What preventative maintenance should I perform on my environmental test chamber's electrical system?

There are a number of inspection and maintenance tasks you should complete quarterly on your chamber's electrical system.

Start by inspecting the condition of the chambers and their electrical components:

  • Phasing (for bigger equipment with 3-phrase power)
  • Check the solenoid covers and coils
  • Chamber has at least 3 feet of clearance from the wall 
  • Check the heater and wiring and ground wiring as well as the wiring harness
  • Check the sensor clips and compressor connections
  • Contactors/Relays

If there is an issue with any of the above, take photos of the affected part(s) and send them to support@associatedenvironmentalsystems.com.

Quarterly work must also be performed on the electrical system of an environmental test chamber:

  • Tighten all connections
  • High voltage reading/outside unit
  • High voltage reading on the conditioning system
  • Control voltage reading
  • Compressor amperage reading
  • Heat amperage reading
  • Control switch test (power, heat, cool, and light)
  • Test interior lights
  • Control panel cleaning (vacuum or blow out)
  • Condenser/Evaporator fan amperage

Preventative maintenance is key to keeping an environmental test chamber operational for a decade or more. A properly maintained test chamber can even last 20-plus years.

We understand this is a long list and isn't always manageable to check quarterly, let alone annually. That's why AES offers chamber check-ups. If you're interested in having a chamber professional take a closer look, contact support@associatedenvironmentalsystems.com.
