Hot Air Generator

Introduction

A Hot Air Generator is an industrial equipment system designed to produce a large volume of heated air for drying, curing, space heating, and process heating applications. Kerone manufactures robust and energy-efficient Hot Air Generators that operate on various fuels including natural gas, LPG, diesel, biomass, and electricity. Our hot air generators are engineered to deliver consistent, high-volume airflow at precisely controlled temperatures, making them ideal for industries such as textile drying, food processing, chemical manufacturing, pharmaceuticals, and agricultural product drying. Kerone’s systems are available in direct-fired and indirect-fired configurations to suit both clean-air and process-air requirements.

The heavy, industrial construction and precise airflow handling of the hot air generators are designed to handle abrasive and harsh working environments, while providing continuous and effective working lines. We are having immense experience in providing customized machinery to suit various industrial requirements of our esteemed clients meeting the industry’s requirements for intense and rigid equipment design. The dryers manufactured by KERONE are made with high quality internal and external material by taking discreet efforts for the perfect size and desired operations.

Types and Features of Hot Air Generator

A fully automatic multi pass counter current Hot Air Generator consist of stainless steel shell type integral combustion chamber accommodated in multi M.S. shell. The cold air is inserted by a suitable capacity blower fan in first pass, absorbs heat from flue gas passage and accordingly both hot flue gas and cold air travel in opposite direction in the passage which ultimately transfers 90% heat to cold air and delivers hot air from hot air outlet hole. The system functions fully automatic on temperature sensing device installed at hot air outlet which ON-OFF the burner at pre-set temperature. the system is a package type unit, fixed on common base frame.

We offers Hot Air Generators in several configurations including Direct Fired Hot Air Generators (for applications where combustion products can contact the process), Indirect Fired Hot Air Generators (for clean hot air applications via heat exchanger), Electric Hot Air Generators (for clean rooms and pharmaceutical environments), Biomass-Fired Hot Air Generators (for sustainable and low-cost heating), Oil/Gas-Fired Hot Air Generators (for high-capacity industrial applications), and Skid-Mounted Mobile Hot Air Generators (for temporary or portable heating requirements).
