TSS21 Stainless Steel Sealed Thermostatic Steam Tracer Trap
Description The TSS21 all stainless steel steam tracer trap is a completely sealed unit and therefore has no gasketed joints. It is operated thermostatically using a balanced pressure capsule and is specifically suitable for non critical tracing applications. It is however a dual purpose trap in that it can be fitted in the reverse mode where it will operate as a fixed temperature discharge steam trap. The trap fitted in the reverse mode will limit the downstream temperature to approximately 90 °C when discharging to atmosphere. Standards This product fully complies with the requirements of the Pressure Equipment Directive (PED). Certification This product is available with a manufacturer’s Typical Test Report. Note: All certification/inspection requirements must be stated at time of order placement.
