CASEN Efficient-Elliptic® HEAT TRANSFER TUBE
The oval coil used in CASEN's latest evaporative condenser. The elliptical tube design maximized the effective tube surface area while lowering airside pressure drop and allowing for higher water loading. The combination of the elliptical shape tube in the Efficient-Elliptic® orientation increased heat transfer efficiency and resulted in the most capacity per plan area of any evaporative condenser on the market.
Oval tube coil utilized the same material tube introduced in the original coil, but changed the orientation of the tubes to improve the tubes air to water interface for increased heat transfer efficiency.
KEY BENEFITS
Effectively improve conversion efficiency
Low wind resistance
High wind speed
Low energy consumption
Increase water load
Use less refrigerant
Reduce weight
Reduce the cost
Tighter arrangement
K1: Low Wind Resistance
Under the same windward area, the net flow area of the elliptical tube heat exchanger is 17%~22% larger than that of the round tube heat exchanger.
K2: High Wind Speed (3.2m/s No air escape)
For heat exchangers with the same air volume and windward area, the actual net flow passage of the elliptical tube reduces the wind speed by 15-18%;
K3: High Performance
Efficient-Elliptic® heat transfer tubes have 40% more effective contact surface area than round tubes.
40% increase in effective contact surface area
