Air Gas Dryer, Membrane Dryer

Air Gas Dryer

In an ideal compressed air system air dyer is one of the most critical and important equipment. In general industry selects a dryer from the standard model of a dryer of any particular brand without knowing actual dryness ( Dew point) required for their application. As a result of this, sometimes over designed dyer will unnecessarily cost more in terms of its capital cost, operation and maintenance cost and sometimes less designed dryer will lead to frequent application, process and instruments failure,

Calorie-HNT specializes in following type of air dryers.

A. Refrigeration dryer
B. Regenerative Adsorption dryer
C. Membrane dryer

Regenerative Adsorption Type is further classified as

1. Heatless dryer
2. Internally Heated dryer
3. Externally Heated dryer
4. No loss Split Flow dryer
5. Heat of Compression dryer

REFRIGERATION DRYER

Principle

The temperature of the compressed air is brought down to 2-3 deg C in an heat exchanger through a refrigeration cycle. As a result of cooling moisture present in the compressed air gets condensed and knocked out in a moisture separator. Dry air having a pressure dew point (+) 3 deg C is available for use.

Process

The process is continuous and non cyclic. The saturated compressed air enters into a heat exchanger where it is partially cooled by the chilled air coming out from the moisture separator. This partially cooled air is further cooled down to (+) 3 deg C in the evaporator of the refrigeration cycle. A complete refrigeration systems which consists of a compressor, condenser, expansion valve and evaporator ensures the continuous cooling of the incoming compressed air. The systems is automatic with all relevant safety interlocks and proper instrumentation.  The moisture of the outgoing compressed air is knocked down in a moisture separator and drained out through and automatic drain valve.

Specifications

• Capacity -  100  to 15,000 Nm3/hr
• Pressure -  5 to 16 Bar (g) standard . ( Higher Pressure on demand)
• Pr.Dew Point -  (+) 3 deg C

 

It is very important for proper selection of air dryer. Selection depends upon many factors like capacity, pressure, Temperature, dew point, location, type of air compressor and mainly the application. A improper selection may cost in terms of capital investment and operational cost. Hence it is recommended to specify the complete details to Calarie.

Principle

The adsorption type dryers are also termed as desiccant dryers. Theses type of dryers are usually used where low dew point in the range (-) 40 deg C - (-) 80 deg C is required. A desiccant is used for the adsorption of moisture. It is twin column and cyclic process. When one column is in adsorption mode, the other is in regeneration mode. The regeneration of desiccant is done by heating the desiccant followed by subsequent cooling.  

HEATLESS DRYER

The principle is the same as explained above but in this case the desiccant is regenerated by small quantity of dry air itself. There is no heating is required, hence it is termed as Heatless. The dry air required for the regeneration is basically a loss of dry compressed air which is in tune of 7-12% for a consistent dew point of (-) 40 deg C. This loss is termed as purge loss. Since there is loss of dry air , it is only recommended for a smaller  capacities 

Specifications

• Capacity -  5 to 1000 Nm3/hr
• Pressure -  5 to 16 Bar (g) standard . ( Higher Pressure on demand)
• Pr.Dew Point -  (-) 40 deg C to (-) 73 deg  C

 

INTERNALLY HEATED DRYER

This type of dryer has electrical heater embedded inside the desiccant columns. These dryers are most suitable for the application where very low dew point in the range of (-) 60 - (-) 80 deg C is required. Regeneration of the desiccant is done by heating of the desiccant and purging with the small quantity of the dry air. 

Specifications

• Capacity -  50 to 8,000 Nm3/hr
• Pressure -  5 to 16 Bar (g) standard . ( Higher Pressure on demand)
• Pr.Dew Point -  (-) 40 deg C to (-) 80 deg C

 

EXTERNALLY HEATED DRYER

This type of dryer has electrical heater installed outside the desiccant columns. These dryers are most suitable for larger capacities beyond 500 Nm3/hr and for the application where  dew point i(-) 40 deg C is enough. Regeneration of the desiccant is done by heating of the desiccant and purging with the atmospheric air from an external air blower. There is NO LOSS of compressed air. 

Specifications

• Capacity - 500 to 15,000 Nm3/hr
• Pressure -  5 to 16 Bar (g) standard . ( Higher Pressure on demand)
• Pr.Dew Point -  (-) 40 deg C

 

NO LOSS SPLIT FLOW DRYER

This type of dryer similar to externally heated type but there is no external blower is required. The main stream of the compressed air is divided into two streams. The main stream enters one of the drying column and gets dried while a small portion of second stream is routed trough an external heater and enters into the second column for regeneration and after regeneration it combines with the main stream. The reaeration is done in a closed loop. In this dryer one regeneration cooler and one after cooler is used.   These dryers are most ideal for larger capacities beyond 500 Nm3/hr and for the application where  dew point i(-) 40 deg C is enough. 

Specifications

• Capacity -  500 to 15,000 Nm3/hr
• Pressure -  5 to 16 Bar (g) standard . ( Higher Pressure on demand)
• Pr.Dew Point -  (-) 40 deg C to (-) 80 deg C

The Heat Of Compression Dryer is an industrial product manufactured in India and is available in various sizes. Its sleek silver color makes it aesthetically pleasing and suitable for any industrial environment. This dryer has been specifically designed to remove the moisture present in compressed air, making it an essential tool for any industrial setup. The warranty provided adds to the reliability and trustworthiness of this product.

This type of dryer has virtually negligible operational cost as compared to other dryers. It is again a no loss type and no heater is required for regeneration. In fact the hot air  coming out from the compressor itself is sufficient for the regeneration. But the minimum temperature should be 120 deg C. This temperature is not possible for smaller capacity compressor , hence HOC type dryer is for larger capacity. This dryer is always installed near the compressor so as to use maximum heat. In this dryer, first of all the hot air from the compressor enters into one column and picks up the moisture of the desiccant and knocks down its moisture after getting it cooled in a cooler and then it enters into the second column for drying. The cycle repeats after pre set intervals. These dryers are most ideal for larger capacities beyond 500 Nm3/hr and for the application where  dew point i(-) 40 deg C is enough. 

Specifications

• Capacity -  500 to 15,000 Nm3/hr
• Pressure -  5 to 16 Bar (g) standard . ( Higher Pressure on demand)
• Pr.Dew Point -  (-) 40 deg C

High Pressure, Low Pressure Gas Dryer

MEMBRANE DRYER

A tube is filled with hollow membranes that allow compressed air to pass but remove water vapor. These dryers give a -80 deg F dew point relative to the incoming air temperature. Membrane dryers have NO MOVING PARTS and require NO ELECTRICITY & MAINTENANCE, and therefore have a very long life. It occupies 1/10th of the space as compared to other dryers. There are many model of the membrane module which depends upon its size and capacity. A combination of many such modules enhance the capacity and dew point.

Specifications
