TURNING AIR INTO SOLUTIONS. HIGH EICIENCY INDUSTRIAL BACKWARD CURVED ANS MODEL HIB CATALOGUE M0 August 4
HIGH EICIENCY ANS Overview Model HIB Model HIB fans from Twin City an & Blower employ a high-efficiency backwardly-curved impeller in a robustly constructed fan housing. Designed to handle clean air or air with light dust loading, these fans are widely used on the clean side of baghouses, in high-efficiency filtration, forced-draft, and other high pressure process supply applications. The curve below shows the HIB s characteristic high efficiency over a broad range and its non-overloading power curve. Performance ratings shown in the curve are based on tests to AMCA Standard. Standard eatures HIB Arrangement 8 High-efficiency, non-overloading impeller with continuously welded blades and a steel hub Statically and dynamically balanced rotor assembly Heavy duty self-aligning grease lubricated anti-friction split roller bearings Heavy-gauge reinforced housing and bearing pedestal for vibration-free service All fans standard with flanged inlet and outlet, access door, shaft seal, and drain Sizes 60 and larger fans are equipped with a pieshaped split in the casing to permit the impeller and shaft to be removed without disturbing the inlet and outlet ductwork Capabilities an sizes from 80 to Impeller diameters from to,00 mm High temperature construction to 4 C available HIB Design Suitable to 0 m/s tip speed Pressure to 6, Pa HIB Design 4 Suitable to m/s tip speed Pressure to,000 Pa HIB High-Efficiency Backward-Curved Impeller TWIN CITY AN - CATALOGUE M0
ARRANGEMENTS Overview Model HIB Arrangement The usual choice for many V-belt drive applications. Impeller is overhung. Steel bearing pedestal to size 0. Size requires a concrete pedestal. Check with the factory for V-belt drive applications larger than 8 kw. Arrangement SI Single width-single inlet fan with integral inlet box and independent bearing pedestals. The impeller is supported between two bearings. Arrangement SI Arrangement SI is direct drive. Like the Arrangement SI, the impeller is mounted between the bearings. The Arrangement SI includes an integrated inlet box to locate the bearing outside of the airstream. Arrangement Arrangement SI Arrangement 8 Direct coupled with a flexible coupling. The motor pedestal can be custom fabricated out of steel for up to 00 kw. On larger powered units, use of standard Arrangement fan with a concrete pedestal for the motor is advisable. Variations in impeller diameters and impeller widths are available to match design performance at motor speeds. Characteristic curves showing performances at direct drive speeds are available on request. Arrangement SI Arrangement 8 Options/Accessories Inlet Box Dampers Pre-spin design, heavy-duty construction. The damper will spin the air in the direction of impeller rotation resulting in a savings in power at reduced loads. Variable Inlet Vanes Works on the same principle as inlet box dampers. Nested and external type variable inlet vanes are available. Evasé Usually fabricated by customer as part of the ductwork. an outlet must be expanded to equal evasé area shown in the catalog to obtain rated performance. Same gauge as fan housing when purchased from the factory. Temperature and Vibration Detectors Thermocouples or RTDs can be installed on the bearings. Various types of vibration switches are available. High Temperature Construction 0 to 60 C:.... Requires addition of shaft cooler and high temperature grease bearings. 6 to C:.... Above modifications plus high temperature aluminium paint. 6 to 4 C:.... Above modifications plus modified pedestal design. WWW.TC.COM

ENGINEERING DATA Performance Correction for Temperature and Altitude The performance tables in this catalog are based on fans handling standard air at a density of. kg/m. This is equivalent to C at sea level (. kpa barometric pressure). When specified performance is at a density different than standard, it must be converted to the equivalent standard conditions before entering the performance tables. The equivalent standard conditions can be calculated by using the Temperature and Altitude Correction actors from the table below.

Knowing the operating conditions are 0 C and 900 m altitude, the correction factor can be found in the table above to be 0.0.. Divide the operating SP by this factor: 0 0.0 = 6460 Pa SP This is the equivalent SP at standard air density. Derating actors or High Temperature TEMP.

Enter the HIB 40 performance table with 6. m /sec and 6460 Pa SP to find the fan RPM and power in kw. The fan RPM is 40. The absorbed power is 40 kw at standard conditions (40 kw is also sometimes referred to as cold or starting power). To determine the power at operating conditions, multiply the absorbed power (kw) at standard conditions by the correction factor from the table above (40 kw x 0.0 = 0. kw). The absorbed power at operating conditions is 0. kw. Standard steel construction is suitable for use in gas temperatures to 4 C. Aluminum impellers are suitable for temperatures to C only. When a fan operates at temperatures higher than C, the maximum RPMs allowable must be adjusted according to the de-rating factor found in the table at the left. Stainless steel impellers must be derated even at ambient operating temperatures. Please consult factory for stainless steel derating factors. WWW.TC.COM

TYPICAL SPECIICATIONS Model HIB urnish and install as indicated on the plans, Twin City an & Blower model HIB industrial duty backward curved fans. HOUSING an housings shall be made of a heavy-gauge steel with continuously welded construction and braced with structural shapes to eliminate any resonant vibration and provide smooth operation. Sizes 60 and larger shall be equipped with a pie-shaped split in the casing to permit the impeller and shaft to be removed without disturbing the inlet and outlet ductwork. Casing split must be fully sealed and bolted together to prevent any leaks. langed inlet and outlet, access door, shaft seal, and drain shall be provided as standard equipment. IMPELLER Blade design shall be backward curved for high efficiency and have non-overloading performance characteristics. Blades shall be die-formed of special alloy material for strength and accuracy of contour and continuously welded to the impeller inlet cone and back-plate. A heavy steel (not cast iron) hub shall be provided. Impellers shall be shrunk fit on the shafts, and hubs shall include puller holes for use in the event of impeller removal. Impellers shall be statically and dynamically balanced on precision electronic machines, as well as balance tuned after complete assembly. SHAT Shafts are to be solid material selected for AISI 40 or 4 hot rolled steel (or European equivalent), accurately turned, ground, polished and ring gauged for accuracy. BEARINGS ans must be supplied with heavy-duty, self-aligning grease or oil lubricated anti-friction spherical roller bearings with split pillow block housings (bearing races not split) to provide long bearing life. DRIVE Cast iron, fixed pitch sheaves are recommended for best reliability. Variable pitch sheaves can be provided on applications up through kw when specified. Drives and belts are located external to the fan casing and rated for 0% of the required motor rating (kw). INISH & COATING The entire assembly, excluding the shaft, is thoroughly degreased and deburred before application of a protective coating to the entire assembly. The fan shaft is coated with a petroleum-based rust protectant. ACCESSORIES When specified, accessories such as belt guards, access doors, companion flanges, variable inlet vanes, outlet dampers, inlet boxes, inlet box dampers, evasés, evasé dampers, shaft coolers, shaft seals, inlet screens, drains, scroll and side liners, etc., shall be provided by Twin City an & Blower to maintain one source responsibility. ACTORY TEST RUN All fans prior to shipment shall be completely assembled and test run as a unit at the specified operating speed or maximum RPM allowed for the particular construction type. Each impeller shall be statically and dynamically balanced in accordance with ANSI/AMCA 4-96 Balance Quality and Vibration Levels for ans to an Application Category BV-, Balance Quality Grade G6.. Vibration measurements shall be taken by electronic type equipment in the axial, vertical, and horizontal directions on each of the bearings. Records shall be maintained and a written copy shall be available upon request. GUARANTEE Manufacturer shall guarantee the workmanship and materials for its High Efficiency Industrial Backward Curved ans for at least one () year from startup or eighteen (8) months from shipment, whichever occurs first.
