Atlas Copco TCD2013-L04
Product Introduction:
The TCD2013-L04 is a refrigerated compressed air dryer from Atlas Copco’s TCD product line. It cools compressed air to approximately +3°C pressure dew point, removing the majority of moisture from the air stream. The “2013” denotes the model series with a nominal air flow capacity of approximately 20 m³/min (700 CFM). The “L04” is the configuration code specifying electrical and control options. This is a standalone dryer — not a compressor.

Material Composition:
- Air-to-Air Heat Exchanger: Aluminum plate-fin (evaporator and condenser)
- Refrigerant Circuit: Copper tubing, hermetically sealed compressor (for non-cycling variant) or capillary tube (cycling variant)
- Separator: Stainless steel mesh demister pad
- Cabinet: Powder-coated carbon steel (RAL 5010 or 7035)
- Drain Valve: Brass or stainless steel solenoid valve
Structural Features:
- Compact upright cabinet design
- Front-access service panels for filter and drain maintenance
- Pre-filter (coalescing) installed on air inlet
- After-filter (activated carbon) optional for oil vapor removal
- Digital controller with dew point monitoring (on premium variants)
Working Principle:
Hot compressed air enters the dryer and passes through an air-to-air heat exchanger (pre-cooler) where it is cooled by the outgoing cold air. The pre-cooled air then enters the evaporator where it is cooled further to approximately +3°C by the refrigerant circuit. Moisture condenses out and is removed via the automatic drain. The cold air then passes back through the pre-cooler, recovering cold energy and warming the outgoing air to near ambient temperature (prevents external condensation on downstream pipes).
Key Advantages:
- +3°C dew point — removes approximately 80% of moisture from compressed air
- Energy-efficient heat recovery design (outgoing air pre-cools incoming air)
- Low maintenance — no consumables other than filters
- Automatic condensate drain — no manual drain required
- Compact footprint for 700 CFM capacity
Applicable Industries:
All compressed air systems requiring dry air: manufacturing, food & beverage, painting, pneumatic tools, general industry.
Installation Requirements:
- Install after the compressor and before the receiver tank (recommended)
- Ambient: 2°C to +45°C (refrigerant performance degrades below 2°C)
- Minimum 0.5 m clearance on all sides for airflow
- Electrical: 400V/50Hz/3-phase, 16A breaker
- Inlet/outlet piping: minimum DN40 (1½”) connections
Usage Notes:
- Pre-filter replacement: every 4,000 hours or 1 year
- After-filter (if fitted): every 8,000 hours
- Clean condenser coils quarterly in dusty environments
- Do not install in unheated spaces below 2°C — risk of evaporator freeze-up
- This dryer is rated for 16 bar max inlet — do not connect to TC54S (50 bar) without a pressure-reducing valve
