For Cooling Oilseed Rape — Please specify whether you require pedestals for Oilseed rape when discussing your needs.
Oilseed rape is five times the density of cereals and this should be taken into account in determining layout and airflow

For grain of 20ft+ depth/increased cooling — We can supply pedestals with 2 metre x 450mm bases: please request a quotation. Contact.

450mm Base Polycool Pedestals achieve unrestricted airflow & are the strongest on the UK market!

'CropCool' Differential Temperature Controller
for Pedestal Fans

Don't give Grain storage Insects a Chance!

• Only runs fans when Ambient Air is cooler than the crop
• Save valuable time switching Fans On/Off
• Speed up grain temperature reduction
• Saves 40% electricity on unnecessary fan running (HGCA research)

'CropCool' constantly compares ambient air temperature to your grain temperature, and will use every available opportunity to reduce your grain temperatures(to prevent insects from breeding, following HGCA guidelines).

The system is easy to operate and it is available for single or 3-phase fans.

The AgriSupplyServices single phase CropCool is fully portable.

Full laminated instructions provided.

'CropCool' has been specifically designed to operate up to 2 Pedestal Fans (1.1Kw, 1.5HP each) from a single 13amp plug.

2m Fibreglass Grain Temperature Probe, which makes insertion into the crop much easier is supplied as standard. (Also available as an extra for existing users.)

Extras

Humidity Sensor, to control fans before temperature, should this be needed for certain applications. Please discuss with Agricultural Supply Services.
