Welding chillers

May 20, 2021

Without proper temperature regulation, a lot of manufacturing processes that are heat sensitive will either deteriorate or result in an altered finished product. Various types of industrial chillers are available for widespread use in metallurgy and industrial welding. Industrial welding chillers for resistance welding like spot welding, MIG welding, and TIG welding can help improve product quality and process efficiency.

Welding chillers are commonly used for resistance welding and its variations such as spot welding, as well as TIG and MIG welding. Chillers or recirculating water systems are used to control electrode tip temperature. Over time, chillers have progressively replaced recirculating city-water systems because they are less costly to operate and can provide more accurate temperature control.

Welding heat is the most significant parameter to control, because it directly correlates with how much current can be consistently applied to each weld. When using a chiller, steadier welding current can be produced and therefore a consistent amount of heat is applied to every weld. Welding tips last longer, and welded part production improves, all while ensuring project repeatability.

In production environments with multiple welders or robotic welding systems, one central chiller can be used to manage all equipment. A general rule for sizing chillers is to plan for a 1-ton of chilling for every 100KVA of welder capacity.

All of oumal welding process chillers feature a variable-speed compressor and condenser fan for higher efficiency, precision temperature control within 0.5°, reliability and quieter operation. They are available as portable units (1-30 tons) or as large-capacity packaged chillers (40, 50, or 60 tons). Modular chillers are available over 60 tons. All of our chillers can be used on new welding equipment, or be used to upgrade or replace existing welding chiller systems.

Oumal has been manufacturing temperature control units and process chillers for over 15 years. Our team of knowledgeable engineers can help with any welding chiller solution. Our insightful sales and support staff are available to assist with application questions, as well as standard and custom product specifications that ensure successful installation, operation, and maintenance.

A more accurate way of determining appropriate chiller size is by computing BTU using a standard formula that also accounts for the duty cycle.

To calculate for resistance welding:

BTU/hr = (welder KVA) x (duty cycle) x (0.85) x (0.6) x 3415 BTU/hr

To calculate for resistance welding:

BTU/hr = (welder KVA) x (duty cycle) x (Eff power supply) x (Eff heat collection) x 3415

Eff. power supply = the percentage of output to input power

Eff. heat collection = the percentage of heat absorbed by chilling water (varies by approximately 50-70%)

Duty cycle = weld time on/ time elapsed

Our process chillers can easily be customized and used to fit any welding need, as a spot-welder cooler, TIG-welder water cooler, or any other scenario. To discuss your welding chiller needs and goals with our experts request a quote or contact us today!
