At Vent-Tech we are extremely proud of our 20-year history of investing in LEV training, equipment and technology to produce the best team and service possible. We are also proud to be at the forefront of raising standards within the LEV industry and making safety a priority for all.
LEV is not a one size fits all. Many factors need to be considered when it comes to LEV design. Environmental and operational factors will have a major impact on the required attributes of your LEV system, so it is of paramount importance that the design is correct.
Factors Considered for Advanced LEV Design
- The size of work area
- The properties of the hazardous material requiring control
- The volume of the hazardous material
- How the operators work
- Does the solution cover the entire process
- Are there any potential explosive risks
What to Expect From the LEV Design Process
Vent-Tech starts every system with a design. Our design service includes a detailed site survey, production of designs and a costing report.
During the design survey we look at the processes taking place, the amount and type of contaminants in the air and discuss the individual needs of the client. Afterall, a system that gets in the way of the operator is unlikely to be used properly.
During a Vent-Tech design visit our engineer will utilise a FARO Focus Core 3D Laser Scanner. This not only allows accurate measurements of buildings and work areas down to a few millimetres but also create accurate 3D models of client’s work areas. The days of sending an engineer to site with a tape-measure are gone and clients can now expect more from their LEV design service.
What are the Benefits of New Technology for LEV Design?
The accuracy of the scanner is incredible, and it takes into account any existing obstacles on walls, floors, ceilings, existing pipework, wall cabinets, and other machinery or access points. This allows the design engineers to work out any logistical issues at the design stage, long before any parts are ordered, or any installation has begun.
The scanner allows us to create a truly bespoke LEV system that is not only fit-for-purpose but works seamlessly with your work area and processes. They can plan ductwork routes to work around existing plant and how staff are using the facility.
After the 3D scans are imported into the CAD software via the cloud, any number of system designers can collaborate on a single project at any given time so every project can benefit from the years of experience that comes from having designed over 400+ bespoke LEV systems. You can see some examples of these here.
As the project starts to take shape, we can present a proposal in an accurate model of the work area so that you can properly visualise how the system will look. This is also very beneficial when discussing duct-runs and filter plant locations as images and videos of the areas being discussed can be shown with models of the plant in place. All of this leaves less ambiguity and a more accurate service. It also provides confidence in knowing exactly what you can expect for your investment.
During the design service, airflow simulations are run to determine whether the hoods will provide adequate control based on the source of the contaminant. Any issues can be picked up long before installation takes place.
You will also benefit from seeing the proposed design in a model of your building, to truly bring the vision to life. We can even walk you around the premises in 1st person (similar to Streetview on Google maps).
What Will You Get in the LEV Design Report?
When all the details have been agreed, we provide you with a design report. As part of these design documents, we provide:
3D Design drawing showing:
- Hoods, type, and size.
- Ductwork, route, and size.
- Discharge stack (if required), size and height.
- Fan and filter (if required) location.
Design file, containing:
- Analysis of hazardous substance and control options required.
- Capture velocities at source of fumes.
- Face velocities of hoods.
- Transport velocities within ducting.
- Discharge velocity at stack termination.
- Fan duty and pressures.
- Fan and filter (if required) specifications.
This tangible report will demonstrate compliance with all relevant regulations including COSHH, Noise at Work, DSEAR and HSG258 control benchmarking for hazardous substances.
The whole experience means that you will be completely satisfied with the project before moving to the next step and have all the required information to become an informed buyer.
Vent-Tech are proud to be providing a cutting edge and bespoke LEV design service.
