Components / Spares
We offer a comprehensive range of spares and accessories for all cooling tower types, including fills, motors, drives and nozzles.
Fan Rotating Assembly
IWC supplies a range of fans and fan equipment to retrofit almost any cooling tower or air-cooled heat exchanger.
Our standard fan arrangement comprises an axial flow fan having either fiberglass or aluminium fan blades, right angle reduction gearboxes, steel, stainless steel or carbon fibre composite drive shafts and electrical motors supplied to our customers specifications.
Fan Rings or Fan Stacks
We provide fibreglass fan rings and fan stacks for both air-cooled heat exchangers as well as cooling towers.
These are supplied complete with bell, circular or conical inlets. Pressure recovery diffusers/evasés are available as optional equipment.
Cooling Tower Fills
We have a comprehensive range of cooling tower fills on offer. Our range of media covers all possible cooling tower operating conditions from very clean to extremely dirty recirculating water.
Our fills are typically available in either PVC or polypropylene, with the exception of our splash grid fill that is only available in polypropylene. We also provide different types of trickle fill packs including our NC20. We also offer timber or stainless steel fill options.
A variety of drift eliminators are available depending on the customers emission requirements. These typically include our S-Type (large cooling towers) & Honeycomb D15 (typical in package cooling towers).
Drift eliminators can be provided in a range of materials with PVC and polypropylene being the industry standard. Stainless steel can be provided for high temperature and high fouling applications. EUROVENT certified products can be provided on request.
Water Distribution Systems
We have a range of cooling tower spray nozzles that have been developed by IWC specifically for use in both large concrete cooling towers as well as in package cooling towers.
Square Pattern Sprayers
We offer three types of nozzles that are designed to distribute water evenly in a full cone square pattern with a minimum spray angle of 110°C.
This implies that a single nozzle can be used to cover an area of 1m² with the nozzle tip 350mm above the packing or a square of 1.2 metres at a height of 400mm. The spray nozzles have been designed with profiled swirlers to give excellent water distribution at a low pressure drop.
They cover flow rates of 8 – 35m³/hr between pressures of 1.5 – 6 metres of head. The spray nozzles can be fitted into standard 3” BSP metal or plastic fittings or used with the IWC strap-on saddles. We are also able to offer new distribution piping systems for any cooling tower made from PVC, polypropylene, various grades of stainless steel and other materials.
