UNIT NUMBER IS KEY TO DERRICK SERVICE
All inquiries to Derrick must include the equipment unit number. The
stainless steel unit number tag attached to each piece of Derrick equipment
is your key to efficient service and support.
This unique number gives vital information to Service personnel who use it to
identify the correct parts when filling orders, provide accurate responses to
service questions, track documentation, and trace the equipment's history or
configuration. In short, the unit number provides the critical information
needed to ensure that Derrick customers receive the best possible
service.
The unit number consists of a two-character alphabetic prefix that identifies
the equipment type and a series of numeric characters that signify the
sequence of the machine's manufacture. For example, unit number
MA000001 would be the first screening machine manufactured by Derrick.
Alphabetic prefixes currently in use are:
MA - Screening Machine
DG - Degasser
CF - Centrifuge
To ensure that it will remain intact over many years of rigorous service, the
heavy-gage tag is riveted to a structural member such as the shaker support
structure. It is not to be confused with any other identifier on the machine
such as a vibrator motor serial number.
For convenient availability, the unit number is also recorded in the Operation
and Maintenance manual shipped with the equipment. When contacting
Derrick for any equipment question or need, always have the unit number in
your possession. It's the best way to get the most efficient service from our
dedicated Service and Engineering personnel.
