Frequently Asked Questions View all FAQs
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.

Greenhouses

Triangle Engineering offers a range of fans specifically designed to support greenhouse environments, and efficient climate management.

Greenhouses

Greenhouse Fans for Optimal Airflow, Temperature Control, and Plant Health

In greenhouses, maintaining consistent airflow and temperature control is essential for creating ideal growing conditions. Triangle Engineering offers a range of fans specifically designed to support greenhouse environments, delivering reliable air movement and efficient climate management. With fan sizes ranging from 24” to 60” blade diameters and power options from ⅓ HP to 5 HP, our solutions handle the unique challenges of controlled growing spaces, ensuring a healthy environment for plants and crops.

Engineered for Efficiency and Durability

Triangle Engineering’s greenhouse fans are built to withstand the demanding conditions of greenhouse operations. Available with Open Drip Proof (ODP) motors for moderate exposure and Totally Enclosed (TE) motors for high-humidity, dust-prone environments, our fans provide long-lasting performance tailored to your greenhouse’s needs. Choose between belt drive models for quieter operation and precise speed control or direct drive models for efficient power transfer and minimal maintenance.

Comprehensive Fan Solutions for Greenhouses

Maintaining steady airflow is crucial for regulating temperature and humidity levels in a greenhouse. Proper humidity control helps prevent issues such as mold, mildew, and pest buildup, supporting a healthy growing environment. Triangle Engineering’s fans are engineered to deliver consistent airflow at static pressure, making them ideal for enclosed greenhouse spaces. Whether you need products for localized air movement to target specific plant zones or exhaust systems for broad circulation across the entire greenhouse, we have the solutions to fit your needs.

Key Features of Our Greenhouse Fans:

  • Wide Range of Fan Sizes and Power Options: Blade diameters from 24” to 60” and power options from ⅓ HP to 5 HP, delivering high CFM airflow suitable for small to large greenhouses.
  • Motor Options for Varied Conditions: Available with ODP motors for moderate environments and TE motors for high-humidity, dust-prone areas.
  • Belt Drive and Direct Drive Models: Belt drive for quieter operation and slower blade speeds; direct drive for low-maintenance, efficient performance.
  • Consistent Airflow at Static Pressure: Designed for steady airflow in enclosed greenhouse spaces, supporting effective temperature and humidity control.
  • Voltage Configurations: Standard voltage options include 115V 1-phase, 230V 1-phase, 230V 3-phase, and 460V 3-phase, with additional optional voltages such as 277V 1-phase, 208V 3-phase, 415V 3-phase, and 575V 3-phase (contact us for other voltage needs).
  • Shutters and Dampers for Ventilation Control: Standard-size intake/supply and exhaust shutters, with customizable all-aluminum options available in 1/8” increments for a precise fit.
  • Built for Greenhouse Durability: Constructed with high-quality materials to withstand humidity, temperature changes, and continuous use.

Ideal Applications for Greenhouse Fans:

  • Plant and Crop Growing Areas: Ensure consistent airflow to regulate temperature and humidity, promoting healthy plant growth.
  • Propagation Zones: Create the right climate conditions for seed germination and young plant development.
  • Moisture Control: Reduce humidity levels to prevent mold, mildew, and other issues that can harm crops.
  • General Greenhouse Ventilation: Support overall temperature management and air circulation for larger greenhouse spaces.
  • Strengthening Plants and Stalks: Encourage robust plant and stalk development by maintaining consistent airflow, which mimics natural wind movement.

Enhance Ventilation Control with Shutters and Dampers

To further optimize airflow and ventilation in greenhouses, Triangle Engineering offers a variety of intake/supply and exhaust shutters in standard sizes, as well as custom all-aluminum shutters crafted to order in 1/8” increments for a perfect fit. For operations requiring advanced control, motorized shutters are available to provide precise, automated airflow management. These solutions help maintain effective temperature and humidity levels, creating a balanced and productive growing environment.

Custom Solutions for Unique Greenhouse Needs

Triangle Engineering understands that no two greenhouses are the same. We offer custom fan and shutter solutions to meet specific requirements for airflow and environmental control. Proudly made in the USA with a blend of domestic and imported components, our fans are built for reliability and performance, and each unit is factory-tested to ensure it meets our high standards.
