The heart of the NATURE HDCOLD system monitors all the parameters in the cell through environmental sensors.

The PLC then automatically regulates the ventilation of the air coolers while maintaining optimum conditions.

Environmental sensors accurately measure all parameters with meticulous 100% RH control, without the formation of vapour.

For a NATURE HDCOLD system, a small compressor is sufficient, with savings in the order of 40% compared to a traditional system.

NATURE HDCOLD avoids total defrosting.

The system does not require the addition of moisture.

NATURE HDCOLD is a cost-effective solution, in terms of both initial investment and operating costs.

The whole system is managed by a PLC system with remote control.

The system is patented.

Each fruit has its own precise setting to maximize conservation results.
