GAS MANIFOLD MM40 - HP UNIT

Group Number: 3611

Manifold MM40 HP unit is an automatic manifold. It is working on the principal different pressure between the operation and reserve regulator. By the manual lever, the operator can decide which side will be the operational side and which will be the reserve side. When the operating side is empty, the manifold will without any action start to supply gas from the reserve side with the lower regulator pressure and fulfilll the requests to supply without interrupting the flow.

MM40 HP unit manifolds together with a stabilizer should be used as second and third source of gas in systems with liquid gas tank. For hospitals without liquid gas tanks it is possible to use manifold MM40 HP unit together with a stabilizer as first and second source, and in connection with a third source (MM90 Standby) it will provide a final solution to fulfill ISO 7396-1 and national installation standards.

Manifolds are supplied with an Alarm system which increase safety to maximal level and inform the hospital personal about each non standard situation.

Gas Alarm C44 is a standard accessory. The gas alarm C44 gives visual and audible indications.

It surveillance and sounds the alarm when the following happens:

1.  Leaking reserve side
2.  Empty possition (High/Low distribution pressure when connected
     to a Stabilizer)
3.  Change operation side
4.  High intermediate pressure

  • The gas alarm C44 is able to communicate with other equipment through relays.
  • The alarm has a battery back-up for 30 minutes of operation.
  • Manifold MM40 Semiauto is only first stage of regulation and must be installed together with a Stabilizer which will stabilize the final pressure used in the hospital gas outlets.
  • GCE medical manifolds are CE-marked and fulfill the ISO 7396-1 standard.
