The Miller Coolmate 4 is the best performer in its class, this industrial 4-gallon cooler is designed for water-cooled torches rated up to 600 amps.

•Weighs only 38 pounds (17 kg) dry
•Tough one-piece case is portable and rustproof
•Convenient carrying handle and filler spout are molded into case
•Easily accessible coolant filter
•Factory-set pressure-relief valve (60 psi) maintains consistent pressure during operation
•Thermally protected 1/4 hp motor guards against overheating
•Efficient fin-and-tube heat exchanger
•Coolant system has a constant flow of coolant inside to keep the pump primed and to reduce algae buildup in the tank
•Brass-body positive-displacement rotary vane pump provides consistent coolant flow and pressure rating with long pump-life expectancy

Closed-loop design with radiator reduces coolant temperatures and prevents the system from overheating. Closed-loop design also recirculates the coolant through a fan-cooled heat exchanger.

Rustproof coolant reservoir molded of poly ethylene for durability and corrosion resistance.

Standard inlet/outlet torch fittings are compatible with TIG and MIG torches having standard 5/8-inch 18 left-hand fittings.

10-foot (3 m) power cords are longer than most power cords in the industry — providing the extra length when required.

Compatible with Miller coolants and are ideal for warm and cold weather conditions, while providing HF or corrosion protection.
