Energy-Efficient Cubic Air Cooler For High Temperature Cold Room

Overview

The Energy-Efficient Cubic Air Cooler (Model: LA/LF/LC) is a modular cooling solution designed by STELX for high-temperature cold rooms (-15°C to 0°C) in food processing, pharmaceutical logistics, and distribution centers. Built with German-engineered aerodynamics and EC fan technology, this cubic air cooler delivers exceptional energy efficiency, precise temperature uniformity (±0.3°C), and zero-drip performance—all while adhering to strict hygiene standards. With a cooling capacity of 5 ~ 130 kW and compatibility with multiple refrigerants, it balances compact design with industrial-strength reliability, making it a trusted choice for multinational cold storage operators.

EC Fan Technology for Maximum Energy Savings

At the heart of this cooler is the EC (Electronically Commutated) fan motor, which intelligently adjusts airflow parameters in real-time based on thermal load variations. Unlike traditional AC motors, EC motors slash power consumption by up to 40% during partial loads, delivering significant energy savings without compromising performance. The dynamic speed-pressure modulation ensures consistent cooling even during door openings or product rotation, maintaining temperature uniformity critical for perishable goods.

Durable & Hygienic Construction

Constructed with 304/316 stainless steel or triple-layer powder-coated galvanized steel, the cubic housing resists corrosion and withstands frequent sanitation protocols—ideal for hygiene-sensitive environments like food and pharmaceutical facilities. The revolutionary 45° angled double-insulated water tray ensures rapid condensate evacuation, eliminating external surface sweating and dripping contamination. All materials (including titanium, aluminum, and copper) meet industry standards for durability and safety, supporting long-term 24/7 operation.

Modular Design for Easy Installation & Maintenance

The lightweight modular framework reduces installation time by 30% compared to traditional coolers, with integrated structural brackets enabling both ceiling-suspended and floor-mounted installations. Maintenance is simplified with slide-out coil trays and front-service components, allowing tool-free access to coils and fan arrays for effortless cleaning. Optional accessories like electrically heated baffle kits and fan anti-condensation heaters enhance operational resilience in high-moisture or low-humidity environments.
