TD42L and TD42H

Thermodynamic Steam Traps

Description

The TD42L and TD42H are maintainable thermodynamic steam traps.
The TD42L is specifically designed for relatively small condensate loads and therefore is ideal for mains drainage applications.
For process type loads the TD42H is available.
For those applications where the release of air is a concern, an anti-air-binding disc is available i.e. TD42LA and TD42HA.
All external body surfaces have an electroless nickel preparation (ENP) which is both energy saving and oxidation resistant.

Standards
These products fully comply with the requirements of the European Pressure Equipment Directive 97/23 / EC.

Certification
This product is available with a manufactures’ Typical Test Report.
Note: All certification / inspection requirements must be stated at time of order placement.
