Refrigerated thermostatic bath Integral IN 950 XTW

automaticheatedconstant temperature

Overview
Operate the Integral IN 950 XTW process thermostat via its colour TFT display or, optionally, via an intuitive touch operating unit. The device combines an integrated cooling system, configurable pump control and extensive safety and communication options for industrial temperature control tasks.

Key features

• Process thermostat with integrated cooling system for dynamic temperature control of external circuits
• Management of heat transfer fluids with stored media properties
• ATEX-certified gas-warning sensors with alarm and automatic shutdown and external status interface
• Self-adapt function to determine optimal control parameters
• LAUDA Variopump with 8 selectable output levels or outflow-pressure control
• Remote fault indication via floating contact
• Integrated web server for browser-based operation (PC, tablet, smartphone) with authentication and encryption
• Very small internal volume and large non-thermostated expansion vessel (cold-fluid layer system)
• Uses natural refrigerants
• Colour TFT indicates actual and set values plus graphical temperature profile
• Easy input via cursor and soft keys; additional Tmax key for overtemperature protection
• Quick-stop via black push-button and remote-release contacts
• PowerAdapt system to use the maximum permitted heating power from the supply
• USB and Ethernet interfaces standard; optional upgrade with up to 2 additional interfaces (RS232/485, Profibus, analogue, contact, EtherCAT)
• Integrated adjustable bypass and SmartCool energy-saving digital cooling management including compressor on/off control
• Clear-text menu in six languages (DE, EN, FR, ES, IT, RU) and SelfCheck assistant for diagnostics
• Fully electronic continuous PID controller for internal and external control
• Low-level and adjustable over-temperature protection with acoustic alarm for flammable and non-flammable liquids
• Port for external Pt100 integrated; second external Pt100 feasible via interface module
• Programmer with 150 temperature/time segments, separable into 5 programs
• Digital pump pressure display; condenser cooling: water
