FloorVent

Under-floor Ventilation System

Floorvent is

FloorVent under-floor ventilation is a cost-saving cooling system for new floors, new stores, hopper bottomed bins and silos. It combines the benefits of Pile-Dry Pedestals and Fans with the need to make store handling and filling easier.

FloorVent suits deep grain stores where logistics and safety considerations make moving fans between Pedestals difficult.

FloorVent Pedestals are used in the same way as Pile-Dry Pedestals and Pile-Dry Fans with the same spacing and method of use as the P3 Pedestal and F3 fan.

Key Features

Economic – low installation cost per ton and more energy-efficient localised cooling, compared to traditional under-floor systems
Simple – FloorVent units comprise a perforated Pedestal tube with a conical cap to deflect grain during filling. The tube connects to an under-floor duct via a base plate in a recess in the concrete floor. When the store is empty, a man-hole cover placed over the recess leaves the floor totally multi-purpose.
Versatile – suited to very deep grain in stores, bins and silos where logistics and safety considerations make moving fans between Pedestals difficult. They can be fitted into new floors during construction or retro-fitted to existing floors or hopper-bottom bins and silos.

How FloorVent works

Pile-Dry FloorVent under-floor ventilation units comprise a 12” diameter perforated steel Pedestal tube with a conical cap fitted into one end. The cap serves to deflect grain that is poured onto the unit, sometimes from very high conveyor systems.

The tube is fitted to an under-floor duct via a steel base plate connector that fits into a man-hole recess in the concrete floor.

When not in use, the tube and connector plate are removed and a man-hole cover is used to cover the hole and leave the floor totally multi-purpose.

Easier Filling

Less chance that ducts will move during filling. When pushing up or levelling the grain, there is no tube protruding from the grain that could be damaged.

Direct Heat Extraction

Pile-Dry Fans suck heat from the grain and vent it directly outside the building, avoiding the need for building extraction fans – although fresh air intake using our fixed StoreVent louvres is still advisable.

Installing a FloorVent System

Easier and cheaper than traditional under-floor systems
Uses standard building materials, greatly reducing installation cost and time
No reinforced concrete channels or ventilation strips in the floor
Just a simple trench with solid, smooth-walled drainage pipe, back-filled
Concrete floor is laid and skimmed quickly and easily

Choosing FloorVent or Pile-Dry Pedestals?

From an overall cost versus benefit point of view, Pile-Dry Pedestal and Fans is the most cost-effective crop cooling system.

For new floors or new stores, where grain will be stored above 6-7m depth, a FloorVent Pedestal and Fan system provides greater practical benefits when filling the store and handling the fans.

When compared to a traditional under-floor system, FloorVent is the most cost-effective crop cooling system.

Full Details and Specifications

Scope of use

For crops 4.5 – 14m deep. Includes perforated duct, mounting plate, conical end cap and marker pole assembly. Normal spacing 10m apart. Store no deeper than 4.5m for 18%+ grain moistures.

Applications: can be fitted in new concrete floors, retrofitted to old concrete floors and in hopper-bottomed bins and silos. Uses standard building materials below ground level, at a fraction of the cost of traditional under-floor systems. Please ask for further details and examples.

Additional Details

NB: FloorVent Pedestal component measurements are Imperial and are not compatible with metric sized ducts. Metric sizes shown are approximate equivalents to the actual Imperial sizes.

Assembly and installation: Components are simple to assemble and position on the floor. Under-floor and external components should be installed by a competent civil engineering contractor.
