This unit is able to fulfil the highest requirements for a wide range of applications. By entering the load and output into your customer system, the air supply system automatically and directly adapts to the given requirements. The frequency-controlled drive unit offers a wide control range with optimised demand matching. In addition to energy savings and higher efficiency, this also results in lower maintenance requirements. The non-contact, oil-free screw unit ensures high air flows with low pulsation and lends itself to "master/slave" operation. Integrated accessories include a non-return valve, intake filter, sound absorbers and ventilation/bleed system. An air blast cooler is also available.

Complete of free-cooling ECF and ECFS series
Offering exceptional performance levels in terms of efficiency, the units in the new series are able to exploit low ambient air temperature conditions whenever available - all year round. The new range, which extends the existing line of air conditioning units, has been specifically engineered to provide the exceptional reliability demanded in industrial application. Although the maximum saving in energy is obtained during continuous operation of the systems for 24 hours/day, chillers equipped with free-cooling allow very substantial power consumption savings even with short periods of operation, while also guaranteeing longer life expectancy and reduced maintenance requirements when compared to conventional chillers. The operating methods utilized guarantee energy savings typically in excess of 40% with respect to conventional units.
