ADCABLOWDOWN EXPANSION AND COOLING UNITSBEX DESCRIPTION LIMITING CONDITIONS Minimum operating temperature: -10 °C. Design code: AD-Merkblatt. Remark: Other conditions on request. The ADCA BEX series blowdown expansion and cooling units are used in modern boiler houses to cool hot waste water and steam boiler blowdown before discharging into a pit or drain. The waste water is discharged into the unit, which is at atmospheric pressure, and the cooling water enters through a control valve controlled by, e.g., a thermostat, mixing it with the hot water. If flash steam can not be recovered or discharged to atmosphere, an additional condensing water spray system can be supplied. It is fitted into the top of the unit and can be controlled directly, either by another thermostat, or by the same command used for the automatic blowdown valve control. MAIN FEATURES Prevents thermal pollution. Overflow with siphon breaker. Reduces the flow of flash steam. OPTIONS: Stainless steel construction. Flash steam condensing spray system. Complete system including all the necessary equipment (stop and check valves, thermostats, exhaust head, etc). Manifold with several inlets for multi-boiler installations. Manhole or handhole for inspection. Fitted with support brackets for elevated installation. USE: Boiler blowdown and hot waste water. CONNECTIONS: Female threaded ISO 7 Rp or NPT Flanged ASME B16.5 Class 150. Vertical installation. The inlet of the blowdown tank must always be higher than the boiler discharge valves. Therefore, the connecting pipe should have provisions made at a low point to drain the boiler. See IMI - Installation and maintenance instructions.
