Description

Medical Gas full Automatic Manifold to medical applications, complies with NFPA99 and ASTM B819 (clean for oxygen use). The parts that make up the construction of our cylinder manifolds are specifically or custom-made, we do not use commercial parts and connectors.

Cabinet:

  • Indoor – Outdoor use, NEMA class 3 IP56 protection level cabinet, Rittal brand powder coating finish with CE certificate.

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 primary and secondary cylinder headers in real time.
  • High and Low pressure Display readings of main supply medical gas in real time.
  • Pressure Units.
  • Alarm signals.

Signals (Alarms):

  • Low delivery pressure alarm.
  • Main cylinder header empty alarm.
  • Backup cylinder header in use alarm.
  • High pressure alarm (above of 20% of nominal pressure).
  • Leak alarm (25% pressure drop detected in the reserve or stand by cylinder header).

By-pass System:

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

Over-pressure and vent valve system:

  • Interconnected pipe circuit system protection relief valves, oriented to the exterior of the cabinet manifold.

Emergency Ports:

  • Located after the end line regulators and low pressure only.
  • DISS DEMAND CGA V-5 coupling according to the medical gas of Manifold.

Pressure Gauges:

  • High and low pressure analog type.

Comunication System:

  • 5 Relay type alarms (Dry Contact) to a 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.
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.
