Mechanical Parts

Axial Fans

Axial fans drive a cooling towers performance and are subject to extremely high stress during system operation.  As a rotating "high speed" piece of equipment, it is critical that the fan components are regularly inspected for cracks, fatigue, corrosion and operational damage.

Fan failures can cause large amounts of damage internally to drift eliminators, fan cowls and distribution components.

We can supply fans of all sizes to suit your cooling tower, condenser or fluid cooler.

Centrifugal Fan Wheels

Our centrifugal fan wheels are specifically designed for evaporative cooling equipment and are available in galvanized mild steel and 304 stainless steel construction.  Powder coating of galvanized fan wheels are also available. 

Wheels feature a welded, riveted and press tab construction with grub screw and clamp lock hubs to ensure proper wheel hub to shaft contact and reduced wheel slip.  They feature a forward curve design and are dynamically balanced for perfect vibration free operation.

Fan Motors

Fan motors are available for both direct and belt driven units.  Motors are MEPS compliant, have a 2 year warranty, can be epoxy coated and have double sealed bearings.

They are designed for the harsh operating conditions of evaporative equipment applications incorporating design features that ensure reliable performance in 100% humid operating environments.  Standard and extended shafts are available as is standard and high efficiency.  IP56 rating is standard on all motors.  Motors are available from 0.37kW up to 45kW.

Aluminium Pulleys

Pulleys are manufactured from high grade aluminium alloy.  Aluminium pulleys are superior to cast iron alternatives commonly used in evaporative cooling equipment as they offer better corrosion protection.  Cast iron pulleys can suffer from localized rust on drive grooves that damage belts and advance belt wear.

Aluminium pulleys do not experience this problem and the result is longer service life of drive belts, less drive belt maintenance and extended periods between drive belt replacement.  Aluminium pulley retrofit kits are supplied with power band belts which are constructed of neoprene with polyester cords.

Bearings

Cooling tower bearings are commonly subjected to overloading, fatigue failure, lubricant failure and corrosion.  Internally mounted bearings are exposed to water drift, condensation and high temperatures which contribute to reduce bearing service life.  To prolong bearing operation it is important that bearings are regularly inspected and greased.

We offer a full range of bearings to suit your cooling tower, condenser or fluid cooler.

Automatic Grease Canisters

Our grease canisters provide up to 6 months automatic dispensing of grease for bearings.  We also supply grease lines and fittings. The grease is resistant to water wash out, shock loading and pound out.  

The cartridges have very good pumpability at low temperatures and the high dropping point permits operation at higher temperatures.  Distinctive colour shows when fresh lubricant forces out old material.  The adhesiveness causes grease to cling and protect metal surfaces.

Fan Shafts

Tubular shaft
Tubular Fan Shafts feature forged journals and are foam filled to reduce vibration. Mild Steel shafts are coated in ZRC Coating to protect them from rust and are supplied with mild steel stepped steel key steel.

Solid Shaft
Solid fan shafts are manufactured from a solid piece of centreless ground shaft material, shafts feature end keyways and for some shafts centre keyways and grub screw depressions machined into the shaft.

Step Shaft
Stepped Fan Shafts are manufactured from a solid piece of material and feature keyways and threaded sections to assist with locking fans to the shaft (where required)

We offer a full supply and installation service for all parts to suit your evaporative equipment.
