Since the beginning in 2007 maintenance and repair of cooling towers are an important part of our activities
Improvement of performance of existing cooling towers.
Often maintenance and repair are used to improve the cooling performance and reliability of the cooling tower
- Installation of energy saving fan blades or improvement air flow
- Use of high performance fill and drift eliminator
- Increase layer of Fill pack
- Motor replacement by high efficiency class IE3/IE4 and/or installation of VSD
- Integration of oil-level switch
- Exchange of fan stack by aero dynamical optimized type
- Modify and upgrade distribution line and spray nozzle
TRANSFER OF EXISTING WOODEN COOLING TOWER STRUCTURES TO LONG LASTING FRP STRUCTURES.
Customers trust in Innovek’s experience in the conversion or replacement of existing cooling towers. Often these conversion projects must be executed in a very short time e.g. during the yearly revision.
Typically, cooling towers with a wood structure are converted to fiber reinforce plastic (FRP). Concrete towers are dismantled and only the concrete basin remains to accommodate the new FRP structure.
Often the cooling performance and the reliability of the tower are improved.
PREVENTIVE MAINTENANCE ROTATING FOR ALL BRAND NAMES.
- Check Tip clearance and Blade angle of Fan blade
- Replacement oil lubricant of Gearbox
- Check alignment
- Re-Torque Bolt/Nut
IMPROVEMENT AND EXCHANGE OF FILL PACK AND DRIFT ELIMINATOR
- Improvement type of Fill Pack and Drift Eliminator
- Change Fill pack and Drift Eliminator
REPAIR AND RECONDITIONING OF FRP FAN BLADES
After the FRP fan blades have been used for some period, the severe damage may be caused by UV Radiation, Impingement erosion and Dew point corrosion on the surface of protective coating ,thus, damaging resin bonded polyester. Finally, the blades will start to crack and break at the stress concentration point ,then , propagate to the other area on the blade.
When these fan blade’s service life is reached, normally about 5-8 years depending on service environment, a number of fan blades are needed to be replaced otherwise poor cooling performance and low plant reliability can be expected. The cost for replacement all fan blades could be enormous and absolutely unnecessary. Presently, maintenance team are becoming more and more important
in saving the plant’s money by applying the latest technology and Know-how available in the industry. PS Coat has a long experience in the development of both advance polymer material and applications know-how to help maintenance people solve the toughest problems.
