Round Modular Dry Cooler
DMR is a revolutionary modular dry cooler that ensures ultra-high specific power, thanks to the combination of technological solutions designed and tested by Althermo.
The exchange surface of the microchannel heat exchanger, thanks to the special cylindrical shape, is 50% higher compared to a traditional configuration with the same footprint. This characteristic, in addition to the possibility for the heat exchanger to be installed very close to walls, ensures a remarkable reduction of the entire installation surface up to 75%.
The DMR module is the highest expression of energy efficiency on the market of dry coolers and it can be provided individually as a single module (to be mounted on the installation site) or in combination as a multiple modules configuration. The standard version is provided with EC fans but AC fans can be mounted as well.
In addition to this, other options for DMR are available: protective coating in case of heavy duty sites of installation (inox frame and ElectroFin treatment on the heat exchanger) and closed-circuit operation through the installation of another plate heat exchanger with recirculating pump.
Cooling capacity: from 30 to 2300 kW
Fan diameter: 800 and 910 mm
Number of fans: from 1 to 20
-75% of footprint
A single module can dissipate up to 56 kW (Δt 5 °C air in – water out, EG 25 °C) with a total footprint of only 1.21 square meter. Thanks to its distinctive shape, it can draw air in from all around (360°) and can be installed very close to walls. The combination of these elements allows to reduce by 75% the installation area of the dry cooler.
