TCC Optimum™

TCC Optimum

Light on Weight, Heavy on Features

No on-site lab? Meet the Welker TCC Optimum™: the only crude oil container on the market with DOT and Transport Canada approval. With the compact TCC Optimum™ as your primary container, safely getting your composite sample of stabilized crude to an off-site lab for mixing and analysis is possible. Special design features exceed industry standards and improve the operator experience.

Complies WithAPI Chapter 8, ASTM D4057, ASTM D4177, ASTM D5854, ISO 3170, ISO 3171
ASME code stampedU code; ASME Boiler and Pressure Vessel Code (BPVC) Section VIII
Transport Approval*DOT and Transport Canada (DOT-SP 16074; TC-SU 11319)
A Shining Example

ProSlick™ Finish

Our proprietary ProSlick™ finish does more than dazzle the eyes. The smooth, mirrored finish optimizes sample quality and improves the operator experience. Unable to stick to the finished interior, water can’t avoid being mixed into the sample, so you can be confident in the accuracy of your water cut measurements. The repellent effect of the ProSlick™ finish makes cleaning the container inside and out a breeze—preparing for the next sample batch just got easier.
