Lauda – Universa Cooling Thermostats

Energy-efficient cooling systems with inverter technology

Universa cooling thermostats are available in three performance classes. The economical entry-level variant Universa ECO offers 200 W cooling capacity with a working temperature range of -30 to 100 °C (available from Q4/2025). Universa PRO for professional temperature control covers a working temperature range of -45 to 200 °C with a cooling capacity of 0.2 to 0.8 kW. As the high-end solution and most powerful variant, Universa MAX offers up to 1.6 kW cooling capacity with a working temperature range of -90 to 300 °C. For the control heads, bath bases with a filling volume of 4 to 40 liters are available.

The chillers are available as single-stage and cascade versions. Thanks to the interchangeable control head and the combinable heating/cooling base, LAUDA Universa devices can be flexibly adapted to changing requirements and areas of application. The adaptive bath edge ventilation (patented) of LAUDA Universa cooling thermostats prevents icing and condensation, stops water ingress and blocks vapors to protect the electronics. This innovation significantly increases the operational safety and service life of the appliances.

All Universa devices are equipped with USB, Ethernet and Wi-Fi interfaces as standard. The most powerful models use speed-controlled inverter compressors with electronic expansion valves and adjustable fans. This technology increases energy efficiency by up to 78 percent while significantly reducing operating costs. At the same time, it ensures a longer service life, dynamic start-up of the set temperature and quieter operation.

Key Features

• Patented, adaptive bath edge ventilation prevents icing and condensation
• Adjustment of the flow distribution for internal/external circulation from the front, even during operation (PRO and MAX variants)
• Natural refrigerant and minimum charge of less than 100 g
• Integrated web server for wireless remote control and IOT connection for cloud-based data analysis and remote maintenance
