Degasifiers

Degasifiers

The function of degasifiers is to suck the air bubbles that remain in the synthetic resin or composite material mixes and in silicon or similar compounds during their preparation. The presence of bubbles, in fact causes a drastic reduction of their technical features and negatively affects their appearance.
Degasifiers are composed of:
- One or two welded sheet steel autoclaves, featuring a perfect vacuum seal, equipped with transparent methacrylate lids that can be manually removed.
- An oil-bath rotating vane pump for high vacuum.
- One or two vacuum switches for a direct reading of the vacuum level in the autoclave.
- One or two three-way manual valves for vacuum interception.
- A switchgear enclosed in a special protective casing.
- A profiled steel frame for assembling all the components.
Inside the autoclave, the degasifiers can reach a final vacuum level equal to 99.5 %. With small modifications and with the aid of insulating or waterproofing resins these degasifiers can be used for vacuum-impregnating windings for electric motors, transformers, electric coils, etc. Upon request they can also be supplied in different versions.

Mobile system for resin vacuum infusion

Mobile system for resin vacuum infusion

This system has been designed for allowing resin vacuum infusion moulding and composite fibre vacuum forming.
The system is composed of:
- A welded sheet steel autoclave featuring a perfect vacuum seal, equipped with a transparent methacrylate lid that can be manually removed.
- An oil-bath rotating vane pump, for high vacuum.
- A reducer for adjusting the required vacuum level.
- A vacuum gauge, for a direct reading of the vacuum level in the autoclave.
- A three-way manual valve for pump vacuum interception and for restoring the atmospheric pressure inside the autoclave.
- A two-way valve for vacuum interception at the application.
- A switchgear, enclosed in a special protective casing.
- A profiled steel frame for assembling all the components mounted on wheels.
- An handle to move and place it.
Resin vacuum infusion moulding is carried out connecting the connector controlled by the two-way manual valve to the mould.
The resin inside its container is sucked via the vacuum inside the mould, until it’s totally full. The resin in excess is collected in the autoclave.
The same connector can be connected to the vacuum press bag for forming composite fibres.
The installed vacuum pumps allow reaching a maximum vacuum level of 99.5% inside the autoclave. Therefore, this device can also be used as a degasifier.
The vacuum reducer allows adjusting the vacuum level within a minimum value of
20% a maximum value of 99.5%.
Upon request, they can be supplied in different versions.

Electric equipment for vacuum test

Electric equipment for vacuum test

These devices have been created for testing the weldings and, therefore, the sealing of cellophane or PVC wrappings for food products.
In fact, the wrapping placed inside a bell jar tends to inflate because of the pressure differential created between the air at atmospheric pressure contained inside and the vacuum created inside the bell jar. The higher the vacuum level reached in the bell jar and the greater the thrust that the air contained in the wrapping will exert on the walls and, therefore, on the weldings.
The devices for vacuum tests are composed of:
- A mobile transparent plexiglas bell jar.
- A support surface with seal.
- A dry rotating vane vacuum pump.
- Two 2-way manual valves for vacuum interception.
- A vacuum gauge for a direct reading of the vacuum level.
- A mini vacuum switch for vacuum level adjustment.
- A switchgear enclosed in a special protective casing.
- A bent sheet steel frame with anti-vibration feet for assembling all the components.
The vacuum level that can be reached inside the bell jar depends on the pump installed.
The test values are adjustable and can be automatically repeated. They can be supplied in different versions upon request.

Pneumatic equipment for vacuum test

Pneumatic equipment for vacuum test

The function of these devices is to test the welding sealing in flow-pack, cellophane or food product wrappings. They are composed of:
- A transparent plexiglass cylindrical container into which the water is poured and the vacuum is created.
- A mobile transparent plexiglass lid with, on its lower part, a perforated disc fixed via a pin which is for keeping the flow-pack wrapping submerged in the water, in the container and on its upper part, the instruments for managing and controlling the vacuum.
- A multiple ejector multi-stage vacuum generator.
- A check valve located on the generator suction inlet to prevent the air from returning into the container when the generator is not in operation.
- A sleeve valve for compressed air interception.
- A supply compressed air reducer equipped with pressure gauge.
- A 2-way manual valve for restoring the atmospheric pressure inside the container.
The wrapping submerged in the water in the container tends to inflate because of the pressure differential produced between the air at atmospheric pressure on its inside and the vacuum created in the container. The higher the vacuum level reached in the bell jar and the greater the thrust that the air contained in the wrapping will exert on the walls and, therefore, on the weldings. Any air leak from the wrapping due to a defecting welding is proved by bubbles that indicate the exact point of the welding that’s leaking. The vacuum level that can be reached inside the bell jar depends on the pump installed. The test values are adjustable and can be automatically repeated. They can be supplied in different versions upon request.

Suction units with syphon filter ga fs 5 and ga fs 10

Suction units with syphon filter ga fs 5 and ga fs 10

These suction units with syphon filter allow sucking fluids saturated with condensation or mixed with water and liquids.
They share all the best technical features of syphon filters and vacuum generators. In fact, they keep liquids and solid impurities, while the vacuum generator can suck fluids saturated with vapours or liquid condensation without compromising its performance.
These devices are composed of:
- A standard syphon filter described in Chapter 5.
- A compressed air-fed multi-stage vacuum generator.
- A pneumatic vacuum switch for vacuum level adjustment.
- A vacuum gauge for a direct reading of the vacuum level in the container.
- A pneumatic valve managed by the vacuum switch for supplying the vacuum generator.
- A sleeve valve for compressed air interception.
The vacuum level, preset with the vacuum switch, is automatically maintained in the plexiglas container. These suction units with syphon filter are suited for vacuum cup clamping systems for gripping glass, marble, granite, light alloys and in all those cases with a considerable presence of refrigerating liquids.
They are also recommended for sucking creamy or muddy substances, hard to handle with traditional pumps. These suction assemblies are fed by compressed air at a pressure of 4÷6 bar (g) only. Upon request they can also be supplied in different versions.

Safety suction units with syphon filter

Safety suction units with syphon filter

These units have the same functions as the previous ones, but they differ for their automation and composition. In fact, these devices are composed of:
- A standard syphon filter already described in Chapter 5.
- Two compressed air-operated multistage vacuum generators with built-in energy-saving system ES.
- A vacuum gauge for a direct reading of the vacuum level in the container.
- Two sleeve valves for compressed air interception.
These safety suction units normally provide for the operation of one vacuum generator with subsequent automatic insertion of the other one for higher consumptions and when, for whatever reason, the plant vacuum level goes below the preset minimum value. All this also guarantees continuous operation even in presence of a vacuum generator breakdown. The vacuum level, preset with the vacuum switch, is automatically maintained in the plexiglas container. These suction units with syphon filter are suited for vacuum cup clamping systems for gripping glass, marble, granite, light alloys and in all those cases with a considerable presence of refrigerating liquids.
