Solar-powered refrigerators and freezers

FREECOLD by COLDINNOV solar-powered refrigerators and freezers, preserve foodstuffs using the energy of the Sun

Cooling foodstuffs to preserve them before eating or selling them is a necessity. However, in areas not yet connected to a reliable electricity grid, it is still a luxury today.

FREECOLD by COLDINNOV solves this problem by selling solar-powered refrigerators and freezers.

The principle

As soon as the Sun appears, even for a few minutes, the system produces cold. The only energy consumed is solar energy via a photovoltaic panel. Our process makes it possible to use this energy to supply a compressor directly without a battery or voltage regulator. The electronic management module, with variable input voltage 10/42 VDC, allows the refrigeration unit to be operational as soon as a the Sun appears.

The refrigerators and freezers of the FREECOLD® range have a A++ class superior insulation quality. They are also equipped with an aluminum inner tank for a better distribution of cold in the enclosure.

These features allow our solar refrigerators and freezers to be of SN-T climate class. They have been specially designed to operate in extreme temperature conditions up to 43°C. They are therefore perfectly adapted to the tropical and desert climates present in Africa and South America for example.

High modularity

Most of our refrigerators and freezers can also work with a hybrid power supply. They can be powered:

  • In direct solar with electricity storage by 12/24 VDC solar lead batteries
  • Via the 220 VAC electricity grid, when available

Some of our products go even further and produce battery-less refrigeration. Here, solar energy is stored in the form of cold using to a specially designed eutectic module: the FREECOLD Ecotainer®. This COLDINNOV innovation allows for the storage and delayed redistribution of cold. As a matter of fact, it is slowly diffused during the night or during days without Sun in order to keep an optimal temperature of conservation. Everything has been designed to optimize the distribution of cold in the inner tank by confining it around the eutectic container. This original set, core of the FREECOLD® system is subject to industrial protection by a patent.

Delivery and warranty

Our refrigerators and freezers are delivered pre-loaded and ready to install. The photovoltaic installation is optional. For any question, contact us!

The warranty is 1 year, parts and labor included.

RSI-180 battery-less solar refrigerator

Réfrigérateur solaire sans batterie FREECOLD RSI-180

The FREECOLD® RSI-180 direct solar refrigerator has a net volume of 155 L and a very good thermal insulation.

Its main feature: it is directly connected to a photovoltaic module without additional electronics! This innovative system makes it possible to do without batteries or inverter, costly and with a limited lifespan.

The excess energy of the day is transformed and stored, not in batteries, but in a cold accumulator built into the heart of the evaporator: the FREECOLD Ecotainer®. This cold is then slowly diffused in the refrigerator during the night and days without sun. This allows to maintain the quality of the cold in autonomy for 3 to 4 days depending on the ambient temperature.

FREECOLD® 3-way refrigerators and freezers

FREECOLD RFO-85 3-ways solar refrigerator

The FREECOLD® RFO-85 refrigerator as well as the CFO-65 freezer are 3-way products. This means that they can be connected simultaneously to three different power supply sources: photovoltaics, 230 V grid and 12 or 24 V external battery. Switching from one source to another is automatic, with priority for photovoltaics.

They both have a good net volume: 85 L for the refrigerator and 65 L for the freezer. Their main advantage however lies in their small width of 47.5 cm. This extreme compactness adapts perfectly to all domestic and leisure applications (motorhomes, caravans, pleasure boats, …).

They are also very well suited for storing vaccines and medicines in tropical areas where the power grid is subject to frequent breakdowns.
