TC Series - ES Class is an induced draft, counterflow, film filled, FRP square cooling tower designed for air conditioning and industrial process cooling applications. The ES Class is specifically designed to meet the 21st century challenges where the cost of energy, space and labour are ever increasing. It also incorporates a safety maintenance platform complete with safety railings for ease of maintenance. This highly efficient engineered design M class is a result of Truwater's commitment in the continuous R & D on cooling tower technology.

ES Class utilizes only components that are manufactured from the finest raw material and have been proven in the field. All components are designed to operate collectively to give the optimum overall cooling efficiency. This translates to lower operating cost and long term savings to the operator.

TC-ES Series Counterflow Tower Specification

1.0 General
The cooling tower shall be induced-draft, counterflow square, film filled, FRP Cooling Tower. For multiple cell units, watertight partition and balancing line shall be provided to create completely equal, separate cells. The cooling tower must be constructed with service and maintenance platform, safety handrail c/w caged ladder and vibration switch to meet DOSH (Department of Occupational Safety and Health) standards. Cooling Tower shall be Truwater TC Series ES Class or approved equivalent.

2.0 CAPACITY
Cooling Tower shall be capable of providing the thermal performance scheduled.

3.0 PERFORMANCE WARRANTY
The cooling tower manufacturer shall guarantee that the tower supplied will meet the specified performance conditions when the tower is installed according to plans. If, because of a suspected thermal performance deficiency, the Owner chooses to conduct an on-site thermal performance test under the supervision of a qualified, disinterested third party in accordance with CTI standards during the first year of operation; and if the tower fails to perform within the limits of test tolerance; then the cooling tower manufacturer will pay for the cost of the test and will make such corrections as are appropriate and agreeable to the Owner to compensate for the performance deficiency.

4.0 CONSTRUCTION
The cooling tower main frame structure shall be hot dipped galvanized steel (HDGS). The casing, louver and fan cylinder shall be made of Fiberglass Reinforced Polyester (FRP).

5.0 MECHANICAL EQUIPMENT
5.1 Fan(s) shall be propeller type, incorporating heavy duty blades of cast aluminium alloy. Blades should be individually adjustable.
5.2 V belt shall be of rubber and pulleys shall be cast aluminium alloy with the grooves of standard dimensions. FRP Belt cover must be provided to protect V belt from moist discharge air.
5.3 Motor(s) shall be TEFC, weather proof, squirrel cage, for 3ph/50Hz/415v power supply and installed outside air stream.
5.4 The complete mechanical equipment assembly for each cell shall be supported by a rigid, welded, hot dipped galvanized steel structural support. Vibration limit switches must be installed to shut off the motor if excessive vibration occurs. The switch is located on the motor end of the mechanical equipment support outside the fan cylinder, so as not to be exposed directly to the discharge air stream and for ease of maintenance and access to reset.

6.0 FILL AND DRIFT ELIMINATORS
6.1 Fill shall be film type, rigid, corrugated PVC sheets that are conducive to cooling water with UV protected and self extinguishing properties. Fill shall be cross-corrugated and the surface of the sheet shall have a suitable micro-structure to improve turbulence and water distribution. Fill sheets shall be bonded at all contact points. Fill shall be of alternate tip configuration to improve water drainage and minimize air pressure drop.
6.2 Drift Eliminators shall be assembled in easily removable modules. Drift Eliminator shall be 3 pass sinusoidal-shaped blade type. Guarantee drift losses must not exceed 0.005% of the design water flow rate.

7.0 HOT WATER DISTRIBUTION SYSTEM
Each cell of the tower shall be equipped with hot water distribution system. Header and lateral pipes shall be PVC. Nozzles shall be non-clogging, capable of passing objects up to 25mm in diameter. The spray must be designed such that the nozzle outlet is the lowest point in the system. The water inlet connection shall be located outside the tower casing. No rotating mechanical sprinkler system is allowed.

8.0 COLD WATER BASIN
The cold water basin shall be of FRP and supported on HDG Steel framework. The basin shall be designed with sufficient water capacity to avoid air entrainment in the outlet during operating conditions. FRP sump(s) shall be provided and equipped with suction strainer, make-up ball valve, overflow and drain. For multiple tower arrangement, equilising pipes between basins shall be provided to maintain the same level of water in each basin.

9.0 ACCESS AND SAFETY
Service and maintenance platform must be constructed at the fan deck level to facilitate easy inspection & maintenance of the fan machinery. Inspection door and caged ladder shall also be provided. Louver panel shall be removable for access to the sump, make up, overflow and suction strainer. HDG steel fan guard shall be provided over each fan cylinder.
