Direct Expansion air cooled precision air conditioners, Underfloor EC fans and VSD compressors

Product Description

AVAILABILITY

Redundant Components: 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
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.
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.

ENERGY MANAGEMENT

Building Management Systems: Units are designed to work with the most common BMS systems including BACnet and Modbus.
Network interface: 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.
Automatic Floor Pressurization System: Ensures stable airflow pressurization under floor regardless of changes made above the floor
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

SERVICEABILTY

Operational Service

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.
Service monitoring

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.

TOTAL COST OF OWNERSHIP

Optimized management: Connection between the Computer Room Air Conditioners and the chillers guarantees energy efficiency, based on real instantaneous load conditions (optional)
Modular strategy: 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.
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.
