Proper selection ensures air free from moisture, oil, dust, and contaminants, maintaining system efficiency and reliability.

Refrigerated Air Dryers - Functionality and Features

ATS refrigerated dryers cool compressed air through a multi-stage process involving pre-cooling via an air/air heat exchanger, further cooling in an evaporator, condensate separation by a demister, and refrigerant regulation via a by-pass pressure valve. Features include low pressure drop, ultra-compact aluminum heat exchangers, easy maintenance, oversized components for reliability, and user-friendly control panels for monitoring dew point, operating modes, drain management, and alarms.

Heat Exchanger Design

• Air/Air Exchanger: Pre-cools inlet air and post-heats outlet air to reduce energy consumption and prevent condensate formation.
• Flow Mixing Chamber: Ensures uniform air temperature entering the evaporator for optimal efficiency.
• Evaporator: Further cools air and separates condensate while maintaining low pressure drop.

• User interface includes a panel with manual test key.
• Available connection sizes: 1/2", 3/8", and 3/4".
• Supports pressures and capacities ranging from 3.6 to 3600 m³/min.

Gold Series ECA 6 After-Cooler

• High-efficiency aluminum cooler combined with electric fan, achieving a 5°C temperature drop from ambient.
• Condensate discharged via high-efficiency condenser separator.
• Available in multiple voltage options and connection types, with configurations without separator, motor, or frame.
• Models range from ECA 78 to ECA 3700, covering flow rates from 78 to 3700 m³/h, connection sizes from 3/4" to 3", and weights from 9 to 180 kg.

Operational Parameters and Standards

Performance testing follows ISO 7183 and ISO 8573-1 standards, with standard reference conditions including ambient temperature of 35°C, inlet air pressure of 7 bar, and dew point classes depending on series. Correction factors for ambient temperature and pressure variations are provided to adjust performance expectations. Maximum working conditions are detailed in product datasheets.

Energy Saving Features

Energy efficiency is a key focus, especially in the Platinum Series with inverter technology enabling variable speed operation and energy accumulation functions. Gold Series adsorption dryers use microprocessor controls and hygrometric sensors to optimize purge rates and cycle times based on real-time dew point measurements.

Recommendations and Maintenance

• Users should consult technical or sales departments for special requirements or availability.
• Regular maintenance, including replacement of filter elements and separator bags, is critical to maintain performance and comply with environmental standards.
• Correction factors for flow rates and dew point adjustments ensure proper sizing and operation under varying conditions.
