Variocool

Process thermostats

Variable process temperature control from -25 to 80 °C

The LAUDA Variocool process thermostats exist for efficient process temperature control in laboratories, miniplants and production environments. With cooling capacities from 1200 W up to 10 kW, these systems are suitable for the dissipation of process heat in applications requiring reliable temperature management within the moderate temperature range.

The Variocool series combines high performance with flexible configuration options, allowing the systems to be adapted to changing process requirements. Different pump options, interface modules and the possibility of external temperature control support customized integration into process environments.

Flexible configuration for process applications

You can equip the Variocool process thermostats with different pumps and expanded with interface modules to optimize their use in specific process setups.

External temperature control is possible through additional equipment, including a Pt100 module. Users can also add analog and digital communication interfaces to support integration into existing systems. A malfunction contact is included as standard equipment.

Efficient cooling and process monitoring

The Variocool series includes several functions that support reliable and efficient operation.

The adjustable bypass allows pressure limitation and supports operating control through pressure adjustment. The systems come with an electronic level indicator and low-level protection alarm for monitoring fluid levels.

The integrated SmartCool system provides energy-efficient digital cooling control, including automatic compressor management.

All models are available in air-cooled or water-cooled versions and come with steerable fixed castors for mobility. A built-in web server enables browser-based operation, while up to three additional interface modules can be installed through slots at the rear of the device.
