The MK4 7″ AVS has completed its design, manufacture and build and is now ready for extensive testing on the C&W Flowloop at our Sheffield facility. The major differences of the MK4 to previous versions is the overall packaging which has reduced the length by over 1m. We have a revised selector ring assembly, pre fabricated encapsulated wiring harness, improved electronics increasing battery efficiency, numerous mechanical enhancements to improve efficiency and reliability. In addition, the tool can now be programmed with the V2 software from a single external access port. This delivers reduced service and maintenance costs. A huge thanks to the OGTC and Lundin Energy for their support in delivering the MK4.
