Q. We are looking for some spare parts for an "environmental chamber - metal finishing equipment" manufactured by "the Harshaw Chemical Co." in Cleveland, Ohio. We cannot get information about that company and we need to repair the environmental chamber.

Model: 21 Serial:

If somebody can help us we appreciate it. We need information as soon as possible.

A. Hi Jose. Although Harshaw Chemical Co. is now part of Atotech, the Equipment Division, which manufactured the salt spray cabinets, was spun off as Auto Technology in Strongsville, Ohio. That's probably who you're looking for :-)

Salt spray cabinet qualification requirements?

Q. Is there a published specification for calibration or qualification requirements for Salt Spray Cabinet and Humidity Cabinet equipments? We need information for requirements as per ASTM Standard or ISO Standards Or any other standard.
Example: Salt Spray Cabinet equipment or Humidity test chamber unit must be calibrated once a year or once every 2 years.

Q. We recently purchased a salt spray chamber and we are working to get a certification of the ISO 17025 [affil link] for the laboratory.
Does this certification standard require a calibration of the pH meter, hydrometer and thermometer?

In addition, do the collectors have to be on the same level as the samples?

Finally, How do you clean the chamber to eliminate the rust?

Thanks a lot for your help.

Salt spray chamber repairs?

Q. I have an Auto Technology chamber and it will stop fogging after 2 hours. We have done everything in our power to have this gone through and looked at by an engineer. I have tested the solution, installed a rebuild kit and everything. All and any advice would be great.

RFQ: Does anyone know who is in the WI area that works on these chambers? For the cost of having the Auto Tech come to WI I can buy a new chamber.

A. Was a new atomizer included in the rebuild kit? They're difficult to keep clean.
Check your bubble tower: does it have buildup on the walls?
Dilute HCl cleans the buildup off nicely. Rinse it off well.
The bubbler at the bottom of the tower could be clogged as well.
Check all air fittings to ensure no leaks.

A. Have you tried looking for debris in the atomizer? I had a similar issue a few weeks ago and it ended up being a spec of something was blocking the inlet for salt water.

RFQ: We have the same unit and can't find anyone to repair it due to the age. I would really appreciate any contacts for repair of a chamber.

A. Hi K. Decades ago I worked for Harshaw Equipment Division which built those cabinets (the division was spun off and is now Auto Technology). When we repaired old PVC-lined steel salt spray chambers it was often a very expensive job because, after decades of very corrosive solutions leaking under the lining, after stripping the lining and trying to rebuild the shell with its double wall, inspection window coping, etc., there often just wasn't much worth saving. So good luck if you have an old PVC-lined steel one :-)

A. We had an old model 21 Harshaw chamber that rusted out. We had a new enclosure made out of 3/8 thick polypropylene sheet heat welded together. It was built just like the original design with the double walled water jacket. We kept all the original hardware and controls. We have been running it continuously for probably 15 years now with no problems.
