Description

LBC series is a circular counter flow cooling tower which adopts a highly efficient rotating sprinkler head system to induce self rotation in distributing hot water across the fillings. The Fiberglass-Reinforced Polyester (F.R.P.) casing is circular shaped thus eliminating special positioning requirements and is not affected by prevailing wind directions. It further allows quick and easy installation due to light-weight and compactness. LBC is the most conventional, economical, and practical cooling towers with sizes ranging from 5 tons to 1500 tons. The LBC standard series is suitable for general HVAC applications and various manufacturing process cooling. LBC-LN (Low Noise) type features an upper fan stack and splash mat for running at lower fan speed based on the feature of fan blade. LBC-LN series has lower noise level than the standard LBC model by 7~10 dB.

Product Features
Casing, Water Basin, Water Sump
The Fiberglass Reinforced Polyester (F.R.P.) cooling tower casing, water basin, and water sump have been designed for durability. F.R.P. features good structure stress, non-chap, non-crack, non-aging, firmness and long service life.

Fan Drive
LBC models below 200RT have direct driven fans by a low-noise motor. Model LBC-225~1500 are driven by general V-type belt that features wide contacting area, light vibration and stable transmission. Belts have FRP protection cover that leads to moist-resistance, smooth running, wear-resistance, firmness, low refueling and easy maintenance.

Fan Blade
Aero-dynamically designed propeller fans operated at low speed are used to save on power consumption and to ensure quiet operation. Models below 30RT are made of special reinforced plastic fans. Model LBC-40 upwards are made of aluminium alloy.

Water Distribution
A highly efficient self-rotating sprinkler head system made of reinforced plastic is used for the smaller range of towers. From LBC-70 models upwards the sprinkler head is made of aluminum alloy. Spinkler pipes and stand pipes are of PVC plastic tubes featuring low water pressure, even water distribution, lower water consumption and maximum heat exchange efficiency.

Filling
The embossed filling is made of PVC sheet that is processed by surface treatment of wrinkled and corrugated pattern. The filling is glued together to extend the retention time of flowing water and enable adequate surface in contact with the ambient air to increase heat exchange efficiency. PVC filling is suitable for operation with inlet water temperature up to 47°C. Additional filling options offered include CPVC and PP material for inlet water temperatures above 47°C.
Liang Chi offers Model LBC-W which is specially designed with Preventive treated wood filling, suited for industrial cooling of high temperature and poor water quality.
Inlet Louver
P.V.C. plastic mesh to prevent objects entering the water basin.
