POL-EKO laboratory freezers
POL-EKO – Laboratory freezers
POL-EKO laboratory freezers provide a reliable and stable solution for the long-term storage of biological, chemical and industrial samples. The range is divided into two main technology groups: laboratory freezers with natural air convection and forced-air circulation, enabling the ideal solution to be selected for every application.
Laboratory freezers with natural convection
Laboratory freezers with natural convection maintain a stable temperature without a fan. This solution is particularly beneficial for samples sensitive to air movement or desiccation.
Benefits:
- Quiet operation, minimal vibration
- Uniform, natural heat distribution
- Ideal for long-term sample storage
- Low maintenance requirements
Laboratory freezers with fan-assisted air circulation
These laboratory freezers use a fan-assisted system that ensures rapid, uniform temperature distribution throughout the chamber. This is particularly important when the door is opened frequently or when storing larger quantities of samples.
Benefits:
- Rapid temperature recovery after door opening
- Outstanding temperature uniformity
- Stable operation even under heavy loads and intensive use
- Ideal for controlled environments
