The CSDT Series is a 316L polished, stainless steel, thermodynamic disc trap, that is compact with a lightweight design and Tri-Clamp end connections. Though non-sanitary in the traditional sense, the exterior is polished to 20 Ra and can be used in clean room environments. The thermodynamic action meets the requirements of quick response and higher capacity applications for plant steam in a sanitary environment. Condensate entry below and concentric to the disc ensures a clean parallel lift of f the seat, minimizing wear. The CSDT is ideal for fluctuating loads and pressures and higher capacity plant steam applications in a clean room environment. It is virtually maintenance free with a one year replacement warranty.
The Mark 93 Series is a balanced port, thermostatic sanitary steam trap designed specifically for use in validated clean steam systems. The sanitary design follows ASME BPE guidelines including a 20Ra μin internal finish, self draining design, and all relevant materials, marking and documentation guidelines. The MK93 has been specifically designed to provide higher flow rates at low pressures and low subcooling levels. In lab testing, the MK93 consistently exhibited excellent flow rates at subcooling levels of less than 3°F or less (<1,7°C). Note: Low subcooling operation insures that condensate won’t back up and wet (cool) the upstream validated temperature sensor.
There are two base designs within the MK93 product range: the standard MK93 – good for differential pressures (P1) up to 50 psi (3,4 bar), and the MK93 Option “P” for differential pressures ranging from 45 – 90 psi (3,1 – 6,2 bar). Both designs are rated to 90 psi (6,2 bar) operating pressure but are recommended for use within the specified inlet pressure ratings. Horizontal connections are now available.
During start-up, the bellows element is contracted and fully open to discharge all non-condensable gas and condensate. The heat of entering steam causes the element to expand, closing the valve. As condensate accumulates in the body, the element cools, causing the bellows/stem tip to retract allowing condensate to drain.
Typical applications include: sterilization drainage for fermenters, bioreactors, separation and filtration equipment, lyophilizers, autoclaves, process piping equipment and steam barriers. Condensate drainage from process systems using clean steam – fermenters, bioreactors, SIP systems and sterilizers.
The Mark 934 sanitary steam trap system is specifically designed to facilitate the sterilization of very large vessels including fermentors, bioreactors and autoclaves without the addition of a SIP Heat up bypass loop. The system consists of a high flow sanitary steam trap and a standard capacity sanitary trap in the same body.
The combined capacity of the two traps handles the highest condensate and air flows during initial heat up, replacing the need for a bypass loop. This trap also manages the lower rate of condensate production during the SIP temperature maintenance period. The Mark 934 is designed to operate up to a maximum differential pressure of 50 psig (3,4 bar) and will control condensate subcooling to less than 5°F, over a range from 10 to 50 psig.
The Mark 93JR Series is an ultra compact, balanced port, thermostatic steam trap designed specifically for use in validated clean steam system for low to medium condensate flows. The sanitary design follows ASME BPE guidelines including a 20Ra uin internal finish, self draining design, and all relevant materials, marking and documentation.
The Mark 93JR has been specifically designed to provide low to medium flow rates at low subcooling levels. In lab testing, the Mark 93JR consistently exhibited excellent flow rates at subcooling levels of less than 3 degrees F or less. Note: low subcooling operation insures that condensate is less likely to back u and et (cool) the upstream validated temperature sensor.
The Mark 94 is a thermostatic steam trap designed specifically for use in higher capacity SIP applications like large filter, and medium to large vessel applications. It features a 20 Ra internal finish, and a self-draining design, to minimize the possibility of medium entrapment and bacterial growth. The Mark 94 has been designed to provide high condensate flow rates during SIP heat up, allowing vessels and other process equipment to reach validation temperature in minimum time. The proprietary fill, bellows and orifice design minimize the subcooling (3°F/-1.7°C) to open the trap during SIP temperature hold, insuring fast drainage under lower load conditions to minimize condensate back up and help insure against validation temperature faults.
As spent condensate and wet steam exit sterilized process tubing or equipment, the SSC rapidly removes enthalpy, subcooling the condensate below it’s saturation temperature. As the cooler condensate enters the sanitary steam trap, it causes the trap bellows to contract. The contracted bellows opens the trap orifice further allowing greater amounts of condensate to exit the system. The finned-chamber geometry of the SSC offers the best available technology for insuring rapid SIP heat-up and uninterrupted hold cycles, while offering a more economical alternative to conventional downcomber designs.
