The Compact ‘PowerPlus’ is specifically developed for high pressure requirements with the Contra-Rotating design that ensures higher performance without increased noise levels and operating costs. The Compact ‘PowerPlus’ comprises three standard sizes - 500, 560 and 630mm diameter - with a duty range of between 1,8 to 4,3 m3/sec and provide static pressures of up to 600 Pa.
The units are suitable for external mounting.
Applications
Areas that are not suited to single stage fans, especially commercial kitchens with higher working temperatures and regulations for greater efficiency in kitchen filtration systems. The Compact ‘PowerPlus is suited for operation in up to 95% relative humidity.
Construction
The all metal fan casing provides a long lasting and robust construction with the units being constructed from a single sheet of steel. Both motors and axial impellers are mounted within the length of the unit casing.< The fan casing is hot dipped galvanised after fabrication. A single terminal IP55 box is mounted on the outside of the casing that ensures easier and faster wiring.
Motors
Motors are lightweight induction motors with sealed for life, maintenance free ball bearings, which allows the fan to be installed at any angle. Each motor is matched to the aerodynamic performance of the impeller. Motors are Class F insulated to EN 60034-5, weatherproofed to IP55 and all suitable for speed control. Each motor has integral thermal overload protection. Fans are suitable for operating temperatures between -200C and +700C fixed speed and -200C and +500C speed controlled.Impellers Adjustable pitch aerofoil impellers are provides with blades made from high quality pressure die cast aluminium (LM6) natural finish with the hubs manufactured from die cast aluminium alloy (LM24). Impellers are factory set at an angle to provide maximum performance.
Assembled impellers are to be dynamically balanced to Grade G6.3.
Testing
The SCPP has been introduced to satisfy the requirements of DW172. Units are to be designed and manufactured with procedures as defined in BS EN ISO 9001: 2000. All SCPP units are to be tested to ISO 5801: 1997 (airside performance) and BS 848 Part 2: 1985 (sound performance).
