3ph Crop Cool Multi Fan Hub: 6 x 1.1kw
Enclosure with 32 Amp supply socket ready to plug directly into farmer's 3ph supply.
Facility to plug in 6 fans via 16amp panel mounted sockets. Hub will switch fans on when RUN signal is received from Crop Cool Controller.
Hub contains all necessary protection for motors, Contactors and conductors. Additional timer fitted so that fans are switched on in 3 stages.
- Hub requires a 32amp 3ph supply
- Will automate between two and eight 1.1kw or 2.2kw grain cooling fans
- Differential temperature control switches fans on and off when ambient conditions allow for efficient grain cooling
- Able to handle up to five grain temperature inputs
- Hubs integral timers switch fans on in stages so supply is not overloaded
- Hub contains breakers and overloads to protect cables and motors
- Saves money and time by removing the need for an electrical contractor to design and build a bespoke system to automate fans
The big benefit of all three of these systems is that they provide a low-cost option for automation. Fans are only running when the conditions for cooling are optimal. In a conventional situation, fans will often be switched on as a matter of course in the evening and switched off in the morning regardless. This takes no account of ambient air temperatures and the fact that air blown through the heap may actually increase grain temperatures if above the required differential. Aside from unnecessary energy usage, this can also put crop quality at risk with higher crop temperatures increasing insect pest activity.
