“It’s flexible enough that no matter what climate you are in or what your ventilation objectives and requirements are — you can do it with this system,” says Gorman Controls vice-president Duane Gorman.
The system has several features that provide a fully customized operation:
- Demand ventilation, based on temperature and/or carbon dioxide, allows a storage manager to optimize ventilation time. The feature matches ventilation time with the crop requirements while minimizing shrink, pressure bruise, and energy consumption.
- Pile sensor averaging allows users to monitor temperature throughout the system. Storage managers can use this tool to control ventilation time based on any combination of these sensors using the maximum, minimum, or average value of these temperatures. The manager can also use these sensors to maintain uniform temperatures throughout the crop.
- Fan speed control provides even more flexibility. The fan speed can be automatically controlled depending on the objective of a given ventilation time. If a user is cooling a crop they can operate the fans at full speed, however, if the objective is circulating air to provide a uniform temperature, the full capacity of the fans may not be required. During these periods, the fans can be automatically operated at a lower speed, thereby minimizing energy consumption.
