The use of high strength Pultruded Composite components for the primary structure combined with B.A.C.’s patented Bonded Panel to Post Connection offers many advantages over conventional hand laid or chopped strand fibreglass construction methods. Pultruded composites possess a superior strength to weight ratio of up to five times that of chopped strand fibreglass.
The large access panel is fitted with easily removable knobs. Removing the access panel does not require any tools or dismantling of the unit structure, providing unparalleled access to all of the internal components for inspection, cleaning and maintenance.
The product has been designed to be highly configurable to make installation easier. The ability to select motor and connection locations saves installation piping and wiring costs.
Removal of the louvres, requiring no tools, provides access to all sides of the smooth faced cold water basin for inspection, cleaning and maintenance.
High level build materials along with exceptional design standards assist in creating a highly reliable and consistent product.
Reduced height design, allowing for placement in spaces where other product would become more visible.
Warm process water (1) from the heat source enters thespray system (2) at the top of the cooling tower where it is distributed over the fill or heat transfer media (3). At the same time the axial fan (4), located at the top of the unit, draws the air from the sides of the unit (5) over the fill. Combined inlet shields (6) protect the tower from debris being drawn into the unit. While the warm process water contacts the cold air the latter heats up and part of the process water is evaporated which removes the heat from the remaining water. The sloping sump (7)or basin collects the cooled water after which it returns to the heat source of the process (8). The warm saturated air (9) first passes through the drift eliminators (10), which remove water droplets from the air, and then exits the tower at the top.
