Spirax Sarco BTM7 Stainless Steel Thermostatic Clean Steam Trap

Spirax Sarco BTM7 Stainless Steel Thermostatic Clean Steam Trap

The Spirax Sarco BTM7 is a maintainable thermostatic steam trap designed to remove condensate from clean steam systems with minimal backing up. Applications include sterile steam barriers, process vessels and CIP/SIP systems. Manufactured in 316L stainless steel with minimal crevices, it is self-draining and operates close to steam temperature. Traps are individually packaged with protective end caps and sealed in a polythene bag.

Fixed bleed to ensure fail open operation Special connections to suit most piping systems.

For use on systems where there is, or maybe lactic acid present an FEP encapsulated silicone 'O' ring is recommended and available.

Certifications

This product is available with certification to EN 10204 3.1. Note: All certification / inspection requirements must be stated at the time of ordering.

Installation note:

The trap is designed for installation in vertical lines with the flow downward to ensure self-draining operation. Do not expose element to superheat conditions since over-expansion may result. Suitable isolation valves must be installed to allow for safe maintenance and/or replacement.
