Model PR-L5181W-PA Features

Purpose-Built Cold Chain Storage

PHCbi brand undercounter refrigerators are engineered to create, maintain and restore precise temperatures necessary for vaccine storage. Our purpose-built vaccine storage refrigerators are designed for temperature uniformity and stability that is not commonly found with household or commercial cabinets. PHCbi brand vaccine refrigerators satisfy current and evolving storage guidelines essential for vaccine cold chain storage.

Meeting Regulatory Standards

The PR-L5181W-PA features precise temperature control engineered to meet the current and evolving criteria included in the CDC, NSF and ANSI guidelines for vaccine storage while requiring less energy than traditional undercounter refrigerators.

Compact Design

With a compact footprint, the PR-L5181W-PA is designed for functional workspaces and fits under most tables, cabinets and lab benches. An optional stacking accessory is available to maximize storage capacity when space constraints become a concern.

High Performance

The purpose-built PR-L5181W-PA is designed to maintain the high performance necessary for valuable inventory. This biomedical undercounter refrigerator has been designed to maintain high performance temperature uniformity of ±3°C even when loaded, as often occurs during peak vaccine season. The solid door protects light-sensitive materials. The self-closing mechanism mitigates scenarios that could result in lost product if a door is left ajar.

Microprocessor Controller and Alarms

The unit has a door-mounted control with an easy to view LED display that features a 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-L5181W-PA undercounter refrigerator utilizes a sophisticated defrost cycle, which provides assurance of optimum temperature control maintenance at all times. The cycle defrost system only triggers when needed and when the compressor is not running, minimizing temperature spikes often associated with common defrost systems.

ENERGY STAR® Certification and Sustainability

The PR-L5181W-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-L5181W-PA biomedical undercounter refrigerator has a daily energy consumption of 0.31 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.

Access Port and Security

The 1.2" (30 mm) access port permits the passage of external temperature monitoring probes through the chamber without intruding on the door gasket. The door includes an integrated key lock.

Small Medical Refrigerator

The PR-L5181W-PA is engineered to meet the strict regulatory guidelines of the CDC, ANSI and NSF. The laboratory undercounter combines high performance temperature control with environmentally friendly refrigerants and energy efficiency. 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.
