Temperature electronically controlled up to 600°C
The Leister Hot Air Tool Type 700 and the appropriate blowers are suitable for building into machines and are suitable for continuous use. The double-insulated hot air tool Leister Type 700 is small and space efficient. The Leister Type 700 hot air tool is available in many versions as described below. The Leister Type 700 hot air tool requires an external air supply to complete the process heating hot air system. The Leister Type 700 hot air tool is available in single-phase 120V or 208-230V, up to 800 watts.
The standard Leister Type 700 comes with a potentiometer for fine-tuning the temperature electronically from ambient to 600°C. The Leister Type 700 hot air tool has an air regulator valve built in so the air volume can be fine-tuned, as well as an overheating protection system to protect the heater against total failure. If required, the potentiometer can be sited away from the hot air tool, max. lead length 5m.
For precise temperature control with a digital display of set and actual temperatures from the heat gun, the Leister Type 700 hot air tool can also be supplied with a control cable from the Leister heat gun to the Leister Interface so that this unit can be controlled from a PLC or external temperature controller. A thermocouple can be placed in the hot air stream to provide feedback to the PLC or temperature controller. As another alternative, Malcom can supply the Leister Type 700 hot air tool with a PID digital temperature controller housed in a compact enclosure that has a built-in female mini plug port for a K Type thermocouple and two alarm output ports, pre-wired with mains power cord, thereby making it turnkey. The auto-tune function in the controller will have to be activated once the heater is mounted in place in order to self-tune the hot air system for the process heat application.
The Leister Type 700 hot air tool can be supplied without any electronics, heating element protection or airflow controls; however it will have built-in overheating protection. Malcom offers external SCR power controllers, solid state contactors, and a full line of 1/16 DIN digital process controllers.
The Leister Type 700 heat gun requires an air source to complete the hot air system. The Leister Type 700 hot air tool can be used with compressed air or blown air from the full line of Leister regenerative and side channel blowers, as well as airflow valves and on/off valves. Malcom also offers a full line of high pressure regenerative blowers, rotary vanes, diaphragms, and linear pumps that can be used as well.
Malcom offers over 100 standard stainless nozzle attachments to direct hot air where you want it. The air outlet of the Type 700 heaters, without nozzle attachment, is 22mm diameter, the size of the heater is 34 x 124 mm.
The Leister 700 is available with or without electronics. The 700 heater can be configured to be run through an external control system such as a SCR power controller, a PLC or a PID digital controller. Click here for information about Malcom Company's control systems.
