EX Series - Low Noise Fan

EX Klsb, MEX Kls is the upgraded version of EX-KL Type which obtained CTI Certification. It is suitable for resident ial area for abating noise and drift loss of cooling towers.

*KT mark of Korean new technology.
*CTI(Cooling Technology Institute) certification for thermal performance.

Compact and Light Weight			High-efficiency fan and fill enable to save the installation space, time, and operation weight.

Energy Saving			High- efficiency integral fill and minimal mechanical power fans help reduce operation & maintenance costs with their simple structure.

Quiet Operation Sound			Unique design of Cross Flow Type has little water-dropping-sound. Newly developed low noise Axial fan guarantees quiet operation for adopting computer dynamic balancing.

Superior Corrosion Resistance			F.R.P. for basin and casing, hot dipped galvanizing for? structure

Drift Loss Abatement			Concentrated? drift loss can cause legionella's disease , but hardly does EX-Tower have drift loss.

Factory Assembled			As completely assembled at manufacturing plant, transportation and site installation are very convenient.

Outstanding Appearance			Good framed tower makes a superior looking skyline matched with building.
