Proline Heating thermostats

Proline Heating thermostats with Master control head up to 19 liters

The heating thermostats of the LAUDA Proline with Master control head do not only shine because of their compact construction. The high heater power of 3.5 kW (230 V), two interfaces for various modules, a cooling coil fitted as a standard feature, and an integrated external control D these features make them particularly useful for users who require flexible thermostating operations while only rarely needing to adjust the settings

Proline Heating thermostats with Master control head up to 53 liters

The LAUDA Proline P 26, P 40 and P 50 heating thermostats are distinguished by particularly large-volume baths. All the below models are equipped with a Varioflex pump and cover the temperature range from 30 up to 300 °C. These stainless steel baths are ideally suited to direct thermostating inside the bath. The P 40 is particularly suitable for thermostating applications needing a large submersion depth. The P 26 and P 50 models with their wide baths, allow long or bulky test pieces to be placed in the bath or even enable a number of test pieces to be positioned alongside each other, for simultaneous testing. A circulation chamber on the P 40 and P 50 ensures good mixing in the bath and thus guarantees good temperature homogeneity, despite the large bath vessel.

Proline Heating thermostats with Command control head up to 19 liters

The Proline heating thermostats with Command control head (C) impress through an expanded scope of functions. Alongside a graphic LCD display, which enables current values to be displayed up to 0.001 °C resolution, an easily editable and convenient programmer with storage possibilities is available. The standard RS 232/485 interface enables communication with a computer. Work flexibly with Command: The Command remote control can be quickly and easily detached from the thermostat.

Proline Heating thermostats with Command control head up to 53 liters

In order to enhance ease of use even further, P 26 °C, P 40 °C and P 50 °C heating thermostats with large baths are also available with the Command control head which allows complex thermostating functions, particularly those with internal thermostating processes, to be easily mastered with the aid of an intuitive operation guidance system and the ability to edit programs rapidly. A circulation chamber on the P 40 and P 50 ensures good mixing in the bath and thus guarantees good temperature homogeneity, despite the large bath vessel.

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.

Proline Cooling thermostats

Proline Cooling thermostats with Master control head up to 8 liters

The Proline RP 845, RP 855, RP 870 and RP 890 cooling thermostats stand out above all for their compact dimensions and small footprint. With a cooling capacity of 1.6 kW at 20 °C, the RP 855 has a particularly high-performance design. The RP 890 low-temperature device enables you to reach temperatures down to -90 °C. The standard integrated bath bridge heating prevents ice build up as a result of condensation and humidity on all Proline cooling thermostats with a temperature range down to -90 °C.

Proline Cooling thermostats with Master control head up to 35 liters

The Proline RP 1290, RP 1840, RP 1845 and RP 3530 cooling thermostats differ in terms of bath volume, achievable cooling capacity, and working temperature range. With bath capacities up to 35 liters, the RP 3530 provides a particularly large bath volume and the RP 1845 provides a particularly high cooling capacity of 1.6 kW.

Proline Cooling thermostats with Command control head up to 8 liters

The SmartCool system D an energy-saving, digital cooling management system D ensures that every temperature is run with the correct cooling capacity. It increases or reduces the cooling according to application requirements. The advantages are particularly effective for programmer operation and temperature ramping. The Proline cooling thermostats with the Command control head (C) have a convincing extended range of functions. At 20 °C, RP 855 C has a particularly high cooling capacity of 1.6 kW. RP 890 C and RP 1290 C are designed for especially low temperatures. They differ in terms of bath volume and have bath bridge heating as a standard feature.

Proline Cooling thermostats with Command control head up to 35 liters

Thanks to their various capacity ranges and filling volumes, the Proline cooling thermostats which make up the Command range skilfully adapt to your requirements. The RP 1845 C works at a temperature range between -50 and 200 °C and, at 20 °C, has a cooling capacity of 1.6 kW. The RP 3530 C has a particularly large bath for internal sample thermostating.
