Unrestricted flow for liquid cooling

Where unrestricted and high-flow cooling disconnects are the key, CEJN’s easy to handle Full-Flow coupling series are easy to install, and due to the valveless design, allow for an unrestricted high-flow.


Valveless design

The Full-Flow range is designed for low-pressure fluid cooling applications such as renewable energy solutions and power electronics, but can also be found in larger pneumatic lines. The economical valveless design permits unrestricted high flow, a real advantage when connecting high-flow rate circuits within thermal control management.


Optimized for main supply lines

The Full-Flow couplings are a perfect fit for applications such as main supply lines within power electronics, renewable energy solutions, etc. where the benefits of non-drip quick couplings are not required. The straightforward design reduces pressure drop and makes it easy to maintain and service. The robust and corrosion-resistant range is available in nickel-plated brass or stainless AISI 316 with a wide range of sealing options, such as EPDM, NBR, FPM, etc.
