View James Caylor's Expert Witness Profile.
Evaporator leaks expose plant personnel to risk of ammonia contact and require maintenance intervention since refrigeration control valves used for inlet flows (liquid and hot gas) can automatically stop flow, but similar valves used for outlet flows (suction and refrigerant defrost condensate) cannot stop flow backwards from the suction line into a damaged evaporator and thus into the conditioned space.
