KMI Systems, Inc will be featuring its environmental rooms, which ensure that the required temperature and humidity conditions are always present in a powder coating operation. Powder coating booths housed in a well-engineered environmental room with controlled atmosphere are said to significantly increase productivity while providing a higher quality finish. Powder and part production waste is said to substantially be reduced while energy is efficiently conserved.The patented plenum ceiling provides the structure that effectively supplies pressurized air to the environmental room. Conditioned air is introduced into the plenum ceiling and spreads throughout the entire ceiling room. The ceiling bar joists form a slot diffuser system that causes the air to be distributed throughout the environmental rRoom, virtually creating a perfect laminar “soft” flow. This air is then drawn into the entrance and exit conveyor vestibules for recirculation back to the air conditioning system, creating a “closed loop” system.
