Understanding the Backbone of Commercial Air Conditioning

In commercial and industrial environments, the selected HVAC equipment directly determines the energy efficiency, air distribution quality, and long-term operational stability. Among the most widely used systems, rooftop packaged units, water-cooled packaged units and split ducted systems are included. Each one is designed for different building conditions, installation layouts and performance requirements.

ZERO Technologies, featured in ACR LATINOAMERICA, incorporates these three systems into its comprehensive array of commercial products, providing end users and project developers with flexible and efficient solutions built on modern engineering standards.

Rooftop Package Unit

The Rooftop package unit integrates all the key components of air conditioning - the compressor, evaporator, condenser, and fan-into an outdoor cabinet usually mounted on building rooftops, maximize indoor leasable space and allow centralized maintenance, reducing disruption to operations.

The Rooftop package unit is especially valuable in retail complexes, exhibition halls, theaters, and factory workshops that demand efficiency and reliability.

ZERO's rooftop package unit is equipped with a DC inverter compressor with a permanent magnet motor, enabling smooth capacity regulation and significant energy savings. AMCA-certified belt-driven fan provides steady airflow and external static pressure of up to 430 Pa, ensuring reliable air distribution even in complex duct systems. The unit adopts galvanized steel plate structure, which has structural durability and wind and rain resistance, and is suitable for year-round operation in roof environment.

Key advantages:

Wide capacity range: 3-130 TR

DC inverter Compressor with PM Motor

AMAC-Certified Belt-Driven Fan

High ESP(80-430Pa)

Water Cooled Package Unit

The water cooled package unit uses water as the heat transfer medium instead of the traditional outdoor air. It is usually installed in an indoor machine room and connected to a cooling tower or other water circulation system.

Water cooled package unit delivers stable, efficient performance with minimal impact from outdoor temperatures. Their flexible installation and reduced lifecycle costs make them ideal for high-consumption facilities such as malls, theaters, and industrial workshops.

ZERO's water cooled package unit uses high-efficiency scroll compressors and have high static pressure capacities of 100 to 450 Pa to ensure reliable airflow in long duct systems. Its built-in control system simplifies user operation and supports fault diagnosis, maintenance scheduling and energy consumption monitoring. The design emphasizes space efficiency and quiet performance, reducing mechanical vibration and noise, especially suitable for dense urban built environments.

Key advantages:

Capacity range: 4-120 TR

High-Efficiency Scroll Compressor

High ESP (100-450Pa)

User-Friendly Built-In Controller

Split Duct Unit

The split duct unit separates the indoor and outdoor units, which is suitable for installation scenarios with limited space on the roof or in the computer room. The indoor machine is usually hidden in the ceiling or the machine room, and the treated air is transported through the air duct to keep the system low-key without affecting the indoor appearance.

Split duct unit enhances indoor comfort with a concealed design that maintains aesthetics and delivers uniform long-distance airflow. In hotels and office buildings, zoning flexibility and quiet performance enable tailored comfort across different spaces.

At ZERO, split duct unit is designed to support horizontal or vertical installation to accommodate a variety of ceiling structures. The system is compatible with all 24 V thermostats and includes a washable aluminum filter to extend service intervals and reduce maintenance costs.

Key advantages:

Capacity range: 7.5-40 TR

Flexible installation direction (horizontal/vertical)

Compatible with All 24VThermostats

Durable, Washable Aluminum Filter

Multiple voltage configurations (208~230V-1PH 50/ 60Hz, 208~230V-3PH 60Hz, 380~415V-3PH 50/60Hz, 460V-3PH 60Hz) are available to ensure that each device meets regional standards and project requirements.
