• Cold Flow Manager (CFM)

    Description

    A common safety challenge in cold temperature working conditions is maintaining hydraulic flow during operations. Our new, patent pending Cold Flow Manager (CFM) not only accelerates wellhead safety equipment operation, but it also requires minimal components and has a “plug and play” capability with existing equipment.

    Our design is more affordable and dependable than other methods, and it’s unique simplicity makes it particularly practical. It supplies hydraulic flow from all of the control hoses on the well control power system and delivers it all to the one set of BOP rams selected. The high fluid viscosity due to low outside temperatures is overcome by the CFM’s focused flow.

    We understand your need for quick BOP ram actuation. Adding only the CFM to the well control system, we have been able to increase flow 3 to 4 times when compared to a standard BOP supply system. Further, adding relatively small accumulators to the supply and return sides of the CFM, allows a selectable flow increase of up to 9 times flow. This increased flow gives the ability to operate the BOP in cold temperatures with a timely response.
