Orifice type steam traps? Any views?

Been looking at these Venturi Orifice type steam traps. A couple of companies seem to do them. One Canadian owned company and another from South Africa.

What are peoples views on them? From an energy and maintenance point of view?

This could be an interesting one.. Whenever I have asked Engineers about these types of traps I have had some quite diverse comments. Some loved and some didnt.

We will be doing a future article on different steam trap types, and their pros and cons.

Hi. I have just come across this site and this thread. I work for the Canadian comapny you speak of. What would you like to know about our Venturi-orifice trap?

The project I was looking at for them has been done now. For future reference it would be good to know the sorts of energy savings I could get, and if this is just based on replacing any failed open mechanical traps? Also can they be used on most applications?

Hi. The GEM trap can provide you with between 10-30% savings with a 1-2year payback. 10% against a fully functional mechanical trap and 30% when there are failed open traps. That is normally based on a full site conversions, replacing only failed traps will show a slower saving. We can convert any site that has steam, and nearly all process/applications. There may be the odd application that we cannot size for and that would be because the load is way too varying but that is a very unlikely situation.

Hi all. As mentioned at the top of the page, we are Delta Steam Systems, the South African company manufacturing these products. 
Regarding efficiencies, we have just completed an indepth study at a large US University and have convincingly proven that our steam trap is 9% more efficient than a brand new Armstrong inverted bucket steam trap. Tests also showed that our steam trap was 32% more efficient than what was considered by the university to be a steam trap in good condition, running on their system.
If you require further data on this or about our products, you are welcome to direct message me or get hold of me through our website, www.delasteamsystems.com.

Hi Delta

Are the tests by the US university in the public domain? Just for my own interest I would like to study and read up on it if there is a report?

Hi Big Al

I dont know about Delta but I know that we have studies and reports, not by US Universities but from UK Universites. There are not on the public domian but if you search for 'Performance analysis of venturi orifice steam traps by University Belfast' then you will find several references. I can email you a copy of the report or you can send an enquiry through our website www.thermalenergy.com and someone can send you a copy of some of our reports.
