Walgren will feature a new “green” hoist designed to reduce exhausted air by as much as 50 percent and increase fume capture. The exhausted air is based in the open area above the tank with the cover. The hoist is completely enclosed and offers a push blower option. A combination of variable-frequency drives and dampers enables higher exhaust rates when the cover is removed.
Other features of the hoist include a low profile, accessible motors and gearboxes for maintenance ease, and a drip pan that eliminates dragout.
