Model PR-L5181GW-PA Features

Temperature Control Precision

This biomedical refrigerator features precise temperature control engineered to meet the current and evolving criteria for vaccine storage while requiring less energy than traditional undercounter refrigerators. The purpose-built PR-L5181GW-PA is designed to maintain the high performance necessary for valuable inventory.

Ease of Use and Accessibility

The PR-L5181GW-PA is designed with a compact footprint for functional workspaces and fits under most tables, cabinets and lab benches. A convenient glass door provides visibility into the interior of the unit to avoid unnecessary door openings. If the door is left ajar, the self-closing mechanism mitigates scenarios that could result in lost product. An optional stacking accessory is available to maximize storage capacity when space constraints become a concern.

Temperature Uniformity Even When Full

Many high performance refrigerators can maintain precise temperatures when they are empty. The PR-L5181GW-PA undercounter medical refrigerator has been designed to maintain high performance temperature uniformity of ±3°C even when loaded, as often occurs during peak vaccine season.

ENERGY STAR® Certification and Sustainability

The PR-L5181GW-PA undercounter medical refrigerator is ENERGY STAR Certified for performance and efficiency. ENERGY STAR uses independent testing by nationally recognized third-party laboratories to ensure energy efficiency and sustainability without compromising performance. The PR-L5181GW-PA biomedical undercounter refrigerator has a daily energy consumption of 0.42 kWh/cu.ft.i

Traditional refrigerants have been replaced with environmentally friendly natural refrigerants to meet Environmental Protection Agency (EPA) Significant New Alternatives Policy (SNAP) guidelines and the AIM Act of 2020 for low global warming potential and no ozone-depleting substances.

Microprocessor Control and Alarm

The unit has a door-mounted control with an easy-to-view LED display that features preset automatic alarm tracking around the temperature setpoint. The alarm is set at +3°C above and below setpoint, consistent with vaccine and high-value product storage requirements.

Cycle Defrost System

The PR-L5181GW-PA does not rely solely on a time-based system. Instead, the refrigerator utilizes a sophisticated defrost cycle that only triggers when needed and when the compressor is not running, minimizing temperature spikes often associated with common defrost systems. This innovation provides assurances of optimum temperature control maintenance at all times.

Undercounter Refrigerator

The PR-L5181GW-PA high performance glass door undercounter refrigerator is designed to maintain the +5°C temperature setpoint and ±3°C uniformity necessary for critical vaccine storage and the storage of biologics. This model is engineered to meet CDC guidelines in a small footprint. Precision temperature control and uniformity prevent the interior from cooling below freezing and risking vaccine and biologic viability whether the unit is loaded or empty.
