Project Number 1

Summary:

Ultrasonics did not yield promising results. Media blasting with baking soda did have better results.

Test Objective:

To find a more effective way of cleaning our support screens
Trial Number Date Run Purpose Success Rating
0 05/08/1996 Goal of trial is to find a cleaning method Results successful using TACT (time, agitation, concentration, and temperature, as well as rinsing and drying) and/or other cleaning chemistries examined.
1 05/13/1996 Results of Requested Testing Results successful using TACT (time, agitation, concentration, and temperature, as well as rinsing and drying) and/or other cleaning chemistries examined.
2 06/10/1996 Update on feasibility of using ultrasonics Test showed little or no promise.

Project Number 2

Test Objective:

Replace toluene for prepainting preparation.

Product Use:

parts are used to build small rooftop size dehumidifiers
Trial Number Date Run Purpose Success Rating

3 10/28/2009 To evaluate top five products on third supplied contaminant using manual cleaning A follow up test, usually based on company input.
4 11/03/2009 To evaluate top five products on fourth supplied contaminant using manual cleaning A follow up test, usually based on company input.
5 11/05/2009 To evaluate top five products on fifth supplied contaminant using manual cleaning A follow up test, usually based on company input.
6 11/04/2009 To evaluate top five products on sixth supplied contaminant using manual cleaning A follow up test, usually based on company input.
7 11/04/2009 To evaluate top five products on seventh supplied contaminant using manual cleaning A follow up test, usually based on company input.
8 11/12/2009 To evaluate top five products on eight supplied contaminant using manual cleaning A follow up test, usually based on company input.
9 12/16/2009 To clean company supplied parts with the 5 most effective cleaners found during lab trials Results suggest a scale-up feasible match for cleaning chemistry and equipment. Pilot plant study with actual parts recommended.
