Corval provided a new, field-erected refrigeration system for room cooling and freeze drying processes for this WellPet facility. The project included the engineering, design, 3D drawings, controls, and a Process Safety Management program. A two-stage system was installed with the low side (-30°F) for 170 TR expandable to 700 TR and a high side (20°F) for 300 TR expandable to 1000 TR. The freeze dryer installation and modification included refrigeration design of the manifold and refrigeration system within the freeze dryers themselves.
A recirculator, intercooler, high pressure receiver, and condenser were installed and all controls and MCC were provided for refrigeration equipment, valves, and instrumentation. VFDs on each suction level were used for energy and low-load situations.
Corval continues to be a strategic partner for Wellpet and their ammonia refrigeration system, and we complete refrigeration maintenance, including PSM-required inspections. One additional freeze dryer has been installed for a total of seven 7 freeze dryers online.
