ADCA AUTOMATIC AIR AND GAS VENTS FOR LIQUID SYSTEMS AE45.2 (Stainless steel 1” x 1/2”, 1” x 1”; DN 25 x 15, DN 25 x 25) DESCRIPTION The AE45.2 range of automatic vents are designed to remove air 1 2 or gases from water and other liquid systems, without requiring any 3 4 external source of energy. 5 They are capable of handling significant loads during start-up while 6 still being able to discharge smaller loads in continuous modulating 7 operation with one single orifice. These ball float type vents are manufactured in stainless steel, available with soft sealing, and can be used in combination with other air elimination and separation systems or directly applied at high points in the pipelines. MAIN FEATURES Suitable for start-up and continuous operation with one single orifice. Allow fast and easy inline maintenance. Corrosion resistant internal parts. No balancing pipe required. OPTIONS: Metal to metal sealing. Threaded connection on cover, closed with plug. HVV – Hand vent valve. USE: Cold, hot and superheated water or other liquids compatible with the construction. AVAILABLE MODELS: AE45.2-6, 14, 21 and 32 – stainless steel. SIZES: 1” x 1/2” and 1” x 1”; DN 25 x 15 and DN 25 x 25. CONNECTIONS: Female threaded ISO 7 Rp or NPT. Flanged EN 1092-1 PN 40.

ADCA NOISE DIFFUSERS DF DESCRIPTION The ADCA DF series are compact noise diffusers designed to disperse the high-speed discharge from steam or air traps, dampening the noise levels and reducing erosion. These devices are typically installed downstream of intermittent steam traps, such as thermodynamic or inverted bucket, which are generally associated with high-speed blast discharges. Noise reductions greater than 80% can be expected when measured at 1 meter away from the source. MAIN FEATURES Simple and compact design. SW No moving parts. A Noise reduction greater than 80%, measured at 1 meter away from the source. ØB USE: Steam or compressed air. AVAILABLE DF15 – outlet with threaded connection, suitable MODELS: when discharging to condensate return lines. DF16 – outlet without threaded connection, suitable for direct discharge to atmosphere. SIZES: 1/2”, 3/4” and 1”. CONNECTIONS: Female threaded ISO 7 Rp. INSTALLATION: The recommended installation position is vertical with the outlet connection pointing downwards to the ground or to another safe place. Clean the system thoroughly before installing the diffuser. In compressed air systems ensure the system is free of oil. See IMI – Installation and maintenance instructions.
