Used BALZERS BAK 550 #293661192 for sale

BALZERS BAK 550 is an evaporator designed for removing moisture from liquids and gas streams. This evaporator is capable of reducing close to 100 percent of the moisture from the feed stream typically to levels of 0.1-0.3 percent relative humidity. The presence of bare metal surfaces makes the evaporator highly efficient at removing moisture from gases and liquids. BAK 550 evaporator has a hollow cylindrical shell made of stainless steel and provided with a removable cylindrical cap. Inside this evacuated chamber is a rotor made of sintered stainless steel. This material ensures optimum heat transfer throughout the process as well as extremely low contact temperatures so that the feed stream is heated to the desired level without any damaging thermal effects. The rotor consists of an inner chamber and two seals. Vertical baffles are integrated into the inner chamber, which guide the liquid through multiple passes as it is subjected to evaporation. The feed stream flows over the rotor surface and forms a thin film of liquid on the rotor, which is then exposed to the vacuum created within the chamber. This causes the liquid to be vaporized, and the moisture is then pulled away by the vacuum. The evaporated liquid is condensed and collected. The liquid loading of the evaporator can be adjusted accurately allowing the feed flow rate to be regulated, ensuring all moisture is removed. BALZERS BAK 550 evaporator has an operating pressure of between 0.001mbar and 0.25mbar and a maximum temperature of 280°C. The evaporator offers a number of safety features and can be connected to a variety of other instruments in order to monitor and control the process. Remote control is integrated with the evaporator, allowing the operator to control and monitor the process without the need for direct contact. BAK 550 evaporator is suitable for the evaporation of organic liquids, aqueous solutions, and process waste streams. This evaporator is also suitable for applications involving catalytic reforming, crystallization, and water ultra-purification. The highly efficient and robust design of BALZERS BAK 550 makes it an ideal choice for industrial processes that require minimum moisture removal.
