Industry Comparison

Application Scenarios

The ATPC Automatic Solar Hot Air Collector is widely used by:

• Distributors supplying industrial thermal equipment

• EPC contractors integrating renewable heating systems

• Engineering contractors for factory ventilation retrofits

• Architectural developers for green building projects

Typical applications include crop drying, timber seasoning, textile drying lines, warehouse heating, and process air preheating.

Core Pain Points and Solutions

• Unstable hot air temperature — solved by automatic damper and sensor feedback loops

• High fossil fuel heating costs — reduced by solar air preheating integration

• Complex installation requirements — simplified by modular collector design

• Corrosion in humid environments — addressed by aluminum alloy frames and coated back plates

Risk Warnings and Mitigation Recommendations

• Risk of insufficient airflow due to improper duct sizing — conduct airflow simulation before installation

• Overheating risk under low load — install automatic temperature relief and bypass dampers

• Weather sealing failure — perform annual seal integrity inspections

• Glass breakage from impact — use certified tempered solar glass and protective mounting angles

Procurement and Selection Guide

1. Confirm required airflow volume and target air outlet temperature

2. Calculate available roof or wall installation area

3. Verify compatibility with existing ventilation and duct systems

4. Request thermal efficiency test reports from suppliers

5. Check material certificates for glass, frame, and insulation

6. Evaluate automatic control system reliability and sensor accuracy

7. Assess installation load-bearing capacity of the building structure

Engineering Case Example

In a food drying plant retrofit project, the ATPC Automatic Solar Hot Air Collector system was installed with 120 modular collectors across a factory roof area of approximately 600 m². The system provided preheated air at 45°C–70°C to the main drying chambers, reducing fossil fuel consumption for air heating by approximately 35% and stabilizing inlet air humidity and temperature.
