Rooftop Systems
At O2 Cool Manufacturing, we specialize in high-quality evaporators designed for rooftop motor vehicle HVAC systems. These units typically feature all-in-one configurations that sit on top of the vehicle, drawing air directly from the cabin, which minimizes the need for extensive ductwork and significant vehicle modifications. Cooled air is returned to the cabin through the same air handling apparatus.

What Are Rooftop System Evaporators?
Rooftop evaporators are housed within durable casings that integrate with the vehicle’s exterior appearance, usually sleek and low-profile to reduce drag. The core consists of finned tubes and specially designed coils that absorb heat from the air passing through. In many systems, the housing also includes critical components like the condenser, and at times the compressor. This also means that they lose less energy and refrigerant than other setups where the components are more spread out.
Rooftop evaporators are easier to install as you don’t need to run ducts and electrical connections through the vehicle. Support bracketry is also available when rooftop structure is a concern. They are also easier to access for maintenance since all the components are in one place, compared to internally mounted systems.
What Are the Benefits of Rooftop Evaporators?
Rooftop HVAC system evaporators from O2 Cool Manufacturing offer numerous benefits, including:
- Efficient cooling: Our designs provide enhanced performance for optimal comfort.
- Better temperature control: We tailor climate management solutions to meet specific needs.
- Minimal cabin intrusion: Our systems maximize interior space for passengers and cargo.
- Improved airflow: Ensures even distribution of cool air throughout the cabin.
- Reduced cabin condensation: Minimizes moisture build-up, creating a drier environment.
Our rooftop system evaporators are also versatile, and we offer customization options to suit a variety of commercial, heavy-duty, and specialty vehicles, making them ideal for a wide range of applications.
What Types of Vehicles Use Rooftop Evaporators?
Certain vehicles favor rooftop evaporators because they deliver high-powered cooling while optimizing the usable space inside the cabin. They also provide flexibility in design, accommodating various needs without interfering with other systems or functionalities:
- Emergency Response Vehicles: Precise temperature control for patients and equipment
- School Buses: Uniform cooling while maximizing seat and storage space
- Commercial Trucks: Fuel consumption elimination during long stops
- Agricultural Equipment: Comfort in extreme temperatures without obstructing workspace
Additionally, the robust construction of our rooftop systems protects them from dirt, debris, and potential damage, ensuring longevity.
