I - Vertical Coil type forced Water circulation instant Steam / Hot Air Generators.

ii - Spirally wound Steam Coil concentrically placed within the assembly formed by outer shell and inner shell.

iii - The passage between inner shell and outer shell provided with the Radiator along with the Radiator itself act as a Combustion Air Preheater.

iv - The material of construction for Steam Coil is BOILER QUALITY STEEL.

v - Steam Coil hydraulically tested for pressure of 55 kg/cm2 applied for about 30 minutes.

vi - Burner components and Air Cone manufactured out of heavy gauge STAINLESS STEEL sheets.

vii - Blower provided with statically and dynamically balanced impeller for smooth operation.

viii - Economiser installed in such a way so as to RECOVER maximum possible heat from the flue gases.

ix - The control panel is SWITCH GEARED with easy available standard components from market to increase independence.

i - Fully automatic operation with ON-OFF modulation of Burner for smaller capacities and HIGH-LOW ON-OFF/continuous modulation larger capacities

ii - All the automatic operations are controlled through a control panel supplied along with the unit

ii - The Burner is of pressure atomizing type and self igniting maintaining CLEAN and SMOKELESS COMBUSTION throughout the operation

iii - Precisely tuned Air flow rate with fuel burning rates give accurate desired quantity of Air

iv - Modulating Burner ensures high efficiency and no wastage of heat

v - The unit operates in such a way that it burns only necessary quantity of fuel Oil proportional to heat demand from plant giving highest overall thermal efficiency

vi - A Digital Temperature Controller senses the heat demand in the plant and controls the Burner ON-OFF/HIGH-LOW modulation maintaining minimum fuel consumption

vii - In case of any abnormal operating condition the unit stops its function safely and goes to lockout by giving audiovisual alarm

viii - Instant Hot Air from cold start (within 15-20 min.) ensuring no loss of fuel and time during initial warming up period

ix - Shutting off period is also very small ensuring negligible residual heat loss at atmosphere

x - Simple starting and stopping formalities

Ideally suitable for batch processes as well as continuous operation

i - Flame failure device

ii - Low Air flow cutout

iii - Super heat controller

iv - Motor protection relays, fuses etc.

i - High overall thermal efficiency of 87% on GCV of fuel Oil and 94% on NCV of fuel Oil for stack temperature less than 250°C

ii - Three flue gas passes giving maximum total length of flue gas travel along with large residence time of gases ensuring a very effective heat transfer

iii - Extra large furnace volume giving complete combustion of Oil, with no Carbon formation and hence no maintenance

iv - Large radiation heat transfer area directly exposed to furnace promising high effectiveness of heat transfer area

v - Large overall heat transfer area and hence low heat flux densities

vi – Save up to 80% on energy costs compared to electrical heating

i - AIRPACK in conjunction with suitable drying chamber eliminates costly and maintenance prone Steam Boiler/Thermic Fluid based dryer. This saves 13% energy costs

ii - AIRPACK and drying chamber/drying oven combination saves 75-80% on energy bills compared to electrically heated dryers

iii - AIRPACK finds typical applications in Spray Dryers, Fluid Bed Dryers, Ovens, Curing Chambers, Drying Chambers etc. Such applications are in Textiles, Painting Industries, Bakery, Food Processing, Chemical Processing, Drying Systems
