Welding Chillers

Water Chillers for Welding Applications

Welding chillers circulate temperature-controlled fluid through welding equipment to remove heat during operation. In resistance welding, cooling water helps control temperatures in electrodes, transformers and other water-cooled components. Cold Shot Chillers offers air-cooled and water-cooled systems for industrial welding applications. Our team reviews your heat load, duty cycle, coolant temperature, flow and pressure requirements to help select a chiller for your equipment.

Cold Shot Welding Chillers Help Minimize Process Costs

Resistance welding generates heat in electrodes, transformers and other components. Consistent cooling helps control equipment temperatures during repeated weld cycles.

A closed-loop welding chiller recirculates cooling fluid instead of continuously drawing and discharging city water. This can reduce water and sewer costs while providing more consistent coolant temperatures.

Welding Chiller Configurations and Options

Cold Shot Chillers offers air-cooled chillers and water-cooled chillers for industrial process cooling. The right configuration depends on your welding equipment, installation space and available utilities.

When requesting a welding chiller, review these requirements with our team:

• Cooling capacity: Heat load and operating schedule for the connected equipment.
• Pump requirements: Required coolant flow and pressure.
• Reservoir configuration: Whether the application needs an internal tank or uses an existing external reservoir.
• Controls and protection: Temperature control, flow monitoring and alarm requirements.
• Installation conditions: Available voltage, ambient temperature and indoor or outdoor location.

Include the welding equipment’s cooling specifications with your quote request so our team can review the application.

Spot Welding Cooling Systems

As earlier stated, temperature regulation during spot welding is critical to the success of the process. Several methods can be used to adjust thermal conditions.

Cooling Via City Water Systems

While this method incurs very few costs at setup, continuous use will generate other costs from:

• Proper wastewater treatment
• Water usage
• Sewer usage

City water temperatures can vary, making consistent cooling harder to maintain. Condensation can also form when cooled surfaces fall below the surrounding air’s dew point. This risk applies to both city water and chilled water, so coolant temperature must account for equipment requirements and site humidity.

Recirculating Welding Water Coolers

Recirculating welding water coolers reuse coolant, reducing water consumption and discharge. Many compact units reject heat through a radiator and fan. Their suitability depends on the equipment’s heat load, required coolant temperature and ambient conditions.

Industrial Process Chillers

Industrial chillers used for seam welding operate like recirculating coolers as they use the same closed-loop setups. However, process cooling systems can be modified to handle industrial cooling on a larger scale. They often include heavy-duty compressors, larger reservoirs, and automated controls to keep temperatures stable under continuous load. Industrial chillers also have condensers, evaporators, and automated temperature controls that make them more efficient. They are ideal for multi-welder operations, robotic welding equipment, and production lines where consistent performance is essential.

How to Size a Welding Chiller

Welding chiller sizing depends on the equipment’s heat load, duty cycle, required coolant temperature, flow rate and pressure. Welder kVA alone does not provide enough information to select a system.

For resistance welding, the following formula provides an initial cooling-load estimate:

Estimated cooling load (BTU/hr) = welder kVA × duty cycle × 0.85 × 0.6 × 3,415

Enter duty cycle as a decimal. For example, use 0.20 for a 20% duty cycle. The calculation uses assumed factors of 0.85 and 0.6, which must be checked against the welding equipment and application.

Chiller selection must also account for the required fluid temperature, site conditions and pump performance. For multiple welders, provide the operating schedule and cooling requirements for each machine.
