- Our Survey Engineers have had a total of over 90 years of LEV surveying experience.
- Our engineers regularly design and project manage the installation of complete LEV systems.
- A full understanding of the design of LEV systems is key in the diagnostic process when systems do not perform as they should.
- Our engineers have specialist knowledge of all filter types, cyclone separators and DSEAR/ATEX regulations.
Our philosophy
Our philosophy is to help our customers comply with current Health and Safety legislation by using the most cost effective methods.
Recommendations
- We give accurate cost effective recommendations on how to improve under performing systems.
- Blockages and filter cleaning can usually be attended to during the course of a survey in order to improve the airflows, rather than give an unsatisfactory report.
- Often modifications to poor ducting, hoods and filter design can increase airflows and effectiveness without resorting to changing filters early or up-rating a fan. This is better for the environment and saves money.
- Filters are only recommended to be changed if they are damaged, have high dust penetration or show a high differential pressure drop after a cleaning cycle.
- We do not always fail a system if a duct velocity is below the recommended minimum. This is because under certain circumstances it is impractical and not necessary to increase the duct velocity. A consultative approach helps to identify these circumstances.
- On one occasion we proved to the HSE by calculation that fume extraction was not required for a particular process. Saving the customer a considerable sum of money.
