Heat of Compression Air Dryer

Heated from the inside Heat is created in non-lubricated air compressors, which is lost owing to cooling in the after cooler. This heat is used to heat the air for regeneration in the Heat of Compression HOC Air Dryer. Hot compressed air is fed via a heater in this dryer to maintain a temperature of roughly 180 degrees Celsius before being pushed through the desiccant bed for regeneration. This air is cooled in an after cooler, where moisture is collected and drained away in a moisture separator, after the moisture has been removed. The cooled air is then sent through the desiccant tower for drying.

The following is a list of notable features: -There will be no purging losses. -Electrical Heater Load Savings -It is simple to produce a dew point of (-) 600C in the atmosphere. -From 400 CFM onwards, the most cost-effective.

Externally Heated Dryer

Externally Heated Dryers are built with a outside vessel to indirectly heat the wet absorbent. Externally purge air is supplied to the dryer with the help of external blower. Unheated purge air is required to flow through bed in order to provide cooling effect

The following is a list of notable features: -40°F dew point performance -Ambient Air Temperature: 38°F – 125°F -Inlet Air Temperature: 40°F – 110°F -Operating Pressure: 60 to 150 psig

Internally Heated Dryer

Internally heated dryer is an adapted form of heatless drier with extremely minimal purge air loss due to regeneration by dry air at low pressure and high temperature. Heaters are used to heat the purge air to roughly 180 degrees Celsius, which improves its moisture carrying capacity. This hot purge air is pushed through the desiccant bed at low pressure to regenerate with a tiny amount of purge.

The following is a list of notable features: -Purge air loss is reduced. -It is possible to obtain a dew point of (-) 80 degrees Celsius (atm). -Design that is compact -Operation is simple. -The most cost-effective range is between 200 and 1000 CFM. -Desiccant Dryer Advanced Version with Reduced Purge Air Loss

Heatless Dryer

The simplest of all desiccant-based air dryers is the Heatless Air Dryer. Two desiccant towers are employed in this dryer. While one tower is drying, the second tower is undergoing regeneration. A portion of the dry air from the in-line tower is used to regenerate the second tower. A sequence controller mounted in the control panel controls tower changeover every 5 minutes.

The following is a list of notable features: -Operation is simple. -Simple to keep up with -Purge Saver Microprocessor-based Controller -There is no need for a heater or a cooler. -It is simple to achieve a dew point of (-) 40 to (-) 60 degrees Celsius in the atmosphere.

Bio Gas Dryer

Air-N-Gas Process Technologies has developed systems to condition anaerobic digested methane for use in microturbines or combustion engines, as well as water vapor to protect gas compressors and remove water vapor from low-BTU gas to fulfil contract standards. Our refrigerated landfill/digester gas dryer was created particularly for this use. It’s a great way to get rid of hazardous water vapor and increase the combustibility of landfill gas and biogas, especially when the incoming gas temperature is between 40 and 45 degrees Celsius. Patented dew point sensor and flood level control, stainless steel heat exchanger tubes and moisture separator, and modular design for ease of maintenance are among the product’s characteristics. Air-N-Gas Process Technologies has long been a pioneer in the fields of absorbent desiccant, gas dehydration, and filtration. Please contact us right away if you have any inquiries or to place an order. Features and Advantages: -All wetted components are made of stainless steel. -Dew point of 3°C -Free of CFC refrigerant -Base is made of structural solid steel. Application: -Dehydration of landfill gas -Dehydration of the digestive system’s gases -Plants that cleanse wastewater -Wineries and breweries -Plants that make cheese

Refrigerator Air Dryer

Reducing the temperature is the easiest approach to remove moisture from compressed air. Compressed air is passed through a heat interchanger in a Refrigerated Air Dryer, and cold refrigerant at roughly 3 degrees Celsius is fed through the other side of the heat interchanger. Most of the moisture condenses at this temperature, which is subsequently separated and drained off in a moisture separator. The following is a list of notable features: -Non-cyclic procedure that is simple. -Operating costs are low. -Noise Reduction -Purge Loss: 0 -It is possible to dry even lubricated air. -Any capacity is possible. -PDP of 3 degrees Celsius -Electronic Command and Control -Refrigerant that is good for the environment

Split Flow no Purge Loss Dryer

Part of the wet air is pumped via a heater to increase its moisture carrying capacity, which is utilised for regeneration, reducing purge loss. The entering moist air is separated in a distributor in this sort of drier. 60-70 percent of wet air is used for drying, while 30-40 percent is circulated via a heater, which raises the temperature of the air, removing moisture from the desiccant bed, and then cooling it in an after cooler, where moisture is condensed and drained out in a moisture separator. This air is returned to the distributor and mixed with incoming air before being disseminated once more.

The following is a list of notable features: -There will be no purging losses.  -There is no need for a blower.  -There is no usage of external air, thus there is no possibility of contamination. -From 400 CFM onwards, the most cost-effective.

Blower Purge Regenerative Dryer

The regeneration air in a Blower Purge Regenerative Dryer comes from a blower that is heated in a heating chamber, enhancing its moisture carrying capacity. For regeneration, this heated air is routed through the desiccant bed. The following is a list of notable features: -For large capacities, low operating costs are important. -It is possible to reach a dew point of (-) 60 degrees Celsius. -From 1000 CFM onwards, the most cost-effective. Limitations: -For regeneration, heat energy is required. -It is cost effective for High Flow Only because of the high capital cost.
