Pedestals 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.

Rape Skirts (filters) are available made from strong hessian.

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

AgriSupplyServices is the UK's foremost distributor of Polycool Grain Pedestals and Crop Pedestals.

Tough Enough?

Tests conclusively prove airflow through Standard Polycool Pedestals is not restricted when used with a standard 1.1Kw Fan, such as the VBW7.

From our extensive research & farmer experience we ONLY supply Green ‘Virgin Plastic’ PolyCool Pedestals, we do NOT supply Black Recycled Plastic Pedestals which are a different specification.

For ventilation control and monitoring see our CropCool™ and CropCool™ Wireless products.

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.

Hydor HVSS Ventilation Sock System

Hydor HVSS Ventialation Sock System

Hydor’s Ventilation Sock System supplies fresh
air to all parts of the building to dilute airborne
pathogens and irritants. This system is particularly
suitable for livestock buildings.

Extending through the length of the shed above animal
height the system provides a constant, positive supply of
fresh air to the animal’s immediate location, diluting foul
air and ensuring even temperatures irrespective of outside
weather conditions.

Dust, cobwebs, condensation, humid atmosphere and
damp beds are all a precursor to disease and health
problems, furthermore a lack of adequate ventilation
leads to a build up of ammonia and micro-organisms. The
Ventilation Sock System has been proven to reduce cases
of pneumonia in livestock as a result of damp and humid air
conditions.

Features and Benefits

  • Positive air movement regardless of external weather
    conditions and wind speeds
  • Air distribution to the animals immediate environment
  • Reduced cases of disease and health problems due to
    improved air quality and even temperature
  • Simple installation
  • Low running costs
  • Up to 100ft sock with holes positioned according to a
    customer’s requirements
