Falk CTA Gear Drive for Cooling Towers
The Falk CTA Gear Drive is a right-angle gearing solution designed specifically for the extreme rigors of cooling towers. As a direct replacement for Amarillo® models, the CTA type facilitates a quick upgrade without modifying the existing base. It stands out for its double-reduction design, high-precision spiral bevel gears, and a robust housing with vertical fins that maximize thermal dissipation.
Note: Amarillo® is believed to be the trademark and/or trade name of Amarillo Gear Company LLC and is not owned or controlled by Regal Rexnord™ Corporation or its affiliates.
- Critical dimensions compatible with Amarillo® models (1110, 1311, 1712, 1713) for a hassle-free installation.
- Triple protection: Double radial lip seals and labyrinth rings protect bearings against water contamination.
- Corrosion resistance: Standard marine-grade paint coating (ISO 12944-5 C5-M) for maximum durability in humid environments.
- Thermal optimization: Cast iron housing with vertical fins that improve natural air convection.
- Precision gearing: State-of-the-art hard-cut spiral bevel gears to reduce noise and vibration.
- Pump-less lubrication: Oil management system using an oil slinger that ensures lubrication at all points without additional mechanical components.
- Extended service life: Bearings selected to exceed 100,000 L10 life hours (per AGMA/CTI standards).
- Power ratings: From 100 HP up to 390 HP (at a 2.0 Service Factor).
- Transmission ratios: 19 standard ratios ranging from 7.5:1 to 20:1.
The series is defined by unit size and torque capacity. The main models are:
- Size 2255: Interchangeable with Amarillo 1110.
- Size 2275: Interchangeable with Amarillo 1311.
- Size 2310: Interchangeable with Amarillo 1712.
- Size 2350: Interchangeable with Amarillo 1713.
Integrated Cooling Tower Solution
This product is a key component of the Regal Rexnord power train system, specifically engineered to maximize reliability in critical operating environments. For superior performance, this equipment integrates into a complete drive system along with Falk CTA gear drives, Addax carbon fiber couplings, Addax mechanical brakes, and Cambridge water screens. Together, these components form a robust solution that eliminates corrosion issues and reduces maintenance costs.
