Clean Steam Traps

Staitech HST20, HST30 and HST30TC balanced pressure thermostatic clean steam traps – suitable for a wide range of clean steam condensate drainage, SIP, and system air venting applications in high purity steam systems.

The Staitech HST range of clean steam traps share a number of common design features which include:

  • Near-to-steam operating characteristic
  • 316L stainless steel construction
  • ASME BPE compliant clamp and weld connections
  • DIN and ISO size options
  • Available in low ferrite/low sulphur materials
  • Electropolished finish option
  • EN 10204:2004 3.1 Full component traceability
  • FDA and USP Class VI compliant body seal

HST30

Staitech Manufactured

HST30

The HST30 range of steam traps is designed to remove condensate from high purity steam systems. A thermostatic element is used to detect the difference between the temperature of the cooling condensate and the system operating temperature. When this temperature differential exceeds 3-5ºC the element contracts to allow the cooling condensate to exhaust.

Size Range 1/2″ – 1 1/2″ ASME BPE compliant clamp and weld connections
DN8 – DN40 DIN & ISO clamp and weld connections
Material 316L stainless steel
Options Horizontal inlet connection
Enhanced surface finishes and electropolishing
Alternative materials – low ferrite stainless steel (WN1.4435)
For installations with restricted clearance, Low profile elbows are available in a range of sizes, with both weld and clamp system connections.

HST30TC

HST30TC

Whilst the HST30TC shares the same internals and operating characteristic as the HST30, the body joint is a standard clamp connection. This allows easy strip-down for cleaning or maintenance. It has a higher internal surface finish specification of 0.5 microns Ra. The HST30TC is available with clamp connections in sizes 1/2″ to 1-1/2″. Where space is restricted the HST30TC is available with horizontal inlet.

HST20

The HST20 is a low cost thermostatic trap designed for high purity steam applications. Wetted parts are manufactured from 316L stainless steel with a maximum surface finish of 1.0 micron Ra. The HST20 is available with either clamped (HST20) or screwed body joint (HST20SC).

Size Range 1/2″ – 1″ ASME BPE compliant clamp and weld connections
DN8 – DN25 DIN & ISO clamp and weld connections
1/2″ & 3/4″ twin-lock ferrules
Material 316L stainless steel
Options For installations with restricted clearance, Low profile elbows are available in a range of sizes, with both weld and clamp system connections.

HST20SC

Staitech Manufactured

HST20SC

The HST20SC shares the same internals and operating characteristics as the HST20, but has a screwed body body joint with o-ring seal. This design feature results in one of the most compact high purity steam traps available from any manufacturer.

Size Range 1/2″ – 1″ ASME BPE compliant clamp and weld connections
DN8 – DN25 DIN & ISO clamp and weld connections
1/2″ & 3/4″ twin-lock ferrules
Material 316L stainless steel
Options For installations with restricted clearance, Low profile elbows are available in a range of sizes, with both weld and clamp system connections.

HST50

The HST50 Thermodynamic steam trap is intended for use in constant pressure applications such as mains drainage where space is restricted. The HST50 can be installed in any orientation.

Size Range 1/2″ – 1″ ASME BPE compliant clamp and weld connections
1/2″ & 3/4″ ASME BPE compliant tube weld connections
Material 316L stainless steel
Options Enhanced surface finishes and electropolishing
