Air Handling Unit
 High-level
ventilation provides a cost effective and efficient method
of ventilation and temperature control in vegetable box stores.
Farm Electronics
design and manufacture Air Handling Units, specifically for
use in vegetable stores where the crop is contained in boxes
or trays, as in potato chitting stores, and where accurate
temperature control and cooling by ambient air is necessary
to maintain the crop in good condition and at the correct
temperature.
The Air Handling
Units are available in model sizes to use fans of increasing
capacity and are approximately suited for 200 tons, 450 tons
and 800 tons of potatoes.
All Air Handling
Units are fitted as standard with motorised louvres for ambient
air intake and internal air recirculation. The intake louvre
blades are insulated with 20mm Styrofoam. The Air Handling
Units are also supplied with an air distribution hood, which
has adjustable outlet vanes to direct the cooling airflow
evenly around the store.
Control of the
package unit is normally by means of a Cropscan electronic
crop temperature control system and several Air Handling Units
can be controlled from one Cropscan. From the main fan starter/control
panel the operator will also have complete manual control
of all the components in the system.
Air Handling Units
are available for 630mm, 800mm and 1000mm diameter axial fans.
These fans provide high air volume at low energy rates and
are ideally suited for ambient air-cooling systems.
Fan capacities
range from 4 cubmtrs/sec to 15 cubmtrs/sec.
For the best possible
operation the fans are individually selected for each store.
3 No PU 104 Ventilation
Units on Ambient
Only System.
Units are positioned High on
stands to allow
Refrigeration to be added
later if required.
