Cooling Towers and Service
GEA provides all facets of Cooling Tower technology, from new builds, repairs and maintenance of all types of cooling towers. We cater for small pack towers to large mechanical drift units and also supply an large array of cooling tower parts and services.
GEA undertakes all work using quality products and materials designed to meet the arduous conditions encountered in cooling tower environments.
Water Cooling Principles
For maximum working efficiency, a cooling tower must combine three essential elements - a highly efficient packing providing a large surface area for exchange of heat, an even water distribution system and effective drift eliminator.
In GEA towers, we have various types of film-flow packing media available, to give precisely the cooling performance demanded by the specification. Variations in packing design cater for the differences in water purity/contamination in conjunction with minimum resistance to counterflow air. Final choice of packing is in answer to the equation of optimum cooling at an economical cost.
Water Distribution System
The full potential of a cooling packing can be realised only by an even distribution of the water over the entire packing area. In the GEA system, water is evenly distributed through heater and lateral pipes discharging on to the packing by the optimum number of nozzles. Each installation is designed to have the self-cleansing action appropriate to the quantity of water being circulated.
Fans, Motors & Gearboxes
A wide choice of components are available to us, proven by years of experience, to match the performance duties of the tower. Maintenance, vibration, weatherproofing and noise are all criteria that are taken into account, balanced against airflow requirements.
Eliminator are fitted at the distribution level, being a single bank of PVC drift to restrict the carry over to a acceptable precipitation rate.
GIS offer specialist sizing, design to BS 7159, BS6464 for all its distribution pipework manuafctured at the midlands facility. Water distrbution is by a pipe and sprayer, commencing with the main header and a series of latterals distributing the water over the packing. To mininize costs GEA will individually design each header and laterials to pass these savings on to the client
Air Inlet Louvers
To reduce the risk of water carry over, GEA offer an additional safeguard to maximize the control of the water droplet within the tower to mininize any blow through.
Gearbox, Drive Shafts
Gearboxes are fitted to the outside of the fan stacks to allow easy lubrication checks, refills and mechanical works. GEA also offer repalcement units to match the existing equipment. The drive shafts transmit power from the motor to the gearbox. GEA are able to laser align all parts associated with the equipment.
Fan stack are generally replaced with light weight GRP units, however traditional existing units manuafctured from timber can be repaired, replaced or refurbished at our works or on site.
