Model PF-L5181W-PA Features

Temperature Control Precision

This freezer features precise temperature control engineered to meet the current and evolving criteria for vaccine storage while requiring less energy than traditional undercounter medical freezers. The purpose-built PF-L5181W-PA is designed to maintain the high performance necessary for valuable inventory using the latest inverter compressor speed technology for optimum control.

Ease of Use and Accessibility

With a compact footprint, the PF-L5181W-PA is designed for functional workspaces and fits under most tables, cabinets and lab benches. The solid door protects light-sensitive materials. If a door is left ajar, the self-closing mechanism mitigates scenarios that could result in lost product. An alarm provides an even deeper level of protection. An optional stacking accessory is available to maximize storage capacity when space constraints become a concern.

Temperature Uniformity Even When Full

Many high performance vaccine storage freezers can maintain precise temperatures when they are empty. The PF-L5181W-PA vaccine freezer has been designed to maintain high performance temperature uniformity of ±5°C even when loaded, as often occurs during peak vaccine season. This model features evaporator shelving and forced air circulation within the chamber to ensure swift temperature pull-down upon startup and rapid recovery after door openings.

Energy and Sustainability

This ENERGY STAR Certified undercounter biomedical freezer provides energy efficiency and sustainability without compromising performance. Traditional refrigerants have been replaced with environmentally friendly natural refrigerants to meet 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.

Manual Defrost System

The PF-L5181W-PA is a manual defrost high performance undercounter medical freezer. This ensures that sensitive frozen enzymes or vaccines are not exposed to temperature deviation common with freezers containing an auto defrost cycle.


ENERGY STAR Certified Undercounter Freezer

The PF-L5181W-PA high performance undercounter freezer is designed to maintain temperatures between -15°C and -25°C with a tight uniformity of ±5°C for storing critical vaccines and biologics. This model is engineered to meet CDC guidelines in a small footprint. Precise temperature control and uniformity protect vaccine and biologic viability whether the unit is loaded or empty.
