CHL Series — Laboratory Refrigerators, 0 to 15 °C

POL-EKO CHL Series laboratory refrigerators, CHL 1 C with SMART PRO controller

Applications

Commonly used for:

  • Storage of temperature-sensitive samples and reagents
  • Culture media and buffer storage
  • Pharmaceutical and clinical sample storage
  • Food and environmental laboratories
  • Quality control and research laboratories

Why POL-EKO® Laboratory Refrigerators?

POL-EKO® designs and manufactures the CHL series in Poland, and every refrigerator shares the SMART controller platform used across the company’s thermostatic range. One interface covers every unit in the lab, the same logging and connectivity is on all of them, and the cooling circuit is built and tested to a standard a general-purpose fridge does not reach.

What the CHL series gives you:

  • Universal, precise cooling from 0 to 15 °C (32 to 59 °F)
  • 0.1 °C resolution, with forced air circulation to remove warm and cold spots
  • Cooling components pressure-tested above 15 bar, with verified leak rates under 1 g per year
  • Full event logging in internal memory, with email alarm notification
  • Wi-Fi, USB, and LAN, with LabDesk software for traceable documentation

How the CHL Series Works

A CHL refrigerator is built as a laboratory instrument rather than a cold box. Forced air circulation evens the temperature across the chamber so there are no warm or cold pockets, automatic defrosting keeps ice off the evaporator during long runs at low temperature, and the controller holds the setpoint to 0.1 °C resolution anywhere from 0 to 15 °C.

The cooling circuit uses R1234ze, a refrigerant with a global warming potential of 7. Components are pressure-tested above 15 bar, and every cooling system is verified by high-pressure, vacuum, and leak-detection tests — POL-EKO® measures the resulting leak rate at under 1 gram per year for a single unit. Insulation is a high-performance HFO-blown foam up to 60 mm thick, which is what keeps the chamber stable and the energy draw down.

  • SMART PRO controller — 7″ full-color touchscreen designed in-house by the POL-EKO® engineering team, operated mainly through icons
  • Four-core 64-bit processor — 1.5 GHz with 4 GB RAM for fast response, smooth multitasking, and stable operation
  • Event logging and email alarms — every event written to internal memory, with alarm notifications sent to the addresses you designate
  • User Note — add personalized comments to recorded data for context, traceability, and clearer documentation
  • Startup self-diagnostics — critical components checked at every startup, with operation protected against loss of communication between peripheral units
  • Wi-Fi, USB, and LAN — three routes for data transfer, plus the LabDesk Cloud app for live status from a phone, tablet, or laptop

Alarms, Logging, and Remote Access

The controller writes every event to internal memory and sends alarm notifications to the email addresses you designate, so a deviation reaches you instead of waiting to be found. LabDesk software handles data management and unit performance monitoring and integrates with CFR 21 Part 11-compliant systems where traceable records are required. The LabDesk Cloud app shows live status and recorded data from any device.
