Hi!
There are several titanium-plates heat exchangers in our facility. By one side of the exchanger (cool fluid) runs non-treated water, taken directly from a little dam. By the other side runs treated water that cools an electric generator.
Due to the level variation in the dam, sometimes we...
Hi!
We have several plates heat exchangers in our facility. In a closed circuit, runs treated water that cools an electric generator, and in an open circuit runs non-treated water, on counter flow.
Due to the high quantity of sediments in the open circuit, the thermal flow decreases almost...
Hi!
What methods are there to clean the inside of the tubes of an oil cooler?. The supplier recommends compressed air, not more, but the oil cooler has been working with low quality oil, and it hasn't had an adequate maintenance since it's installation.
¿Are there any chemical solutions or...
Hi!
We need a AC/DC converter, to feed 8 DC motors, 125Vdc - 2 kW each one, from an input of 480Vac. Does anybody know a supplier of this type of AC/DC converters?.
I have found just pc and low voltages converters or low power (12 kW maximum). ¿How much could this cost?
Sorry, if it's a silly...
I have another easy question about fans... well, I hope it is an easy question...
We have in our facility an oil-cooler; it works with two axial blowers, suctioning air through the finned tubes and sending it out directly to the atmosphere.
We could invert the rotation of motor and change the...
Hi!
I want to build an evaporative cooler to increase the efficiency of an HEX (shell & tubes). I was checking the ambiental studies and found the average relative humidity of this area: 81 to 92%.
¿Could I work with an evaporative cooler? I was checking psychrometric charts and the difference...
I have a heat exchanger, (shell & tubes) fan-cooled. It cools oil from 55 °C to 45°C. I would like to increase the net heat transfer with the minimum changes in the system. I have determined the additional heat stream that i need, but don't know how to relate it with the heat exchanger. This is...
