Cell-Type Counterflow Concrete

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.

• Concrete cooling towers have the longest service life and can be built almost anywhere in the world
• Cell-type cooling towers are built of in-situ cast concrete or pre-cast concrete
• We can supply the complete civil engineering in almost all countries of the world in close co-operation with local affiliates, licensees and other partners

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 or forced through the cooling tower using 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 optimum 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.
