1. Client Background
Our client is a well-established distributor in South Korea specializing in industrial thermal solutions. Their end customer, one of Korea’s leading consumer electronics brands, required a batch of UL-certified outdoor air conditioners for multiple equipment cabinet installations across their operational sites.
Given the company’s globally recognized standards, UL (Underwriters Laboratories) certification was a strict prerequisite, representing a commitment to both safety and quality.
2. Project Requirements & Challenges
🛡 Strict UL Certification Compliance
UL certification was non-negotiable. It served as a critical benchmark for safety, compliance, and global approval within the client’s internal standards.
High Cooling Demand
Due to continuous operation and dense electronic components, the cabinets generated significant heat, requiring high-performance cooling systems rated at 1000W and 3000W.
🌧 Tough Outdoor Conditions
Cabinets were installed outdoors, exposed to rain, dust, sun, and temperature fluctuations. The air conditioning units needed to be rugged, weather-resistant, and corrosion-proof.
Large Quantity, Short Lead Time
The project required 64 UL-certified units delivered within a tight schedule, aligning with the customer’s rapid rollout timeline.
3. Cooltechx’s UL-Certified Solution
Cooltechx proposed two outdoor models tailored to meet both compliance and performance needs:
Model HDC010AD – 1000W Cooling Capacity
Model HDC030AD – 3000W Cooling Capacity
Key Solution Highlights:
Official UL Certification
Both models are fully UL certified, giving the client confidence in installation safety, regulatory compliance, and smoother internal approval processes.
Reliable Cooling Performance
Engineered for industrial-grade heat loads, the units provided stable and efficient cooling, preventing overheating and system failures.
🌦 IP55-Rated Weather Protection
Built for outdoor durability with a sealed, anti-corrosion design, the units withstand harsh environments including coastal, industrial, and high-dust settings.
Easy Integration & Installation
Side-mount and top-mount options with pre-configured mounting holes simplified field installation and integration into different cabinet designs.
4. Delivery & Support
Cooltechx completed production, UL testing, and final inspection for all 64 units within 3 weeks.
Each unit was securely packed in reinforced wooden crates for sea freight, ensuring safe international delivery.
The client also received technical consultation, installation guides, and ongoing after-sales support from Cooltechx’s team.
5. Customer Feedback & Results
After deployment, the customer reported:
Stable internal temperatures across all cabinet sites
Zero overheating or alarm events
Hassle-free project approval thanks to the UL documentation
Positive feedback from the installation team and project managers
The Korean distributor expressed strong satisfaction with Cooltechx’s responsiveness, product quality, and technical support, and confirmed plans for future collaboration.
6. Strategic Impact
