Packaged Cooling Towers
PLT Cooling Tower Range
The PLT modular range of cooling towers is manufactured in a robust, durable glass reinforced polyester casing.
This range of cooling towers have multiple gear driven fan units and are provided with or without an integrated basin. These cooling towers can be assembled either in the factory or on site (knock down form). These towers are suitable for numerous applications and in the knock down form, lend themselves to be installed in hard to reach area’s such as roofs of buildings, or remote sites.
Components
Casing
The PLT tower is made up of a glass fibreglass-reinforced polyester frame, side sheets and glass reinforced polyester fan casings.
The readily accessible cooling tower fan deck is provided with a non-slip surface and a safety handrail. Access to this deck is by means of cat ladder or staircase (by request). All fasteners are made from stainless steel.
Axial ventilation fan
Each unit has multiple gear driven fans. The aerodynamically optimised blades are made of aluminium or fibreglass, and are adjustable when stationary. A protective grille covers the fan.
Drift eliminator
Profiled plastic elements (PVC, Polypropylene or ABS) prevent water droplets from being carried out of the cooling tower by the air flow.
Water distribution system
Self-cleaning, full-cone plastic nozzles are attached onto the water distribution pipes. These ensure a uniform distribution which is key to the performance of the cooling tower.
Fill
Various cooling tower fills are available and are selected to best suit the process conditions (both temperature and water quality), fill materials are generally either made of PVC or polypropylene but other materials to suit higher temperature applications, are also available.
Cooling components
The cooling components are carefully selected to ensure that there is minimal corrosion and no degradation (rotting).
Dark Room Louvres
The cooling towers are generally supplied with Dark Room type air inlet louvres which are made of plastic (PVC or Polypropylene), and prevent water from splashing out. These can easily be dismantled for inspection and cleaning purposes.
Outlet Strainer
The outlet strainer is attached to the cooling tower outlet, and prevents dirt from entering the water system.
Make-up Float valve
The float valve is connected to the make-up water supply and is used to maintain the water level in the basin.
Advantages
Non-corrosive, long life and light weight
Low energy consumption and easy maintenance due to induced draught fans
Long maintenance intervals and service life
Plug and play design results in simple, economical installation
