BAC Open cooling towers

Baltimore Aircoil Company (BAC) is the world’s largest manufacturer of cooling towers. With over 75 years of experience and over 100 patents in the field, BAC offers reliable and efficient cooling technologies for industrial, HVAC and refrigeration processes.

Open cooling towers discharge heat from water-cooled systems into the atmosphere. The hot process water is distributed over a fill pack (heat transfer media) to interface with air blown by a fan through the cooling tower. During this evaporative cooling, a small part of the water evaporates while cooling the remaining process water.

VTO/1
Cooling tower

Overview

Reliable operation guaranteed

Since 1978, thousands globally installed, proving the VT0/1-previously called VXT- cooling tower reliability.

Fans, motor and drive system (V-belt) are located in the dry air, preventing moisture and condensation.  No external moving parts, helping it withstand the toughest weather.

The thermal performance of VT0/1 cooling towers is tested and certified by Eurovent.

Various corrosion-resistant materials, including the unique Baltibond hybrid coating for guaranteed long service life.


Ideal for a quiet operation

VT0/1 units include quiet internal centrifugal fans for minimal surrounding noise.

Single-side air inlet, and a quieter tower rear for more noise-sensitive areas.

Cut operation noise still further with factory-designed and tested sound attenuators or silencers.


More compact

Compact design for confined spaces.
Single-side air inlet lets you install next to solid walls.

Units housable indoors thanks to centrifugal fans allowing intake or discharge ductwork.


Reduced shipping, rigging and installation costs

VT0/1 towers are factory-assembled. We ship larger models in 2 sections to reduce the size and weight of the heaviest section for easy on-site assembly with smaller cranes.

VT0/1 offers high capacity and minimal operating weight. Save on steel supports, both underneath the equipment and in the building itself for rooftop installations.

VT0/1 towers can be container-shipped (in 12’ containers). Fan enclosures shippable loose in the tower bottom section for easy on-site assembly.


Easy to maintain

Easy access to all the mechanicals, including fan shaft bearings.

BACount individual bundled fill sheets for easy and complete inspection or cleaning preventing full replacement of fill bundles.

Principle of Operation

Warm process water (1) from the heat source enters the spray 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 centrifugal fan (4) of the air movement system, located at the bottom of the cooling tower, blows ambient air (5) upwards through the tower. While the warm process water contacts the cold air the latter heats up and part of the process water is evaporated resulting in an optimal heat transfer. The tower sump (6) or basin collects the cooled water (7) after which it returns to the heat source of the process. The warm saturated air (8) leaves the tower through the drift eliminators (9), which remove water droplets from the air.

Principle of Operation

Warm process water (3) from the heat source enters the water distribution system (8) at the top of the cooling tower where it is distributed over the fill or heat transfer media (6). At the same time axial fans, located at the top of the unit, draw the air (1) from the side of the unit over the fill. Combined inlet shields 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 (4). The warm saturated air (2) first passes through the drift eliminators (9), which remove water droplets from the air, and then exits the tower at the top.
