Refrigerators and freezers · POL-EKO
Stable temperature, proven cold chain.
From pharmaceutical refrigerators for vaccines and medicines to laboratory freezers and ultra-low freezers down to −86 °C, POL-EKO covers the full temperature range for samples and temperature-sensitive products. APICAL helps you match the choice to application, capacity and validation requirements.
Cold chain, mapping and qualification as part of validation
Cooling equipment for laboratories and pharmaciesTemperature is not a setting, it is a quality requirement. The right unit, monitoring and documented validation together protect samples, medicines and vaccines.
APICAL × POL-EKOAn overview of device families, capacities and temperature ranges.
Temperature ranges
Eight groups, one goal: stable temperature.
POL-EKO does not offer a combined household-style fridge-freezer: each chamber is designed for its own temperature range, which matters for stability and uniformity.
0…+10 °C
CHS-C pharmaceutical refrigerators
Medicines and vaccines (typically +2…+8 °C), solid or glass door, microprocessor controller.
0…+15 °CCHL laboratory refrigerators
Samples and reagents in 12 single-chamber models from 74 to 1577 litres, Smart and Smart PRO controllers.
−25 / −40…0 °CLaboratory freezers
ZLN 85, ZLN-T and ZLW-T for long-term storage, plasma and pre-freezing.
−86…−50 °CZLN-UT ultra-low freezers
VIP insulation, three capacities for biological material and vaccines requiring ultra-low temperatures.
0…+15 °C · ATEXATEX laboratory refrigerators
For safe storage of chemical samples in zones with a possible explosive atmosphere (Zone 2).
Power backupEmergency Power Supply
Battery systems providing 4 to 30 hours of refrigerator and freezer operation during a power outage.
Multi-chamberCombined units
Double and triple-chamber units, combining CHL, ST thermostatic cabinets and ZLN 85 freezers.
Transport · +20…−22 °CDometic transport refrigerators
Portable CFX5 compressor coolers from 25 to 55 litres, 12/24 V DC and 100–240 V AC.
0…+10 °C · 74–1397 l
CHS-C pharmaceutical refrigerators
For medicines, vaccines and light-sensitive preparations. Stainless steel interior, 0.1 °C setting resolution. Each capacity is available with a solid door and with a glass door (suffix A).
0…+15 °C · 74–1577 l
CHL laboratory refrigerators
Single-chamber refrigerators with forced air circulation, Smart or Smart PRO controller and solid or glass door options. Available in C (comfort) and P (premium) versions; the Smart controller has a 4.3" display and LAN, while Smart PRO has a 7" display with LAN and Wi-Fi for monitoring through LabDesk software.
−25 / −40…0 °C · 85–314 l
Laboratory freezers
ZLN 85 and ZLN-T with natural convection, and ZLW-T with forced air circulation for better uniformity and faster cooling of the load.
−86…−50 °C · 259–482 l
ZLN-UT ultra-low freezers
Vacuum VIP insulation, natural convection and Smart or Smart PRO controllers. For biological material and products requiring ultra-low temperatures.

ATEX laboratory refrigerators
CHL refrigerators for safe storage of samples that may create an explosive atmosphere, built to ATEX Directive 2014/34/EU, marking II 3/- G Ex h IIC T6 Gc/-. Zone classification is defined by the employer through risk assessment.
Emergency Power Supply
A dedicated battery backup system for refrigerators, thermostatic cabinets, cooled incubators and freezers during power outages. It helps maintain the cold chain of medicines and vaccines for outages of 4 to 30 hours. A classic computer UPS is not sufficient because the compressor draws a multiple of its rated current at start-up; POL-EKO units tolerate 300% overload for 20 s. Standard: inverter with charger, battery, braked casters, visual and audible signalling, type E (230 V) socket.
Chamber combinations
Multi-chamber units
Double and triple-chamber CHL units and combinations with ST thermostatic cabinets and a ZLN 85 freezer in one housing. Multi-chamber units must be anchored to a wall.
+20…−22 °C · 25–55 l
Dometic CFX5 transport refrigerators
Portable compressor coolers for moving samples, reagents and temperature-sensitive goods in the field and in a vehicle. They run on 12/24 V DC from a vehicle and 100–240 V AC, with VIP insulation and app-based temperature monitoring. They are intended for general use: if transport is part of a validated cold chain, temperature must be qualified and mapped separately under real conditions.
Cold chain validation
From refrigerator to evidence.
The unit is only the first step. For medicines, vaccines and temperature-sensitive samples it matters to prove that the cold chain stays within the specified limits, and that proof is built through mapping and qualification.
Uninterrupted temperature control
Storage, transport and dispensing without leaving the specified range, supported by alarms, data logging and a response to deviations. A refrigerator with a microprocessor controller and alarms is the foundation of the chain.
Temperature distribution in the chamber
Measuring temperature at multiple points in an empty and a loaded chamber reveals the warmest and coldest spots, behaviour on door opening and power failure, and a suitable placement of sensors and shelves.
IQ · OQ · PQ
Installation, operational and performance qualification documents that the unit performs to user requirements under real conditions. The results are part of cold chain process validation.
What the path to validation looks like.
Scope and execution depend on user requirements, internal procedures and applicable regulations. APICAL helps with planning, while measurements and documentation are carried out by qualified specialists.
POL-EKO offers Smart and Smart PRO controllers (LAN, USB, plus Wi-Fi on Smart PRO), independent temperature recorders with SMS notification, LabDesk software (including a CFR 21 Part 11 compliant version) and calibration in its own accredited measurement laboratory. Option availability is confirmed per model. The above are general guidelines; actual requirements are defined by applicable regulations (e.g. GDP/GMP) and your quality system.
- 1User requirements
Define the goods, temperature range, capacity and criticality of storage (URS).
- 2Installation and IQ
Place the unit and verify connections, sensors, alarms and documentation.
- 3Mapping and OQ/PQ
Temperature mapping of the empty and loaded chamber, alarm tests, door opening and power failure tests.
- 4Monitoring and calibration
Continuous recording and alarming, periodic calibration and requalification as planned.
