1.2.1
Major components
The Pneumatech Medical Gas Solutions Medical Air Plant consists of the following major components:
•
Two or more compressors, up to a maximum of six, any of which can be selected as duty compressor
•
Pump monitors which indicate the status of their respective compressors.
•
Air receivers with manual and auto-drain. A manual bypass should be piped on site (kit available)
•
A dryer frame with two dryer sub-assemblies, each including:
• Manual isolating valves
• Solenoid operating valves
• Heatless desiccant dryer
• Dew point alarm sensor
• Coalescing filter
• Activated carbon filter
• Bacterial filter
• Test point
• Duplex pressure regulator/relief valve assembly
• Dryer control units
• Plant control unit
• Plant to alarm interface
For more information about the specific components, please view the separate instruction manuals which are delivered with the respective machine.
1.2.1.1. Air Compressor
Air plant systems are available with oil-injected screw compressors or oil-free compressors. The later can be of the scroll, tooth or piston type. Each compressor is complete with auto-drain at the compressed air outlet. Each compressor also has temperature and pressure alarm sensors.
1.2.1.2. Air Receivers
One or more air receivers are supplied, and each receiver includes auto-drain with manual bypass, pressure relief valve, and fusible plug.
1.2.1.3. Dryer assembly with central controller
The dryer module consists of two duplex absorber towers containing activated alumina desiccant which reduces water vapour content to less than 1.0 gm/m3. When the plant is in operation one duplex tower is on stream removing water vapour from the air, the other tower is being dried and regenerated bypassing a small purge through it. No heating is required to achieve the specified standard of dryness.
The operation and regeneration cycle is fully automatic, controlled by the Purelogic® central controller, and requires no user input. Each tower is foreseen with a pressure switch. Also a dew point sensor is installed after the dryers so that should a fault occur, either high dew point or low pressure, an alarm signal is received by the control system and the standby dryer is activated. The plant control unit ensures that the dryer air purge does not continue under conditions of no load, ensuring efficient operation regardless of ambient air temperature and humidity.
In the event of a power failure the purge valves will close, and the operating valves will open, to allow the air to continue to reach the distribution system.
The system is intended to meet the specifications as shown in table 1-1.

7.1 Introduction
Pneumatech MGS plant systems are designed to operate with the minimum of maintenance, however regular routine minor maintenance operations are recommended to prove the system integrity.
Maintenance operations should be carried out in accordance with the planned preventative maintenance contract purchased by the customer. Maintenance engineers must fully understand the plant control system and must be conversant with the information contained in this manual.
Service and Maintenance is limited to periodic checking and adjustment, or replacement if necessary, of components that develop a fault.
Warning!
Use of sub-standard or inappropriate parts and materials may damage the plant system and invalidate the warranty.
Warning!
Only use genuine Pneumatech Medical Gas Solutions spare parts.
Maintenance instructions for the dryer and compressor are handled in their respective instruction manuals.
7.2 Air receiver maintenance
The air receivers are designed / selected for specific applications and should not be used for other applications or otherwise modified except after detailed design verification by a competent authority.
The receiver should be regularly checked for condensate, using the manual drain valve, to confirm the correct operation of the auto drain.
The frequency of manual drainage should be determined on the basis of operating experience and dependent upon system air moisture content and the design of the overall system.
The receiver and associated pipe work should be inspected regularly for leaks, damage and signs of corrosion.
It is recommended that new seals and gaskets are used when refitting inspection plugs and door covers. Do not over tighten these closures.
7.3 Pressure relief valves
Pressure relief valves must only be inspected /replaced in accordance with the Pressure Equipment
Regulations 1999 and the Pressure Systems Safety Regulations 2000. As a minimum safety relief valves should be replaced after 5 years.
7.4 Solenoid valve maintenance
Warning!
Before working on solenoid valves isolate from the electrical supply and depressurize the valve.
It is not necessary to remove the solenoid valve from the line for repairs or service. Isolate the dryer first.
Periodic cleaning of the solenoid valves is desirable, the time between each cleaning operation being dependant on the media and service conditions.
Page 19 Medical Air Plant
Installation, Operation and Maintenance Manual
In general, if the voltage to the coil is correct, sluggish valve operation, excessive noise or leakage will indicate that cleaning, service or renewal is required.
7.5 Regulator maintenance
Regulators must only be maintained /replaced in accordance with the Pressure Equipment
Regulations 1999, and the Pressure Systems Safety Regulations 2000. To ensure trouble free service we recommended regulators are replaced or serviced biennially; this work must only be carried out by a competent person.
