Project: Medical Equipment Cooling
Cooling Approach: Water-cooled
Cooling Approach: Allengers, an Indian leading Indian medical equipment manufacturer, needs a compact, portable water chiller for their laser medical device. The chiller must reduce 4 liters of pure water from 32°C to 21°C within 11 minutes, with low vibration and noise. Considering the quiet requirements of their medical equipment, ARCTIC abandoned the traditional AC compressor and adopted a miniature DC inverter compressor, specially customized a chiller for laser medical equipment with low vibration, low noise, and high refrigeration efficiency.
Recommended products: Coaxial Liquid Chiller – DV3220E-C

Background

Allengers Medical Systems Ltd., based in Chandigarh, India, has been a leader in medical diagnostic equipment since 1987. They require a compact, portable water cooler for their laser medical device capable of reducing 4 liters of pure water from 32°C to 21°C in 11 minutes with minimal noise and vibration.

ARCTIC offers a custom solution using a miniature DC inverter compressor with a 300W cooling capacity, fitting within 800x400x350 mm. This chiller meets Allengers’ strict requirements for efficiency, precision, and quiet operation, reflecting their commitment to innovation and excellence in healthcare technology.
