300245 - Miller Coolmate 3.5 CE Water Cooler 115V 50Hz

Industrial Cooling Performance for Heavy-Duty Welding

The Miller Coolmate 3.5 CE (SKU: 300245) is a high-performance water cooling system designed to manage the thermal loads of water-cooled TIG and MIG torches rated up to 600 amps. This specific model is engineered for 115V input power at 50 Hz, making it compliant with specific CE regional standards or industrial site power requirements where 50 Hz is the norm. The unit features a substantial 3.5-gallon (13.2 liter) reservoir, which provides ample thermal mass to maintain consistent coolant temperatures during extended welding cycles. With a maximum cooling capacity of 4,140 BTU/hr, the Coolmate 3.5 ensures that torch consumables and power cables remain within safe operating temperatures, preventing overheating and extending the lifespan of your equipment.

Structurally, the Coolmate 3.5 utilizes a rotomolded polyethylene tank, fan shroud, and filler spout. This material choice is critical for industrial environments as it renders the unit rustproof, thereby eliminating a common source of coolant contamination that can clog torch lines or damage pump impellers. The pump itself is an industrial-grade vane pump designed for continuous recirculation duties. The unit's physical architecture is a horizontal, low-profile form factor measuring 11.75 inches in height. This design is intentional, allowing the cooler to be stacked directly beneath Miller Dynasty 350/700 and Maxstar 350/700 power sources. This integration creates a unified, compact welding station that can be easily mounted onto a Miller Runner Cart, streamlining the workspace and reducing cable clutter.

Maintenance and operation are simplified through thoughtful engineering. The filler spout and filter are easily accessible, facilitating routine fluid checks and system cleaning without requiring extensive disassembly. The unit draws a maximum current of 4.7 A to 5.9 A depending on load, ensuring it operates efficiently within standard 115V circuit capacities. For fabrication shops requiring reliable thermal management for high-amperage welding on a 50 Hz power grid, the Coolmate 3.5 CE stands as the authoritative solution in the Miller lineup.
