How do you order the correct replacement parts?

Before ordering replacement parts, make sure you have the fan model and serial number.

Where can I find instructions to wire a motor on my fan?

The nameplate of the motor includes a wiring diagram. Wiring diagrams can also be found beneath the motor image in our Buy Parts section. Simply click the wiring diagram icon to view it.

Can I install a thermostat?

Yes, but only if the thermostat has a simple on/off operation. Please note: if the thermostat varies the amount of voltage delivered, it will damage the motor and void the warranty.

Can I install my whole house fan vertically?

Comfort Cooler (CC) series whole-house fans may be mounted vertically, however, the AS and CSS shutters will not function properly in the vertical position. We do not carry a ceiling shutter for vertical installation. Vertical installation instructions.

Agri-Control Technologies & Triangle Engineering

A vegetable of note, the sweet potato, requires ample time to ripen to allow starches to convert to sugar. This ripening process requires dry storage in a well-ventilated place where the temperature is monitored and controlled. In some instances, sweet potatoes may be stored for up to one year in the commercial vegetable industry— that is where Agri-Control Technologies comes into scope.

Energy Efficient Vegetable Storage Ventilation

For over 25 years, Agri-Control Technologies has been the front-runner in the vegetable industry and the air ventilation world. Energy efficiency is an industry must and Agri-Control Technologies knows the ins and outs. Parent company BTU Ventilation offers low energy consumption E-Coolers that are maintenance-free with a long life. BTU Ventilation has combined today’s technology with time-proven practices to become the leader in vegetable storage ventilation, and they are also putting that to use for the emerging beekeeping industry. 

Triangle Engineering’s equipment has been used for many years by sweet potato growers. Their availability is good, especially for last minute orders, due to their ample stock. Recently, we’ve also see the same or similar ventilation equipment used by beekeepers as a vital part of smart bee storage systems to protect pollinators in the winter.
