Reliability and avoiding downtime are some of the most important goals for any electrical enclosure application. To achieve this, enclosure air conditioners that are used need to protect electrical equipment from the adverse temperatures and conditions that are encountered. To accomplish this, there are several best practices that customers should expect to receive from their special-purpose air conditioner manufacturer:

1. Utilization of an integrated 3D design system to ensure the dimensional compatibility of component parts and to make sure that the largest rated cooling capacity unit occupies the smallest functionally feasible footprint.
   
   
2. Have environmental lab testing equipment to ensure every air conditioner achieves its rated capacity under a variety of conditions..
   
   
3. Have a UL (Underwriters Laboratories) certified laboratory that provides safety assurance as well as piece of mind that the air conditioner or other cooling units comply with all current electrical safety standards and regulations.
   
   
4. Comply with RoHS (Restriction of Hazardous Substances) regulations to guarantee specific harmful substances will not be utilized in the products manufactured.
   
   
5. Use of paperless manufacturing procedures to ensure final product uniformity and latest revision control.
   
   
6. Utilize automated fabrication and robotic bending machinery which allows for accuracy and repeatability, yielding finished products of consistent quality.
   
   
7. Use continuous formed tubing equipment that will eliminate nuisance refrigerant leaks caused by excessive solder connections. Kooltronic uses a triple refrigerant integrity test process for vacuum, pressure and leak detection. The elimination of refrigerant or air vacuum leaks preserves the compressor’s efficiency, contributes to a longer compressor life, maintains thermal performance, and reduces maintenance and repair costs.
   
   
8. Utilize automated wire crimping machinery capable of power crimping and auto-inspecting electrical terminations which help to prevent premature compressor failure on voltage drops that can occur when loose connections exist.
   
   
9. Utilize a form  gas mixture of hydrogen and nitrogen to test pressure integrity,  refrigerant flow rate and leak testing via mass spectrometry ensuring performance over the life of the unit.
   
   
10. Use a computerized, bar-coded evacuation and charge system. Kooltronic uses a deep vacuum process to remove any dissolved water vapor from the refrigeration system. A contaminant free system will also extend compressor life.
    
    
11. Perform final operational testing of the entire air conditioner, verifying its electrical safety and thermal performance.
