We take this opportunity in stating that BELL COOLING TOWERS are unique by being the only Forced Draught Fibreglass Cooling Towers with a complete range. It has the following distinct advantages over any other Induced Draught Tower:-

ECONOMY IN POWER CONSUMPTION:- Being forced draught, the fan handles cold and dry air with much less specific volume and hence air flow quantity is lesser, for a given duty, than Induced Draught. Also BELL uses specially designed PVC fills which has lesser static resistance than any other type of fills. And finally the velocity pressure which is wasted into the atmosphere in Induced Draught towers, is utilized effectively in Forced Draught towers contributing in saving of power. 

ECONOMY IN WATER CONSUMPTION:- As the exit air velocity is less in a Forced Draught tower, the carry over loss is reduced. Coupled with this, very high efficiency drift eliminators reduce the total drift loss to max. 0.05% compared with 0.2 - 0.3% for other type of towers. This also eliminates the drift nuisance as well as algae formation around the towers.

ECONOMY IN SPACE CONSUMPTION:- As the air entry to the cooling tower is from one side and discharge is from the top of the cooling tower, the clearance required for forced draught towers is only from one side, whereas for Induced Draught towers, clearance from all the sides of the cooling towers needed, effectively requiring more space.

EASY MAINTENANCE:- Over and above the preceding points, the forced draught tower has moving parts near the foundation increasing stability and life. The fan handles dry, air, therefore the problem of corrosion is reduced considerably and moisture - condensation, motor burnouts are also eliminated. Maintenance is easier as the fan is near the ground and easily accessible. The top of the tower is open, hence internals are also easily accessible.

TECHNICALLY SUPERIOR TOWER INTERNALS:

Coupled with this, BELL has an unpressurised gravity flow distribution system requiring minimum of maintenance, eliminating the possibilities of breakdowns due to clogging of nozzles or sprinkler holes.

All PVC Fills are double folded with an automatic drainage system, producing a favourable pressure drop and a good protection against erosion. They are glued by automatic process and manufactured with German Technology. The fills can easily withstand temperature upto 65 C. High Efficiency Drift Eliminators manufactured with German design ensure a maximum drift loss of 0.05% under standard design conditions. The sub-distribution pipes are made of rigid PVC with a testing - pressure of 6 Kg/cm2.

LONG LASTING EXTERNAL PANELS:

The cooling tower panels and main troughs are of corrosion resistant fibreglass with a longer service life and available in various colour choices. BELL uses superior quality isothelic resin and FRP matting, making the components stronger for withstanding wind pressures.

ESPECIALLY DESIGNED FANS & STANDARD MOTORS:

The Axial Flow Fans are statically balanced and manufactured in strick conformation to renowned American Designs. All motors are of standard make TEFC, with IP 55 protection and co-guaranteed by the original Manufacturers such as SIEMENS, NGEF, ABB, KIRLOSKAR and others. All the fans are direct driven, eliminating any gear box problems as experienced in other cooling towers.

TWIN FANS & MOTORS:

Moreover, in the higher range of towers of capacities of 175 TR and above, BELL supplies them with twin / multiple fans & motors enabling you to further save on power, if the plant operates on partial load. In case of hospitals, hotels etc. where there is a 24 hours operation, any changes of breakdown is eliminated because the plant can still be run on part load. Periodic servicing can be carried out without any shutdowns.

All the above features make BELL COOLING TOWERS give HIGHER THERMO DYNAMIC EFFICIENCY benefiting the user in several ways and saving in running costs.
