stealthfansTM

Pritchard utilises a family of SmartfansTM which employs a very innovative patented design for the attachment of the blade to the hub. This causes the blade to be almost insensitive to the alternating loads caused by air turbulence or any other exciting factor. As a consequence, the vibrations on the plant structure are greatly reduced.

Vibration problems are generally detected during commissioning when there is limited time available for corrective action which can lead to delays in plant delivery.

FEATURES

The combinations of profile types and number of blades has made it possible to better satisfy specific project requirements in a variety of different applications giving preference either to noise reduction or high efficiency.

The blades, which have adjustable pitch angle, are Easy, Safe and Simple to assemble.

The hub is provided with a conical bushing to shorten the assembly time.

MATERIALS

Special attention has been given to corrosion resistant materials. The hub material is aluminum alloy, airfoil blade profile is aluminum alloy or UV resistant anti-static FRP.

The blade attachment components are hot dip galvanized steel and aluminum alloy.

The fasteners are geomet protected steel with stainless steel as an option. Additional polyurethane coating can be applied to any of the above components.

smartfansTM D Series Fan

Fans from 7315mm to 12200mm with five different blade profile options. Specifically designed for field erected cooling towers, air cooled heat exchangers and air cooled condensers.

smartfansTM STD Series Fan

Fans from 1829mm to 4877mm with four different blade profile options. Specifically designed for cooling towers, air cooled heat exchangers and air cooled condensers.

smartfansTM HD Series Fan

Fans from 3353mm to 7320mm with four different blade profile options. Specifically designed for cooling towers, air cooled heat exchangers and air cooled condensers.

StealthfansTM REM Series Fan

Fans from 1829mm to 12192mm. Specifically designed for high efficiencies with very low noise.

The REM Series is based on a patented technical solution which is the result of a two year research program representing the most advanced product in the field of very low noise axial fans for cooling and ventilation equipment.

The REM series is the only series of low noise fans that, beside the low noise feature offers;

• High efficiency
• Low weight
• Reduced space requirement in axial direction
• Low cost
• Reduced vibration levels

REM Series fans can be supplied in clockwise and counter clockwise rotation. The blades have an adjustable pitch angle and are Easy, Safe & Simple to assemble. The hub has a conical bushing to also reduce assembly time.

The fan blades are aluminum alloy or UV resistant and anti-static FRP. For wet cooling tower applications, the leading edge of the FRP profile is protected by a maintenance free stainless steel sheet. The blade attachment components are hot dip galvanized steel and aluminum alloy. Additional polyurethane coating can be applied to any of the above elements. The fasteners are geoment protected steel with stainless steel as an option. These fans can be used in an ambient temperature from -45oC to +80 oC, with standard materials.
