CTI CERTIFIED - VX-S Series

Home CTI CERTIFIED - VX-S Series
 
VX-S Series is an induced draft cross-flow, film filled, FRP multi-cell rectangular cooling tower designed for the equipment cooling, and industrial process cooling and air conditioning applications. The VX-S Series Cooling Towers are specifically designed to meet maximum performance and reliability, and minimum maintenance.
 
The thermal performance of VX-S Series has been certified by CTI in accordance with CTI Standards STD-201. VX-S Series Cooling Towers are designed and provided with high quality v-belt & pulley drive system for trouble free operation.

VX-S Series CrossflowTower Specification

1.0 General
The cooling tower shall be induced-draft vertical discharge type, crossflow, rectangular, film filled, FRP Cooling Tower. It shall be designed with high efficiency drift eliminators to meet current environmental standards and guidelines for microbial control.

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

3.0 PERFORMANCE WARRANTY
The rated capacity shall be certified by the Cooling Tower Institute (CTI). The cooling tower manufacturer shall guarantee that the tower supplied will meet the specified performance conditions when the tower is installed according to plans.

4.0 CONSTRUCTION
The cooling tower main frame structure shall be hot dip galvanised steel (HDG). The casing, louver & fan cylinder shall be made from polyvinyl chloride (PVC).

5.0 MECHANICAL EQUIPMENT
5.1 Fan(s) shall be propeller-type, incorporating heavy-duty blades of cast aluminium alloy. Blades shall be individually adjustable.
5.2 The V-belts shall be of rubber with fabric impregnated able to withstand the adverse ambient conditions of 50°C and 100% R.H. The pulleys shall be cast iron with the grooves of standard dimensions. The entire V-belt & pulley set must be fully enclosed in a FRP molded case to protect the v-belts from in contact with the humid discharge air.
5.3 Motor(s) shall be TEFC, weatherproof sq. caged induction type suitable for 3ph /50Hz/415V power supply and with 1450 rpm.

6.0 FILL AND DRIFT ELIMINATORS
6.1 Fill shall be high efficiency film-type, rigid, corrugated PVC sheets with integral louver and drift eliminator that are conducive to cooling water and UV protected.

6.2 Fills shall be resistance to rot, decay and biological attack with maximum flame-spread rating of 5 according to ASTM E84. Fill module shall be solvent bonded supported from the bottom supporting beam. Hanging fill with structural tubing supported from the upper tower structure shall not be allowed.

6.3Drift Eliminators shall be efficient enough to effectively limit drift loss to 0.005% of the designed flow rate.

7.0 HOT WATER DISTRIBUTION SYSTEM
An open basin above the fill bank shall receive hot water piped to each cell of the tower. Water shall enter the basin through a removable splash box. Removable and replaceable polypropylene nozzles installed in the floor of the basin shall provide full coverage of the fill by gravity flow.

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. The basin shall be equipped with suction strainer, make-up ball valve, overflow and drain. For multiple tower arrangement, equalising pipes between basins shall be provided to maintain the same level of water in each basin.

9.0 ACCESS AND SAFETY
Inspection shall be provided for inspection & maintenance purposes. HDG steel fan guard shall be provided over each fan cylinder.
