Liquid Cooling Technology

Personal cooling systems were first developed more than 60 years ago to regulate the body temperature of astronauts and military pilots during their intense and heat-stressing duties.  More commonly referred to as a liquid personal cooling system, it included a cold sink (e.g.: ice or refrigerant), a fluid pump and power unit connected via hoses to a tubing-lined garment.  In operation, the system’s pump circulated cooled fluid in a continuous loop between the garment and the cold sink to regulate the user’s body temperature, thus allowing them to work safely and comfortably for longer periods of time.

For the past 15 years, Compcooler has expanded this technology to offer several kinds of liquid personal cooling systems that cater to a myriad of workplace applications.  These systems are grouped into two main categories: self-contained or tethered.

Self-contained systems are designed for applications where the user requires freedom of movement, and as such, these systems are battery powered and carried on the person.    Conversely, tethered systems are designed for stationary applications.  The cooling system is separated from the User’s cooling garment and connected with long coolant tubes.  Tethered systems are typically powered by unlimited energy sources such as an AC outlet or a vehicle’s DC battery. 

Compcooler’s garments are suitable for nearly all of its cooling systems.  The standard vest is a highly engineered breathable mesh garment that weighs a mere 0.5KG (1.1 lbs.), dry weight.  It consists of a soft mesh outer fabric, and inner liner which is easy to don and comfortable to wear against the body.  A zipper and adjustable tabs provide a snug fit for maximum thermal transfer.
