Pressure Independent Terminal Units
PITU casings are made from 0.9mm galvanized steel sheet with circular inlet spigot and rectangular outlet connection. The damper blades are double-walled galvanized plate sandwiching a dosed cell neoprene gasket lined with acoustic mineral insulation and black tissue facing which meets 181 standard. This enables better flow management and facilitates low leakage. Cross flow differential pressure sensor (Multi-point averaging inlet type} are used for measuring volume. Shaft indicator is used for damper positioning, Also available are factory fitted and in-house calibrated control components (encased in control panel as an option) viz. actuators and transformers. Rectangular discharge outlet is with clip and drive cleat duct connection, Air flow capacity ranges from 35 - 3776 Ips with minimum inlet static pressure of 20Pa.
They are AHRI certified as per AHRI Standard 880-2011and ASHRAE Standard 130-1996. NC calculations are made based on the procedures outlined as per AHRI Standard 885-2008.
