LAUDA Integral IN 750 XT

Process Thermostat | -50 – 220°C, 7kW @ 20°C Cooling

The LAUDA Integral IN 750 XT is a process thermostat with integrated cooling that provides dynamic temperature control from –50 °C to 220 °C with ±0.05 K stability for external circuits. It delivers up to 8 kW heating power, 7 kW cooling capacity, and 65 L/min pump flow with 3.1 bar pressure, controlled by a PID system with programmable temperature profiles and self‑adapt tuning. The unit includes USB and Ethernet interfaces, an integrated web server, SmartCool energy management, and safety systems such as overtemperature protection, ATEX gas sensors, and quick‑stop shutdown for controlled operation in industrial environments.
