235422 - Miller Coolmate 1.3 Replacement Coolant Reservoir

Restore Your Cooling System with the Miller 235422 Coolant Tank

The Miller 235422 Coolant Tank is a critical replacement component designed specifically for Miller's Coolmate 1.3 water cooling systems. These cooling units are frequently integrated into the popular Dynasty 210/280 and Maxstar 210/280 TIG runner packages. Over time, industrial environments can take a toll on plastic reservoirs. Exposure to UV light, accidental impact, or long-term chemical contact can lead to cracks, brittleness, or leaks. A compromised tank not only creates a mess in your workshop but also jeopardizes the efficiency of your entire cooling loop.

This genuine Miller OEM part ensures a perfect drop-in fit, eliminating the struggle associated with generic or makeshift reservoirs. Manufactured from high-quality, chemical-resistant polyethylene, the tank is built to withstand the rigors of daily welding operations. Its translucent design allows operators to quickly verify fluid levels at a glance, ensuring that the pump never runs dry—a scenario that can lead to costly pump failure or torch burnout.

Maintaining your water cooler is essential for high-amperage TIG and MIG welding. The coolant tank acts as the heart of the reservoir system, holding the heat-transfer fluid that keeps your torch cool. By replacing a damaged tank with the Miller 235422, you ensure that your system maintains the correct volume of coolant, providing consistent thermal management for your equipment. Whether you are repairing a leak or performing preventative maintenance on an older machine, this tank restores your equipment to factory specifications.

Trust in genuine Miller parts to maintain the reliability and longevity of your welding investment. This tank is designed to work seamlessly with Miller's standard low-conductivity coolants, ensuring chemical compatibility and long service life.
