Overview
The ZLA-02 is a compact 120 NL/min thermoelectric compressed air dryer for laboratory instruments, pneumatic controls and small OEM equipment. Its refrigerant-free solid-state cooling delivers point-of-use moisture control from a 290 × 140 × 260 mm enclosure, making it the lowest-flow model in the ZLA range.

7. Air Outlet
Dry air outlet connection.
Installation Requirements
Proper installation is essential to ensure optimal performance and long-term reliability of the thermoelectric air dryer.
– Install the unit in a well-ventilated area with at least 100 mm clearance on both sides.
– Keep the dryer away from heat sources and ensure sufficient airflow around the cooling assembly.
– Place the unit on a stable and level surface.
– Ensure the inlet air temperature does not exceed 35–40°C for optimal performance.
– Connect to a 220V AC power supply and ensure proper grounding.
– Check all air connections for leaks before operation.
– The system typically reaches stable dew point after approximately 15–20 minutes of operation.
Applications
This thermoelectric compressed air dryer is suitable for a wide range of compressed air systems, including:
– Laboratory air supply systems
– Automation and control equipment
– Small workshop compressed air setups
– Instrument air systems
– Light industrial applications
Typical compressed air system configuration
Air Compressor → Pre-filter → Thermoelectric Air Dryer (ZLA-02) → Fine Filter → End Application
For applications requiring ultra-low dew point (≤ -40°C), a desiccant air dryer can be added downstream to achieve higher air quality.

Frequently Asked Questions
Is the ZLA-02 a refrigerant-free air dryer?
Yes. The ZLA-02 uses solid-state thermoelectric cooling rather than a refrigeration compressor and refrigerant circuit.
What is the rated flow of the ZLA-02?
The rated flow is 120 NL/min, with a maximum working pressure of 8 bar.
Can the ZLA-02 be integrated into OEM equipment?
Yes. The ZLA-02 suits laboratory instruments, pneumatic controls and small OEM machinery requiring up to 120 NL/min. Its G1/4 connections and narrow enclosure support installation inside compact equipment or close to the point of use.
When should I use a desiccant dryer instead?
Use a heatless desiccant dryer when the application requires a pressure dew point around -40°C.
