Low running costs and faster cooling speed are not always at the top of the specification list when planning the ventilation system for a new grain store. But with increasing ambient temperatures during storage, and larger store designs, effective fast cooling has become more difficult to achieve.
The Martin Lishman FloorVent underfloor ventilation system offers fast, energy saving cooling in a cost-effective package. Utilizing the same high-airflow perforated tube as the company’s popular Pile-Dry Pedestals, FloorVent pedestals are spaced out across the store and use underfloor ducts connected to highly efficient Pile-Dry cooling fans on the exterior of the building to expel hot air to the atmosphere.
Aimed primarily at new store builds, the FloorVent installation process can be completed using standard materials sourced from building merchants, which can greatly reduce installation costs. Retrofitting existing stores is also possible: Martin Lishman recently supplied a FloorVent system for a refurbished 11,000 ton grain store in France.
“Placing fans outside the store allows warm air to discharge directly out of the building so it can be replaced by cool air drawn in through the building’s air intake louvres”, explains Joel Capper, Managing Director of Martin Lishman Ltd. “This removes the possibility of warm air being drawn back into the grain as cooling takes place, and avoids the need for building extraction fans, allowing further savings on installation and energy costs. The addition of our automatic fan control and temperature monitoring systems can increase the efficiency of FloorVent even further”.
The FloorVent duct sections can be replaced with manhole covers, allowing different sections of the building to be used for storage in a flexible manner, and to make loading and unloading easier. Some customers have even used this design feature for cooling different varieties of crop in the same store.
