Yinhe WG055DC Large Environmental/Burn-In Chamber 34.5"W x 39"D x 70"H 480V 3ph

Manufacturer: Yin He

Model: WG055DC

Condition: Used. This chamber is in Fair cosmetic condition.  It is only a few years old, has under 700 hours on the clock, and is pretty clean overall.  Inside the air blowers look clean.  There are some areas with significant scratching, including one ugly spot on the rear door inside.  The top has lots of dust and some rusty edges and mounting hardware.  Several screws are missing from covers.  The controls are high up on the front, away from the risk of untrained personnel making adjustments.  There is a multi-color stack tower light, which is covered in black goo from foam, from storage.

Notes: This chamber is in Good working condition as far as we can test.  We are not 100% sure how to make it run properly, but with the dampers set how the previous owner left them, this unit was only able to get up to 41ºC inside.  We are pretty sure the fans blasting air out the top and rear panel, as well as the ventilation dampers being open, prevented the temperature from rising any further.  It was heating quickly from ambient until it started to slow around the mid-30 degree range.  We set 40º and it settled very slowly as it controlled the last degree...we got tired of waiting after a few minutes and took a picture at 39.9º.  The doors drag the floor with their plastic sweeps, and both front and rear doors close firmly.  The doors leak.  The dampers on the rear panel leak.  The gaps around panels leak.  This is a very leaky chamber.  The rear wall is mostly adjustable dampers to allow air out from the back.  The sides are double-layers of steel but not well insulated; the outside was warm when the inside was warm.  The large, dual blowers provide an extremely powerful and loud blast of air across the chamber at all times.  The START, STOP, and Emergency Stop buttons all work.  The rear chamber lamp switch is a little flaky, it doesn't always stay on when pressed but the lamp does light.  The front chamber's switch or lamp (or both) may be faulty; the front chamber lamp does not illuminate.  The rear panel fans run.  The controllers respond to user inputs as expected.  The hours meter constantly spins.  No other testing was done.
No manuals, cords/cables, or additional items are included if not listed or shown.
