Dryer Iran

refrigeration dryer

Refrigerated air dryers utilize a closed refrigeration circuit with R134a or R410a refrigerant. Their nominal capacity ranges from 10 to 5000 liters per second under standard conditions. The pressure dew point at the outlet is set at a constant 3±°C at 7 bar pressure. Energy efficiency is rated between 0.8 to 1.2 kW per 100 liters per second. Condensers and evaporators are copper tube and aluminum fin coils with 14 fins per inch. Screw or scroll compressors with IE4 motors and IP55 protection ensure reliable operation. A digital PID controller manages evaporator temperature with 0.5°C accuracy.

The dryer structure includes a cyclone separator with 99% efficiency for bulk moisture removal. Air-to-air heat exchangers with 85% efficiency reduce the systems thermal load. Activated carbon filters adsorb particles down to 0.01 microns in size. Modular solenoid valves with under 2-second response enable precise flow control. The housing is constructed from galvanized sheet steel with an 80-micron epoxy coating. Operating sound pressure level is maintained below 65 dB at one meter. An intelligent alarm system monitors filter differential pressure and abnormal temperatures. Optimal performance is typically within an ambient temperature range of 5 to 45°C.

A refrigerated dryer reduces moisture in compressed air by cooling it close to its dew point. These systems typically deliver a constant pressure dew point in the range of +3°C to +10°C. Their nominal flow capacity varies from 50 to 50,000 liters per second. A refrigeration circuit with a compressor, evaporator, condenser, and expansion valve forms the units core. Modern refrigerants like R-410A or R-134A are selected per environmental regulations. The designed pressure drop across the dryer is usually below 0.2 bar. These units reduce the relative humidity of the output air to below 35%.

The dryer structure consists of aluminum or steel heat exchangers with finned designs. A cyclonic separator removes condensed water droplets with 99% efficiency. An electronic PID control system regulates temperature and pressure within ±1°C accuracy. For harsh conditions, dual-circuit models with air-cooled and water-cooled condensers are available. The specific energy consumption of new dryers has reached about 0.5 kW per 100 l/s. This equipment is essential to prevent corrosion and freezing in industrial compressed air lines. Periodic maintenance includes servicing filters and refrigerant recharge per the manufacturers schedule.

The rotary dryer is constructed from 316 stainless steel with 8 to 20 mm shell thickness. Cylinder diameter ranges from 1 to 4 meters with lengths of 5 to 25 meters. Rotation speed is 3 to 15 RPM via VFD inverter control. Inlet air temperature ranges from 150 to 600°C with ±2°C control accuracy. Final product moisture content can reach as low as 0.5%. Indirect heat transfer systems achieve thermal efficiency over 85%. Specific energy consumption is 800 to 1200 kcal per kilogram of evaporated water.

The internal structure features 45 to 60-degree angled steel lifters. These lifters increase material retention time up to 30 minutes. Rock wool insulation with 150 mm thickness keeps heat loss below 3%. The air circulation system uses centrifugal fans with 50,000 m³/hour capacity. Cyclonic filters provide 99.8% separation efficiency for particles above 10 microns. A PLC control unit integrates 50 temperature and pressure monitoring points. This dryer can process 500 to 20,000 kilograms of input material per hour.

Refrigerated dryers are designed for standard capacities of 10 to 500 cubic feet per minute CFM. Their pressure dew point reaches 3± degrees Celsius at 7 bar working pressure. Screw compressors with 3 to 100 kW power consume 400V three-phase electrical current. The specific energy consumption SEC of advanced models reaches 0.2 kW per CFM. The moisture separator tank is constructed from epoxy-coated carbon steel. This tank withstands working pressures up to 16 bar.

The main structure comprises three separate circuits: refrigeration, air, and control. Heat exchangers are made from pure copper with a 40 W/m·K heat transfer coefficient. Canopy filters operate with 99.9% efficiency against 0.01-micron particles. The energy recovery system recovers up to 25% of waste heat. Dew point sensors monitor parameters with ±1 degree Celsius accuracy. Solenoid valves with a response time under 100 milliseconds operate the system.
