This system will produce a very high quality vacuum bag heatseal in a high vacuum.
With this design the thermal control loop is closed: ACTUAL temperature = SET temperature.
Even minute thermal loads on the heatsealing band are detected and corrected quickly and precisely. Abbess uses Ropex RS440 temperature controllers, to control the temperature of heating elements (heatsealing bands, beaded bands, cutting wires, heatsealing blades, solder elements etc.), as required in a variety of heatsealing processes.
This Vacuum Chamber design is a rugged industrial bench top unit for use in production or testing.
Some of our customers find this to be a practical size for use in vacuum work. With optional thermal shelves, these thermal vacuum chambers can be very effective in product handling, drying and sealing without exposure to air.
This chamber is also used in many other industries where vacuum work is required.
Standard Chambers are constructed of welded 304 Stainless alloy with interior standard dimensions of 14, 18, 24, and 36 inch cubes. Custom dimensions are available.
The door seal is a (customer replaceable) 3/16″ thick O-ring seal to withstand repeated closings. Two draw latches close the front hinged door.
All chambers are vacuum tested to 29.92 inch(Hg) or better (10-4 torr optional) and should maintain this for its life dependent on seal condition and customer use.

|Included Features:||This RESISTRON temperature controller is an integral part of the “series 400”, the outstanding feature of which is its microprocessor technology. All RESISTRON temperature controllers are used to control the temperature of heating elements (heatsealing bands, beaded bands, cutting wires, heatsealing blades, solder elements etc.), as required in a variety of heatsealing processes.
Principle of operation
The resistance of the heatsealing band, which is temperature-sensitive, is monitored 50x per second (60x at 60Hz) by measuring the current and voltage. The temperature calculated with the help of these measurements is displayed and compared with the set point. The primary voltage of the impulse transformer is adjusted by phase-angle control if the measured values deviate from the set point. The resulting change in the current through the heatsealing band leads to a change in the band temperature and thus also its resistance. This change is measured and evaluated by the RESISTRON temperature controller. The control loop is closed: ACTUAL temperature = SET temperature. Even minute thermal loads on the heatsealing band are detected and can be corrected quickly and precisely. The thermoelectric control loop which is formed has a highly dynamic response because purely electrical variables are measured at a high sampling rate. A high secondary current can be controlled with only minimal power loss because power is controlled on the primary

Description of the Controller
The microprocessor technology endows the RESISTRON temperature controller RES-440 with previously unattainable capabilities:
• Very simple operation thanks to AUTOCAL, the automatic zero calibration function.
A time control (timer) function integrated in the controller enables the complete heatsealing process to be controlled on simple machines, such as table heatsealing tools. A configurable relay output can be used to drive motors, energize magnets etc.
