LAUDA Universa PRO cooling thermostat

LAUDA Universa PRO refrigerated thermostat

This high-performance device is particularly suitable for laboratories, pilot plants and industrial processes that require precise temperature control in the -45 to +200 °C range. Unlike many conventional temperature control systems, it offers an intelligent, modular design and optional integrated Wi-Fi capability for seamless communication and remote monitoring. This reduces both energy consumption and the effort required for maintenance and operation and sets new standards in terms of flexibility and future-proofing.

Efficient temperature control for demanding applications

The series fulfils the requirements of DIN 12876 and works with advanced electronics that enable precise temperature consistency of ±0.02 K. A key feature is the speed-controlled refrigeration system with inverter compressor and electronically controlled fan. This reduces energy consumption and noise levels, which is particularly advantageous in noise-sensitive environments such as research or quality assurance laboratories.

An integrated Tmax button ensures that the overtemperature protection can be conveniently set. In addition, the adaptive bath edge ventilation ensures that condensation and icing are minimised. The operating concept with colour 3.5-inch TFT display and cursor softkeys is intuitive and multilingual to ensure efficient navigation through all appliance data and menu functions.

Important technical features at a glance

- Temperature ranges from -20 to -45 °C (depending on model) up to +200 °C
- Modular combination of control head and heat transfer section
- Speed-controlled inverter compressor for efficient cooling
- Six selectable pump stages (vario pump) for internal and external circulation
- Environmentally friendly refrigerants and sustainable cooling technology
- Ethernet and USB interfaces as standard, various optional expansion modules
- Robust safety concept with adjustable overtemperature protection and low level protection

A flow rate of up to 22 l/min can be realised for all versions, and the maximum delivery pressure is 0.6 bar. The bath opening and usable volume vary depending on the model (e.g. U 420 P with 1.8-4.0 litres or U 1245 P with 8.5-13.0 litres). Thanks to the robust design and optimised cooling system, use at ambient temperatures of up to 40 °C is guaranteed. For maximum flexibility, it is possible to connect external temperature control circuits (M16 x 1).

Devices such as the U 635 P or U 1635 P reach even lower temperatures down to -35 °C and also offer cooling capacities of up to 0.5 kW in the near range of 0 to 20 °C. With thermal oils, they can also be ramped up to high temperatures of up to 200 °C without any loss of control accuracy.Certifications and standards

The entire series is designed in accordance with DIN 12876 and therefore guarantees a high level of safety and reliability for the temperature control of liquids in laboratory and industrial environments. The extended safety concept includes:
- Overtemperature protection with acoustic alarm
- Low level protection thanks to float technology
- Smart limit value adjustment depending on the medium

This design means that the system can be used for most common laboratory media, including ethanol and suitable heat transfer oils

Application examples

1. Temperature control for chemical reactions: Thanks to the high control accuracy, complex syntheses can be carried out at a stable temperature, especially with ethanol or thermal oil as the heat transfer medium.
2. Material tests and viscosity measurements: Reliable temperature control is essential for quality tests in the plastics or metal industry.
3. Biotechnological processes in the research environment: The system can be adapted to sensitive sample environments with different pump stages.
4. Pharmaceutical analysis: Constant conditions are crucial when storing or testing temperature-sensitive substances such as enzymes or proteins.

FAQs

How easy is it to switch between internal and external circulation?

It is very straightforward, as the pump output can be adjusted using the front switch and menu navigation. This allows the user to quickly switch between different circulation requirements.

Do I need special hoses for external connections?

Due to the M16 x 1 connection thread, we recommend using suitable high-performance hoses that are designed for the desired temperature and the respective medium.

Can the temperature control unit also be run in continuous operation?

Yes, the appliance is designed for continuous use. The robust design and speed-controlled compressor enable stable, continuous operation even with demanding processes.

What about compliance with safety regulations?

The entire system fulfils the relevant standards and regulations (e.g. DIN 12876). The protective mechanisms, such as the adjustable overtemperature protection and the acoustic warning signal, also ensure safe operation.

Which media are typically used

Typical media are ethanol and thermal oils, depending on the temperature range. For low temperatures down to -45 °C, ethanol is the preferred choice, while for higher temperatures above +100 °C, thermal oils are an option.

Conclusion

Thanks to its modern electronics, integrated safety functions and modular design, the refrigeration appliance offers maximum performance, efficiency and ease of use. Whether in the research sector, in quality assurance laboratories or in the process engineering industry: the reliable temperature control, flexible pump control and extensive range of interfaces allow uncomplicated integration into almost any laboratory or production environment. This makes it a future-proof system for a wide range of applications and increasing demands on temperature accuracy.
