IUTD30L and IUTD30H

Thermodynamic Steam Traps

with Integral Spiratec Sensors

Description

The IUTD30L and IUTD30H stainless steel thermodynamic steam

traps with integral strainer are fitted to pipeline connectors.

The IUTD30L is specifically designed for lower loads associated

with mains drainage and tracing applications up to 30 bar g.

The IUTD30H is designed for higher loads.

Both traps are fitted with an integral Spiratec sensor for quick and

accurate detection of steam leakage and / or system cooling.

Traps can be supplied with sensors to detect waterlogging and

steam wastage (WLS1) or for steam leakage only (SS1).

All trap / sensor types can be simply integrated into all existing

Spiratec monitoring systems. All trap bodies have an electroless

nickel plated finish (ELNP) which is both energy efficient and

corrosion resistant. The traps are fitted by two screws to a

permanently installed stainless steel pipeline connector to

ensure the maintenance is both quick and easily undertaken.

Traps can be removed / replaced using a simple wrench with

minimum system downtime.

Optional extras

The IUTD30 can be fitted to a variety of pipeline connectors:
