Air Heaters

INTRODUCTION

The GGES Solar Air Heating System is designed to generate hot air using solar energy through Flat Plate Collectors similar to Solar Water Heater panels, designed and manufactured specifically for air heating applications. The system integrates collectors, blower, ducting, and process control to deliver con- sistent and efficient industrial hot air.

SYSTEM OVERVIEW

The system uses specially designed Flat Plate Solar Air Collectors where ambient air flows through spe- cially designed channels with high-absorptivity coated absorber. Solar radiation heats the absorber sur- face, transferring thermal energy directly to flowing air.

A centrifugal blower forces ambient air through the collector array. The heated air is then delivered via insulated ducting to the industrial process, drying chamber, space heating system, or pre-heating appli- cation.

MAJOR COMPONENTS

•Flat Plate Solar Air Collectors with transparent cover and insulated casing

•High efficiency absorber plate with air flow channels

•Centrifugal blower / fan with optional VFD control

•GI/MS insulated ducting with dampers

•Temperature/Pressure sensors and control panel

•Hybrid backup integration (Electric / Steam / Furnace) if required

HOW DOES IT WORK?

1.Ambient air is drawn into the system through the air intake section.

2.The blower pushes air through Flat Plate Solar Air Collectors.

3.Solar energy heats the absorber plate.

4.Heat is transferred to the flowing air inside the collector channels.

5.Hot air is collected in the outlet header duct.

6.Heated air is supplied directly to the industrial process.

7.During low solar radiation, hybrid backup ensures uninterrupted operation.
