Refrigerated Air Dryer is a service part that should be quoted by Customer Care if customer has a good Zeiss part number 6 digits – 4 digits – 3 digits (xxxxxx-xxxx-xxx). If not, customer can go to CIC, and Hardware Tech Support can provide the Zeiss part number for the appropriate Refrigerated Air Dryer to suit the customer specific serial number machine.
A Refrigerated Air Dryer is an external device, to remove moisture from the air lines that provide the air to the machine air bearings, and is something that a customer can install on their own without need of a Zeiss service technician.
Aftermarket does not receive sales credit for a Refrigerated Air Dryer because it is a service part and not an accessory.
