One-button operation runs the whole heating and cooling cycle, so tool changes stay quick and simple.

Works with all MST tool holders, with an excellent performance-to-price ratio and a short payback period.

Auto mode: turn the selector to “AUTO” and press “NO” — the unit completes heating and cooling on its own. The cycle is timed by a relay and can be adjusted freely.

Manual mode: with the selector on “MANUAL”, heating and cooling are operator controlled. “OFF” shuts the unit down, “HOT” heats the holder and “COOL” cools it.

Installation and Wiring

Plug the power cord into a properly installed socket.
Connect the shop air supply to the cabinet inlet with an 8 mm air line.

Operating Instructions

Once installation and wiring have been checked, switch on the AC supply.
Select the operating mode: manual or auto.
Set the tool holder in the loading position.
Set the heating and cooling times. Heating is typically set to 2 min 30 s; cooling time can be adjusted to suit the job.
Start the cycle.
In auto mode the heater pauses for ten seconds once the heating time is reached. Insert the tool within those ten seconds, after which cooling starts automatically.
In manual mode, heating and cooling do not stop or switch over on their own — the operator has to stop and change over each step.
In auto mode the manual switch has no effect.

Outdoors

Use an AC supply within the rated range: 220 V ±10 %, 50 Hz ±5 %.
