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.

Insulating cover: to prevent the trap being unduly influenced

by excessive heat loss such as when subjected to low outside

temperatures, wind, rain etc.

Integral blowdown valve: a BDV1 or BDV2 can be fitted to the

strainer cap, alternatively the strainer cap can be drilled, tapped and

plugged " BSP or NPT.
