TCBBX2/4-560 : TCBBX2/4 – 560 Soler And Palau (S&P) High Pressure Twin Turbo Cased Fan

The TCBBx2/4-560 is the high-capacity solution within the renowned Soler & Palau (S&P) short-cased axial range. Engineered for maximum air volume and aggressive static pressure, this 560mm diameter unit is a direct evolution of the classic Vent-Axia "Turbo Prop" design. Since 1951, S&P has set the standard for durability, and the 560 model is built to handle the most demanding commercial and industrial ducting environments.

The Power of Contra-Rotating Technology

The core of the TCBBx2/4-560’s performance is its two-stage contra-rotating impeller system. By utilizing two high-torque impellers spinning in opposite directions, the fan doubles the pressure development compared to single-stage units. This makes the 560-model ideal for systems where heavy filtration, dampers, or long duct runs create significant resistance.

Industrial Build & Corrosion Protection

• Precision Engineering: Both impellers are dynamically balanced to ISO 1940 standards, ensuring smooth, vibration-free operation even at peak speeds.
• Double-Layer Protection: The rolled steel casing and motor supports are treated with a cataphoresis primer and finished with a robust black polyester paint. Combined with stainless steel hardware, this fan is built to resist corrosion in high-moisture or outdoor environments.
• External Terminal Interface: Installation is simplified with a pre-wired, IP65-rated terminal box mounted on the exterior of the casing, featuring a PG-11 cable gland for quick and secure electrical connection.

Motor & Electrical Capabilities

Designed for continuous heavy-duty use, the TCBBx2/4-560 features premium motor specifications:

• Heavy-Duty Rating: Fully IP65 rated (dust-tight and water-jet resistant) with Class F insulation.
• Thermal Management: Integrated thermal protection ensures the motor remains safe during high-load periods.
• Versatile Control Options: TCBBx2 (Single Phase 230V): Fully variable via voltage control.
• TCBTx2 (Three Phase 400V): Optimized for inverter/VFD control for precise air management.
• Extreme Performance Range: Engineered to operate flawlessly in temperatures from -40°C up to +70°C.

TCBBx2 Dimensional Specifications (mm)

The table below details the physical dimensions for the short-cased axial fan series. These measurements are essential for ensuring proper fitment within your ducting system and for preparing mounting brackets.

Why Choose the TCBBx2/4-560 for Industrial Use?

1. Superior Pressure Development

Standard axial fans often struggle with system resistance. The "Turbo Prop" design provides a steep pressure curve, allowing it to push air through filters, dampers, and complex ducting where other fans would stall.

2. Flexible Electrical Configurations

Whether your site requires Single Phase (230V-50Hz) with an integrated capacitor or Three Phase (400V) for inverter-driven speed control, the TCBBx2/4-560 range offers a solution for every power requirement.

3. Compact Short-Cased Design

The short cased housing allows for high-power ventilation in tight spaces, making it ideal for commercial kitchen extraction, warehouse cooling, and industrial drying plants.
