Yuju EnvironTech is a professional HVAC manufacturer 

Rooftop Package Unit 15 SEER2 & 18 SEER2
Rooftop air-conditioning units combine cooling, heating, ventilation, and air purification in one system, offering high efficiency, energy savings, and easy installation with low maintenance. Suitable for both new and renovated buildings, they are widely used in shopping malls, hotels, offices, cinemas, gyms, factories, and industrial facilities such as machinery, chemical, and electronics plants.

Key Feature
High Energy Efficiency
Energy ratings up to 19 SEER help reduce utility bills. Direct evaporative refrigeration ensures high system efficiency without secondary heat exchange. DC inverter technology allows precise control of unit performance to match room load, maximizing energy savings.

Quiet Operation
ECM outdoor and blower motors reduce noise levels. Outdoor placement with only air duct indoors minimizes indoor noise and saves space.

Flexible Installation
Supports horizontal or downflow applications. Universal curb design allows convenient installation and replacement. Single-side service panels provide easy access for maintenance.

Reliable & Safe
Rainproof, heat-insulated, and well-sealed to protect electrical components. Electrical control box keeps wiring safe from roof leaks. Multiple protection features including high/low pressure, overload, phase failure, and overheating ensure safe operation.

Superior Dehumidification
Direct evaporative refrigeration with low dew point dehumidification maintains stable indoor humidity in low temperature or high humidity environments.

Wide Range of Adaptation
Available in single cooling and heat pump types, as well as return air or fresh air configurations. Supports cooling, heating, dehumidification, filtration, and other air treatment functions.

High-Quality Components
High-efficiency heat exchanger ensures effective thermal transfer. Refrigerant cooling system protects the control board for reliable electrical performance.

Compact & User-Friendly Design
Integrated layout combines refrigeration and ventilation systems efficiently. Easy troubleshooting and part replacement thanks to highly accessible internal design.

Certifications
AHRI certified, ETL listed for quality assurance and compliance.
