Tall Boy Induction Unit


Everything you need to know about the Tall Boy Induction Unit (TBY)

A tall boy induction unit is installed in taller locations where the width is less. Enclosures with more height generally use tall boy systems to fit in the location. They are the preferred air management solutions for replacement projects in industrial spaces. Today, most buildings with a lack of space and wide-area utilize the tallboy units for their heating and cooling needs.

They are made with 3 to 4-inch standard round transitions, which easily fit most currents. These units have a height of 17-inches and a width of 7 ⅛ inches. The tall boy units have a heating capacity of 1,400 to 4,500 BTUH and a cooling capacity of 2,900 – 6,800 BTUH. Their primary airflow is 15 to 70 CFM. These induction units provide superior cooling in the space they are installed even though they are kept in a tall enclosure.

In this article, we will highlight the installation of tall boy induction units. We will also see their application and maintenance information. Sometimes known as a slimline induction unit, tall boy systems are perfect for upgrading the existing induction unit. If you want to save some space with induction units, then tall boy is the answer.


Tallboy induction unit Installation

EB Air Tall Boy Induction Unit (TBY) installation process requires understanding the space first. You must ensure that you have enough area to install the induction unit. Also, check the label to ensure that the right induction unit is being installed at the location.

The next step is to identify the orientation of the air and the water connections. This will help to figure out which air should flow from the induction unit. The piping and duct connections would require appropriate space.

Tall boy units are one of those air management solutions that require proper maintenance. You must check that space has enough room to remove the lint screen during maintenance. You must have ample clearance for that, otherwise, maintenance would become difficult.

The return air path must not restrict the airflow. It will defeat the whole purpose of installing the induction unit system.

The last and the most important step is to install the tallboy induction unit within the enclosure through brackets and wall hangers. The unit’s air discharge must meet the supply air grille when any gaps or openings, otherwise there will be chances of air leaks from the induction unit. Once the installation is done, check that the system is firmly fixed in the enclosure without any shakiness.


Tall Boy Induction Unit Application

The biggest advantage of replacing the existing induction unit with a tall boy is to achieve a significant reduction in noise levels. The older systems produce high noise and may not have been installed in enough space. The reduced fan operation pressures and smooth airflow from the nozzles minimize the noise levels by 5 to 15 NC.

Apart from that, a slimline induction unit is beneficial in increasing the cooling capacity. The new induction units can be easily scaled to maximize the cooling capacity while keeping the operating pressure static and the same levels of noise.

Most tall boy air management solutions are used by commercial and industrial spaces that have heavy requirements for cooling and heating large spaces. Hospitals, government buildings, institutions, manufacturing units, commercial spaces, laboratories, schools & colleges, etc. need induction units to monitor and regulate the temperature in the area.

It is important to inspect the secondary water coil, nozzles, and lint screen at regular intervals to ensure that the induction unit is performing well. Wipe the air grille with a dust cloth and clean the lint screen to keep the induction unit in a good condition.
