Leister 230V 3300W LHS 21L SYSTEM Air Heater - 140.461
Details Productive air heater
The LHS 21L SYSTEM is a step further in the development of the tested and proven line of Leister air heaters for production processes: As with all SYSTEM process heating devices, the LHS 21L SYSTEM features direct connection to a PLC control system and offers system designers and production managers even better control and functionality. The system works in ambient temperatures up to 65 °C (149 °F) and the heating output adjustment is continuously variable up to 650 °C (1202 °F). This can be controlled by a PLC or stand-alone controller via a 4 - 20-mA signal or 0 - 10 V interface.
Decades of experience in plastics machining and industrial processes have also flowed into the development of the LHS 21L SYSTEM. The compact design has a total width of 67 mm (2.64 in) and facilitates integration into production lines with external control systems. In addition, the SYSTEM line of new industrial heating systems features a digital temperature display on the tool itself, enabling immediate control of the nominal heating temperature on-site or as a stand-alone unit.
