Balcke Counterflow FRP -

Cell-type cooling towers consist of one or several rectangular cells. Being the type most frequently built, cell-type cooling towers are widely used in all industry branches.

Fiberglass (FRP) cooling towers consist of fire-retardant, low-maintenance, corrosion-resistant and anti-fouling FRP structures.

Only small cost difference between timber and fiberglass cooling towers, but high durability of fiberglass cooling towers, almost as concrete cooling towers
Short delivery periods.

The water to be cooled trickles through the cooling fill from top to bottom whilst the air is conveyed through the fill from the bottom (counterflow cooling tower).

Cooling is achieved both through evaporation of a small quantity of the water, latent heat being taken from the cooling water flow, and also through transfer of heat from the water to the cooling air by convection.

The required cooling air is drawn through the cooling tower by fans. We are experienced in the design and construction of both the fans and the mechanical equipment to ensure reliable continuous functioning of a cooling tower.

The cooling fill is the most important part of a cooling tower. As a contact surface it has to ensure optimaum heat exchange between water and air. Several types of cooling fills are available for each particular application, such as film packs, trickle grids or blocks, splash grids or splash slats.

Where necessary, reliable operation during cold seasons is ensured by closing down cells or by by-pass operation.

If required, various options of sound attenuation measures can be implemented by installing for example low noise fans, sound attenuation walls, impingement baffles or sound attenuators.
