TCI Mechanical improved the functionality of a yacht’s refrigeration system with a complete modernizing retrofit. We designed and fabricated six refrigeration systems including a 316 L stainless stacking frame. These systems were equipped with custom motor-operated valves and special gauge manifolds. We installed two separate circuit alarms for high and low temperature alerts that were connected directly to the vessel’s central control systems. One four-stack unit and two two-stack units were placed in the engine room with specialty made mounting foundations.
