Rooftop Make-up Air Units (RTU)

rooftop make-up air unit, rtu muaUncover the core of rooftop units with a focus on the Air Handler Unit, a critical component of our modular fan system. This unit is efficient at drawing in outside air. It can handle pressures up to 4″ W.G. and boasts capacities of up to 22,000 CFM. Due to its design, it is straightforward to access from both sides and can be easily adjusted for optimum results.

Also known as a packaged unit, the RTU offers an all-in-one solution that incorporates all its components into a single unit. Despite being located out of sight on the roof, these units play a crucial role in distributing conditioned air throughout the building.

In this article, we’ll take a closer look at how rooftop make-up air units work, their different types, and their pros and cons.

One of the reasons that RTUs are so popular is because they are self-contained, compact, and easy to install.

What are rooftop units or RTU?

Rooftop units (RTUs) are efficient heating and cooling systems atop buildings, providing climate control to designated spaces. Compact and self-contained, they house all necessary components in one unit, connected to ductwork for streamlined airflow, and are designed to withstand diverse weather conditions.

Factors to Consider

There are several important factors to consider when choosing a rooftop unit (RTU) for your HVAC system.

  1. Size: The size of the RTU is a critical factor to consider, as it must be properly sized for the specific space it will be serving. A unit that is too small will not provide adequate heating or cooling, while a unit that is too large will be inefficient and waste energy.
  2. Efficiency: Look for an RTU with a high-efficiency rating, as this can significantly reduce energy costs over time. Units with higher SEER and EER ratings can also qualify for energy rebates or incentives.
  3. Airflow: Consider the amount of airflow needed for the space, as well as the direction and velocity of the air. Proper airflow is essential for maintaining a comfortable and healthy indoor environment.
  4. Zoning capabilities: Some RTUs offer the ability to provide zoned temperature control, which can help reduce energy costs by only conditioning the areas that are in use.
  5. Maintenance requirements: Look for an RTU with easy access to filters and other components for regular maintenance and cleaning. A unit with a longer lifespan and fewer maintenance requirements will also save on long-term costs.
  6. Budget: The cost of the RTU, including installation and ongoing maintenance, is an important factor to consider when making a decision. While an RTU may have a higher upfront cost than other HVAC systems, it may provide long-term cost savings in energy efficiency and maintenance.
  7. Local codes and regulations: Be sure to check local codes and regulations to ensure that the chosen RTU meets all requirements for safety, efficiency, and environmental impact.

Considering these factors will help you choose an RTU that provides efficient and effective heating, cooling, and ventilation for your commercial building.

RTUs are known for their energy efficiency, which is essential for reducing operating costs and maintaining a comfortable indoor environment.
