Solid Drilled IDF/ISS Hygienic Thermowell

Product ID: HTW130

The HTW130 solid drilled IDF/ISS hygienic thermowell is suited to applications involving high pressure and flow rates. This style of thermowell is manufactured from solid bar-stock to ensure strength and integrity and is available in 316 stainless steel.

The HTW130 thermowell is available with either a parallel or tapered stem profile and has a wide variety of IDF/ISS process connections available. The instrument connection can be specified with a BSPP, BSPT or NPT thread which allows for easy installation of an RTD or Thermocouple temperature sensor.

In order to determine or prove the suitability and required dimensions of a thermowell based on the process conditions, we offer wake frequency calculations as per ASME PTC 19.3 TW-2016. In addition there are a number of other certification and testing services available including 3.1 material certificates, pressure testing and positive material identification (PMI).

If the options provided by our industrial range don’t meet the precise requirements of your application, call our experts on +44 (0)1243 866 866 for a no-obligation consultation about a bespoke solution.
