Chilled Water Units, Downflow with Backward Curved Fans
Perimeter cooling for medium and large data center environments
Uniflair LE Features & Benefits
Single points of failure in the system have redundant components to maintain availability and reliability.
Electronic expansion valve
Refrigerant flow optimization at any load and temperature conditions. Continuous indirect refrigerant charge monitoring
Direct drive motors
Stress on bearings is nearly eliminated, increasing useful life. Allows integral fan/motor assembly to be factory balanced, which lowers vibration and expedites startup.
Multi-functional Microprocessor Controller
Allows the units to restart after a power failure without intervention; Allows for room level redundancy with up to ten units operating in a group; User friendly navigation with icon based displays to indicate mode of operation as well as room conditions; Allows for communication with multiple Building Management System protocols.
Active response control
Monitors and actively adjusts cooling capacity to ensure proper server inlet temperatures. Through the microprocessor controller, visibility into the operation and status of the unit is provided.
Provides management by connecting the device directly to the network with a dedicated IP address, avoiding the need for a proxy such as a server. Management is available via Web browser, Telnet or SSH. Notification features inform you of problems as they occur.
Local area network
Creates a shared control between all the available resources for maximum energy efficiency and controlled management of the group during emergency situations
Building Management Systems
Units are designed to work with the most common BMS systems including BACnet and Modbus.
Automatic Floor Pressurization System
Ensures stable airflow pressurization under floor regardless of changes made above the floor
All the monitoring devices on board the unit allow for preventive maintenance and a check of the working condition of the system while its in operation.
Allows critical components to be maintained/replaced while the system is in operation.
Easy service access
Allows for all serviceable components to be replaced/maintained by easily accessible panels/doors.
Total Cost of Ownership
Modular design of the mechanical and control systems allow for gradual build-up of the cooling infrastructure to match the cooling demand of the facility. This greatly reduces CAPEX expediture and provides deferred investment throughout the life of the facility.
Achieved by utilizing cool ambient air during winter months to take advantage of economizer hours and eliminating compressor operation.
Connection between the Computer Room Air Conditioners and the chillers guarantees energy efficiency, based on real instantaneous load conditions (optional)
Quiet and efficient operation of compressors, connected on a common refrigerant circuit for staged capacity control (not available for some models/configuration)
Electronically Commutated Fans
Provide the highest efficiency and reduce total power consumption by matching the airflow requirements to the heat load of the data center.
