From Freezing to Sweltering: Conlog’s All-Climate Commitment to Operability and Protection

Conlog’s Finnish roots, where temperatures can swing from -50°C in winter to 37.2°C in summer, have instilled a steadfast commitment to enable operability in the harshest environments.

Finland’s geographic location within the Arctic Circle subjects it to severe weather extremes, with winter temperatures plummeting to -45°C or even -50°C in the country’s eastern regions and Lapland. Yet, its summers can be surprisingly warm, even reaching a record high of 37.2°C in 2010.


This experience with such a wide range of temperatures directly informs Conlog’s product engineering. Ensuring functionality in frigid conditions is a core aspect of Conlog’s designs. Our containerised systems come outfitted with efficient and reliable climate control systems to keep the personnel comfortable and maintain operational conditions for equipment such as computers.


This resilience against cold extends beyond people and electronics; mechanically-operated components, such as the masts on Saab’s R-TWR deployable, digital control tower (for which Conlog supplies the containerised communication system), are designed to function even when laden with ice and snow.


In a dedicated cold weather chamber, we conduct exhaustive tests on subsystems and full products, ensuring their reliability at temperatures as low as -40°C.


Cold-weather operation, particularly in the -30°C to -40°C range, is crucial as materials such as rubber and plastics can become brittle. We source cold-weather performance components from external suppliers and subject them to rigorous destructive and non-destructive tests to guarantee their cold-weather performance.


We have even delivered container-based modules to Antarctica in support of Finland’s research activities and where temperature in wintertime can be from-40 to -70.



Ergonomics is another significant factor in low-temperature operation. Considering that personnel will likely be clad in bulky winter clothing and gloves, Conlog designs its products to be user-friendly under these conditions, with large buttons and switches that are easily operated even when wearing gloves.


Comms in a Cold Climate

Turning up the Heat


Conlog’s concern is not solely with cold weather. In today’s globalised world, militaries often operate far from their home climates, requiring equipment to perform in high temperatures and humid conditions.


We have supplied products to armed forces frequently deployed to hotter regions. Here, too, our stringent design methodologies prevail, with efficient cooling systems ensuring both equipment and personnel can withstand prolonged periods in hot environments.


All-Round Protection


Beyond weather-based adaptations, Conlog’s products are designed to shield occupants and systems from a variety of threats. Our solutions feature robust chemical, biological, radiological, and nuclear protection.


Likewise, ballistic protection ensures they can withstand kinetic fire. Given that many of the company’s products include electronic systems, Conlog ensures these are protected against the Electromagnetic Pulse (EMP).


The EMP is a short, but strong, burst of electromagnetic radiation accompanying a nuclear explosion. Several efforts are ongoing around the world to develop directed energy weapons which harness the EMP without needing a nuclear blast. The electromagnetic pulse can enter unshielded electronic equipment via power lines, telephone cables or antennas. Once inside the equipment, EMP voltages can wreck sensitive components.


Conlog employs EMP shielding technologies like Faraday Cages as standard in our products, preventing harmful pulses from damaging the equipment.



Finland’s unforgiving climate has been the perfect foundation for Conlog’s design philosophies. The company ensures its products can work in the world’s most extreme environments while protecting the equipment and personnel they house against a plethora of threats.
