The FXVT range of closed circuit cooling towers are forced draft, combined flow and axial fan towers.
Key benefits include outstanding energy efficiency, easy maintenance and inspection, and guaranteed optimal performance.
Typical applications for this range of cooling towers are HVAC and medium to large industrial applications such as electric arc furnaces and pharmaceutical plants.
Description
High energy efficiency
- Evaporative cooling PLUS of FXVT cooling towers includes a combined heat transfer system for low energy consumption of the entire system.
- Axial fans have half the power consumption of the competition, and a single cell has considerable capacity.
- The BACross II fill is configured at the factory for unmatched water/air transfer and minimal pressure drop, guaranteeing optimal cooling tower efficiency.
- The fan motors are highly efficient.
Low maintenance and easy inspection
- Inspection and maintenance of the cooling tower is carried out safely, with unparalleled comfort inside
- FXVT towers have a spacious interior area and easy access for inspection/maintenance.
- The fans are easily accessible from both inside and outside.
- Inspection of the filler and coil is easily done thanks to the removable drip separators.
- The BACross II padding is supported by telescopic supports for easy inspection and cleaning without disassembly.
- Self-cleaning the cold water basin and filling it above the inclined basin to remove dirt and debris.
Optimum performance guaranteed
- The thermal performance of FXVT is tested and certified by CTI and Eurovent.
- Unique and patented heat transfer system: with combined coil - filler flow, suitable for temperature sensitive applications and thermal challenges.
- A single cell has a huge capacity.
- BACross II padding - patented sheet and maximum air/water contact for optimal heat transfer performance.
- Encased in corrosion resistant fiberglass polyester for long life.
Ultra quiet design
- FXVT cooling towers include low-noise axial fans for minimal noise emissions. For even greater sound reduction, Whisper Quiet fans can be chosen.
- Silencers are factory designed, tested and rated and are available on the air inlet side to further reduce operating noise.
- The BACross II filling guides the water smoothly into the pool without splashing noise.
Easy and cheap to install
- FXVS cooling towers are factory built and delivered in multiple sections for larger models to reduce overall size and weight, allowing easy section assembly on site with smaller cranes.
Excellent hygiene control
- FXVT towers are easy to clean and inspect reducing the risk of bacteria (eg Legionella) or biofilm inside the cooling tower.
- Air intake grilles prevent sunlight from entering the tower to prevent biological growth in the tower, filter the air and stop water splashing outside.
- High-efficiency droplet separators prevent water droplets from reaching the air. Their performance is tested and certified by Eurovent.
THE PRINCIPLE OF OPERATION
The hot process fluid (1) circulates on both sides of the tower through coils (2), which are sprayed with water using a spray system (3). In parallel with this water spray, the axial fan (4) blows air (5) over the coils. The fluid (6) inside the coils is cooled by the evaporation process. The process fluid moves from the bottom to the top of the coils because the cooler spray water and air are at the top of the tower. The sprayed water falls into the filler (7) where it is cooled before falling into the water basin (8). The spray pump (9) recirculates the cooled water to the spray system. The warm saturated air (10) leaves the tower through the drop separators (11).
