ThermoKey’s Modular Dry Cooler is designed for high efficiency and maximum flexibility. Each module includes 4 vertical microchannel heat exchanger (MCHX) cores and 2 top-mounted fans, ensuring optimal airflow and thermal performance.

To improve space management and increase heat transfer efficiency, the piping and manifold system is strategically positioned at the bottom of the unit. This smart configuration not only enhances performance but also simplifies integration into various system layouts.

The Modular Dry Cooler is highly customizable, with configurations ranging from 1 to 5 modules, and offers a wide range of accessories, electrical components, and anti-corrosion surface treatments. This adaptability makes it ideal for a variety of industrial cooling, HVAC, and data center applications.

Standard configurations:

• Container: 2,5 m height x 5 modules = 2600 kg
• Super Jumbo: 2,8 m height x 5 modules = 3050 kg

The Modular Dry Cooler is specifically engineered to meet the critical demands of data centers and IT cooling systems, where operational criteria are non-negotiable.

• High energy efficiency
• Operational continuity
• Long-term reliability performances
• High Redundancy

Thanks to the modular design, it’s possible to expand the capacity to meet growing demand, integrating modules in series or in parallel. The manual valve and flexible connectors, and the compact footprint with low weight, allow an easy power expansion, without service interruption and reduced installation costs.

The advanced microchannel heat exchangers ensure superior heat transfer efficiency with lower air pressure drops, directly contributing to reduced fan energy consumption up to -45%, improving the PUE (Power Usage Effectiveness) index.

Modular architecture enables scalable capacity expansion and N+1 or N+2 redundancy configurations, aligning with higher Tier data center requirements.

No specialized technical training is needed, making the process both simple and cost-effective. Additionally, each module includes a dedicated access window for internal cleaning, eliminating the need to disassemble the fan section as required in traditional round tube coil systems.

Compared to traditional solutions with copper tubes and aluminum fins, microchannel heat exchangers built entirely in aluminum alloys significantly reduce galvanic corrosion. This key advantage not only ensures a longer lifespan but also delivers superior performance throughout the heat exchangers’ operational life, thanks to the optimized contact between fins and tubes.

The use of MCHXs in an optimized configuration ensures very low air pressure drops and high airflow uniformity, which significantly improve aerodynamic efficiency. This setup reduces fan power consumption up to -30%, leading to a noise reduction of up to -4 dB(A).

Compared to traditional round tube technology, the Modular Dry Cooler offers up to:

• -33% footprint
• -20% weight on the roof
• -40% installation costs
• -15% transportation cost
