Integral P

The LAUDA Integral P process thermostats are ideal for professional temperature control in realistic test processes and external applications. Operating according to the flow principle with a pressure overlay of up to 4 bar, the systems allow non-flammable water/glycol mixtures to be used in a temperature range from -40 to 140 °C.

The electronically controlled, magnetically coupled pump enables the flow rate to be adjusted to suit different applications. The Integral P series also supports the LAUDA.LIVE platform for remote monitoring, remote maintenance and additional digital functions.

Performance and operating principle

The Integral P process thermostats combine dynamic heating and cooling with pressurized operation to support demanding temperature control applications.

Key benefits include:

• Fast heating and cooling cycles
• Temperature control with non-flammable water/glycol mixtures from -40 to 140 °C
• Demand-based flow rates for different applications
• Reliable performance, even with high pressure drops and low flow rates

The systems come with a compressed air supply that draws the heat transfer liquid into the thermostat using a negative pressure of -0.2 bar. Like other new-generation LAUDA Integral thermostats, the Integral P series features a modular interface concept that allows flexible integration into user processes.

Temperature control and pump technology

The Integral P process thermostats feature a fully electronic PID controller for both internal and external temperature control.

A powerful LAUDA Variopump (pressure pump) provides eight selectable output levels or pressure-controlled operation. The systems also include:

• Integrated and adjustable bypass
• Digital display of pump pressure
• Self-adapt function for determining control parameters
• SelfCheck Assistant for system diagnostics
• PowerAdapt system for optimized use of the available electrical power supply
• SmartCool system for energy-saving digital cooling management with compressor on/off control

The thermostats have a very small internal volume combined with a large, non-thermostated expansion vessel based on the cold fluid layer system.

User interface and connectivity

The system uses a colour TFT display for operation and simultaneously displays actual and set values together with a graphical temperature profile.

The interface offers:

• Cursor and soft-key operation
• Additional Tmax key for overtemperature protection
• Clear-text menu navigation
• Six selectable languages: German, English, French, Spanish, Italian and Russian

USB and Ethernet interfaces come as standard. Up to two additional communication interfaces can be installed, including:

• RS 232/485
• Profibus
• Analogue interface
• Contact module
• EtherCAT module

An integrated web server enables browser-based operation from a PC, tablet or smartphone within a local network. Secure data transfer is provided through authentication and encryption.

Safety and process functions

The Integral P series includes several functions designed to support reliable operation and process safety:

• Low-level protection
• Adjustable overtemperature protection with acoustic alarm
• Integrated connection for an external Pt100 sensor, with support for a second external Pt100 through an interface module
• Remote fault indication via a floating contact
• Management of heat transfer liquids with stored properties
• Filling using compressed air or a drum pump
• Suitable for use with non-flammable liquids

An integrated programmer supports up to 150 temperature/time segments, which can be divided into five separate programs.

Refrigeration

The Integral P process thermostats incorporate an integrated cooling system for dynamic temperature control in external circuits. Condenser cooling is water-based. The systems use traditional HFC refrigerants in accordance with European F-gas legislation (EU) 573/2024.
