Modulating Air-Cooled Water Chillers with Axial Fans and Free-Cooling System
Free cooling chillers with axial fans and integrated free-cooling system for continuous operation applications
Uniflair Free Cooling Chillers Features & Benefits
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.
Continuous current monitoring
Permits a continuous monitoring of the compressor’s absorbed current to signal possible discrepancies with the default values (Optional).
Single points of failure in the system have redundant components to maintain availability and reliability.
Separate power input
Draws power from the external UPS for mainboards and heaters to monitor and protect the unit even in complete power failure mode (optional)
Electronic expansion valve
Refrigerant flow optimization at any load and temperature conditions. Continuous indirect refrigerant charge monitoring
Allows continuous operation in winter mode even with compressor failure
Full load operation in less than 3 minutes with specific arrangements permits undersizing of the storage tanks
Building management system integration
Send alarms and data points allowing you to manage critical building infrastructure from a single system.
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
Provides proactive control and real-time monitoring via a four line, eighty character, alphanumeric display.
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.
Allows critical components to be maintained/replaced while the system is in operation.
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.
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.
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)
Variable speed fans
Variable speed fans reduce energy consumption during off-peak cooling periods.
Integrated Hydronics Package
Includes all the necessary components to make one connection to the chilller without the need of external connections to auxiliary equipment such as pumps, increasing the speed of deployment.
Integrated pumps adjustment system
(Optional) VSD onboard pumps are available for continuous adjustment of the chilled water loop available pressure. This provides automatic adjustments in Chilled water flow due to changes in cooling demand which ensures efficiency of the chilled water system.
