HDB

Range: 10÷330kW

INDIRECT AIR/AIR FREE-COOLING

The indirect Free-Cooling is different from the direct one since:

• it does not create contamination of the air inside the server room with the outside air
• dust and pollutants don’t enter into the server room and no additional filtration is required
• there is no increase of latent load.

Consequently, there is a clear reduction of energy consumption.

EC PLUG FANS

The EC type ventilation on both air flows allows:

• high efficiencies at partial loads
• reduction of noise emissions
• to follow even little variations of the thermal load

The fans are “hot-swappable” and their consumption is displayed real-time on the on-board display.

CHILLED WATER OR DIRECT EXPANSION INTEGRATION

Whenever the external climatic conditions do not allow to cover the internal heat load only with the indirect Free-Cooling + Evaporative Cooling mode, an integration with mechanical cooling is needed.

The option of a refrigerating circuit with modulating BLDC compressors for R410A, expansion valve with electronic control and finned evaporator with hydrophilic treatment. Alternatively, an additional chilled water coil can be connected to an external chiller.

The indirect Free-Cooling of DataBatic units can be extended to a greater number of hours per year and to more climatic zones thanks to the combination of the Evaporative Cooling system and of the air-to-air cross-flow heat exchanger.

The decrease (and in some cases the cancellation) of the mechanical operation thus leads to a twofold benefit: the reduction of running costs (lower PUE levels) and the reduction of implementation costs thanks to lower installed electrical powers.

The HDB units can be equipped with the “refrigerating circuit option” and are fully factory assembled in a one-piece solution to facilitate the installation.
