🏷️ What Is a ClimateMaster DOAS3 - DH13?

This is a Dedicated Outdoor Air System (DOAS) rooftop unit made by ClimateMaster, and specifically, the model DH13 typically indicates ~13 tons of cooling capacity.

🔧 What Does a DOAS Unit Do?

A DOAS (Dedicated Outdoor Air System) is a specialized HVAC unit that:

✅ Brings in 100% fresh outdoor air

Rather than recirculating air like typical HVAC systems, a DOAS:

• Pulls in outside air
• Conditions it (cools, heats, dehumidifies)
• Sends it into the building’s ventilation system

✅ Manages humidity

These systems are often equipped with dehumidification features to ensure incoming air doesn’t make your building sticky or uncomfortable.

✅ Works alongside other HVAC systems

A DOAS doesn’t typically heat/cool your building alone — it complements your main HVAC system by improving indoor air quality (IAQ) and pressurization.

These CLIMATEMASTER air source heat pump units are engineered for energy-efficient climate control in commercial and industrial settings. Whether you’re upgrading an existing HVAC system or outfitting a new space, these units deliver reliable performance year-round, reducing your energy footprint without compromising on comfort.
