TCBBX2/4-450 : TCBBX2/4 – 450 Soler And Palau (S&P) High Pressure Twin Turbo Cased Fan

The TCBBx2/4-450 is a powerhouse in industrial ventilation, engineered by the prestigious Spanish firm Soler & Palau (S&P). Founded in 1951, S&P’s legacy of engineering excellence is reflected in this range of short-cased axial fans. Formerly recognized in the UK market as the Vent-Axia "Turbo Prop" series, these fans are widely regarded as the industry benchmark for combining high-pressure performance with cost-effective operation.

Advanced Dual-Stage Engineering

The standout feature of the TCBBx2/4-450 is its Contra-Rotating System. By utilizing two synchronized, complementary impellers, the fan effectively doubles the static pressure without increasing the air volume. This makes it the ultimate solution for high-resistance ducting systems where standard axial fans often underperform.

Reliability & Build Quality

• Vibration-Free Operation: Each impeller is dynamically balanced to ISO 1940 standards, ensuring a smooth, quiet, and long-lasting service life.
• Superior Corrosion Resistance: Designed for harsh environments, the unit features a rolled steel casing and motor support. It is protected by a dual layer cataphoresis primer and a durable black polyester paint finish, complemented by stainless steel screws.
• External Terminal Box: For maximum convenience during installation, all units feature a pre-wired, IP65-rated junction box (with a PG-11 cable gland) located on the exterior of the casing.

Motor & Electrical Specifications

These fans are built to withstand demanding conditions, featuring high-spec motors designed for versatility:

• Ingress Protection: Rated IP65 (Dust-tight and protected against water jets).
• Heat Resistance: Features Class F insulation and integrated thermal protection.
• Voltage Flexibility: * Single Phase (230V-50Hz): Features variable voltage control and internal capacitors.
• Three Phase (230/400V-50Hz): Fully compatible with inverter control for precise airflow management.
• Extreme Temperatures: Operates reliably in environments ranging from -40°C to +70°C.

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 TCBBx2/4-450 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 TCBBx2/4-500 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.
