We are engaged in manufacturing & exporting Internally Heated Air Dryer, which is an improvised version of heatless dryer. In this type of heatless dryer purge air loss is very less. Because of low pressure and at high temperature the regeneration is achieved by dry air. This hot purge air at low pressure is passed through the desiccant bed to regenerate with small quantity of purge.

Features:

• Saving in purge air loss
• Compact design
• Simple operation
• Advanced version of desiccant dryer

Additional Information:

• Delivery Time: 4 WEEKS

Additional Information:

• Production Capacity: 5
• Delivery Time: 12 WEEKS

We manufacture & export a wide range of Desiccant Air Dryer. First tower is used in drying and second tower is used in regeneration simultaneously. Part of dry air coming out from tower one and then goes for regeneration of the second tower and the whole process takes 5 minutes.

Features:

• Simple operation.
• Easy to maintain.
• No need of heater or cooler

We are the most established and reputed manufacturer and supplier of Split Flow No Purge Loss Air Dryer. In Split Flow No Purge Loss Air Dryer incoming wet air is divided in a distributor.This is primarily used to save on purge loss, here part of wet air is circulated through a heater thereby increasing its moisture carrying capacity. 60-70% of wet air goes for drying while 30-40% of wet air is circulated through a heater. This air is sent back to the distributor where it mixed with incoming air and distributed again.

Features:

• No purge loss.
• No need of blower.
• No used of external air thus eliminating risk of contamination.
• Most economical in the range from 400 CFM onwards

HEATLESS AIR DRYER:

This is the simplest of all desiccant based air dryers. In this dryer two desiccant towers are used. While one tower is in drying, second tower undergoes regeneration simultaneously. Part of dry air coming out from tower in-line goes for regeneration of the second tower. Tower changeover takes place at every 5 minutes by a sequence controller mounted in control panel.


Salient Features:

• Simple operation
• Easy to maintain
• Microprocessor based Controller with Purge Saver
• No need of heater or cooler
• Atmospheric dew point of (-) 40 to (-) 60 Deg C can be easily achieved. Simple operation

Price will vary according to capacity

The simplest way of removing moisture from compressed air is to reduce the temperature. In this dryer compressed air is passed through a heat interchanger where cold refrigerant at around 3 Deg C is passed through the other side of the heat interchanger. At this temperature most of the moisture is condensed which is then separated and drained out in moisture separator.

We offer a good variety of Mini Heatless Dryer. It has same features and specifications as that of Heatless dryer but is present in compact size.


Features:

• Simple operation
• Easy to maintain
• Microprocessor based Controller with purge saver
• No need of heater or cooler

A Regenerative Air Dryer is a type of compressed air dryer that removes moisture from compressed air using a desiccant material, which is periodically regenerated to maintain continuous drying performance.

Types of Regenerative Air Dryers

1. Heatless Regenerative Dryer

   • Uses a portion of dried compressed air (purge air) to regenerate the desiccant.
   • Simple and reliable but consumes about 15-20% of compressed air for regeneration.

2. Heated Blower Purge Dryer

   • Uses an external heater and blower to regenerate the desiccant without consuming compressed air.
   • More energy-efficient but requires an external power source.

3. Heat-of-Compression (HOC) Dryer

   • Utilizes the heat generated during the compression process for desiccant regeneration.
   • Best suited for oil-free air compressors and highly energy-efficient.

How It Works

• Compressed air flows through a chamber containing desiccant material (typically activated alumina, silica gel, or molecular sieves).
• The desiccant absorbs moisture, providing dry air with a low dew point (-40°C to -70°C).
• A second chamber regenerates the desiccant, either using purge air, external heat, or heat-of-compression.
• The system continuously switches between drying and regenerating cycles to provide an uninterrupted supply of dry air.

Advantages of Regenerative Air Dryers

✔️ Delivers very low dew points (up to -70°C/-100°F).
✔️ Essential for moisture-sensitive applications (pharmaceutical, food, electronics).
✔️ Prevents corrosion and contamination in air tools and pneumatic systems.

A No Purge Loss Air Dryer is a type of compressed air dryer that minimizes or eliminates the loss of compressed air during the drying process. This is particularly useful in applications where air conservation is critical.

Key Features and Benefits:

1. Zero Air Loss – Unlike traditional desiccant air dryers that use a portion of the dried air for regeneration, no purge loss air dryers prevent this wastage.
2. Energy Efficiency – Reduces overall energy consumption by utilizing external heat sources, blowers, or other means for desiccant regeneration.
3. Lower Operating Costs – Since there’s no compressed air loss, the system operates more efficiently, leading to cost savings.
4. Reliable Performance – Provides consistent dew point control and ensures dry, high-quality compressed air.
5. Types – Common designs include heated blower purge dryers, heat-of-compression dryers, and refrigeration dryers (which don’t use desiccant).

Applications:

• Manufacturing plants
• Pharmaceutical industry
• Food & beverage industry
• Automotive production
• Petrochemical and gas processing
