Product description
The Universa PRO and Universa MAX cooling thermostats are equipped with a bath cover and pump connections as standard. A drain valve on the front of the device behind the ventilation grid makes it easier to change the temperature control fluid safely.

Features

• Bath circulation thermostat with advanced electronics ensures precise control accuracy
• Focus on safety: The dedicated Tmax button provides convenient access to the essential overtemperature protection setting during commissioning
• Highly efficient refrigeration technology: Combination of speed-controlled inverter compressor and capacity control by means of electronic expansion valves and speed-controlled fans - improved energy efficiency and reduced operating costs; increased service life by avoiding frequent switch-on and switch-off cycles; dynamic approach to the set temperature; quieter operation
• Extensive functionality with programmer, safe mode, calibration options, controller self-adaptation and weekly planner for precise and flexible process control
• Wireless communication: Integrated WLAN enables effortless connection with PC, tablet and smartphone
• Future-proof thanks to modularity: LAUDA Universa with interchangeable control head and heating/cooling base allows flexible adaptation to current and future requirements
• Versatile pressure-suction pump: LAUDA Varioflex pump with eight selectable performance levels, adjustable flow rate distribution for internal/external circulation for optimal volume flow and pressure
• Environmentally friendly refrigerants: Use of natural refrigerants for sustainable and environmentally conscious cooling
• Intelligent remote control and monitoring: Integrated web server for remote control via LAUDA Command app or browser; secured by PKI and 2-factor authentication; connection to LAUDA.LIVE for cloud-based data analysis and remote maintenance
• Comprehensive safety functions: Effective over- and under-level protection; adjustable overtemperature protection with acoustic alarm; automatic system diagnostics at start-up with alarm and error message display; smart temperature control media management with automatic limit value adjustment
• Clear overview, intuitive operation: 5-inch colour TFT display shows temperature values with progression graph, menu navigation in six languages and operating status icons; controlled via cursor and soft keys
• Easily accessible front switch on the control head allows pump output adjustment during operation
• Adaptive bath edge ventilation (patent application): Prevents icing and condensation, stops water entering the bath, blocks vapors to protect electronics
• Maximum networking: Standard Ethernet, USB and interface for external Pt100 plus eleven optional interface modules
• Integrated Wi-Fi communication: The device may only be imported and used in certified countries and regions: United States of America, Canada, EU including the UK and Switzerland, and India
