Compcooler Univest Self-Contained ICE Water Circulation Cooling System Compcooler Univest ICE Water Circulation Cooling System for workers in hot ambient Model COMP-UICS-7430-NF. Just because it’s hot outside doesn’t mean you can’t work or enjoy your activities. With the Compcooler Univest Ice Water Cooling System you can work cooler, safer and stay focused for longer periods of time. This self-contained thermal regulation system combines a tubing-lined vest with an integral (permanently attached) backpack that houses the liquid cooling system. Available in sizes XS/S, M/L, XL/2XL, 3XL/4XL, the vest is a highly engineered Univest system that weighs a mere 1.0KG (2.2 lbs.), dry weight. It consists of a breathable and waterproof Nylon fabric and inner mesh liner which is easy to don and comfortable to wear against the body. The liquid cooling system is contained in an integral backpack includes a 2.5-liter removable water/ice bladder, miniature circulation pump, 7.4V 2200mAh rechargeable battery, and On/Off switch. When operating, it’s audible output is 45dBA. Cooling energy is provided by removing the bladder from the system, filling it with water and placing it in a freezer. Once frozen, the bladder is easily re-attached to the system, and with a charged battery pack, Users turn the switch ‘On’ and the pump circulates cold water in a continuous loop between the bladder and vest. Depending on ambient temperatures and workload, Users can expect a cooling duration anywhere from 2 to 4 hours with a fully frozen bladder or 1 to 3 hours using ice cubes in the bladder. The battery can last up to 10 hours. Additional bladders and battery packs can be purchased for prolonged cooling. Integral Liquid Circulation Cooling Unit and Tube-lined Cooling Vest Personal Thermal Regulation Technology, Liquid Cooling Garment Cooling energy is provided by freezing the water in the bladder. This is easily accomplished by removing the bladder from the system using quick-connect fittings, and then placing the bladder in a freezer. Once frozen, the bladder is easily re-attached to the system using the quick-connect fittings. With a charged battery pack, Users turn the switch on and the pump circulates cold water in a continuous loop between the bladder and vest. With the included 2.5-liter bladder, Users can expect a cooling duration anywhere from 2 to 4 hours depending on ambient temperatures and workload. Additional bladders and battery packs can be purchased for prolonged cooling. Benefit of Liquid Circulation Cooling System Univest Garment can expand 15% (Max 15cm/6”) by sides Velcro adjustment tabs, it also provides a snug fit for maximum thermal transfer. Liquid circulation cooling system is an active cooling solution. Mini pump circulates cold water from chiller or ICE bladder to cooling channels embedded on the cooling garment, and continuously flow around the body. BENEFITS OF LIQUID COOLING SYSTEM Reduction in body core temperature, increased duration. Reduction in skin temperature, decrease in hydration need Reduction in heart rate, improve mental acuity Reduction in sweat rate, maintain physical performance Cooling Vest Size 2.5L Detachable Bladder Model: COMP-SQB-15/25/50. The Cooling Bladder is designed with a single chamber that provides the User with the energy necessary for body cooling in the form of frozen water. Quick-connect inlet and outlet fittings on the bladder work in conjunction with the pump in the COMPCOOLER personal cooling systems. Choose between three capacities, 2.5 liter for use with COMPCOOLER Backpack and Univest personal cooling systems and 1.5 liter for use with Waistpack personal cooling system, 5.0 liter for dual chamber backpack personal cooling system. Rechargeable Battery and Charger 7.4V 2200mAh Model: COMP-RB-7422 The rechargeable Li-Ion battery is used to power COMPCOOLER Personal ICE Cooling Systems including Backpack, Waistpack, Univest and ICE Chest Cooling System. Each of these personal cooling systems incorporate a frozen (water) bladder and pump to produce flowing cooled water to a tubing-lined garment, pad or other device. This rechargeable battery is sized to efficiently power this type of system for 8 – 10 hours and includes a charger. Mini Circulation Water Pump 7.4V DC Model: COMP-WP-74FC-UV When operating, it’s audible output is 45dBA. Cooling energy is provided by removing the bladder from the system, filling it with water and placing it in a freezer. Once frozen, the bladder is easily re-attached to the system, and with a charged battery pack, Users turn the switch ‘On’ and the pump circulates cold water in a continuous loop between the bladder and vest. 3 settings for regulating coolant flow lets the User minimize or maximize their ice energy. Low flow produces less cooling and conserves ice. High flow produces more cooling for a shorter period.
