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.
The key benefits of open cooling towers
Very efficient cooling
Low process temperatures
Small footprint design
Patented Baltibond hybrid coating
Low energy consumption
Eurovent certifications
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.
