Spirax Sarco BTM7 Balanced Pressure Thermostatic Clean Steam Trap
Spirax Sarco BTM7 thermostatic clean steam trap for pharmaceutical & food processing. 316L SS, self-draining, PN7. Available from P.C. Engineering
Overview
The Spirax Sarco BTM7 is a maintainable balanced pressure thermostatic steam trap engineered for clean (chemical-free) steam systems in hygienic and pharmaceutical applications. It removes condensate with minimal retention while operating close to steam temperature, ensuring efficient heat transfer and system performance.
Manufactured entirely from 316L stainless steel with a typical internal surface finish of 1.6–3.2 µm Ra, the BTM7 features minimal crevices and a self-draining design that meets stringent hygiene requirements. Each unit is individually packaged in an ISO Class 7 clean environment with protective end caps and sealed packaging.
The BTM7 Food+ variant is specifically designed and approved for food contact applications, complying with EC1935:2004 Food Contact Materials and EC2023:2006 Good Manufacturing Practice regulations. Both variants feature a fixed bleed for fail-open operation, ensuring safety in critical process applications.
