Mission Critical Chiller
Technical Systems (TSI) Series 30A3 package air cooled chiller units have been specifically designed for mission critical facilities that have stringent requirements for reliable and efficient equipment. These facilities run 24 hours/7 days, all year long and cannot afford operation downtime in their cooling equipment services. The 30A3 series chillers focus on reliability, adaptability and efficiency. Units include ASHRAE 90.1 compliance, walk-in service, acoustically treated components and true open protocol controls, all coupled with inherent redundancy. We offer several different cabinet sizes to meet your needs and factory run (functional) test for all chillers prior to shipment as a standard option every day. Our combined capability of specific application engineering and expertise in manufacturing custom equipment will provide limitless solutions for your needs.
