R32 DC Inverter Rooftop Package Unit

15 SEER2 & 18 SEER2 Packaged Heat Pump Solutions

Integrated cooling, heating, air circulation and filtration with DC inverter technology and R32 refrigerant.

R32 DC inverter rooftop packaged HVAC unit for residential and commercial heating and cooling applications.

High Energy Efficiency

The rooftop package unit is available in high-efficiency configurations including 15 SEER2 and 18 SEER2 models, with selected configurations reaching up to 19 SEER2.

DC inverter compressor control allows system capacity to adjust according to the actual cooling or heating load instead of operating continuously at full output.

R32 Refrigerant

The system uses R32 refrigerant as part of its high-efficiency refrigeration platform.

R32 is increasingly used in modern air-conditioning and heat pump equipment for applicable international markets.

Quiet Operation

ECM outdoor fan and blower motors help provide smoother airflow and lower operating noise.

Because the refrigeration and air-moving equipment is installed outdoors, indoor areas primarily require the supply and return duct system, helping reduce indoor mechanical noise and save usable space.

Horizontal & Downflow Installation

The rooftop package unit supports both horizontal and downflow air-distribution configurations, allowing it to adapt to different building layouts.

A universal curb design can also help simplify installation and selected rooftop replacement applications.

Reliable Outdoor Design

The rooftop cabinet is designed for outdoor installation with weather-resistant construction, insulation and sealing to protect major internal components.

A dedicated electrical control section helps reduce exposure of control components to moisture and roof leakage.

Dehumidification Performance

Direct evaporative cooling allows the conditioned air to pass directly across the cooling coil, combining sensible cooling and moisture removal within the same air-treatment process.

The system is designed to support stable humidity control in applications with significant moisture loads or humid outdoor conditions.

Multiple HVAC Functions

Different rooftop configurations can be selected according to project requirements.

Service-Friendly Design

The integrated refrigeration and ventilation structure simplifies the overall equipment arrangement.

Single-side service access on applicable configurations provides easier access to major components for inspection, troubleshooting and replacement.

This is particularly valuable for commercial rooftop equipment where minimizing service time can help reduce maintenance disruption.

Typical Applications

New Construction & RTU Replacement

Rooftop packaged units are suitable for both new buildings and selected replacement projects.

For replacement applications, matching the existing unit dimensions and duct connection arrangement can significantly reduce field modification.

Typical Rooftop HVAC Airflow

Certified Performance

Applicable product configurations are available with AHRI-certified performance and ETL listing according to the selected model and market requirement.

Certification status should be confirmed during product selection, especially for North American projects.
