Mr. Anderson
I would like to take this opportunity to thank you for the good service that your company has provided us with, and the professional approach that has been taken throughout our dealings. We are very happy with the Delta Venturi steam traps that you have installed on all of our kilns and have experienced exceptional performance and durability since installing them over five years ago.
In the past, water hammer was a constant problem on our site which would regularly damage the floats of our ball float traps resulting in the use of costly spare parts and labour as well as unwanted down-time and steam losses. After the installation of Delta Venturi steam traps, we have not had one single problem with water hammer resulting in any damaged traps.Water hammer to a large degree has been eradicated through operator training, but where it has occurred there have been no problems. Thermodynamic (TD) traps which were failing regularly on steam line drip legs but since replacing them with Delta Venturi steam traps we have not needed to replace or repair these traps at all over the last 5 years.
Furthermore, drying times are steady and timeous and we are experiencing excellent results through well dried timber.
Where in the past we were repairing or replacing between 5 and 10 mechanical type steam traps per month, we now do not have to perform any maintenance on the Delta Venturi steam traps at all and do not replace any of these traps at all.
We have also dispelled all the malicious rumours that Spirax and the other mechanical steam trap companies are spreading about the Venturi traps.
We strongly recommend that not only all sawmills and kiln operators, but also all steam users consider converting to the Delta Venturi Steam Trap System.
Yours faithfully,
For, Swartland Boudienste

Subject: Delta Venturi Orifice Steam Traps
This is to acknowledge that Radian Oil & Gas Services had in agreement with Aminat to install eleven pieces of Delta Venturi Steam traps on our D-1540 heating system on 17th April 2013 for a testing period of six months.
Since installation till end November 2013 the traps were performing satisfactorily meeting our severe expectation. The full stainless steel construction with maintenance free concept together with constant discharge principle had reduced the substantial loss of energy and the water hammering effect too.
Aminat will not hesitate to replace any other faulty steam traps in the plant to Delta types.
Please don't hesitate to contact me for any query. Thank you.
Regards,

INSTALLATION OF DELTA VENTURI ORIFICE STEAM TRAPS
When we were referred to your Company by our boiler supplier, we had never heard of or seen venturi orifice steam trap technology. The results of the comprehensive survey that you did made the decision to convert our entire plant, very easy.
For the full year, we have been running on Delta traps, we have seen improvements in process heat- up times, no more water in our live steam and absolutely no more water hammer in our system. Without exception, all Delta traps are performing extremely well and we have not done any maintenance on steam traps at all for a whole year.
We have seen a significant saving in our HFO consumption (35% – R 200,000.00), despite production volumes that have increased.
We appreciate the professional approach and great service you have provided us with over the past year. Thank you also for your willingness to share your technical know-how and experience relating to steam systems.
Looking at our own success story, we can only recommend the Delta Venturi Orifice Steam Trap System to any steam user.
Yours faithfully

WIDI LAUNDRY GERMANY SEES ENERGY AND WATER COSTS TUMBLE AND CO2 EMISSIONS FALL AFTER FITTING DELTA STEAM TRAPS
Dedicated to taking an active role in reducing its carbon emissions as well as saving costs, WIDI Laundry in Lűdenscheid, Germany has seen a dramatic improvement in its efficiency after installing Delta venturi orifice steam traps throughout the plants. Supplied through a local Delta agent, the venturi orifice steam traps have reduced the laundry’s CO2 emissions and its water usage by a remarkable 20%.
Established 40 years ago, a member of the Health Märkische Holding GmbH & Co. KG, WIDI Laundry handles over 30 tons of laundry a day from 60 hospitals and 58 nursing homes. Steam is used as a primary source of energy throughout the laundry in the operation of a wide range of equipment including washers, ironers, collators and dryers.
Conscious that the laundry’s mechanical steam traps were causing water vapour losses through evaporation from the hot well as well as poor condensate return, three years ago Christian Hackler, Production Director at WIDI Laundry asked our local Delta agent to undertake a complete steam audit of the plant.
“We commissioned a complete site survey and were amazed to see that steam losses were estimated at a five figure sum”, said Christian Hackler. “We were also impressed to read that we would receive a payback on the Delta venturi orifice steam traps in as little as 14 months”.
The first installation took place in the boiler house, where Sasha Kohla who is responsible for site services for WIDI Energy GmbH converted all the steam traps to Delta.
“Replacing all the steam traps was easy as they are fully compliant with all DIN standards”, says Sascha Kohla. “After the installation we saw that the operation of one of the shell and tube heat exchangers was not optimised. We were supplied a replacement insert for the Delta steam trap, which quickly resolved the problem. The overall result was very satisfactory as we no longer had live steam leaks and were even able to reduce the number of traps on some of our equipment as the previous installations had not been efficient”.
The remainder of the laundry was retrofitted with Delta venturi steam traps during 2012 and results were immediate:
“Straight after installation we noticed that the steam plume from the condensate receiver almost disappeared. The temperature of the condensate also reduced by 2-3C, which could only be attributed to the leakage of live steam through the conventional mechanical traps.”
WIDI laundry is so satisfied with the performance of Delta steam traps that it has presented the technology to the Leivenst Laundry Group with the suggestion to other group laundries that they also improve their energy efficiency.
The Delta venturi orifice steam traps work by combining venturi technology with the orifice. The capacity of the venturi orifice traps is related to the size of the orifice and also to the backpressure generated inside the venturi. It is a combination of these factors that gives the venturi orifice trap its overall capacity.
As the condensate passes through the orifice there is a pressure loss. On the upstream side of the orifice (the heat exchanger or steam line side), the condensate has the same pressure and temperature as the steam and therefore contains a lot of energy. (It is hot). As it drops pressure across the orifice, the temperature and pressure of the condensate reduce, resulting in it containing less energy. However, energy cannot disappear. So the difference in energy between the high pressure/temperature upstream side and the low pressure/temperature downstream side (i.e. the condensate return system) is converted steam. The higher the pressure difference across a trap (and it is the same for all traps) the more condensate has to be converted into ‘flash’ steam. Venturi orifice technology uses this flash steam to create a backpressure inside the venturi.

Danone Dairy New Zealand
Danone ordered a steam trap for a 10MW heat exchanger for hot water at one of their New Zealand dairy factories. The dairy factory had already installed a number of our steam traps and they were happy with them, so when this application arose, they directed the consultant to specify a venturi orifice steam trap for this new application. The consulting firm was originally looking to use an 80mm ball float mechanical steam trap for this application as they did not have any experience with venturi orifice steam traps. The brief was for the heat exchanger to reach temperature quickly and the consultants were doubtful that the Delta venturi steam trap would be able to respond to the turn up speed they required to meet the design conditions. An agreement was made that stated that if the trap did not meet the design criteria, we would pay for a trap of their choice to replace it. The consultants were doubtful, and what caused even more scepticism was that a 40mm Delta venturi steam trap was supplied for the application with a written guarantee of performance instead of the 80mm steam trap specified. During commissioning the control loop had to be slowed down because the response was too fast. The result: The dairy factory is happy with the performance of the unit and the consulting firm are entirely happy with the trap’s performance as well as the lower cost of the trap compared to that of an 80mm mechanical ball float trap. Needless to say, the consulting firm has confirmed that they will be looking to specify venturi orifice steam traps going forward.

Dear Mr. Verwey
CONVERSION OF CLOVER PAROW PLANT TO THE DELTAVENTURIORIFICE SYSTEM I would like to thank you for your good service and professionalism that your company has provided us over the past nine months. The Delta Venturi Orifice steam traps that you installed throughout or plant about six months ago are performing exceptionally well and we have had no problems to date. We have noticed improvements in heat- up times and water hammer in our system has been eliminated since we converted to Delta traps. Also, our pasteurizer performance is significantly better. The biggest benefit has been the financial one. We have compared our boiler fuel to production volume output ratio for a period after the conversion. Our average monthly fuel saving is 17% as a result of changing to the Delta System. At the current oil price, this is a saving of R286, 000 per year. The actual payback on our initial investment in the Delta Venturi Orifice Traps was only 2.1 months. We are also aware that other mechanical steam trap companies are making claims that Venturi Orifice Traps do not work over varying loads. Varying loads in the steam system is a normal part of our process and the Delta Venturi Orifice Traps are working extremely well in these applications with no backing- up of condensate and no leaking of steam. Based on our own good experience, we can only recommend that not only all dairies but also all steam users consider converting to the Delta Venturi Orifice Steam Trap System

To whom it may concern
In the past we were experiencing problems with our tube heat exchangers splitting and float traps failing on our plant, along with slow heat up times.
Since meeting with Derek from Steam and Process, we replaced 2 traps with the new Delta venturi traps.
The changes were noticeable straight away, no water hammer and everything seemed so much smoother.
Also heat up time was a lot faster.
At the moment we have converted about 90 percent of our plant.
In my view the venturi steam trap outclasses the old technology of a float trap.
Despite what other manufacturers say about this product, I have found them to be excellent.
I would fully recommend converting any steam equipment to Delta Venturi Orifice Steam Traps.

To whom it may concern
It is my pleasure to recommend the Delta venturi orifice steam traps distributed in New Zealand by Derek and Rosalind Cressy’s company Steam & Process.
The marketing information, especially the video, certainly appeared to promise a lot of advantages over that of the more traditional traps and so curiosity aroused, we decided to trial them.
The immediate gain in installing these traps was an instant reduction of noise and flash steam since the venturi has constant balancing occurring of condensate and live steam versus periodic dumps. Clearly pressure fluctuations are reduced which in principle has to be a good thing although we were not aware of any plant issues that were caused by these. Aesthetically, they maintain a good appearance due to its stainless steel construction but commensurate with this is a higher price tag size for size.
While we have not conducted credible performance tests it is easy to surmise that with visibly less flash steam that efficiency would be better than the Thermodynamic traps we chose to replace (purported to be 15-30% better). Considering steam demand savings with the extra cost of these better venturi traps meant we chose to replace our existing traps by attrition rather than wholesale replacement. It is important that the steam is of good quality otherwise the fine mesh strainers in the traps can get blocked necessitating cleaning. Overall we are very happy with these traps and equally happy to recommend them to other would be users.”

Dear Jaques
INSTALLATION OF DELTA VENTURI ORIFICE STEAM TRAPS
When we were first introduced to your energy saving steam traps, we were a bit skeptical as to whether they actually worked as efficiently as you claimed. After receiving feedback from other textile references, we opted to replace only the failed mechanical type traps in our plant with the Delta Traps.
About 50% of our traps in the factory have been replaced with the Delta Venturi Orifice steam traps and we have been running extremely well for about 7 months now, We have seen improvements in process temperatures, heat- up times and we have no more water hammer in our system. All of the new Delta traps are performing extremely well and we have had no problems to date. We have also not needed any maintenance on any of the new Delta traps.
The most astounding result is the saving of HFO which is in the region of 15% month on month, with production volumes being fairly constant over the 4 month period. This immediate saving equates to about R 350,000 per year based on the current oil price. The payback on our investment in Delta traps was about 1 month only.
Thanks for the professionalism and excellent service you have provided us with up till now, and we have decided to replace all our old mechanical traps with Delta Venturi Orifice traps as they wear out and fail.
Thank you also for your willingness to share your expertise and experience relating to the overall steam reticulation system and we certainly recommend you to our other business partners.

Kruger Products is Canada’s number one tissue products manufacturer. They are manufacturers and distributors of tissue products for both consumer, in-home use and commercial, away-from-home use in Canada. Kruger manufactures such consumer brands as Cashmere®, Canada’s best-selling bathroom tissue brand, and Purex®, Western Canada’s #1 bathroom tissue brand. They also manufacture some of Canada’s favourite brands, including SpongeTowels®, Scotties®' facial tissue and White Swan® products. In December of 2015 DSS won the tender to supply over 200 steam traps to Kruger’s Tissue Plant in Quebec, Canada. Project engineer Michel Houde says, “We replaced roughly two hundred steam traps throughout the Mill and the majority of the sizing worked right out of the box. I would estimate at less than 5 % the ones we needed to change the orifice size.” Houde continues, “We had estimated that roughly 20% of our mechanical steam traps had either failed fully or partially open. The project was submitted for approval with an estimated 28 000 M lb steam saving. On record, the best year for steam consumption was in 2012 where we produced 364 000 M lb of steam. In the first complete year of use, we consumed 302 000 M lb, a difference of 62 000 M lb on the historical best.” “Though one other steam project was done over the same fall shutdown, half of the steam savings can be attributed to the replacement of the steam traps alone”. Houde ends off saying, “The traps have worked worry-free since their installation. We’ve had the first annual inspection early this year, and we had to clean no more than 10 units, well under the industry accepted failure rate for mechanical traps. Overall, we have nothing but good things to say about our Venturi steam traps.”
