Process thermostats with integrated cooling system for dynamic temperature control within external circuits.

• Coloured TFT display for simultaneous indication of actual and set values and graphic illustration of the temperature profile
• Clear text menu navigation, six selectable languages DE, EN, FR, ES, IT and RU
• Management of heat transfer liquids with stored properties
• Easy input via cursor and soft keys. Additional Tmax key for overtemperature protection
• SelfCheck Assistant for system diagnosis
• Fully electronic continuous controller with PID action for internal and external control
• Self adapt function for determination of control parameters
• Programmer with 150 temperature/time segments that can be separated into 5 programs with digital display of pump pressure

The Thermostat comes with a PowerAdapt system enabling usage of the maximum possible amount of heat permitted by the power supply system; with a low-level and adjustable over-temperature protection with acoustic alarm for use with flammable and non-flammable liquids. An integrated powerful LAUDA Variopump (pressure pump) with 8 selectable output levels for control of outflow pressure.

USB and Ethernet interface equipped as standard, as well as a port for external PT100, second external PT100 feasible via interface module. Option for upgrading up to 2 additional interfaces (RS 232/485, Profibus, analogue, contact or EtherCAT module) and an integrated web server for browser based operation in local area networks via PC, tablet or smart phone, secure data transfer due to authentication procedure and encryption.

Remote fault indication through floating contact and an integrated and adjustable bypass. Not only does it incorporate a SmartCool system for energy-saving, digital - cooling management, including compressor on-off control, but more importantly a very small internal volume and big non-thermostated expansion vessel (cold fluid layer system) and Condenser cooling Water. Units utilise traditional refrigerants (HFCs) in accordance with European legislation to control F-gases (EU) 517/2014. Max. pumping pressure: 3,1 bar; flow rate: 65 L/min for all models except IN 4XTW/IN 8XTW: 3,1 bar; flow rate: 60 L/min, IN 1850XTN: 6 bar, flow rate: 120 L/min.
