    Solutions Engineering

    The range and complexity of industrial applications means a 'one size fits all' policy does not result in system optimization. A detailed appreciation of the process, environmental and safety issues is required to tailor systems to match performance and process.

    Applications Design & Support

    Edwards comprehensive design service is based on in-depth knowledge of the industries and applications involved. This expertise is held in the highly focused and experienced applications team, which consists of a Central Applications Group supported by a regional network of Applications Specialists. Proprietary software is used to define pumping requirements and a suite of optional accessories or modules are available. For larger or more unusual applications a custom engineering service is available.

    Solutions could cover:

    • Process design
    • Equipment selection
    • Safety and Operating Parameters
    • Integration with plant control system(s)
    • Commissioning advice and more...

    Contact your local office to request an initial discussion with an Applications Specialist. Typically, discussions will include gases / materials to be pumped, cycle times and duty pressures, system capacities, control systems, utilities, system footprint and all other aspects of the vacuum system to ensure that we are able to offer the most effective solution for your application.

    Modular & Custom Accessories

    Accessory modules allow systems to be produced that address customer requirements without impacting on system lead times and allow a highly flexible approach to solutions engineering.

    Accessory modules offered include:

    Gas Purges

    Gas purge can be nitrogen, CDA (Clean Dry Air) or atmospheric air. They are used to protect seals, clean/blow through dust and particulates, cooling the gas load, etc. Options available are shown below and all are available with a control panel.

    • Shaft seal purge
    • Gas ballast purge
    • Exhaust purge
    • Atmospheric purge
    • High flow air purge (see filtration)

    Utilities Control Panel

    Water and gas may be monitored and controlled by the addition of a gas panel. The panel also allows full integration with supervisory control systems.

    GV/GVM Temperature Control

    The pumps are supplied as directly cooled as standard but, where poor quality cooling water is available or increased temperature control is required, an indirect cooling system can be specified. This module uses an external heat exchanger and an adjustable TCV (Temperature Control Valve) to set operating temperature. Options are:

    • Direct cooled -pump only
    • Direct cooled -pump and booster
    • Indirectly cooled -pump only
    • Indirectly cooled pump, directly cooled booster

    All of the above options are available with a control panel.

    • Air blast cooling may be specified and sized to suit the system heat load

    IDX Temperature Control

    These pumps are supplied with indirect cooling as standard fitting.

    Mechanical Boosters

    Addition of a booster provides increased pumping speed & improved ultimate. The GV and GVM ranges are available with EH hydro-kinetically driven boosters and Stokes 6" series direct drive mechanical boosters directly mounted onto the pump. The pumps are also suitable for backing larger boosters, such as Edwards HV range.

    Boosters are available with:

    • Cooling options
    • Rotation & pressure sensors
    • Variable speed drives
    • By-pass valve technology for shortened pump down times

    Acoustics

    Silencers reduce pulsations in the exhaust and hence noise in the exhaust line.

    They also act as a dust trap and can accumulate condensates. All silencers are drainable and for high dust loads, a cleanable unit is available. This allows the silencer to be cleaned without breaking the process line. Enclosures are lined by foam panels with absorbance frequencies that match the pumping system and reduce system noise by >5dB(A).

    • Silencers - stainless steel, drainable
    • Silencer - stainless or mild steel, cleanable and drainable
    • Full system enclosures

    Filtration

    Many industrial processes produce large quantities of dust of varying particle size that may also be wet, pyrophoric or corrosive. Edwards recommend that the main dust load is removed before the inlet of the pump and offer the following:

    • ITF filters for dry dust
    • ITM filters for wet dust or backing diffusion pumps
    • High flow air purge (700 mbar) to blow dust build up though the pump as required

    Local Control Panels

    For all systems supplied by Edwards a range of control panels are available. They vary in sophistication and are designed to offer basic control through to complete plc-based control.

    Edwards have pioneered the use of dry vacuum pumps in some of the most harsh applications. With over 20 years experience and more than 100,000 Drystar pumps installed world-wide.

    Our GV Drystar pumps are designed to handle large volumes of dust and water vapor without the risk of process contamination while maintaining high levels of repeatability, performance and reliability.

    The GV80 Drystar pumps have a displacement of (91.5m3hr-1) and can be coupled with the Edwards EH series mechanical booster for increased pumping performance.
