Laboratory Refrigerators
Laboratory refrigerators can maintain a temperature from 0°C up to 15°C
The CHL laboratory refrigerator is a specialized device for storing temperature-sensitive samples. The laboratory refrigerator has a cooling system that allows samples to be stored below ambient temperature. Such storage guarantees the physical and chemical stability of the sample.
Laboratory refrigerators/fridges are equipped with highly advanced microprocessor temperature controller Smart or Smart PRO, which maintains the set temperature with high stability and uniformity. A main advantage of the controller is a large and colourful display and intuitive operation even when wearing latex or nitrile gloves. In laboratory refrigerators/fridges, temperature is the priority, so the compressor is turned on when necessary. Comparatively in refrigerators the compressor turns on with a constant interval, regardless of the temperature in the compartment. POL-EKO laboratory refrigerators have forced air circulation, which provides temperature uniformity inside the device. Two-component polyurethane foam provides perfect insulation of the refrigerator chamber and refrigerants used by POL-EKO are ecological.
The CHL laboratory refrigerators are specialized equipment used, among others, in accredited laboratories for storing temperature-sensitive samples.

Laboratory Freezers
Laboratory freezers can freeze and store frozen samples.
POL-EKO fridge-freezers are two-chamber devices – one chamber is a refrigerator, the other is a freezer. Bearing in mind device parameters and their functionality, there are three product categories: laboratory refrigerators, laboratory freezers and ultra-low freezers. Laboratory refrigerators are equipped with a cooling system – they keep the temperature lower than the ambient temperature, however their temperature range doesn’t reach negative values. Usually it is 0-10 or 0-15°C. In the case of laboratory freezers, the temperature inside the chamber may reach -25/-40°C. The temperature goes even lower in ultra-low freezers – down to even -86°C.
Laboratory Freezers with natural air convection
The ZLN 85 freezer and the three ZLN-T freezer models with available capacities 130, 210 i 310 litres are natural-air appliances. The freezers are available with Smart and Smart PRO controllers, and their compartments can be made in C (comfort), CS (comfort/S), P (premium) and PS (transform/S) versions.

Laboratory Freezers with forced air convection
The ZLW-T freezers are devices with forced air circulation. Models are available with capacities of 210 and 310 litres. By using a fan, the stability and uniformity of the temperature in the chamber is greatly improved, and the cartridge is cooled faster. The effect of faster cooling of the load is particularly beneficial in situations where the chamber must be opened frequently.

Ultra-Low Freezers
"As Smart As Your Smartphone" ultra-low freezers ZLN-UT
Ultra-low-temperature freezers (ZLN-UT) are devices that allow deep freezing and long-term storage of biotechnological samples and other materials in the temperature range from -86°C to -50°C. Depending on the application, you can choose the COMFORT model (interior made of stainless steel DIN 1. 4016) or PREMIUM (interior of acid-resistant stainless steel DIN 1. 4301).
ZLN-UT Freezer with VIP Panels
Ultra-Low Freezers with polyurethane foam insulation are available in 3 chamber sizes 259 and 482 litres. Due to the maintenance of low temperatures, for the ZLN-UT devices as an option we offer a set for connecting a CO2 cylinder, which will be an emergency cooling of the batch in case of failure due to e. g. power outage. The CO2 back-up system is a solution that protects the load from thawing too quickly.
