Ice-lined vaccine refrigerators

A cold chain with stored cooling

Select a refrigerator and request a quote

Vestfrost VLS ice-lined vaccine refrigerators store cooling to maintain +2…+8 °C during power interruptions. The range includes mains-powered AC and solar SDD models, including combined RF units with a separate freezer for preparing water packs. Compare net storage volume, holdover or autonomy, and power source to select a model for your facility.

For model selection, prepare your required volume, outage duration and available power source.

Choosing a configuration

AC — mains power
For facilities with a mains electricity supply. Stored cooling helps maintain the temperature during power outages.

SDD — solar power
Solar Direct Drive runs on solar panels. Stored ice provides autonomy at night and during periods of insufficient solar energy; the solar kit depends on the specified configuration.

RF — refrigerator and freezer
The refrigerator stores vaccines at +2…+8 °C, while a separate 50 L freezer prepares water packs at −15…−25 °C. The freezer is not intended for biological sample storage.

Model comparison

AC values describe holdover without power; SDD values describe autonomy. Measurements are at +43 °C. Results are model-specific and do not guarantee the same duration for every loading pattern or lid-opening frequency.

Volume and holdover/autonomy values follow the Vestfrost datasheets. WHO registry data may differ by revision; for procurement, check the exact model, configuration and values against the documents in its row.

Configuration and procurement support

Agreed configuration

The quotation specifies the model and configuration, basket and water-pack quantities, temperature monitoring equipment and required options. For SDD, solar panels, mounting hardware, cables and installation requirements are agreed separately.

Procurement documents

Datasheets and WHO PQS evidence are available in the table. Specify your requirements for the product passport, user manual, document language and temperature monitoring so the document package can be agreed before ordering.

Installation and service

Delivery, commissioning, staff instruction and service support can be arranged. Lead times, scope of work and warranty terms are specified in the quotation and contract.

Temperature retention during power outages: questions and answers

What is an ice-lined refrigerator (ILR)?

An ice-lined refrigerator stores ice around the vaccine compartment. When power is interrupted, the ice gradually melts and absorbs heat, helping maintain +2…+8 °C.

How long does a refrigerator stay cold without power?

Duration depends on the model; compare the values in the table above. AC values describe holdover without power, while SDD values describe autonomy during insufficient solar energy. Data are measured at +43 °C; actual duration also depends on stored cooling, loading and lid openings.

Does the backup battery power the compressor?

A monitoring battery should not be treated as backup power for the compressor: it supports temperature monitoring and alarms according to the model configuration. Stored ice provides cold retention during power interruptions.

How can I obtain a price and order a suitable model?

Tell us the required net storage volume, typical outage duration and power source — mains or solar panels. Also specify whether you need water-pack freezing, a temperature logger and a solar kit. These details help define the configuration and prepare a quotation.
