Aircel RTM Series

Aircel RTM Series

$0.00
High-Capacity Cycling Refrigerated Air Dryer 38°F Dew Point (5,000 - 30,000 scfm)

The Aircel RTM Series (2,500 - 30,000 scfm) utilizes high efficiency compressors with defined loading and unloading capacities and a thermal mass medium for energy storage. The refrigeration system cools the thermal mass medium to a predetermined lower temperature. Once that temperature is reached, the system goes into standby mode until the temperature rises to another predetermined set point. Only then does the system come out of standby mode and once again cools the thermal mass medium. No energy is wasted when demand on the dryer is low. The RTM dryers are ideally suited when large air volumes need to be dried to a reliable and constant dew point.

• 38°F - 50°F Dew Point
• Ambient Air Temperature 35°F - 120°F
• Maximum Inlet Air Temperature 140°F
• Maximum Operating Pressure: 150 psig
• 1 Year Standard Limited Warranty

How to Size a RTM

 

To Size the Dryer Capacity for Actual Conditions

Adjusted Capacity = scfm x C1 x C2 x C3 x C4

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: RTM-6000
Standard Capacity: 6000 scfm
Actual Operating Conditions: 90°F ambient temperature: C1 = 1.05
100°F inlet temperature: C2 = 1.0
125 psig system pressure: C3 = 1.07
38°F required dew point: C4 = 1.0
Adjusted Capacity = 6000 scfm x 1.05 x 1.0 x 1.07 x 1.0 = 6,741 scfm

 

To Select the Dryer Model for Actual Conditions

Adjusted Capacity = scfm/C1/C2/C3/C4

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: 5000 scfm
Actual Operating Conditions: 80°F ambient temperature: C1 = 1.07
90°F inlet temperature: C2 = 1.21
100 psig system pressure: C3 = 1.0
Required dew point : 38°F pdp: C4 = 1.0
Adjusted Capacity = 5000 scfm / 1.07 / 1.21 / 1.0 / 1.0 = 3,861 scfm

Selected Dryer Model: RTM-4000

 

Capacity Correction Factors

The Compressed Air and Gas Institute (CAGI)has developed standards to protect users of compressed air & gas equipment. ADF100 the current standard for refrigerated compressed air dryers, specifies the dryers performance to be rated at 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 ambient air temperatures (C1), inlet air temperatures (C2), system pressures (C3), and varying dew point requirements (C4).

Overview

The Aircel RTM Series (2,500 - 30,000 scfm) utilizes high efficiency compressors with defined loading and unloading capacities and a thermal mass medium for energy storage. The refrigeration system cools the thermal mass medium to a predetermined lower temperature. Once that temperature is reached, the system goes into standby mode until the temperature rises to another predetermined set point. Only then does the system come out of standby mode and once again cools the thermal mass medium. No energy is wasted when demand on the dryer is low. The RTM dryers are ideally suited when large air volumes need to be dried to a reliable and constant dew point.

All Aircel dryers are designed to give our customers the best value available in the industry - reliable performance meeting industry standards while consuming the lowest amount of energy possible. An Aircel high-capacity air dryer will always pay for itself by reducing air distribution system costs, lengthening tool life, reducing maintenance downtime and system damage.

How it Works

How the RTM Series Works

1. Hot saturated air from the aftercooler enters the air/air heat exchanger, where the air is pre-cooled by the cold dry air leaving the heat exchanger.

2. The pre-cooled air then enters the air/glycol heat exchanger, where is it cooled to its final dew point by chilled water/glycol, flowing in the counter-current through the shell.

3. The chilled air passes through the moisture separator, which has a high efficiency of separation at varying flow rates. Condensate is removed from the system without any loss of air via a zero purge drain valve.

4. Finally the cold, dry air is reheated in the air/air heat exchanger by the incoming hot air for maximum volumetric efficiency before exiting the dryer. The water/glycol is chilled by a cycling refrigeration system, and continuously pumped through the shell side of the air/glycol heat exchanger. The glycol flow rate remains constant, regardless of compressed air load. The refrigeration compressor unloads, and/or cycles OFF, when a pre-set water/glycol temperature is reached, thus minimizing electrical power consumption.

Components

Compressor

As an industry leader in compressed air drying technology, Aircel uses high efficiency scroll compressors, semi-hermetic compressors, and rotary screws for all high-capacity dryers providing extra reliability and more energy savings.

Heat Exchangers

Aircels high thermal efficiency stainless steel plant heat exchanger and ASME-stamped shell and tubetype pre-cooler/reheater and air-to-water/glycol heat exchangers are designed for low pressure drop and maximum performance.

Separator

High efficiency centrifugal separators and integrated stainless steel separators eliminate moisture from the air system. The unique design of the separator removes 99% of the water droplets with no mechanical movement and maintenance.

Condensers

Aircels high-capacity dryers are built standard with air-cooled (2500-5000 scfm) or water-cooled (6000 and up scfm) condenser and automatic water regulating valve (remote air-cooled condenser option).

Demand-Activated, Zero-Purge Condensate Drain

One of the important components of the dryer is the discharge of the condensate, which has been removed from the compressed air supply. Aircels zero-purge drain system automatically discharges contaminated condensate from compressed air systems.

Centrifugal Pump

High efficiency close-coupled centrifugal pump with back flow preventer and no flow shutdown provides reliable performance.
