Lumikko WBlock is a wall-mounted enclosure cooling unit designed for mobile containers, equipment rooms and other critical spaces where reliable temperature control is essential. Built for demanding defence, industrial and mobile applications, WBlock keeps sensitive systems and equipment operating reliably in harsh environments.

The unit provides efficient cooling and optional heating for year-round use, maintaining stable conditions in ambient temperatures from -40 °C to +50 °C. Its inverter-controlled compressor adjusts performance according to demand, helping reduce energy consumption, balance load and extend service life.

WBlock is easy to install, commission and operate. The wall-mounted design saves space, while the thermostat-based control automatically maintains the selected target temperature. A freely positionable control panel and external temperature sensor enable accurate monitoring exactly where it is needed.

With a modular structure and multiple configuration options, WBlock can be adapted to different project requirements. Available options include 24 VDC and 230 VAC versions, heating alternatives, diesel heater integration and customized control solutions.

Compact, robust and configurable, Lumikko WBlock offers dependable thermal management for containers, mobile units, technical rooms and equipment exposed to demanding operating conditions.
