Cut waste and pollution
Collect & Convey Dust Reclamation Systems prevent the loss of valuable cementitious material by capturing fugitive dust from silo filling operations and automatically returning it to the source silo. Each system requires, on average, 20-30 cu. ft. of air usage per convey cycle and 5-15 scfm of clean, dry air for filter cleaning. The system can be easily integrated with plant wiring with its automatic onboard controls to reduce electrical energy costs. Cyclonaire Corp. 800-445-0730. www.cyclonaire.com.

Low NOx Engine Solution
MP7 and MP8 engines have been certified to meet California's 2008 criteria to limit nitrogen oxide (NOx) emissions while idling. Producers operating trucks with compliant engines won't have to shut down their engines after five minutes of idling as California regulations which took effect earlier this year require. Fleet managers can specify “Idle Emission Certification – Carb 08” for MP Series engines built after Jan. 1, 2008. This feature means the truck's engine has been certified to meet the 30-gram/hr NOx limit. Mack Trucks Inc. 800-866-1177. www.macktrucks.com.
