Cooling capacity
90/1300 kW
Our range of coolers includes both dry (DC-D series) and adiabatic models (DC-W series), available in single- or double-row configurations, offering maximum installation flexibility according to available space. Designed for outdoor applications, these units combine robust construction with weather resistant materials, ensuring consistent performance and long operational life even under demanding conditions.
Adiabatic technology is based on a natural thermodynamic principle: the evaporation of water to remove heat from the air. In adiabatic coolers, appropriately wetted cardboard honeycomb panels saturate the air passing through, reducing its temperature before it reaches the heat exchange coils. The water flow is managed by an HT-Cooling proprietary microprocessor control, developed to optimize unit operation and minimize water consumption. This process ensures significantly higher efficiency compared to dry solutions, maintaining high performance even under critical climatic conditions.
DC series units are constructed from 20/10 pre-painted sheet metal, providing high structural robustness. Connections are protected by dedicated covers safeguarding the collectors, and, upon request, various surface treatments are available depending on the installation site to preserve the cooler’s long-term performance.
State-of-the-art heat exchange coils feature optimized tube and row geometry to maximize heat exchange capacity. Installed in a V-configuration within the frame, they are separated by a partition allowing independent operation of the two fan rows (V2 models). The coils are treated with an electrolytic coating to maintain corrosion resistance. Each unit is pressure-tested up to 18 bar to ensure tightness and long-term reliability.
All models are equipped with EC Brushless fans with variable speed, ensuring quiet operation, reduced electrical consumption, and precise airflow adjustment according to thermal load. EC technology guarantees high energy efficiency and reduced mechanical wear, extending operational life. In the V1 configuration, fans are set in a single row, while V2 models feature a double-row layout to increase airflow and heat transfer capacity.
The core of the range lies in the control system, designed, tested, and developed exclusively for HT-Cooling. The HT-Cooling platform provides complete management of both adiabatic and dry units, based on a fully programmed and parameterized system. The 7” touch operator panel (remote version also available as an option) allows monitoring of the cooler and adjustment of operational parameters according to line requirements, including:
• Delivery, return, wet bulb, ambient (temperature and humidity).
• Fan status.
• Installed pump status.
• Adiabatic system operation.
• Water level in the storage tank (if available as an option).
• Filling valve status (if available as an option).
The system integrates the EASY ACCESS 2.0 feature, simplifying monitoring and troubleshooting via HMI (Human-Machine Interface) and PLC, even from remote locations. EASY ACCESS 2.0 also supports remote assistance, enabling direct supervision of the unit status from any authorized location.
