CC Hydrosonics Ecology AVD 1000 Ultrasonic Solvent Degreasing MachineSystem overview

The AVD1000 is a Twin Sump Immersion Solvent Cleaning System which incorporates the technical capability ofrunning a wide range of non flammable Chlorinated Solvents, via simple temperature adjustment

On initial heat‐up mode the unit will call on the electrical heaterpower, this power input is sufficient to quickly establish a vapour blanket.

When the probe senses that the hot vapour is present, the PLC will pulse the sump heat maintaining a stable vapourBlanket, reducing input energy cost whilst maintaining solvent consumption. By adjusting the PulseRate of the Heaters, control on the distillation rate can be achieved.

The ultrasonic sump comes with 2000W 40Khz ultrasonics and a recirculation pump with filtration loop.

The system has two air conditioning compressors with four sided condensing coils. The temperature controller of thecompressor provides fine adjustment on defrost mode setting to prevent icing on the cooling coil.

The system is designed with 150% freeboard area and four sided extractions.

Safety thermostats are built‐in for high solvent temperature and high vapour temperature cut outs as well as lowliquid cut off.

Solvent vapour liquid offers a quick and efficient method of removing oil, tar and grease and insoluble solids from alltypes of machined and fabricated parts.

The solvent is heated in the Vapour Generator Sump of the tank. The vapour which is formed is approximately fourtimes as heavy as air and therefore, tends to stay in the tank and, in all respects, acts as a liquid.

Cleaning Cycle

As the parts enter the process chamber they are cooler than the temperature of thevapour, this condenses to liquid solvent on the surface of the parts.

In removing the latent heat from the vapour to convert back to solvent, the parts absorb heat increasing their owntemperature.

With thin sheet or small parts, this occurs very rapidly and condensation will cease completely within a very shorttime. This can be seen because there is no solvent then dripping from the parts into the sump.

On immersion into the sump, hot liquid solvent and the use of ultrasonic cavitation removes the oil, grease and dirtfrom the surface of the parts, flushing them into the sump of the tank.

The next stage of the cycle is to raise the parts back into the vapour area. Vapour will once more condense to liquidsolvent, flushing the surface of the parts to give a final clean and, as the parts heat up to the temperature of thevapour, they can then be moved into the vapour air interface area and be allowed to cool and ʺflash dryʺ.

Construction

The system tank is fabricated from a high grade, bright‐annealed stainless steel with double‐sided welded andpolished for added durability and minimum contamination entrapment.

The tank is housed inside a stainless steel grade 304 framework. All panels, covers, countertop, lid and control panel are also fabricated of hairline‐polished stainless steel.

The process tank is positioned towards the front portion of the frame for ease of accessibility and operation. The totalheight of the system is considerably lower than most other vapour degreasing systems in the market, while notcompromising on safety requirements and design guidelines.

Specific Safety Features:

Low Level Safety Solvent SensorsHigh Sump Contamination IndicationFour Sided CooledCondensing CoilsElectronic Vapour Control System150% Freeboard AreaHigh Vapor Level Safety Cut‐Out DeviceFour Sided Lip Extract SystemClear View Sliding Access Doors

Sealing Lids

The system incorporates dual protection access, firstly through the interlocked sliding front doors, whereby theoperator can load the basket onto the work platform. Once and only once these doors are closed the inner horizontalsealing lids will open to allow ingress into the cleaning system with the auto lifting system. Once the basket entersthe cleaning tank the sealing lids will again close fully protecting the operator from any solvent exposure.

Solvent monitoring.

The system has incorporated a Murco solvent PPM monitor fitted, which inhibits the opening of the front doors untilany latent solvent present in the loading chamber reaches the desired set PPM value.

Sumps

The tank comprises of two sumps. The ultrasonic sump which has an internal capacity of 768 litres and the boilingsump which has an internal capacity of 180 litres. The system overall contains 986 litres including the filtrationsystem.

The first sump is called the ultrasonic sump.

features of this sump are as follows:

The second sump is the boiling sump to provide the vapour blanket over the ultrasonic immersion tank

Features of this sump are as follows:

1.0KW of stainless steel immersion heaterA low liquid level sensor tocut off the heater should the solvent level fall dangerously low.A drain line with a manual ball valve is plumbed directly in front to the bottom of the sump

Above the tank is located the condensing system which is a four‐sidedchannel. The cooling coils are directly above this channel.Vapour condenses on the channel and flows through a ½” coupling into a water separator.

The gravity separator type water separator.

The designrelies on the difference in specific gravity between water and the chlorinated solvent. Water being lighter, floats onthe surface.

The cooling of the solvent releases water which may be in solution and this floats as small waterparticles to the surface.

These coalesce into large bubbles and the whole surface over a period of time becomes covered with a film of water. This increase over a period of time until it can be removed using the valve fitted on the side of the separator.

The solvent will flow back into the immersion sump which will subsequently cascade back to replenish thesolvent in the boiling sump.

Cooling Coils

There are two sets of cooling coils in this dual‐compressor system. The first set is called the primary cooling coiland is directly above the condensing channel.

This is the main set of coils responsible for condensing the vapour, It is fed by a refrigeration unit (compressor)charged with the environmentally friendly refrigerant.

The sophisticated patented Vaportronic control via a PT100 probe at the lower proximity of this set of coils efficientlycontrols the vapour level for minimising vapour loss while saving energy.

The second set of coils is called the freeboard cooling coil and is spiralling right above the primary set. This is fed byrefrigerant from a second compressor unit.

Compressors

The two units are of identical models, both of them are charged with R404 environmentally friendly refrigerant.

These refrigeration units are also equipped with a defrost system to ensure optimum blanketing of cold air over thevapour zone for maximum vapour condensation.

Lip Extraction

The system incorporates a four‐sided lip extraction system. Recommended air velocity through the extraction gap is0.7m/s.

A mini blower fan attached to the back of the tank extracts the air via flexible ducting and must vent directly toatmosphere. This is adjustable via a damper.

Auto lifter

A pneumatically driven lifter is installed to automate the cleaning process. The HC11 PLC controlled lifter is used totransfer the basket though the cleaning process in a controlled manner to minimise solvent drag out.

Advantages of Solvent Cleaning

Reduced Labour Costs. Work can be left to clean whilst other jobs are completed.

Fast No waiting. Cleaning anddegreasing takes only a short time. Parts are removed clean and dry already for the next operation.

Better cleaning.Extremely efficient cleaning, clean solvent is used at all times. No re‐depositing of oils as in soak, wipe, dip andspray systems.
