Range logic

Products are differentiated by temperature, equipment class, net volume and control system:

Series	Temperature range	Configurations	Selection note
Evermed PDF	−25…−40 °C	270, 370, 440, 530 and 625 L; LITE or ADVANCED	Standard laboratory range with forced-air circulation and automatic defrost. Where medical-device status is required, verify documentation or use the separate PDF MD range.
Antech MDF-40U	down to −40 °C	Upright models in several sizes	Compare net volume, chamber organisation, alarms and monitoring interfaces for the exact model.
Vestfrost VT	down to −45 °C	Upright freezers	For applications needing additional temperature margin; final intended use depends on model documentation.

How to select

Use and documentation. Laboratory samples and plasma storage may have different requirements. Establish whether medical-device status, data logging or validation is required.
Net volume. Compare internal rather than gross volume and allow for shelves, containers, air gaps and future growth.
Controls. Evermed LITE provides an LED display, alarms and a dry contact. ADVANCED adds a 7-inch touchscreen, data and event logs, USB and backup power for the display and alarms.
Monitoring. Define requirements for dry contacts, external loggers, remote alerts and data export.
Installation. Check dimensions, doorways, ventilation clearances, power supply and room temperature.

Evermed PDF and PDF MD are different ranges

Standard PDF is a laboratory range. PDF MD is Evermed’s separate medical-device range for plasma and cryoprecipitate. Regulatory or tender requirements must be confirmed for the supplied configuration.

Frequently asked questions

What is the difference between Evermed PDF LITE and ADVANCED?
LITE provides basic LED controls, alarms and a dry contact. ADVANCED adds a touchscreen, temperature and event logs, USB and backup power for the display and alarms.

Can standard Evermed PDF be used for plasma?
Standard PDF is a laboratory range. Where plasma storage requires medical-device status, verify applicable requirements and supply documentation or select PDF MD.

How should freezer volume be selected?
Use net volume, packaging format, air gaps, loading frequency and growth allowance. Final capacity should be checked against the chamber layout.

Configuration and documentation
