Paul Mueller Company PyroPure Pure Steam Generators The Mueller PyroPure P7000 Series Advantage Mueller PyroPure pure steam generators are capable of producing pyrogen-free pure steam that, when condensed, meets all U.S. Pharmacopoeia (USP) requirements for use in autoclaves, critical area humidification, and routine steamin-place (SIP) sterilization. Feedwater enters the system and flows through two level control valves and then into the tube side of the blowdown cooler. In the blowdown cooler, heat is transferred between the feedwater on the tube side and the blowdown exiting the system through the shell side. Correspondingly, the blowdown exits the system at a lower, safer temperature, and the feedwater enters the system at a higher, more efficient temperature. The heated feedwater flows into the steam separator while filling the lower part of the steam separator, the tube side of the evaporator, and the level indicator assembly to a factory-determined range controlled by level indicator switches. At the same time, utility steam enters the shell side of the evaporator. Latent heat from steam is rejected to the feedwater through the walls of the evaporator tubes. The feedwater is evaporated, and the resulting vapor is propelled from the evaporator into the steam separator where any impurities are removed from the steam by centrifugal force. Pyrogenfree steam exits from the top center of the separator and feeds the pure steam distribution system. Simple Design, Reliable Operation • An external evaporator provides improved access for inspection and preventative maintenance on critical o-rings and gaskets. • The separation column contains no internal components that require inspection or periodic maintenance. • All maintenance (including replacement of critical components) can be performed with only 24" of space on all sides (including the top) of the equipment. • Minimal instrumentation is required for equipment operation. Only one control loop is needed which minimizes the calibration required, as well as the potential for downtime. • All components are fully drainable, including the feedwater pump. • All elastomers in contact with feedwater and product are provided with USP Class VI certifications. • ASME BPE certified fittings are used throughout the design. • All product contact surfaces are polished to 20 Ra maximum and electropolished. Surfaces in contact with feedwater are polished to 25 Ra maximum. All surfaces in contact with feedwater and product are manufactured from 316/316L stainl

System Components Evaporator. The natural circulation design of the PyroPure double-tubesheet evaporator ensures maximum surface wetting, eliminating the hot, dry areas that lead to the stress cracking associated with other designs. The tube bundle creates a large heat transfer surface that vaporizes feedwater almost instantly to allow the unit to respond to large loads. Mueller PyroPure pure steam generators have a fully drainable external evaporator, eliminating the need for the excess headroom required for evaporator removal with other designs. All surfaces that come into contact with...

4 Generator performance curves assume no back pressure on the condensate outlet. Any back pressure must be subtracted from the inlet supply steam pressure to figure the net effective inlet steam pressure and actual unit performance. 5 If a feedwater pump is used, feedwater must be supplied at a minimum pressure of 10 psig and connection size may be larger than indicated. 6 Other electrical services must be specified at time of order. 7Dimensions and weights do not include options. All specifications subject to change without notice.

Paul Mueller Company Pressure and Temperature Charts PyroPure Pure Steam Generator Capacity Curves 1. Select the chart(s) with pure steam capacities closest to the one you need. 2. Locate your supply steam pressure on the vertical axis. 3. Follow that line across to the point where it intersects with the curve representing your required pure steam pressure. 4. Drop down from this point to the horizontal axis to determine the model’s pure steam capacity. 5. Select the model which most closely fits your capacity needs given your pressure requirements. Note: Capacities shown are approximate...
