  • Advanced Vacuum Drying Trials - a Visit from Key Stakeholders

    A few weeks ago, MechaTech Systems were delighted to welcome key stakeholders from Sellafield Ltd, the NDA and TDA to our second unit in Berkeley, where we are conducting a programme of full-scale, in-active vacuum drying trials for Sellafield. The trials are being carried out using simulant nuclear waste in the Advanced Vacuum Drying System (AVDS) . The AVDS, manufactured by north Bristol based MechaTech Systems Ltd, is designed to condition waste in ductile cast iron containers. Conditioning removes the free water and subsequent moisture content, in its original container, down to acceptable levels for interim and long-term storage, transport and eventual disposal. The AVDS was originally designed in a collaborative effort by MechaTech Systems and Magnox - now NRS Ltd – as an alternative to concrete encapsulation of nuclear waste. The system won the Magnox i4 innovation award in 2014 and MechaTech Systems were highly commended by the NDA for the best application of an innovative solution. Today, the AVDS is actively conditioning ILW at nuclear decommissioning sites in the UK. To date, MechaTech Systems have delivered five AVDS to UK nuclear decommissioning sites, are currently working on a sixth system and provide scheduled maintenance and upgrades. The recent visit proved a great success, presenting an excellent opportunity for the MechaTech Systems’ team to meet with key stakeholders who were able view the AVDS trials configuration and discuss progress, key features and potential future uses of the AVDS.  For further information about the AVDS, please visit: www.mechatechsystems.co.uk/advanced-vacuum-drying-system-avds Or contact us: enquiries@mechatechsystems.co.uk  / +44 (0) 1454 414723

  • Comparing Freeze Dryer Chambers: Finding the Best Fit for Your Laboratory Freeze Dryer

    MechaTech Systems supply freeze dryer chambers and spare parts which are suitable for use with our own range of LyoDry freeze dryers and Edwards Modulyo and Supermodulyo freeze dryers. Read on to compare and find the best fit for your laboratory freeze dryer. LyoDry laboratory freeze dryers (including Benchtop and Midi lyophilizers) were originally designed to directly replace Edwards Modulyo and Supermodulyo freeze dryers. So, our freeze dryer accessories and spares are usually compatible with Edwards freeze dryers too. If you're unsure, we will be pleased to check this for you. Our most popular drying chamber is the Acrylic Chamber (part number LSDC) The acrylic chamber directly replaces the Edwards acrylic chamber (part number F056-52-000) and is supplied complete with removable lid and 2 x L-gaskets. Measuring 350mm diameter x 435mm high, it is ideal for a wide range of bulk freeze drying applications. Alternatively, if you need a smaller, cheaper option, the Acrylic Bell Jar (part number LSDCS) measures 212mm diameter x 215mm working height and is supplied with the L-gasket. The Acrylic Chamber (LSDC) is commonly used with the 6-Tray Drying Rack (part number LSD6) with removable stainless steel trays, Each individual tray is 284mm diameter x 30mm high providing a total drying area of 0.38m², enabling freeze drying of multiple samples in a single cycle. Alternatively, we also supply a 2-Tray Drying Rack (part number LSD2) which has 2 x flat stainless steel trays each measuring 310mm, with a height of 132.5mm between each layer. Need to freeze dry faster? The Heated Tray Drying Accessory (part number LSAD6H) which includes the acrylic chamber and 6-tray accessory adds energy in the form of heat via heater mats and a temperature controller (0°C – 60°C). If you need the ability to freeze dry in flasks as well as bulk samples, the Acrylic Chamber with 8-port lid (part number LSDCV) can be used with either of the tray accessories mentioned above. Each of the 8 ports is fitted with a neoprene valve, 3/4" ID, suitable for flasks of up to 1 litre capacity. Or, if you are only freeze drying in flasks and need larger volume, the 24-port column manifold (part number LSPM24) in stainless steel is supplied complete with 24 neoprene valves mounted radially around the column, each of which are 3/4" ID, and suitable for flasks of up to 1 litre capacity. We also supply the neoprene valves (part number LSRV) individually too, along with B19, B24 and B29 rubber adaptors (which connect the valve to the manifold). If you already have an Edwards column manifold or drum manifold and just need replacement valves, these are compatible too, directly replacing the old Edwards part number, F056-48-000. For freeze drying in ampoules, we supply Spin Freezers and Secondary Drying Manifolds , either with your new LyoDry Benchtop or Midi freeze dryer, or as replacements to suit your Edwards Modulyo or Supermodulyo freeze dryer. The Spin Freezer (part number LSSP) employs evaporative cooling and centrifugation to freeze samples in a thin layer on one side of each ampule for faster drying, and it's supplied with 5 interchangeable carriers to accommodate ampoules of varying sizes and capacities. The Secondary Drying Manifold (part number LSDM96) is available with either 96, 48 or 24 ports (part number LSDM96) complete with adaptor nipples for desorption (secondary drying) of samples in ampoules. We also supply spare adaptor nipples (part number LSAN) in packs of 48 units, for the secondary drying manifold (also compatible with the older Edwards secondary drying manifolds). If greater capacity is required but on a laboratory scale budget (as opposed to more expensive pilot scale models), the LyoDry Midi freeze dryer condenser (which replaces the Supermodulyo EF12K condenser) can be used with our 10-tray, stainless steel chamber (part number LSCC10). This provides up to 1.5m² drying area and is available either unheated or heated, and can also be fitted with a manifold assembly for additional flask drying. This chamber can also be retrofitted to a Supermodulyo freeze dryer.

  • Pilot Scale Freeze Drying without the Price Tag

    Benchtop freeze dryers are often used for small scale freeze drying or research and development projects. The choice is sometimes driven more by budget than capacity requirements. What if you need a freeze dryer that is bigger than a benchtop but without the pilot scale price tag? Benchtop freeze dryers are not usually chosen for their capaciousness. LyoDry Benchtop freeze dryers have a 5Kg ice condenser capacity. This means that they will process up to a maximum of 5Kg of the ice that is created from the product moisture, per batch. They are often used with an acrylic chamber and tray accessory for bulk freeze drying. But if you really need a larger freeze dryer, without paying automated pilot scale freeze dryer prices, the LyoDry range of freeze dryers includes more attainable options, such as the LyoDry Midi and LyoDry Midi Pro. The LyoDry Midi freeze dryer condenser is free standing and designed to fit beside a standard laboratory bench (the footprint is analogous to a washing machine, rather than a microwave). The LyoDry Midi has an 18Kg ice condenser capacity, which is useful if you're freeze drying a very wet product and want to freeze dry in larger batches between defrost. The vacuum pump (an Edwards RV12 as standard or an Edwards nXDS15i dry scroll pump if preferred) is integral and easily accessible for maintenance. Like the benchtop freeze dryer, the LyoDry Midi is modular: this means that you can choose your drying chamber and accessory. Thus it can be used with the standard acrylic chamber and tray accessory, just like the benchtop freeze dryer. But if you're really looking to scale up your drying capacity, then the LSCC10 10-tray drying chamber is designed for use with the LyoDry Midi and offers ample volume. LSCC10 has 10 trays, each individual tray measuring 450 mm x 345 mm x 30 mm, giving a total drying area of 1.5m². Available unheated as standard, one option is heating to 60°C. Another option is a manifold valve attachment for flask drying fitted to the side of the chamber. If the LyoDry Midi with LSCC10 chamber sounds appealing but you also need data logging, analysis,pressure control, USB and ethernet connections, then the LyoDry Midi Pro includes this added functionality. Other advantages of the LyoDry Midi Pro include colour touch screen control and, if used with a heated chamber, pre-programmable freeze drying recipes can be used, simplifying the whole process even further. LyoDry Midi and LyoDry Midi Pro are lab scale freeze dryers with the potential for pilot scale freeze drying more economically.

  • Measuring Hydrogen in Molten Aluminium to avoid Porosity in Aluminium Casting

    Measuring hydrogen in molten aluminium is essential to avoid porosity in castings. When aluminium alloys are in the liquid state, they absorb hydrogen. If this hydrogen is not removed, it can cause porosity in the casting. Porosity is a defect in aluminum casting that can cause a number of problems, including: Reduced strength and durability Increased susceptibility to corrosion Reduced machinability Increased weight Visual defects Hydrogen in molten aluminium and its alloys derive principally from the aluminium – water reaction: 2Al + 3H₂O 4 Al₂O₃ + 3H₂ . Water vapor is a major source of porosity in aluminum castings. It can come from the atmosphere, products of combustion, hygroscopic degassing or fluxing materials, reactive materials in the melt, and hydrated corrosion products on feed material. The hydrogen formed is absorbed by the liquid aluminium and unless most of it is removed by degassing techniques, porosity will be observed in the casting. So, an accurate measurement of hydrogen in the melt before casting is essential to ensure that degassing operations achieve the specified quality acceptance value. This measurement is available on the foundry shop floor, using Hyscan II Hydrogen in Aluminium Analyser, UK manufactured and supported, by MechaTech Systems Ltd. Hyscan II is a hydrogen analyser that measures hydrogen during aluminum alloy processing operations. It uses a quantitative reduced pressure technique to provide the operator with a quantitative measurement of hydrogen in the melt within five minutes of sampling. Hyscan II is a robust and designed specifically for use on the shop floor. It is rugged and easy to operate, and it provides accurate results with less than 5% difference between that of the vacuum sub-fusion method. Hyscan II can be used for a variety of purposes, including quality control, process investigation, and the evaluation of melt treatments. By monitoring hydrogen levels during the casting process, Hyscan II can help to identify potential problems and prevent defects, leading to lower scrap rates, reduced energy and labour costs, and improved product quality. The financial savings from using Hyscan II can be enough to offset the cost of the instrument within one year. Hyscan II is a global leader in the measurement of porosity in aluminum castings. Its proven method and accuracy have made it a trusted tool for production foundries around the world.

  • Vacuum Degassing System with portability

    As High Vacuum Systems specialists, one of our core products is a portable vacuum degassing system, used on oilfields across the globe, to remove air and other gases from drilling fluids, and also for other applications where degassed oil (or an alternative media) is needed. The MechaTech Systems Oil Filling/Degassing Rig comprises a mobile, trolley mounted, glass oil reservoir with fluid and vacuum pumps, and a control panel with vacuum, fluid and temperature instrumentation. During the degassing cycle, the fluid pump continually circulates oil through an in-line filter, heater block and spreader plate, back into the reservoir. Throughout this cycle the chamber is evacuated using the onboard vacuum pump. Temperature and pressure are monitored via gauges mounted on the control panel. During the tool fill cycle, the operator evacuates the tool,then diverts the flow of oil to fill the tool. Oil returning from the tool is passed back into the reservoir. An indicator on the control panel, when illuminated, warns the operator of the need to replace the filter. The trolley is fully portable, fitted with swivel wheels on the front. MechaTech Systems are specialists in the design, manufacture and maintainance of standard and customised vacuum degassing systems for small batch and bulk media types, manual or automated. Customers include international blue chip oilfield service providers, nanotechnology R&D companies, optical, electrical components, pharmaceutical and chemical manufacturers etc both in the UK and internationally.
