Compcooler

Compcooler Backpack ICE Water Cooling System 3.0L Green

SKU CH-ATEH-AAN94

A portable 3.0 L ice-water system circulates 36–68 °F coolant through a zippered vest for 2–4 hours of core-temperature relief

  • Portable self-contained cooling with 3.0L bladder and 7.4V battery
  • Cools core temperature using 36F-68F water circulated to four vest zones
  • Provides 2-4 hours cooling per frozen bladder fill
  • Adjustable zippered vest with Velcro tabs ensures maximum thermal transfer
  • Expandable runtime with extra bladders and batteries for longer shifts

Portable personal cooling system

The Compcooler Backpack ICE system delivers self-contained liquid cooling for workers who need mobility in hot environments. A 3.0-litre detachable bladder, rechargeable 7.4 V battery and miniature pump fit inside a backpack that circulates chilled water to a tubing-lined vest. The garment uses Velcro adjustment tabs for a snug fit against the skin, enabling four-zone thermal transfer while the user moves freely.

Sustained cooling performance

Frozen water in the bladder provides a cold energy source that circulates fluid at 2-20 °C (36-68 °F) for two to four hours per fill. The quick-connect fittings allow rapid bladder swaps so additional frozen reservoirs extend operating time without interrupting work. Because the system relies on stored ice rather than active refrigeration, output remains steady until the phase-change energy is exhausted, making it predictable for shift planning.

Upgrade from passive gear

This replaces evaporative vests, ice packs or stationary fans that restrict movement or lose effectiveness in high humidity. The jump is worth it when a task demands continuous core-temperature management for multiple hours while the wearer walks, climbs or operates equipment. Buyers who need all-day cooling without bladder changes or who require sub-ambient temperatures beyond the ice-phase range should consider supplemental bladders or alternative technologies.

Questions about this item

How long does the 3.0L frozen bladder keep the vest circulating 36F-68F water during a full shift?

The 3.0-liter bladder provides 2-4 hours of cooling once frozen; extra bladders can be swapped in for longer shifts.

What must I already have to start using the system right out of the box?

Everything needed is included — vest, backpack unit with pump, 3.0L bladder and 7.4V rechargeable battery — just add water and freeze the bladder.

Will the quick-connect fittings on this 3.0L bladder work with older Compcooler vests I already own?

The bladder uses quick-connect fittings designed for the included vest; compatibility with earlier models is not confirmed by the manufacturer.
