Low RH Cold Storage

Humidity and temperature control are critical factors in cold storage. Especially for seed storage, optimum conditions are necessary to maintain viability and avoid discolouration, fungus growth, and toxin production. Even in a dormant state, seeds continue to undergo metabolic processes, which is also known as ageing. If the humidity is too high, ageing or deterioration can start, whereas too low humidity can lead to a decline in the viability or vigour of the seed. That is why the external environment plays a key role in the prolonged or long-term storage of seeds.

What is Low Relative Humidity Cold Storage?

It's a climate-controlled facility engineered to keep moisture levels consistently low, typically below 65-70%. It is primarily used for the long-term preservation of seeds, pharmaceuticals, and confectionery products, where precise humidity control is required to prevent mold growth, sprouting, and product degradation.

These low RH cold storages not only reduce the operational and maintenance costs but are also eco-friendly! They are equipped with:

A single system to control temperature and humidity
SST up to –15℃
A coil designed for high humidity applications
Strip heaters
Hot gas provision for defrost
Scroll or semi-hermetic compressor
Evaporator fan speed regulation
CFC-free refrigerant

Frequently Asked Questions

Q1. What is a Low RH cold storage?

Low RH cold storage is a specialized environment-controlled system designed to keep humidity levels consistently low, typically below 65-70%. These facilities are critical for products sensitive to moisture, such as seeds, pharmaceuticals, and confectionery, where even slight humidity fluctuations can lead to mold growth, clumping, or degradation of chemical properties.

Q2. Why is humidity control critical in seed storage?

In seed storage, precise humidity control is vital to prevent premature ageing, fungus growth, and toxin production. High moisture levels can trigger metabolic processes that reduce the seed’s viability and vigor. Blue Ice India’s low RH solutions ensure seeds remain dormant and healthy, preserving their germination potential for long-term agricultural use.

Q3. How does Blue Ice maintain low RH without an external dehumidifier?

Our low RH systems utilize a specialized internal coil design and integrated automation to stabilize humidity levels naturally through the refrigeration cycle. By eliminating the need for a separate external dehumidifier, we help businesses save up to 40% on capital investment while achieving superior moisture control for sensitive industrial products.

Q4. What are the features of Blue Ice low-RH cold storage?

Key features of our low-RH solutions include SST up to –15°C, high-performance coils, integrated strip heaters, and hot gas defrosting systems. We also utilize energy-efficient scroll compressors and CFC-free refrigerants, making our systems eco-friendly and cost-effective for large-scale industrial cold room installations in Ahmedabad and across India.

Q5. Who can benefit from low-RH cold storage solutions?

Pharmaceutical companies, seed manufacturers, and confectionery businesses (such as chocolate and candy manufacturers) benefit most from low-RH storage. These systems prevent moisture damage to medicines, maintain the texture of chocolates, and ensure seed longevity, making them an essential investment for any industry requiring strict, dry, and cold atmospheric conditions.
