GAS MANIFOLD DUPLEX (MC80)

Group Number: 3611

The MC80 gas manifold is suitable for medium to large sized hospital. It has a flow capacity up to 200 m3/h and is conveniently designed in modules. The MC80 reduces the gas pressure in two steps to a constant distribution pressure. Service and tests can be carried out with no disturbance in the supply of gas to the gas distribution system.

THE DUPLEX MC80 CONSIST OF THE THREE FOLLOWING UNITS:

1. MC80 - HIGH PRESSURE UNIT

This module contains two regulators with safety valves and it is connected to two various cylinder banks with high pressure hoses. When the cylinder bank which has been connected for operation, has been emptied, the other duty side is automatically connected.

2. MC80 - STABILIZER

The stabilizer makes the operating pressure in the distribution system remain constant. The module contains two regulators with safety valves. Since the gas pressure is reduced in two steps the drop in pressure, when changing from the operating cylinder to the other bank of cylinders, is kept to a minimum. The unit is prepared for connection to a liquid Oxygen supply tank (LOX).

3. GAS ALARM SYSTEM - based on the product variant

Alarm systems from GCE are user friendly solutions, with simple control and lots of extra functionality. It surveils electronically and the alarm sounds when the following happens:

1.   Too high or too low distributing pressure,
2.   Too high intermediate pressure,
3.   Leakage on the reserve gas cylinder bank,
4.   When change of operating side has been effected,
5.   Weak back up battery.

When connected to a liquid tank the following disturbances will be reported:

1.   Too high or too low distribution pressure,
2.   Too high intermediate pressure,
3.   Leakage from the reserves,
4.   When change of operating side has been effected.

The product is either equipped with an alarm system or a sensor only (as stated in column "Alarm" in the product table below).
