Grain Dryers Units

Grain Dryers Units with Long-Distance Air Supply and Moisture-Friendly Cooling
Hisurp's Grain Dryers Units are designed for modern grain depots that need effective cooling, wide-area air distribution, and better grain moisture protection during storage. It is suitable for grain warehouses, reserve depots, cereal storage buildings, and agricultural storage projects where preserving both grain quality and storage efficiency is important.
Compared with ordinary HVAC equipment, this system is specially designed around the operating realities of grain storage. It addresses the major issues that standard air conditioners often fail to solve, including fumigation gas corrosion, dust accumulation, excessive dehumidification, and poor airflow coverage in large storage rooms.

Developed to Solve the Three Main Problems in Grain Storage Cooling

Hisurp developed the Grain Dryers Units to solve three major challenges commonly faced in temperature-controlled grain storage:

Corrosion During Fumigation

Corrosion During Fumigation

When grain warehouses undergo fumigation, corrosive gases can damage conventional copper components, motors, sensors, and control systems. Hisurp addresses this with specialized corrosion-resistant design and patented evaporator technology.

Dust During Grain Handling

Dust During Grain Handling

Large amounts of dust are generated during grain loading and unloading. This can clog heat exchangers and reduce HVAC performance. Hisurp uses design measures such as wider fin spacing and application-specific structure to reduce dust-related performance problems.

Moisture Loss During Cooling

Moisture Loss During Cooling

Traditional air conditioners often remove too much moisture while lowering air temperature. In grain storage, this can result in unnecessary grain drying and weight loss. Hisurp’s high sensible cooling design helps cool the warehouse while better preserving grain moisture.

Product Features

High Sensible Heat Ratio

Moisture-Friendly Cooling Strategy

Powerful Airflow for Large Warehouses

The system can provide approximately 3200 m³/h air volume and a 25–30 m air supply distance, helping create a more uniform temperature field inside large warehouse spaces. Uniform cooling improves the overall effect of grain preservation.

Patented Anti-Corrosion Technology

Hisurp’s patented magnesium-aluminum alloy evaporator helps solve the corrosion problems that phosphine can cause to traditional copper parts. The unit also uses a fully sealed supply fan design to help prevent motor corrosion.

Wide Fin Spacing Design

The heat exchanger uses a wide fin spacing design to reduce the risk of blockage caused by dust and debris, improving suitability for grain handling environments.

Intelligent Operation Control

Recommended Installation Approach

For easier dust cleaning and routine maintenance, floor installation is generally recommended. To improve energy efficiency, the outdoor unit is preferably installed on the shaded side of the warehouse. Outdoor units can be placed on the ground or on a canopy structure depending on the project layout.

Indoor air outlets may be designed with adjustable double-layer louvers or with ducted top supply according to required air throw distance and warehouse size. Through proper duct arrangement, the system can achieve more even air distribution across large grain storage areas.

Typical Applications

Hisurp’s Grain Dryers Units are suitable for:

  • Grain reserve warehouses
  • Rice depots
  • Wheat and corn storage buildings
  • Cereal storage centers
  • Agricultural logistics storage
  • Food grain preservation projects
  • Large warehouse-style grain storage facilities
