Vortex Cabinet Coolers - Keep Your Electrical Enclosures Cool…
Vortex Cabinet Coolershttp://www.fiktech.nl/pages/012-prod...coolers-en.php
Today’s small and compact, multi-function electronic controls,variable speed drives, servos and programmable logic controllers are extremely sensitive to heat and contamination. Smaller cabinet sizes make temperature control difficult and contribute to significant premature failures. Excessive heat causes components to “cook”, digital displays to misread, controls to drift, and breakers to trip below their rated loads. The result is often lost productivity from machine or line shutdowns. Fans often provide inadequate cooling and commonly pull in dirty, humid air creating another source of failure. Air conditioners require ongoing maintenance and are relatively expensive, large and difficult to install.
Vortex Cooler Enclosure Coolers are the affordable, low maintenance easy to install alternative for keeping enclosures cool and clean without Freon or other refrigerants!

Re: Ash Hopper / Screw Feeder Displaced Air
Assuming hopper is fed by a pneumatic conveyor the Filter needs to be sized on the amount of conveying air coming into the hopper. The air displaced by material will be negligible as compared to the conveying air. ■
Re: Ash Hopper / Screw Feeder Displaced Air
Itis not pneumatic its is a fully skirted and covered trough belt conveyor. ■
Re: Ash Hopper / Screw Feeder Displaced Air
If it is ash on belt conveyor then we again has to assume it is wet.
Dry ash on belt conveyors is not a good solution in my opinion.
If it is wet then you can assume it is non dusty product and you
will not need a slight vacuum in the hopper to keep the dust inside.
The displaced volume of air will be equal to the volume of material into
silo which is 33.33 m3/hr based on density of 1200kg/m3. This vol of air
will easily decipate through the belt conveyor interface and it is very unlikely
that it will cause over pressurization. But if you are worried then you can put
a PRV / VRVon the hopper. They are cheap and cheerful.
If it is dry ash then you will need a fan assisted filter to keep the dust in. The fan
size will depend on the hopper volume. If putting a fan then you will require a PRV / VRV
as then you will have a real chance of vacuum build up. ■
Ash Hopper / Screw Feeder Displaced Air
Hi,
Hope someone can help me with this problem or give me some guidance. Im fairly new in the materials handling game but eager to learn.
I have a fully enclosed hopper with screw feeder fixed to the outlet. This hopper will be fed Ash (1200Kg/m3) up to a max rate of up to 40 tons per hour. This will not be a constant flow it will come in one slug or slugs of Ash i.e. 40 tons could come in a small period but overall the max will be 40 tons per hour.
The hopper which is a pyramid design has a volume of 75m3.
Ash Bulk Density = 1200kg/m3
Fill rate up to 40 Tons/Hour
My question is to with the displaced air.
What exhaust air flow rate is needed to get rid of the displaced air so an over pressurization is not caused.
We are going to put a spigot on the hopper from which to extract the displaced air. I just need to size this according in order to extract the correct amount of air.
Thanks Shaun ■
