Frequently Asked Questions
How does the heating process work in these units?
Air is drawn in by a centrifugal blower and passed over a series of specially designed electric heating elements. As the air moves through the heater housing, it absorbs thermal energy and is discharged at the desired temperature.
What is the maximum temperature an Electric Hot Air Generator can reach?
Our standard models at indianboilers.com typically achieve temperatures up to 250°C. However, we can custom-engineer units for high-temperature applications requiring up to 400°C or more.
Is the hot air produced safe for direct contact with food or medicine?
Yes. Since there is no combustion of fuels like oil or coal, there are no flue gases, soot, or carbon monoxide. The air remains 100% pure, making it ideal for "direct-to-product" drying.
How efficient are these generators compared to oil-fired ones?
Electric hot air generators are nearly 99% efficient because there are no stack losses (heat lost through a chimney). Almost every kilowatt of electricity used is converted directly into heat.
Can I control the temperature precisely?
Absolutely. Our units come with advanced control panels (PID or Thyristor-based) that allow for precision control within ±1°C, which is critical for sensitive industrial processes.
What capacities (kW) do you offer?
We offer a wide range of capacities starting from small 15 kW units up to large-scale 500 kW+ industrial systems, depending on your air volume and temperature requirements.
Can these units handle high air volumes (CFM)?
Yes. We design the heater housing and blower specifications based on your required Cubic Feet per Minute (CFM) to ensure the air reaches the target temperature at the necessary flow rate.
What power supply is required?
Most industrial models require a 3-phase, 415V, 50Hz power supply. We can also customize units for different voltage requirements for international clients.
Is it possible to recirculate the hot air?
Yes. Our designs can be configured for recirculating systems, which significantly saves energy by reheating air that is already warm rather than heating fresh ambient air.
Why is this generator preferred in the Pharmaceutical industry?
It is the gold standard for tablet coating and powder drying because it guarantees zero contamination, which is a mandatory requirement for GMP (Good Manufacturing Practice) standards.
Can it be used in the Food and Beverage sector?
Yes, it is widely used for dehydrating fruits, vegetables, spices, and grains, where maintaining the original aroma and color of the product is essential.
Is it suitable for the Textile industry?
It is perfect for specialized fabric curing, printing, and drying processes where uniform heat distribution is required to prevent damage to the material.
Does it require a chimney or a separate boiler room?
No. Because there are no emissions, you do not need a chimney or a dedicated boiler house. This saves significant space and reduces civil construction costs.
What safety features are built into your Electric Hot Air Generators?
At indianboilers.com, safety is paramount. Units include:
- Airflow Interlock: Heaters won't turn on without the blower.
- Over-temperature Cut-off: Prevents element burnout.
- Emergency Stop: For instant manual shutdown.
How long do the heating elements last?
With proper airflow and maintenance, our high-quality Ni-Cr (Nickel-Chromium) elements are designed to last for several years of continuous operation.
What maintenance is required?
Maintenance is minimal. It generally involves cleaning the air filters, checking electrical terminal tightness, and ensuring the blower motor is lubricated.
Are spare parts easily available?
Yes, we maintain a full inventory of heating elements, sensors, and blowers at our Ahmedabad facility to ensure minimal downtime for our customers.
How long does it take to install a unit?
Our units are "Plug & Play." Once delivered, they only require electrical and ducting connections, which can usually be completed within 1–2 days.
