before
after

Dustop™ systems provide dust suppression in grain storage facilities, feed mills, fertilizer plants, rice mills, and processing plants using a digital monitoring system for the accurate and controlled application of mineral oil.

Advantages of Dustop Systems

  • Efficient airborne dust reduction
  • Single-, double-, or triple-point distribution
  • Cost effective parts and labor
  • Easy assembly and installation
  • Automatic start and stop

How Dust Suppression Helps You

  • Cleaner facilities
  • Improved functioning
  • Improved moral
  • Reduced shrink loss

FDA regulations allow an application rate of .02% by volume. We recommend using a gallon for every 1,000 bushels of grain.

Typical Dustop™ Components

DIGITAL AMMETER WITH RELAY CARD
The motor on the conveyor or elevator leg to be sprayed is
monitored for amp draw when empty. When the material flow
increases the amp draw, the relay trips and starts the spray of oil. As
the flow stops, the amp draw drops below the preset and the flow
of oil stops.

SYSTEM CABINET
The cabinet dimensions are: 30" wide x 17" deep x 21" tall. The
motor is a ½ HP TEFC motor. (Class II G available).

MECHANICAL FLOW METER
Measures the gallon per minute flow to ensure proper flow rate.
Mounts on each discharge on the main unit. 1/4" NPT fittings.
(4/20mA digital output is available).

SOLENOID (CLASS II GROUP G)
Located near the spray point, the solenoid opens or closes to
control the oil flow to each outlet. 1/2" NPT fittings.

SPRAY LANCE ASSEMBLY
Includes mounting bracket, check valve, nozzle, 36” hose and one
inline strainer.

SPRAY POINT HEATERS
Necessary when spraying vegetable oil (or high viscosity oil) in
colder climates. NEMA 4/7 1 or 3 phase. 1/2" NPT fittings.
