Portable chillers provide predictable, uniform cooling of electrodes and electrode holders in resistance spot welding. Available in both air- and water-cooled models, DuraChill units have cooling capacities ranging from 5.2 to 10.5 kW at 68°F (20°C) ambient temperature. The company’s 1.5, 2, and 3 hp models have a 41 to 96°F (5 to 35°C) temperature range and maintain temperature with ±0.9°F (±0.5°C) stability. The 5, 7.5, and 10 hp models maintain temperatures from 32 to 86°F (0 to 30°C) with ±2.0°F stability.
