Above and below floor laterals for bulk stores and silos.
  


"MULTIBAR" LEVEL FLOOR VENTILATION LATERAL

  • The "Multibar" Lateral is manufactured from galvanised steel with a louvred top, suitable for all cereals & oilseeds. "Multibar" is produced 2"wide by 3' long. (max width 4 multibars = 8")This system is suitable for drive over by most agricultural vehicles.
  • Laterals should not be spaced further apart than the Grain depth. i.e. grain 8' deep laterals not more than 8' apart.
  • Fans - Portable fans, forward curved centrifugal up to 2.2kw.
    Mobile backward curved centrifugal fans up to 7.5kw, 1 and 3 phase.
    For larger fans see drying section.

 

 

 

DIFFERENTIAL FAN CONTROLLER

What it does:

  • LVC3 checks crop temperature against ambient air temperature.  When the difference exceeds the set value (1-8 C) the unit supplies 230Va.c. power, either to a small single phase fan (<750W), or to a motor control starter (230Va.c. coil) for larger or three-phase motors.
  • Once the controller has started the fan motor, the internal timer will not allow it to switch OFF until the timed period has elapsed and the differential is less than the set value; this is adjustable on internal switches.
  • An optional "FROST" setting is available where the cooling of crops such as potatoes is required.  This prevents the fan running if the ambient air temperature is less than the set value, adjust on internal switches within the enclosure, -2.0 C - 5.5 C in 0.5 C increments.
  • Should and sensor become disconnected from the controller the two front panel indicators will flash as a warning and the system will not power the fan motor, unless set to MANUAL.

 

 

CORRADUCT HALF ROUND ABOVE FLOOR VENTILATION LATERAL

  • Three sizes available with fully perforated or closed top to suit Airflow requirements. 
  • Ideally suitable for large peak loaded stores to provide wide lateral spacings lengthwise in the building.
