Process thermostat Integral IN 950 XTW

on castersdigitalelectronic

Overview
The Integral IN 950 XTW is a process thermostat combining integrated refrigeration and heating for dynamic temperature control of external circuits. Operation is via the device's colour TFT display or optionally via a touch operating unit with extended functions. The unit supports management of heat transfer fluids and includes ATEX gas-warning sensors for use in potentially explosive atmospheres.

Features

• Process thermostat with integrated cooling system for dynamic temperature control of external circuits
• Management of heat transfer liquids with stored fluid properties
• ATEX-certified gas-warning sensors with alarm, automatic shutdown and external status interface
• Self adapt function to determine control parameters
• LAUDA Variopump pressure pump with 8 selectable output levels or outflow pressure control
• Remote fault indication via floating contact
• Integrated web server for browser operation (PC, tablet, smartphone) with authentication and encryption
• Very small internal volume and large non-thermostated expansion vessel (cold fluid layer system)
• Use of natural refrigerants
• Colour TFT display showing actual and set values with graphical temperature profile
• Easy input via cursor and soft keys; dedicated Tmax key for overtemperature protection
• Quick-stop via black push-button and remote release contacts

• USB and Ethernet interfaces as standard; option for up to 2 additional interface modules (RS232/485, Profibus, analogue, contact, EtherCAT)
• Integrated adjustable bypass
• SmartCool digital cooling management with compressor on/off for energy saving
• Clear text menu navigation, six selectable languages (DE, EN, FR, ES, IT, RU)
• SelfCheck Assistant for system diagnosis
• Fully electronic continuous PID controller for internal and external control
• Adjustable low-level and over-temperature protection with acoustic alarm for flammable and non-flammable liquids
• Port for external Pt100; second external Pt100 feasible via interface module
• Programmer with 150 temperature/time segments separable into 5 programs
• Digital display of pump pressure
• Condenser cooling: Water
