Seals, Coils and the Refrigerant Charge Decide the Outcome
Pumps and chillers fail in transit for predictable reasons. A pump's shaft, mechanical seal and machined impeller and casing surfaces corrode if humid air sits in an open casing, and the rotating element brinells its bearings if it is left free to turn under vibration. A chiller is even less forgiving: its sealed refrigerant circuit must stay leak-tight, or it loses the factory charge and admits moisture; its evaporator and condenser coils are thin-finned and bend or corrode; and its compressor and controls want the same protection as any other rotating, electronic package.
BENZ protects each on its own terms. Pump internals and machined faces are preserved with VCI, the rotating element is locked, and casing openings are capped. On a chiller the refrigerant circuit is kept sealed and, where the unit has isolation valves, the charge is isolated and held in the condenser per the OEM procedure; the coils are shielded against impact, and the compressor and panel are barrier-wrapped with desiccant. Where space demands, a large chiller is shipped split into its compressor, evaporator, condenser and control-cabinet modules. The complete unit is secured to its skid on its true load path, sealed against humidity for sea transit, and crated on heat-treated timber rated to its weight.
