300972 - Miller Coolmate 1.3 Water Cooler System 115V

Reliable Thermal Management for Welding Operations

The Miller Coolmate 1.3 is a dedicated coolant circulation system engineered to manage the thermal loads of water-cooled TIG and MIG torches in light-duty industrial environments. Designed with a focus on reliability and compactness, this unit integrates seamlessly with Miller's range of power sources, including the Dynasty, Maxstar, and Syncrowave series. The system utilizes a positive displacement vane pump, which is industry-renowned for providing consistent flow rates and pressure, ensuring that the cooling fluid effectively dissipates heat from the torch head and power cable.

Constructed with a polyethylene-molded coolant tank and shroud, the Coolmate 1.3 is inherently rust-proof and resistant to impact, making it suitable for shop environments where durability is paramount. The 1.3-gallon (4.9 L) reservoir is sized to provide adequate thermal mass for intermittent to continuous welding tasks without the bulk of larger industrial coolers. The unit features a high-efficiency fin-and-tube heat exchanger that delivers a cooling capacity of 3,400 BTU/hr at a flow rate of 1 quart per minute, maintaining optimal operating temperatures for torches rated up to 280 amps.

Operational safety and equipment protection are built into the design. A factory-set pressure relief valve limits the output to 60 PSI, preventing damage to torch hoses and internal components caused by over-pressurization. Additionally, the motor is equipped with thermal overload protection, and an inlet filter screens out particulate matter to protect the pump mechanism. The Coolmate 1.3 operates on standard 115V input power, making it a versatile addition to any welding station requiring efficient liquid cooling.
