INTRODUCTION

Product Information

The Data Aire Mini-Plus (DAP) environmental control, direct expansion, single circuit or chilled water-
cooled Computer Room Air Conditioner (CRAC) equipment provides a high sensible cooling, is self-
contained, factory assembled, piped, wired, and factory tested prior to shipment. These units include
an enclosure/cabinet assembly, fan section, filter section, cooling coils, controls, and interconnecting
piping internal to unit. This unit is normally mounted above the ceiling tiles.
The Data Aire CRAC unit provides cooling, reheat, humidification, dehumidification and air filtration.
The unit is provided with a Data Aire Mini-dap4 microprocessor controller for precision control. The unit
must be operated in a conditioned space within the operating envelope ASHRAE recommends for data
centers. Operating outside this envelope can alter the operating performance and decrease equipment
reliability. Return air to the unit must be no cooler than the ASHRAE recommendation for proper unit
operation. Operating below this can alter the operating performance and decrease equipment reliability.
Refer to ASHRAE's publication, "Thermal Guidelines for Data Processing Environments."
