Research projects by Cromocol

When built in 2016, Biotronen in Alnarp was the largest plant research facility in Sweden. The facility spans almost 1,100 square meters of research space and consists of 24 climatic chambers that allow researchers to recreate all climates: past, present, and future. The facility is open to researchers from all over the world and has become a hub for cutting-edge plant research.
The chambers can maintain temperatures ranging from -5°C to +45°C with controlled relative humidity (rH) up to 95%, and CO2 up to 3000 ppm. This enables researchers to simulate a wide range of climate conditions, including those in extreme environments, and study the plant response. 

The project was led by Cromocol with Elektrokyl Energiteknik providing installation and service support for the facility.

Linköping University is a renowned institution known for its innovative research and cutting-edge facilities. In early 2023, the university made headlines for its new project lead by Cromocol which aims to push the boundaries for indoor plant growth.

The project involves the installation of eight 25,000-litre Aralab climatic chambers that can reach temperatures as low as -20°C while the LED lights continue to operate. This allows researchers to recreate the climate of extreme environments like Antarctica and study the effect of cold temperatures on plant growth.

The chambers were built in collaboration with Cromocol, Aralab, and Elektrokyl Energiteknik, who provided expertise in refrigeration and climate control systems. The chambers are equipped with sensors monitoring temperature, humidity, Co², and light levels, allowing researchers to maintain precise conditions for their experiments.
