Application:
Walk-in Environmental Chamber is designed for environmental simulation to test perfomance and reliability of communications, electronics, automotive, pharmaceuticals, aerospace and other related products. It has panelized construction and solid construction which depends on the inner dimension and request for relative humidity.
Drive-in Test Chamber for mobile, LCD monitor & Notebook is one of our top specialty. A major computer manufacturer requires a Walk-in Aging Chamber to test several racks of servers at the same time. A full load of servers can generate over 10 kilowatts of heat, which can cause problems with uniformity, so LABTECH recommended a ceiling air plenum for Drive-in Test Chamber to distribute the air.
The panels used in our Walk-in chamber are 100mm to 120mm thick urethane-foam sandwiched between a stainless-steel interior wall and a coated-steel exterior. An assembled box is self-supporting, so that no heavy structural members are required different door size, access ports, and other modifications are possible.
