1. Can Steamloc be applied on all kinds of applications?

Over the years Steamloc has proven to be effective for practically all applications. Whether it is for a Petrochemical or Chemical plant, Food Industry, Waste treatment, Textile, ... Steamloc works well on the process applications but also for utility applications. We experience that our clients tend to focus on process applications first. This is logical because here Steamloc will make the largest difference in efficiency. The heart of your production will be free of unpredictable problems. As a next step, clients continue to converts utility applications to save on energy losses and maintenance costs and spares.

2. Is Steamloc limited in capacity and pressure?

There are no limitations for ranges of pressure drops and capacities. We can always provide a suitable Steamloc for every application. Of course a positive pressure drop is required to remove condensate - for both mechanical traps and Steamloc. Using older technologies large process applications require level controllers or parallel trapping to remove the high condensate loads. With all piping/valves/inspection/ ... that comes with it. Steamloc perfectly handles this with one unit in lineair piping - easily insulated for safety.

When necessary, special alloy material can be used to meet conditions of extreme pressures and corresponding temperatures. In fact there are no limitations. The internal venturi construction is always calculated and mounted for your application as a one time only action. After start-up, Steamloc is ready for a life time condensate removal. Pressures to 130 bars are no problem. But more important are the applications with very tiny pressure drop. Even a pressure drop of 0.05 bar suffices for Steamloc. This is where f.i. floating traps not even open due to their working principle.

3. Do all condensate removal devices consume live steam?

Until venturi technology appeared, we did not bother too much about steam consumption. Steam traps were sold as a kind of valve that would be open for condensate and closed for steam. Possible failures were seen as normal and repaired or replaced (when the location of the leak could be established).

All systems on the market are subject to energy losses. These can origin from heat transfer from the available surface, or as a result of the various working principles. For example:

  • The collector vessels of level controlled systems are subject to heat losses.
  • Thermodynamic traps open at given times, regardless if condensate is present or not.
  • Thermostatic traps pass steam just before the higher temperature makes them close.
  • Logically also steam passes when high loads of condensate whirl through a floating trap.

In fact, it was accepted that all systems that are related to condensate and steam consume energy, but not much attention was given to that fact.

Our company has never claimed enormous energy savings from the operational working conditions of Steamloc. It is not better or worse than other steam traps. But what we do guarantee is the energy consumption will be constant and negligible over years of operation.

Most important is the fact that it can not fail open suddenly like conventional steam traps can. For this reason, Steamloc is always more energy friendly than mechanical traps. Remember: replacing a failed mechanical steam trap will always be much more expensive than having installed Steamloc from the beginning.

4. Will Steamloc be subject to erosion after years of operation?

When Steamloc is designed according the actual data of your application, there will be no erosion, even after 25 years. The answer is found in the two-phase flow through the Steamloc. Two things are necessary to create erosion with steam and condensate:

  • High velocity.
  • Two-phase flow conditions with primarily steam and additional few small particles of condensate.

This is best demonstrated with a steam leak. In little time the leak becomes bigger and bigger due to the high velocity of steam flow incorporating a small spray of condensate that blasts the opening.

Steamloc® venturi-nozzles will not operate under such conditions because they are calibrated for the given condensate loads with a very small amount of steam present. The condensate keeps the velocity relatively low, while the water itself does not cause erosion as a function of time.

5. Can Steamloc work under negative pressure condition?

In case of negative pressure difference no condensate is removed, not by steam traps, not by Steamloc. Condensate can flow back into the application, which can be restricted by a check valve.

As a solution to drain such conditions one could install atmospherical discharge to temporarily collect condensate or one could use a pump behind Steamloc. Steamloc handles all positive pressures while the pump takes over for the negative ones. A benefit for this line-up is the protection of the pump - it never has to deal with the high pressure condition which obviously improves the pump life-time.

6. How can Steamloc handle pressure and condensate load variations?

The most logical example we find at every start-up condition. The wide condensate range permits Steamloc to handle these maximum loads in a time that is competitive with mechanical systems, even if they have start-up pressure drops (low).

Other variations are initiated by the process itself. Steam flow rates and therefore condensate rates can vary depending on required production capacity. This is normal. Such processes usually have control valves at the steam inlet. Higher steam flow to meet the requested higher temperature results in higher pressure in the equipment. Since Steamloc capacity is pressure dependent it can follow these variations very well. In fact Steamloc operates perfectly in conjunction with the control valve.

For process applications that work with other types of controls and variations in steam/condensate flow, like batch processes, the wide condensate range of the Steamloc with constant pressure will allow to operate also at these conditions. For more details we suggest you contact us

7. Can your company provide sufficient support for my applications worldwide?

The whole concept of Steamloc® is based on the fact that it requires no maintenance. Steamloc is fully warranted and can easily be modified to new conditions. In event quick action is needed we provide new internals by Courier. These can be replaced easily at plant site personnel. To make the calculations available to engineers, we have sizing software available on the website

Steam trap support is worldwide to deliver spares to restart your suffering production plants ASAP. Logical you want them to be near.

No mechanical parts make Steamloc a unique tool that can be installed to work for an unlimited life time. Steamloc first installed in the 80's are still in service. This might be a better alternative perhaps than you are used to.

8. Which data is required for a correct Steamloc sizing?

Steam pressure, condensate return pressure and condensate load are sufficient. In addition the physical dimensions (size, rating, schedule and built in length) would be of help. Engineers can download an example data sheet or request one by mail.
