The ZLN-T 300 series is a laboratory-grade ultra-low freezer manufactured by POL-EKO Aparatura and offers a 310-liter storage capacity within the -40…0°C temperature range. The primary distinction between Smart and Smart PRO models lies in the control display size (4.3" or 7" touchscreen) and connectivity options (Smart PRO includes WiFi in addition). The unit provides balanced cooling over specimens through natural air convection and delivers energy efficiency via polyurethane foam insulation.

The inner chamber is fabricated from stainless steel (DIN 1.4016/1.4301) and accommodates reinforced perforated shelves, with 3 shelves standard and up to 6 shelves supported. Each shelf supports 10 kg, with standard product load capacity of 80 kg, extending to 160 kg with the reinforced PW option. DIN 12880 Class 3.2 over-temperature protection is offered as an optional feature, a critical specification for laboratories requiring high sample integrity.

Utilizing R290 refrigerant (low GWP), the unit operates at 230V/450W and provides remote monitoring capabilities via LAN/USB connectivity (plus WiFi on Smart PRO). Weighing 185 kg, the unit is engineered for pharmaceutical storage, biological specimen preservation, and clinical laboratory applications.
