Silo Granary Storage Cooler

In modern grain preservation systems, temperature management is more than comfort cooling. It directly affects grain respiration, pest activity, mold growth, storage loss, processing quality, and long-term commercial value. Hisurp’s silo granary storage cooler helps create a more stable storage environment by lowering and maintaining warehouse temperature while reducing unwanted moisture loss from stored grain.

Many storage operators initially try to use ordinary air conditioning systems to cool grain warehouses. Although this may provide short-term temperature reduction, traditional units often show major weaknesses over time in grain storage applications.

Common problems include:

• Corrosion caused by fumigation gas such as phosphine
• Heavy dust impact during grain transfer operations
• Excessive latent cooling and condensate generation
• Grain moisture loss during prolonged operation
• Uneven air supply in wide storage rooms
• Poor suitability for green storage and low-temperature preservation strategies

A grain silo air conditioner is therefore necessary because grain storage requires a system designed for agricultural preservation, not a standard comfort air conditioner adapted after installation.

Anti-Corrosion Design for Grain Storage Environments

Grain fumigation environments can expose HVAC equipment to corrosive gases such as phosphine. Hisurp’s grain silo air conditioner uses multiple protection measures to improve durability in such conditions:

• Anti-corrosion coating on key surfaces
• Sealed motor treatment
• Resin sealing at lead-out wire positions
• Control circuits arranged in outdoor areas less exposed to corrosive gas
• High anti-corrosion coating on indoor temperature sensor surfaces

These measures help improve equipment life and reduce maintenance risk in grain warehouses.

High Sensible Heat Ratio to Protect Grain Moisture

A major advantage of this system is its high sensible heat ratio design. According to test data, around 90% of the cooling capacity is used directly for air temperature reduction, while conventional air conditioners generally provide only 65%–70% sensible cooling.
This means the system cools grain storage air more effectively while reducing excessive dehumidification. As a result, it helps preserve grain moisture and reduces the risk of unnecessary weight loss and quality decline.

Large Air Volume and Long-Distance Air Supply

Standard grain storage buildings can be wide and difficult to cool evenly. Hicon’s unit adopts a directional air outlet design with:

• Large air volume
• Long air throw distance
• Effective air supply distance up to 16 m
• Maximum throw distance around 24 m

This supports more uniform airflow distribution across the grain warehouse and improves the consistency of the storage temperature field.

Remote and Local Control

The unit supports single unit control and remote centralized control.

Hicon's silo granary storage cooler can be used in:

• Grain depots
• Grain warehouses
• Cereal storage rooms
• Rice storage facilities
• Wheat storage buildings
• Corn storage warehouses
• Agricultural reserve storage facilities
• Food grain logistics centers

To match different grain warehouse structures and project conditions, Hisurp can provide multiple installation forms, including:

• Split horizontal type
• Split cabinet type
• Outdoor-installed split type
• Packaged type
• Low-height horizontal packaged type

Outdoor installation helps reduce the risk of indoor condensate leakage and is practical for warehouse cooling systems where maintenance access and corrosion control are important.
