Delivering Energy Efficient & Purge Reduction Control

Aircel AHLD E ControllerThe Aircel Programmable Controller (APC) and Energy Management System (EMS) is standard on the AHLD. This energy-saving demand cycle reduces purge air and optimizes dryer performance by monitoring the moisture fast and early in the middle portion of the tower desiccant bed. This control panel automatically adjusts the regeneration cycle maintaining dew point and extending the drying cycle. Switching is less frequent, reducing dryer maintenance and fully utilizing desiccant capacity. This addition will improve reliability and performance while sustaining a constant dew point. The end result is an overall purge reduction and significant energy savings.

How It Works

How The AHLD E-Series Works

Moisture saturated compressed air enters the coalescing pre filter (F1) where aerosols are coalesced then drained via an automatic drain system. The moist water vapor-laden inlet air free of liquid water flows to the inlet of the dryer through the APV (Automatic Piston Valve) (V1) which diverts the inlet air to one of the towers, in this example tower (T1). Air flows upward through the adsorbent bed removing the moisture vapor, the dried airflow exits the tower through the outlet APV valve (V2) flowing to the outlet particulate after filter (F2) which removes particulates from the air stream. Clean and dry air now flows to the process air distribution system.

As one tower is drying air, the other tower will be regenerating (purging) the adsorbent bed. In this example, tower (T2) will be regenerating. Prior to regeneration, the exhaust valve (V4) is opened and the tower is depressurized to near atmospheric pressure, the tower will now be regenerating. During the regenerating process a small portion of dry outlet compressed air is used, 15% on average. The dry regeneration airflow is channeled through the outlet APV valve to the regenerating tower (T2) removing moisture from the adsorbent bed and exits the regenerating tower (T2) through exhaust valve (V4) and exhaust muffler to ambient. After regeneration cycle is complete, valve (V4) closes causing tower (T2) to repressurize to line pressure.

Next, the towers will switch when exhaust valve (V3) opens causing tower (T1) to depressurize and regenerate, simultaneously the inlet and outlet APV valves (V1) and (V2) will shift the pistons to the low pressure tower (T1) causing the inlet airflow to be diverted to tower (T2) which will now be the drying tower. This switching process will continue repeatedly.

The dryer control system is completely automatic and cycles the system through the drying and regeneration cycles. The standard cycle drying time is 5 minutes, regeneration cycle is 4 minutes, and repressurizing cycle is 1 minute.

Dryer Sizing Tool

Use our Drying Sizing Tool by clicking the button or you can manually find the dryer you need based on your system specifications using the formulas below.

How to Size a AHLD E-Series

 

To Size the Dryer Capacity for Actual Conditions

Adjusted Capacity = scfm x C1 x C2

To calculate the capacity of a given dryer based on non-standard operating conditions, multiply the standard capacity by the appropriate correction factor(s).

EXAMPLE: Dryer Model: AHLD-100 E
Standard Capacity: 100 scfm
Actual Operating Conditions: 120 psig system pressure: C1 = 1.18
100°F ambient temperature: C2 = 1.0
Adjusted Capacity = 100 scfm x 1.18 x 1.0 = 118 scfm

 

To Select the Dryer Model for Actual Conditions

Adjusted Capacity = scfm/C1/C2

To choose a dryer based on a given flow at non-standard operating conditions, divide the given flow by the appropriate correction factor(s).

EXAMPLE: Given Flow: 350 scfm
Actual Operating Conditions: 120 psig system pressure: C1 = 1.18
100°F ambient temperature: C2 = 1.0
Adjusted Capacity = 350 scfm / 1.18 / 1.0 = 296.6 scfm

Selected Dryer Model: AHLD-300 E

 

Capacity Correction Factors

The Compressed Air and Gas Institute (CAGI) has developed standards to protect users of compressed air & gas equipment ADF 200 is the current standard for desiccant compressed air dryers. ADF 200 specifies the dryers performance to be rated at -40°F pressure dew point, 100°F inlet temperature, 100°F ambient temperature, and 100 psig system pressure. To adjust the dryer capacity from these "CAGI conditions" to your specific application, please use the correction factors below for differing system pressures (C1) and inlet air temperatures (C2).

Capacity correction factors for system air pressure (C1)
System Pressure (psig) 60 70 80 90 100 110 120 130 140 150
Correction Factor 0.65 0.73 0.82 0.91 1 1.09 1.18 1.27 1.35 1.44

 

Capacity correction factors for inlet air temperature (C2)
Ambient Temperature (°F) 70 80 90 100 105* 110* 115* 120*
Correction Factor 1.2 1.15 1.10 1 0.9 0.8 0.7 0.6

*For inlet temperature above 100°F, molecular sieve desiccant is required.
