Main features



Single compressor technology
Single compressor technology with a simple structure that ensures easy maintenance, lower heat dissipation, low energy consumption, and noise reduction.

Noise reduction
Thanks to our newly developed noise reduction technology, we are able to reduce the noise level drastically, for a more pleasant work environment.

Filterless construction
Filterless construction prevents dust from blocking the airflow and reduces the unit’s ability to dissipate heat effectively, which minimizes maintenance procedures.

100 % HCFC & CFC free
Arctiko can proudly confirm that we are 100% HCFC & CFC free, and we aim to use the most environmentally friendly solutions in our products.

Sub lids
Insulated sub lids are added to minimize cold loss during door openings and keep your samples safely stored at all times.

Low energy consumption
Our products aim to have as low a CO2 footprint as possible, by choosing energy-efficient components of high quality throughout the development and design process.
