- Electric utility operates Hi-Vac®
at two of its power plants. Units are used for general cleanup
of fly ash, clinker, and spilled coal. When boilers are shut down
for periodic maintenance, Hi-Vac®s speed removal of fly ash from
penthouse compartments, saving approximately 5000 man hours during
each cleanout.
- Auto foundry's Hi-Vac® has paid for
itself many times over by preventing costly shutdowns on the block
time. Hi-Vac® quickly removes large sand spills along conveyors
and molding lines to keep production going.
- Farm equipment manufacturer uses
a Hi-Vac® in engine block machining operations. Cast iron chips
and dust are sucked up from 20 machining stations through a manifold
system whose inlets are automatically controlled by a sequential
timer.
- Transit authority of a large city
uses two Hi-Vac® mounted on a service car to clean subway system.
Up to 5 hose lines can be used at once to clean station areas
and honey-combed tunnel walls.
- Coal strip mining company installed
Model 220 Hi-Vac®s in its drag lines for control center and transformer
cleanup.
- Farm equipment manufacturer has
installed a total of seven Hi-Vac®s at three of its foundries.
Most are used with manifold systems and at one plant, Hi-Vac® is
moved between manifolds serving the sand pit and shot reclaim
pit.
- 1000 foot ore carrier has two Model
275 Hi-Vac®s in its hold clean up spills around conveyors.
- Glass container manufactuer handles
spilled cullet and glass batch with a Hi-Vac® Model 230. Ability
to get production going after big spills soon repaid company's
investment.
- Alumina processor's Model 250 Hi-Vac®
"paid for itself" in 90 days by salvaging the valuable
material from under aluminum pots.
- High temperature ceramic company
removes and recycles alumina used to back up graphite molds. Material
had been scooped out by hand requiring the use of respirators.
Hi-Vac® 250 connected to a manifold system now serves two molding
areas.
- Major jobbing foundry has purchased
Hi-Vac® for each of its six foundries. Units are used for cleanup
of shot, sand, sea coal, sludge, etc.
- Hi-Vac® T-50 truck unit cleans up
for a chemical firm. In four hours, two men can now clean out
an area that had taken four men a week.
- Secondary smelter had loaded rail
cars with zinc oxide using from end loaders. Dust spilled and
blew throughout neighborhood. Now a Hi-Vac® manifold system powered
by a Model 230 conveys product from storage to rail cars without
dust, product loss, or contamination.
- Coal company handles troublesome
dust from ground and pulverized coal with a Hi-Vac® Model 250.
Material is too light to sweep and floats when wet. Coal is now
vacuumed for use as carbon black.
- Quarry uses Hi-Vac® Model 230 to
vacuum out cloth dust collectors before installing new filter
bags.
- Aluminum processor cleans between
high-amperage buss bars with a Hi-Vac® 220. Cleaning around one
aluminum reduction "pot" had taken two men a full day.
With Hi-Vac®, two men can vacuum up around eight pots a day.
- Glass manufacturer utilizes a Hi-Vac®
Model 250 on production line to empty and refill refractory molds.
- Railroad has installed 6 Hi-Vac®s
at various car-cleaning facilities to vacuum out box cars, hoppers,
etc. before washing. Most are used with manifold systems to clean
out several cars simultaneously. Another Hi-Vac® vacuums up sand
spill at an engine test terminal.
- Giant cement plant uses 14 Hi-Vac®s
to keep cement dust under control. Vacuumed material is easily
reclaimed.
- Automotive foundry reclaims $800
worth of steel shot spilled from shell molds in just 17 minutes.
Hi-Vac® Model 250 vacuums materials from conveyor pits and at transfer
points.
