TUA45S, T-CLASS TM SEPARATED COMBUSTION UNIT HEATERS, TUA75S, TUA100S, TUA60S specifications

Lennox International Inc. stands out as a leader in the heating and cooling industry, and its T-Class™ Separated Combustion Unit Heaters, including models such as TUA60S, TUA100S, TUA125S, and TUA45S, epitomize innovation and efficiency. These unit heaters are engineered to provide reliable warmth in commercial and industrial environments, ensuring comfort and productivity even in the coldest conditions.

One of the most significant features of the T-Class™ heaters is their separated combustion design. This technology allows the heater to draw air for combustion from outside the building, which means that interior air remains untouched and is not used for heating. This design not only improves indoor air quality but also enhances energy efficiency by minimizing heat loss.

The TUA60S, with a heating capacity of 60,000 BTUs, is ideal for smaller spaces, while the TUA100S provides a robust 100,000 BTUs, making it suitable for medium-sized areas. For larger installations, the TUA125S delivers a powerful 125,000 BTUs, ensuring even the most expansive environments remain comfortably warm. Lastly, the TUA45S is perfect for smaller facilities or specific zones requiring efficient heating solutions.

These heaters are equipped with advanced technology such as modulating burners that adjust the heat output based on the current temperature needs, leading to energy savings and reduced operational costs. The T-Class™ units are designed with reliable components, ensuring longevity and reducing maintenance requirements. Additionally, the exterior reflects a modern and durable finish, ensuring they withstand the rigors of industrial settings.

Installation is straightforward thanks to their flexible configurations, allowing for both vertical and horizontal venting options. This adaptability makes them suitable for various applications, from warehouses to manufacturing plants.

In terms of safety, Lennox emphasizes top-tier mechanisms, including built-in safety limits and high-temperature shutoff features to prevent overheating.
