Screen Changers for Polymer Melt Filtration -- Cooling Water Flow Manifold Overview


Hitech™ cooling water flow manifold components are:

  • 3 independent flow channels for Inlet Flange, Cooling Chamber and Exit Lip

  • made of corrosion resistant materials

  • shipped pre-assembled

  • includes j-boxes and cables for inter-wiring by customer with the supplied controls

  • hydrostatically tested to prevent leaks

  • equipped with sight flow indicators (offering a visual means of assuring water flow)

  • protected for back flow by check valves 

  • protected by water strainer

  • protected from steam build-up by a relief valve

  • operated by solenoid valves (air) (24 VCD/110 VAC/ 240 VAC)

  • solenoid valves protected by supplied air filter

  • air operated WATER flow valves

  • flow monitored via flow meter with output relay interlocked with the controls for alarm in a NO FLOW (no cooling or low cooling) condition

  • optional metering valves for custom applications

  • used in conjunction with our controls, the customer has available several  heating/cooling patterns to suit the process, resulting in optimized reaction time and minimized incidence of blow-outs

  • alternative cooling water system circuit available for installation where frequent accidental power shut off are expected
