ABC Ventilation Systems (Canada) is now the exclusive distributor to North American tunneling of wet and dry dedusters for Engart Dust Extractions. Engart has long been the leading supplier of dedusting for coal mines and the partnership with ABC Ventilation will allow greater access to tunneling markets. The Engart line gives ABC Ventilation Systems the ability to provide dedusting units from 1,000 cfm all the way up to 55,000cfm. Using software specific for dedusting, ABC can now assess the dedusting needs based on the data from the jobsite. One of the best features is that the units do not lose any substantial amount of efficiency with increases in dust loading. This completes the offerings of ABC Ventilation Systems, which now can provide a complete package of vane axial fans, flexible ducting, variable speed drives and de-dusting to tunneling customers.

A gas detection system is essential in TBM operations. Pockets of methane or hydrogen sulfide can kill. In view of prior California tunnel disasters, Cal-OSHA beefed up its safety standards by requiring both mining approvals (i.e. underground, MSHA) and NFPA-70 approvals (above-ground, OSHA) for their tunnel gas monitoring. Rel-Tek has decades of experience with both MSHA and OSHA applications. It recently moved into its Safety Technology Facility, sited in Monroeville, Pa., thus consolidating production, service and training for tunnels, alt-fuel transit and mines. Automatic gas sensor calibration is a development by Rel-Tek that involves using the company’s Millennia computer running MagiKal software. This combination controls calibration of all zones of sensors in just a few minutes with no labor cost and with NIST traceability and documentation. The computer even displays sensor health trends for preventive maintenance. This utility saves money while assuring long-term accuracy, safety and reliability. Web: www.rel-tek.com.
