 Sanitary Steam Trap System > Mark 934 Series



Mark 934 The Mark 934 sanitary steam trap system is specifically designed to facilitate the sterilization of sanitary 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 condensate capacity of the two traps handles the highest condensate and air flows during initial heat up, replacing the need for a bypass loop. The standard integral trap manages the lower rate of condensate production during the SIP temperature maintenance period.
Mark 934 Value Proposition
1. Capital Expense (CAPex) Reduction: Piping simplification: Elimination of bypass tubing, tubing components, 3-way valve, and I/O capacity. And, minimization of associated labor: welding, polishing, wiring and commissioning.

2. Utility Cost Reduction: Efficient air and condensate drainage without live steam or pressure loss. All available heat is transferred to the vessel, not the drain.

3. Vessel Availability Increase: More efficient heat transfer increases bioreactor or fermenter availability by reducing heat-up time and SIP total cycle time.
