Water Cooled MACCOLD Chiller Units are one of the most preferred cooling systems for industrial and commercial use. These units cool the spaces by cooling the water due to their working principle. Water Cooled MACCOLD Chiller Units provide more efficient and quiet operation indoors. However, system installation and maintenance are relatively more complex and may require more space than outdoor installation. Water Cooled MACCOLD Chiller Units provide more stable temperature control in long term operation and emit less noise to the environment, which is why they are especially preferred indoors.
