40-Ton Commercial Rooftop HVAC Project for Florida

Project Overview

Yuju EnvironTech is currently manufacturing a customized 40-ton packaged rooftop air conditioning unit (RTU) for a commercial building project in Miami, Florida, USA.

The customer required a complete commercial HVAC solution designed specifically for the U.S. market, including R-454B refrigerant, 240V / 3-phase / 60Hz electrical configuration, fresh air ventilation capability and corrosion-resistant construction suitable for long-term operation in a coastal environment.

Beyond supplying equipment, our engineering team participated in the project from technical evaluation through production planning, helping ensure the rooftop unit meets the customer's installation requirements, transportation constraints and applicable U.S. standards.

Customer Requirements

The project was developed according to the customer's engineering specification and installation requirements.

Item	Project Requirement
Equipment	Packaged Rooftop Air Conditioner
Cooling Capacity	40 Tons
Airflow	Downflow
Fresh Air	Outdoor Air Intake Hood
Refrigerant	R-454B/R32
Electrical Supply	460V / 3 Phase / 60Hz
Installation	Permanent Commercial Building
Destination	Florida, USA

The customer also requested a corrosion-resistant design suitable for coastal environments together with complete engineering documentation and international shipping support.

Engineering Challenges
Large commercial rooftop HVAC projects involve much more than selecting cooling capacity. Before production, our engineering team evaluated several key technical factors to ensure long-term performance and smooth international delivery.

U.S. Refrigerant Compliance
The system was designed using R-454B refrigerant, supporting current U.S. environmental regulations while maintaining high cooling efficiency.

60Hz Electrical Compatibility

All major electrical components were selected for reliable 60Hz commercial operation, ensuring compatibility with North American power systems.

Coastal Corrosion Protection
Because the equipment will operate in Miami's coastal climate, corrosion resistance became a major engineering consideration during material selection.

Oversized Equipment Transportation

The overall dimensions required careful logistics planning to optimize container loading and reduce transportation risk.

Quality Verification
Every major production stage includes inspection and testing before final assembly.

Long-Term Reliability
Component selection focused on stable commercial operation, simplified maintenance and extended equipment service life.

Customized Engineering Solution

To match different operating environments and project budgets, two engineering configurations were prepared for evaluation.

Premium Coastal Configuration

Designed specifically for high-humidity and coastal installations.

Aluminum cabinet construction
316 marine-grade stainless steel fasteners
Factory epoxy-coated condenser coils
Maximum corrosion protection
Standard Commercial Configuration

Designed for general commercial applications.
Galvanized steel cabinet
Standard factory hardware
Aluminum-copper heat exchanger
Cost-effective commercial solution
Both configurations maintain the same cooling performance while providing different levels of environmental protection.

Manufacturing Process

Following engineering approval, the project entered the manufacturing phase.
The production process includes:
Precision sheet metal fabrication
Heat exchanger assembly
Refrigeration system installation
Electrical wiring
Controller integration
Factory performance testing
Final quality inspection
Every manufacturing step follows standardized quality procedures to ensure consistent product performance before shipment.

Export Packaging & Ocean Freight

Because of the equipment dimensions, transportation planning was considered during the engineering stage.
The rooftop unit will be professionally packaged using export-grade materials with reinforced protection for international ocean transportation.
Our logistics team also evaluates container loading methods, lifting points and shipping documentation to reduce transportation risks during overseas delivery.
