Clean Steam

Clean steam is raised from purified water and distributed in stainless steel so that it carries no boiler treatment chemicals, rust or oil to the point of use. This category lists the stainless steel equipment for such systems, almost entirely from Spirax Sarco, with one Yarway steam trap. Seven Star LLC supplies it to pharmaceutical, healthcare, food and beverage sites in Oman.

Thirteen products are listed: a clean steam generator, steam traps, a separator, a filter, an air vent and sanitary valves.

Clean steam equipment in the listing

The Spirax Sarco CSG-HS is a packaged clean steam generator. Downstream, the CS10 separator removes entrained water droplets and the CSF16 filter removes fine particles before the steam reaches the process. Condensate is drained by thermostatic traps designed for clean steam, such as the BT6-B and BTM7, or by the FTS14 ball float trap, and the AVM7 air vent releases air and other non-condensable gases. Pressure and flow are managed by the SRV66 sanitary pressure reducing valve, the STERI-TROL control valve and the M70i sanitary ball valve, with the SVL488 safety valve providing overpressure protection. The Yarway Series 751/761 is a repairable trap for drip and tracer duty on conventional steam lines.

Why materials and drainability matter in clean steam systems

Everything in contact with clean steam is normally austenitic stainless steel, commonly 316L, with a controlled internal surface finish and sanitary clamp or tube weld connections. Components are designed to drain fully so that no condensate is left standing between sterilization cycles. Elastomers and seals are selected for compliance with food and pharmaceutical requirements. Steam quality for sterilizers is commonly assessed against EN 285 for dryness, superheat and non-condensable gases.

Where clean steam is used

Typical duties are sterilization in place of vessels and pipework, autoclaves and sterilizers, humidification of clean rooms and direct steam injection in food production. Hospitals and pharmaceutical plants across the GCC use the same kind of equipment for sterile utilities.

Data to include in a clean steam inquiry

Give the steam pressure and temperature, the condensate load or steam flow, line size, connection type (sanitary clamp, tube weld or flanged), required surface finish and the documents needed, for example material certificates and surface finish records. For a replacement, the product name and size from the nameplate allow us to check the item against the manufacturer documentation.
