YTA Adiabatic Air Handling Unit AHU Industrial HVAC System Dehumidifier Chilled Water Factory Prices Low Cost 4000 Cfm

Features

The YTA series units are the ideal solution to cool air in systems where environmental sustainability and energy savings are priorities, such as large, best-of-breed data centers, ensuring a performance similar to direct FREE COOLING with-

out however contaminating air-conditioned premises, with air contains pollutants, dust, and humidity. The units are de-

signed to be installed outdoors, typically on the roof,and consist of two treatment sections, one for inside air and

another for outside air, physically separated and with two filtering, ventilating and completely independent sections.

Indirect free cooling with adiabatic cooling

The indirect FREE COOLING system with adiabatic

cooling includes both the technology of air-to-air heat

recovery and that of adiabatic cooling, in which some

water is evaporated to cool down outside air.
Being able to exploit the FREE COOLING system even at
temperatures of 30°C/35%Rh, these units achieve very

high energy efficiency, offering energy savings of up to

80% compared to a comparative to a mechanical cooling system.

An innovative evaporative panel

In order to maximise the system efficiency, an innovative evaporative panel is used that allows saturation efficien-

cy greater than 90% using more than 60% less water.

Thanks to the OXYVAP® system, formed by special

formed and treated aluminium fins, it is possible to:

• Use drinkable water. No expensive water demineralisa-

tion systems are required.
• Cut down on water consumption. Over 60% water

reduction with respect to conventional evaporative panels and spraying systems.
