■ Fans
Fans shall be vane-axial induced type of cast aluminum ally blades.
Low cost and high efficient running
■ Water distribution nozzile
The sater shall be distributed over the entire coil surface by precision molded ABS spray nozzle.
■ Pan & casing
Pan and casing shall be constructed of hot-dip galvanized steel gor long life and durability.
■ Recirculation pump
Pump shall be a close-coupled centrifugal type.IP54 motor for dirp-proof.
■ Louver
Air entrainment efficient is a good and the spray branches is minimum like as honeycomb.
■ Eliminators
Highly Efficient Removal of Arsenic Acid
Our drift eliminator efficiently removes up to 0.002% arsenic acid contamination of the circulating water flow by rapidly transforming the direction of air flow three times using air pressure.
The user can extend the space of the drift eliminator supporter, making air flow resistance low.
Notice: Saturated air meeting cold air produce the moisture you may see on the drift eliminator. Such moisture is normal and does not affect the device’s performance.
■ Strainer
Strainer shall be constructed of stainless steel NO304 for prevent the erodion and be apt to checking,dismantle,assembling and cleaning.
