Extend the lives of welding tips and electrodes by keeping them cool. Eliminate sticking and increase weld consistency with closed-loop chilling and cooling systems from MTA, available in simple systems for single-machine applications or larger systems for multi-machine operations.
Need a chiller now? Many standard units and configurations are in stock and ready to ship. Use the contact form to the right for more information.
Chillers have a refrigerant to keep temperatures manageable, while coolers recirculate and passively cool water. Chillers are better than coolers for higher-volume applications or higher-temperature systems such as aluminum welding. Maintaining electrode temperature can extend the life of your consumables and result in more consistent welds.
Standard Features of MTA Chillers
High-Efficiency Coil Evaporator Saves cooling energy costs throughout the life of the chiller. Uses copper tubes and aluminum fins inside tank to reduce ambient heat gain; process fluid flows in contact with finned surface, cooled by refrigerant
Dynamic Setpoint Capability Ability to link chiller output to the ambient temperature to avoid catastrophic damage from condensation
Non-Ferrous Water Circuit Copper and stainless steel components (water tank, pump, exchanger) resist corrosion
Indoor/Outdoor Capabilities Standard features include powder-coated steel case with IP44 to IP54 protection against dust and water; extreme hot/cold weather adaptations optional
Hermetic Scroll Compressors Orbiting scrolls, mounted on anti-vibration dampers with protection against
overheating, excessive currents and high exhaust temperatures
R410A Refrigerant High-efficiency, bromine- and chlorine-free; zero ozone depletion potential
Close Side Clearance Top exhaust design allows MTA chillers to sit close to other machinery, saving valuable floor space

Issues caused by insufficient cooling (From the WeldHelp Resistance Welding Troubleshooting Guide):
- Cracks & holes
- Inconsistent weld quality
- Sticking/stuck tips
- Stuck welds
- Undersized welds
- Excessively high component temperatures (indicated by accelerated discoloration)
- Excessive tip wear
