Product description
The Universa U 1635 P is a bath circulation thermostat designed for precise temperature control in laboratory and industrial tempering applications. It features a bath cover, pump connections and a front drain valve for safe and easy fluid changes.

Features

• Bath circulation thermostat with advanced electronics for high control accuracy (temperature stability 0.02 ± K)
• Dedicated Tmax button for quick access to overtemperature protection during commissioning
• Energy-efficient refrigeration: capillary tube technology with speed-controlled inverter compressor and fan
• Integrated programmer, calibration options and weekly scheduler for flexible process control
• Wireless and network communication: integrated WLAN, Ethernet and USB; secure remote access via LAUDA Command app and LAUDA.LIVE cloud connectivity
• Modular design with interchangeable control head and heating/cooling base for future upgrades
• Efficient vario pump with six adjustable levels; flexible flow distribution for internal and external circulation
• Use of natural refrigerants for environmentally conscious cooling
• Comprehensive safety: float low-level protection, adjustable overtemperature protection with acoustic alarm, automatic limit-value adaption for tempering media
• 3.5" colour TFT display with progress graph, intuitive menu navigation and softkey control
• Adaptive bath-edge ventilation (patent pending) to prevent icing, condensation and vapor ingress
• Eleven optional interface modules for expanded communication needs; Wi‑Fi use restricted to certified countries/regions
