The L4000 Series replaceable incandescent pilot lights with associated colored lenses can be mounted to control panels to provide instantaneous status indication of mechanical equipment such as fans, pumps, compressors, or control circuits. In HVAC and building automation systems these are essential for visually indicating fan control, pump control and compressor control. If a project requires multiple panels configured in the same way, consider using Kele's Custom Panel Shop. Experienced panel technicians will assemble the panels according to specifications and drawings. Then, panels are shipped to a desired location. The information is saved so additional panels can be easily ordered on demand. Stop spending time on panel fabrication and let the experts do it.
