental wellbeing.

  • Temperature and humidity can reach well above the level where the body can discard metabolically generated heat. Inability to discard generated heat leads to an increase in core temperature.
  • There is the potential for depleted mental capacity and heat stroke due to the rise in the body’s core temperature
  • Development of long-term effects in workers from heat stress

Water Cooled Vests are an amazing way to support the regulation of body temperature for people working in hot environments and can have a significant impact on wellbeing and performance in the workplace.


Our Water Vest Chiller units provide the recirculation of cool water to Water Cooled Vests, providing immediate temperature relief to personnel and improving their comfort.

Depending on the installation, our water cooled vest solution can support staff across wide distances from a central chiller hub. Our recirculation technology ensures that water is recirculated within the entire system rather than set up for one-time-use.

Water Vest Chillers
