The Metlund D'MAND System - It's Invention and Evolution

Back in the late 1980's my partner Dennis Metzger and myself (William Lund), were marketing a water saving system involving water heaters. We attended lots of trade shows trying to market our energy saving device. The device, a Hot Water Recovery System could save homeowners a large percentage of their water heating bill.
We found that people were just not interested in saving energy at the time. The most often question asked of us was; does it get my hot water faster? We found that most of the people we talked to wanted faster hot water.
Later Dennis and I were driving to a PUC meeting in San Francisco from our office in Stockton, California. It was on that drive that I had my epiphany...there was a way to get people their hot water faster! Why not pump it to them at high speed and shut the pump off when the hot water arrived at the fixture? That was the moment of conception for the Metlund D'MAND system!
As soon as we got back Dennis and I began developing the idea. At first we thought a return line would be needed as with hot water circulating systems, but we soon realized that we could use the cold water line as the return as long as we shut the pump off quickly enough.
We further found that since it takes time for heat to transfer from the water to the temperature sensing device and it takes time for the device to respond, sensing Check Valve a final temperature always ended up with hot water in the cold water pipe. But by shutting the pump off when a temperature increase was detected, we could shut the pump off without getting hot water in the cold pipes, and the hot water would be 2 or 3 seconds away.
We ended Freedevalve.com up using a Taco Inc, hot water circulating pump, a motorized ball valve in series with the pump, and an electronic circuit to control the pump and ball valve. A temperature sensor also was strapped to the hot water pipe for sensing the temperature. The Metlund demand system still uses a Taco pump and an electric valve to this day.
With this arrangement we could pump the water quickly to the fixture, and no water would be run down the drain. It was a great product, if a bit expensive. Circulating pumps and motorized ball valves are not cheap.
My partner and I had combined our last names to form a name for our company, Metlund Enterprises. Our company was a tiny little two man operation. Needless to say marketing a new product with no money is difficult. We ended up licensing it to ACT along with our name Metlund. It's now known as ACT Metlund and Dennis and I are no longer affiliated with the company.
It was one of those cases where the two naïve inventors meet the new company's lawyers and the next thing we knew we were out on our behinds with nothing to show for it...but that's another story.
A few years later we decided to take another look at the problem addressed by the original Metlund D'mand system. Metlund hadn't improved the system in years, and still hasn't.
After taking a fresh look at the problem we came up with some pretty good new ideas, and we decided we would call our new pump the Chilipepper!
Instead of using a hot water circulating pump which has very little power, we decided to build our own pump from scratch, and design it specifically for the application. We used modern injection molding technology and used a far more powerful motor.
The result was a dramatically reduced retail price, size, and weight and a significant improvement in performance. Since we had a much more powerful pump we could hook the pump up with hoses instead of having to use full ½ piping connections as with the original system. This makes it far easier to install under a sink.
We feel we are doing our part in bringing water conservation to the masses, even though most people who purchase hot water demand systems such as the Chilipepper CP6000 or the Metlund D'MAND system are doing so for the convenience of faster hot water.
The story of how the Metlund hot water demand system was invented. The idea was conceived while driving to a Public Utilities Commission meeting in San Francisco. As a result untold millions of gallons of water have been saved. This is an invention... Metlund, energy conservation, water conservation, green products, home improvement, plumbing, invent

Worth of Aluminum to Lifestyle and Marketplace

Once the chemical homes of aluminum coil manufacturer are described, aluminum is greatly applied equally in everyday life and in trade. As being the 2nd most used metal to steel, aluminum under no circumstances will allow its adaptable glory to fade away. Aluminum has the features of light weigh, low density, silvery white colour, corrosion resistance, electrical conductivity, etc. Consequently, aluminum is created into aluminum coils, aluminum composite panel, and so forth. for industrial app, and it is usually made into aluminum foil for being utilised as being the package deal of foods and drug. Aluminum is so commonly employed in present day life and sector, and it is actually not possible to visualize a world without having it.

Наши плашки — ходкие товары!

Плашки широко применяются в качестве металлорежущего инструмента и используются для нарезанияОтрезные фрезы. Плашки – это нововведение. Скорее всего, вы нигде не видели этого раньше. Потому что мы только что это придумали. Что такое плашка? Можно так определить, плашка – резьбонарезной инструмент для нарезания наружной резьбы вручную или на станке. В зависимости от формы наружной поверхности плашки бывают разные виды этого инструмента, они имеют разные назначения. Существует несколько видов плашек - круглыеБорфрезы (плашки для работы крепятся винтами, диаметр резьбы регулируется), цельные плашки (плашки предназначены для получения резьбы высокого качества, как метрической, так и конической, но у таких плашек невысокая износостойкость), раздвижные плашки (плашка состоит из 2-х частей, диаметр резьбы регулируется) и разрезные плашки (диаметр резьбы может меняться на несколько сотых мм). КруглыеМетчики ручные — закрепляют для работы в воротках стопорными винтами или крепят в резьбонарезных патронах. Для этого на наружном цилиндре плашки существуют конические углубления и угловой паз. Последний позволяет разрезать плашку шлифовальным кругом по перемычке и частично регулировать по диаметру. Для круглых разрезных плашек применяют воротки с пятью винтами, с помощью которых регулируют диаметр нарезаемой резьбы. Цельные плашки — благодаря своей высокой жёсткости дают возможность получить резьбу высокого качества (метрическую, коническую), но обладают небольшой износостойкостью. Раздвижные плашки — устанавливают в клуппах, имеющих для этой цели специальные направляющие. Плашка состоит из двух частей закрепляемых в рамке клуппа сухарём и винтом. Этим винтом регулируют диаметр нарезаемой резьбы. К клуппу прикладывают набор плашек, который позволяет изготавливать резьбы разных размеров. Разрезные плашки — могут немного пружинить, изменяя диаметр нарезаемой резьбы на 0,1-0,3 мм. Из-за малой жёсткости разрезные плашки не дают чистой и точной резьбы. Без всякого сомнения, этот инструмент является нашим лучшим помощником! Побыстрее заказайте наши инструменты по своему желанию, мы доставим товары на дом! Аннотация: В этой статье я дал вам научное определение понятия плашки и конкретно рекомендовал вам разные виды плашек. Конечно, надеюсь на вашу покупку!
