Product Overview

For over 25 years, Zero Zone has provided custom refrigeration chiller systems for ice rinks and a variety of industrial systems. The chillers are indirect refrigeration systems, utilizing propylene or ethylene glycol. Chillers remove heat from a liquid through a mechanical refrigeration cycle when large capacity cooling is needed . Chiller systems are used in many applications including food processing, distilleries, and manufacturing.

The Zero Zone design uses multiple compressors; this allows for lower operational costs because it better matches the load. For ice rinks this means using more compressors to freeze the ice and fewer to maintain the ice surface. Most Zero Zone ice arena packages include two refrigeration racks, providing redundancy and ensuring that one is always operational. Customers are very pleased with both the reliable performance of our refrigeration chiller systems and their unparalleled energy efficiency.
