Panel Heat Exchangers

09/17/2008 5:43 PM

Does anyone have a source for heat exchange panels?

I am looking for a company that can fabricate heat exchange panels. I have found one that may work (Paul Muller) but because of the costs I need competitive bids. Unfortunately the comparative pipe coils cost much less but may not meet the application. The type I am interested in is often used in the electroplating industry. They are made by welding two rectangular plates together around the perimeter. Other spots are welded that hold the plates together in the middle and form channels. The "sandwich" is then inflated under controlled conditions. The results look like a pillow with many "buttons" depressions.

I am also need a service to test my product in a a scale down application with agitation around these panels. The product is a shear sensitive polymer. The smart guys are warning me that the edges of panels may shear the product more than flowing across a pipe cooling coil.

If any anyone has experience with cooling panels in an exothermic reaction with high viscosity (1,000, 30,000, 45,000 centipoise ) I would be interested in hearing.

My application is cooling water inside 40 deg F @ 50 PSIG and exterior 220 Deg F and 0-10 PSIG.

I assume you want to place these inside the reactor...although I can't imagine why. You might want to check McMaster-Carr website or catalogue. They probably have cheap ready-made cooling panels of various sizes and types - not sure if they would be compatible with your process though. I would be concerned about bracing the panels with viscosities as high as you mention...I think I agree with the smart guys

There are tons of heat exchanger mfr for electrical panels.

Try Hoffman Engineering, Kooltronix, look for NEMA enclosure heat exchangers and air conditioners.

Try Tranter at www.Tranter.com

You might also google tranter, and hit "similar results" for competitors.

A few more details are that I do intend to install them in a reactor. Heat duty is 7-10 million BTUs per hour (heat removed).

I am on the road but will investigate the links offered. The big reason is the ability to install and remove individual panels for repairs or reconfiguration through a manway.

A similar reactor with coils would require the roof to be removed, the top F&D head cut off and a coil bundle inserted. Cost to install is > 2X cost of equipment. We know how to do that!

We are too low a pressure to use reflux condensation, External jacketing will remove 7-8% of total requirement.

Any other out of the box thoughts will be appreciated.

Try contacting Alpha-Laval. They manufacture flat plate heat exchangers in many configurations.

Hi Paddler,

I work for a company that manufactured a double helix mixer for the manufacture of high viscosity resins several years ago. The helix was fitted with galleries to enable cooling water to pass throughout the helix to cool the product. The result was exceptional as it reduced the cooling cycle time by close to 40% compared to jackets. We would be keen to quote for this type of equipment if you are interested.

I would consider anything at this point. I have not seen what you refer to in the size or shape needed. Vessel is vertical 12 ft diameter by 14 ft straight side. Estimated surface area internal is estimated 1400 sq ft. Thats a lot of pipe coils or panels inside.

Are you implying that no coils or panels are required just the "galleries" in the helix?

I am interested what it looks like to remove 5-7 million BTUs per hour.
