ISO 9001 Certified

Data Aire® ... the pioneer and builder of the most complete line of precision cooling equipment Data Aire's first precision cooling system was developed by data processing engineers who sought optimum environmental conditions for early computers. It was clear that "people comfort" air conditioning system were unable to meet the environmental requirements of computers and data processing equipment. Precision environmental control equipment with high sensible cooling ratios was a necessity. Problems with paper sticking , head crash, and static electricity were eliminated. Humidity fluctuation were controlled saving possible electrical and mechanical failures and more importantly ­ Downtime. Data Aire's innovative response to the challenge of eliminating problems within the computer room environment was the start of wide use precision cooling. As in the past, Data Aire is meeting today's challenge of not only the computer room but also the ever expanding telecommunications industry where precision cooling is vital to our everyday communications. Telecommunication equipment requires a controlled environment with clean and properly distributed air. As in the computer room, the environment must be precisely controlled ­ 24 hour a day, 365 days a year. Data Aire produces solutions.

Data Aire systems are designed for data centers, telecommunication sites, or anywhere process cooling is required. Chilled water units are available in 7 through 50 nominal tons with upflow or downflow air distribution. Each unit is factory run tested and put through a comprehensive quality control procedure.

HIGH PERFORMANCE/LOW COST

Engineered for performance and reliability, each Data Aire Series unit comes with Data Aire's commitment to excellence. This commitment began with Data Aire's first process cooling unit and has continued for more than 30 years of building the industry's finest control equipment.

DATA AIRE DELIVERS

Standard ship cycle is 30 days from date of order. With an optional premium "quick ship", units can be expedited to ship in little as one week. All units are built to your specific order and specification. Call your nearest Data Aire representative for more information.

COMFORT

Computer rooms and other environmentally controlled spaces require air which is clean and properly distributed, with precisely controlled temperature and humidity. Building or "people comfort" cooling systems are not designed to meet these demands. Data Aire Series chilled water units are designed to maintain temperature and humidity and properly distribute the required clean air in environmentally controlled areas.

DESIGN

Data Aire Series units feature a specially designed compact tubular steel frame which allows for minimum space requirement of air conditioning equipment in the controlled area. Although compact, all parts are easily accessible providing excellent serviceability. Units are finished with a furniture-grade insulated steel cabinet painted in your choice of color. The heart of the system is the Date Alarm Processor-II TM, a microprocessor based controller designed for precision environmental control. The DAP-IITM not only controls and monitors temperature, humidity, airflow, and cleanliness, it provides component runtimes, alarm history, and automatic self-test. All information is provided on a 2 row, 80 character, backlit liquid crystal display (LCD).

DESIGN FEATURES

CABINET and FRAME

Data Aire chilled water series units are constructed with heliarc welded tubular steel frame providing for maximum strength and ease of access. Side and front panels can be easily removed with quarter-turn fasteners allowing full access to all unit components. All panels include 1 inch thick, 11/ 2 pound density insulation for protection and sound attenuation.

REHEAT

Three stage electric reheat is standard. Low-watt density finned tubular sheathed coils provide ample capacity to maintain room conditions during dehumidification. Low-watt density coils eliminate ionization associated with open air electric resistance heating.

HUMIDIFICATION COIL SECTION

Designed for draw through application, the computer selected A-frame coil provides greater efficiency in the cooling and dehumidification process. Air is drawn through both slabs at velocities that provide effective surface exposure with minimum turbulence. The chilled water flow is controlled by a 3-way modulating mixing valve for accurate and economical temperature and dehumidification control. Bypass air is provided to prevent saturated air from being introduced into the controlled space. The coil sits in a stainless steel drain pan. Steam Generator Humidifier Units are furnished with an electric steam generator humidifier with "quick change" disposable cylinders and auto-flush cycle. The steam generator humidifier with its patented control system optimizes cylinder life by concentrating incoming water to a predetermined conductivity much higher than that of any entering water. The control system continuously monitors the conductivity in the cylinder through its electronics which allows water to be flushed as often as is necessary to maintain the level at this design conductivity. The high design conductivity results in a minimum flushing of heated water which saves energy. The humidifier is designed to allow all units at any voltage to produce full rated steam output at an optimum low water level.

FAN SECTION

The centrifugal, forward curved, double width, double inlet blower configuration is engineered for quiet reliable operation. The dual belt driven variable pitch drive section provides adjustable air flow capability to match the load requirements of the controlled space. The draw through design insures even air distribution across the coil and bypass, low internal cabinet pressure losses and static sealing of the filter section. Motors are mounted on an adjustable slide base and have internal overload protection.

FILTER SECTION

Units are provided with 4 inch deep, 30% efficient (based on ASHRAE Std. 52-76), pleated filters. The filter section is accessible from the top or side on downflow units and both sides on upflow units.

CONTROL SYSTEM

The microprocessor based Data Alarm Processor-II TM offers the definitive answer for precision environmental control. The DAP-IITM control system not only controls and monitors temperature, humidity, airflow, and cleanliness, it provides component runtimes, alarm history, and an automatic self-test of the microprocessor on system start-up. All messages are presented in a clear vernacular format and sequentially displayed on a 2 row, 80 character, backlit liquid crystal display (LCD). OPERATION - Highly reliable, flat, sealed switches with tactile feedback allow unit on/off operation, menu selection for programming, operational information, diagnostics, and historical data. Multilevel password prevents unauthorized access. Alarm conditions are enunciated by an audible alarm. The alarm silence switch will quiet the audible alarm but the display will continue to indicate the alarm condition until the problem is corrected.
