Laboratory thermostat Integral IN 2050 PW

floor-standingdigitalelectronic

Product overview
Integral IN 2050 PW is a process thermostat designed for pressurised operation with integrated water-cooled refrigeration. It draws the heat-transfer medium into the unit by compressed air filling (negative pressure -0.2 bar) and supports non-flammable tempering fluids. The device uses a modular interface concept for flexible integration into industrial processes.

Key features

• Process thermostat for pressurised operation with integrated cooling for dynamic temperature control in external circuits
• Clear-text menu navigation, six selectable languages: DE, EN, FR, ES, IT, RU
• SelfCheck Assistant for system diagnosis and status monitoring
• PowerAdapt for optimised use of available heater power without overloading the supply
• USB and Ethernet interfaces standard; up to 2 optional interface modules (RS232/485, Profibus, analogue, contact, EtherCAT)
• Integrated adjustable bypass and digital pump-pressure display
• Filling by compressed air or drum pump (negative pressure -0.2 bar)
• Uses conventional refrigerants (HFC) compliant with Regulation (EU) 573/2024
