The control panel can be positioned in the desired location, and the external temperature sensor ensures accurate measurement. The system operates autonomously according to the defined temperature setpoint.
Reliable thermal management for mission-critical environments – all year round
Lumikko Wblock is a wall-mounted cooling and temperature control unit designed for enclosures, containerized systems, mobile units and demanding industrial applications. It ensures stable operating conditions for critical equipment even in extreme environments.
Originally developed to meet the requirements of the defence industry and other security-critical applications, Wblock combines robust construction, inverter-driven efficiency and flexible configuration.
Why Choose Wblock?
- Engineered for Extreme Conditions:Designed to operate in ambient temperatures from -40 °C to +50 °C. Suitable for arctic climates as well as hot industrial environments.
- Energy-Efficient Inverter Technology: The compressor features integrated inverter control, enabling capacity adjustment according to actual cooling demand. This improves part-load efficiency, reduces cycling and minimizes mechanical stress.
- Simple Operation: Set the target temperature and the system automatically maintains stable internal conditions.
- Flexible Control and Measurement: The control panel can be freely positioned inside the enclosure. An external temperature sensor enables accurate measurement exactly where it matters.
- Integrated Fresh Air Function: Built-in fresh air functionality eliminates the need for a separate supply air fan.
- Modular and Configurable:Wblock can be tailored to meet specific project requirements, including voltage and heating options.
