Description

Medical Gas Automatic Manifold for Deward type cylinder headers, meeting NFPA99 and ASTM B819 (clean for oxygen use).

Cabinet:

  • In door
  • IP56 Weatherproof

Control System:

  • High speed electronic PCB with 7 " full color LCD display, touch screen control.
  • 110-220 vac normally open electric valve.
  • Non-return valves
  • 4-20Map high and low pressure transducers

Graphics:

  • High and Low pressure Display readings for primary and secondary deward cylinder headers in real time.
  • High and Low pressure Display readings for manifold final pressure delivery in real time.
  • Pressure units.
  • Alarm signals.

Signals (Alarms):

  • Low pressure in the Manifold
  • High pressure in the Manifold
  • Alternate or External source supply pressure in the Manifold.
  • Leak Detection for reserve cylinder header (20% decrease in static pressure).
  • Cylinder headers switchover, primary to secondary and vice versa.

Minimum Pressure of Deward Cylinders:

  • 230 PSI

By-pass System:

  • 2 low pressure final line regulators with manual isolation stainless steel ball valves (one regulator in use and the other in reserve).

Over-pressure and vent valve system:

  • Interconnected circuit protection system of relief valves, over-pressure guided to the exterior of cabinet manifold.

Comunication System:

  • 5 alarms Dry Contact connections (low delivery pressure, empty cilynder in use, reserve in use, high delivery pressure, reserve tank leak) to zone and master panel alarm remote connection, as well an integration of a remote monitoring and administration system BMS (Building Management System) common language based on relay switching.
  • Two-wire Modbus RTU RS485 communication in slave mode for monitoring pressures in PSI units and alarm conditions from a BMS (Building Management System), SCADA (Supervisory Control and Data Acquisition) system or any equipment configured as master panel.
  • Main Cilynder Header use choosing button.

Emergency Ports:

  • Located Before end-line regulators and only for low pressure 50-55 PSI.
  • Coupling with CGA inlet according to the medical gas of the Manifold.

Pressure Gauges:

  • To high and low pressure analog type.
Warning:
  • Do not use Oil and its Derivatives.
  • Operation and maintenance personnel must be certified for the manifold safe operation.
  • Quality and Medical Gases Purity Degree, as well condition of containers, cylinders and their connections will be always responsibility of the medical gases supplier.
  • Deward cylinder evaporators must work properly in the event of an oxygen over demand to avoid freezing of the manifold due to inefficient liquid evaporation.
  • An external vaporizer with sufficient capacity for consumer demand should be used in case that Deward cylinder evaporators will be insufficient.

Specifications

Cylinder Headers:
  • Modular Assembly.
  • Red brass tube special extrusion SPS alloy 23000, H58 Drawn temper made, complies with ASTM B-43-98, ASTM B-819 (Clean for oxygen use) 3,000 PSI working pressure.
  • CGA connection points for each cylinder with self-closing non-return valves (check) brass made.
  • Manual master valve to opening and closing control of the primary and secondary cylinder headers.
  • Relief valve to each cylinder headers.
Pigtails:
  • Cryogenic: Flexible rubber hose, CGA connection for the specific gas.
Available Gases:
  • CGA540 Oxygen Deward type 230PSI minimum pressure.
  • Low pressure (50-55psi) emergency input CGA540 coupling port, for a backup header to medical gas automatic manifold deward type.
  • Liquid Nitrogen cryogenic systems CGA 580 connection for Dewar type cylinders, complies with NFPA99-2015, includes emergency inlet in low pressure stage.
Require:
  • 100-220 V 50-60 Htz. power supply
  • External evaporators in case of an oxygen over demand that freezes the system
  • A source primary supply bulk (microbulk) in case of an oxygen over demand that freezes the manifold, (The manifold becomes a secondary or backup source).
