Thermostats
Heating bridge and clear view thermostats with temperature control from 30 to 230°C for professional use in research, application technology and production.
For more than ten successful years now, the LAUDA Proline name has stood for uncompromisingly reliable thermostating, intuitive operation and high flexibility in the research, application technology and production areas.
LAUDA Proline thermostats are our solution for high performance and reliable temperature regulation. With their broad temperature range they fulfill high requirements. LAUDA Proline thermostats are available in two versions: in the basic version with the Master control head, and as a Command version with a removable control unit for enhanced ease of operation.
Master version devices can be retrofitted with the Command remote control, which are simply connected to the control head. The thermostat automatically recognises and controls all newly installed modules.
Application examples
- Temperature control for chemical synthesis
- Tests on electronic components at different temperatures
- Temperature control of measuring structures in process technology
- Heating and cooling of glass reactors

The Proline Advantages
Removable remote control unit for easy and intuitive operation
Extendable telescopic rods for mounting on 310 up to 550 mm wide baths
Master or Command version – the right solution for every application
Simple retrofitting from Master to Command version – subsequent extension or adaptation to changing application requirements
Graphical user guidance – easy and intuitive operation
Adaptive control on cooling thermostats – saves time-consuming calculation of control parameters
Patented SmartCool system – up to 75 percent energy saving with digital cooling management
PowerAdapt system for adjustment of the power consumption – use of the maximum available output from the power supply system
Two insert ports can be combined with five different interface modules – high level of flexibility for the user allowing for broad range of system integration
Easy distribution of the pump flow by means of bypass valve – simultaneous connection of two external applications
Pump connections on the side and rear – flexible connection of external applications from different sides
High-performance pressure-suction-pump (Varioflex pump) with eight pump levels – suitable for internal and external applications; adaptation of the pump power to the respective application and bath size
Up to 3.5 kW (230 V) heating power – even on all cooling thermostats via SmartCool system – rapid heating achieved
Proline Control Heads
Proline Master control head
The Proline Master devices are designed with high thermostating accuracy and reliability for all applications from -90 up to 300 °C where operating parameters are not changed or modified frequently. They have all the basic features and safety functions required for professional thermostating during continuous use. A modular structure and bus technology have created an instrument capable of extending its function and performance as the application requires.
- Easy-to-read green LED display
- Convenient setting of set-temperature and Varioflex pump via three operation buttons
- Indicator lights for heating, cooling, external control and alarm
- Resolution of indication 0.01 C, setting resolution selectable 0.1 or 0.01 °C
- Selectable operating temperature range and additional button for overtemperature protection
- External temperature control via Pt 100
- Optical and audible alarm function
- Simple temperature probe calibration
- Integrated mains network safety device
- Start mode control (automatic or manual)
- Two slots for LiBus modules
- LAUDA Wintherm Plus control software via RS 232/485 interface (optional)
Proline Command control head
The Command control heads are the top models of the LAUDA Proline. The highly-efficient programmer fulfills all the requirements of complex thermostating processes D with real-time function. It offers the utmost in user-friendliness and optimum functionality, e.g. for an industrial testing lab. The simple menu-driven operation and the easy editing of test programs allow for quickly changing thermostating tasks. The Command console is removable and can easily be used as a remote control (with cable). Comprehensive basic equipment as with the Proline Master range.
Proline Clear-view thermostats
LAUDA Proline clear-view thermostats for the direct observation of the samples: the PVL models come equipped with five layers of insulating glass and are suitable for low temperatures down to -60 °C. This makes them ideal for the use with the fully-automatic LAUDA PVS viscosity measuring system. The two-chamber principle in the measuring area ensures a constant level, irrespective of the loading and the temperature. The connection of a through-flow cooler or Proline RP 890 enables low temperature measurements down to -40 °C/-60 °C.
Proline Bridge thermostats
LAUDA Proline bridge thermostats are available in two versions with different pump models and immersion depths. The PB models have a pressure/suction pump and require a bath depth of 200 mm, while the PBD models have a more powerful pressure pump (D) and thermostat baths with a depth from 320 mm. In addition, both series of models differ in the selected control head: Master or Command (C). Through variably extendable telescopic rods, all models can be attached without problem to baths with a width of 310 mm up to 550 mm.
