Air-cooled air conditioners use chilled water from an external chiller. Chiller can be air-cooled or water-cooled as well as free-cooling.
Water flow through the heat exchanger is regulated by the built-in three-way valve.
Closed control systems ROVER are considered as the best solution for air conditioning in areas such as server rooms, telecommunication rooms, data centers, laboratories. Closed control systemsare needed to cool computer racks and power equipment with critically high thermal loads.
ROVER conditioners use ozone-saving freon R410A.
