Fonctionnement

Closed test chamber with PID-controlled nickel-chromium heating elements (1.5 kW x2, L=350 mm) executed via 60 A solid-state relay (Gute). Circulation fan (90 W) distributes hot air through SUS304 stainless steel air duct. Platinum Pt100 sensor measures dry-bulb temperature; Canadian Reals 560 controller maintains setpoint. Manual damper switches between circulation and air exchange modes. Operator-set timer: 0-99h59min or 0-999h selectable.
