Spirax Sarco S7L Carbon Steel Moisture Separator DN15 to DN50 – IBR Certified
Spirax Sarco S7L carbon steel separator for steam, air & gas systems. IBR certified, DN15-DN50, ASME 150/300#. Buy from PC Engineering India.
Overview
The Spirax Sarco S7L is a baffle-type moisture separator engineered for efficient removal of entrained liquids from steam, compressed air, and gas systems. Constructed entirely from carbon steel, this separator is designed for demanding industrial environments where reliable condensate separation is critical to system performance and equipment protection.
The S7L operates by directing the flow through internal baffles that force entrained moisture droplets to separate from the main flow stream. Collected condensate is drained via a suitable steam trap (FT series for steam service) or liquid drainer (CA series for air/gas applications). For steam systems where air ingress is possible, an air vent connection is provided at the top of the separator body.
This product fully complies with Indian Boiler Regulation, 1950 and is available with IBR Certification and manufacturer's Typical Test Report—certification requirements must be specified at the time of order placement.
