MONTAIR WOPR series is a range of high performing chilled water air conditioning units specifically designed to be closely coupled with the apparatus which generate the thermal load within a data center.
These units are equipped with EC Plug-Fans with backward curved blades, a large cooling coil optimized to operate with high inlet water temperature and wide deltaT. Thermal load variations are covered by the simultaneous action of 2 or 3-way modulating valve and the automatic fans speed control by means of regulation logics managed by a microprocessor and an advanced user interface.
Excellent performances are achieved when combined with Montair high efficiency Free-Cooling chillers and with the new available liquid Chillers with low GWP refrigerants.
