MARK


MARK is a packaged cooling system specifically designed for the telicommunications industry. It offers the flexibility of both indoor and outdoor installation, and offers duel power supply for both mains and UPS to ensure minimised downtime. All units include free- cooling with +45% of airflow compared to the mechanical cooling operation. This allows more cooling power to the air- conditioned room, and maximised energy saving.

The control system features an 8 line digital display, full password protected menu system, and comes included with integrated RS485, ethernet, and LAN connection for full connectivity. Optional accessories include electric heaters, clogged fliter alarm, and water pressure alarm for maximum peace of mind.

All three models come in the same footprint and range from 5.8 to 9.1 KW total capacity

MARK 06 Cooling capacity 5.8KW

MARK 09 Cooling capacity 9.0KW

MARK 10 INV Cooling capacity 9.1KW
