A 3 Ton RTU (Roof Top Unit) is a type of air conditioning system that is designed to be mounted on the roof of a building. It is typically used in commercial applications, such as office buildings, retail stores, and restaurants. The 3 Ton RTU is designed to provide a high level of cooling and air circulation in a large area. It is usually composed of a compressor, condenser, evaporator, and other components. The 3 Ton RTU is capable of cooling up to 3 tons of air per hour, which is enough to cool a large space. It is also more energy efficient than other types of air conditioning systems, making it a great choice for businesses looking to save money on their energy bills. The 3 Ton RTU is also relatively easy to install and maintain, making it a great choice for businesses that don’t have the time or resources to invest in a more complex air conditioning system.
