The patented intelligent flow control system with a 3-way valve allows precise control of the outlet liquid temperature and annual water savings.
Operating program that adapts to operation in dry mode, in adiabatic mode or combined wet/dry mode.
Compact
Side by side installation for two cell towers. Access to the water basin is at the end of the tower connection.
Very low height, fits perfectly on roofs or in narrow spaces.
Low operating weight. The water basin contains only 1/4 of the water required for conventional cooling towers.
Excellent hygiene control
Operation in dry mode for 10 months a year is possible depending on the type of application and the weather.
Self-cleaning tank and drainage to prevent stagnant water.
The water basin is placed outside the air stream and is accessible during operation.
Low noise
Low-noise centrifugal fans for a quieter environment.
The air intake is carried out on one side, the cooling towers can be located in areas more sensitive to noise.
Easy to install
Air intake on one side allows towers to be installed next to solid walls.
Units that can be placed indoors thanks to centrifugal fans
Year-round reliable operation
During dry operation in winter it is not necessary to empty the pool. Placing the water basin out of the air stream and the heating elements prevent the water in the basin from freezing even when the fans are running at full speed.
Mist-free wet operation thanks to optional finned coil that reduces the humidity of the air rejected through the coil.
Different corrosion-resistant materials are available, including Baltibond, a patented hybrid coating, to guarantee a long service life.
Operating principle
Dry operation
The sprinkler water pump (1) and spray system (2) are stopped and the flow control valve (3-way valve) (3) remains fully open. Hot process fluid (4) flows through both the finned coil (5) at the top of the cooling tower and the coil at the bottom of the tower (6). The fan (7) blows ambient air (8) over the coil and cools the fluid (9) inside it. In this way, there is no water consumption, and there is no fog.
Adiabatic operation
The flow control valve (3-way valve) (1) allows hot process fluid (2) to flow through the finned coil (3), also passing through the primary coil, at the bottom of the tower (4). The coil is wetted by the sprayed water (5), but there is no evaporation of the water to release heat. The fan (7) blows air over the coil, and some of the water will evaporate, which will moisten the ambient air (6). This saturated air has a better cooling capacity of the process fluid (8) in the finned coil. The sprayed water falls into a basin with an inclined bottom (9) and drains into the cold water basin (10). The pump recirculates the water to the spray system. Visible mist and water consumption are greatly reduced, if the fluid outlet temperature is maintained according to the design data.
Wet-dry operation
Hot process fluid (1) flows through both the finned coil (2) and the primary coil at the bottom of the tower (3). The fan (4) blows the air (5) over the coil. At the top where the hot fluid enters the tower, the discharge air is saturated and already pre-cools the fluid. Then, in the primary coil, which is wetted by the spray system (6), the following heat transfer process takes place. The sprayed water falls into a basin with an inclined bottom (7) and drains into the cold water basin (8). The pump recirculates the water to the spray system. When there is a lower heat load or the ambient temperature drops, the 3-way valve (9) will control the flow through the coil so that the outlet fluid temperature is maintained within design parameters. Fog is also minimized because there is less water evaporated and the discharge air is heated using the finned coil.
