KSI KTC 220 Compressed Air Refrigeration Dryer

• Drying compressed air for general industrial processes to prevent moisture damage to pneumatic tools and machinery.
• Protecting sensitive electronics and control systems from condensation within compressed air lines.
• Ensuring dry air for paint spraying and coating applications to achieve a blemish-free finish.
• Providing clean, dry air for food and beverage processing where moisture could compromise product quality or hygiene.
• Supporting pharmaceutical manufacturing by delivering dry compressed air for various production stages.

Typical capacity

For this class of equipment, flow rates commonly range from 180 to 250 m³/h (cubic metres per hour).

Power supply

Units of this type typically operate on a 230V, 50Hz, single-phase electrical supply.

Pressure dew point

A pressure dew point of +3°C is commonly achieved, indicating effective moisture removal.

Inlet air temperature

Maximum inlet air temperatures are typically around +35°C to +45°C for optimal performance.

Working pressure

Commonly designed for operating pressures up to 14 to 16 bar.

Refrigerant type

Modern units often utilise refrigerants such as R134a or R407c, though older units may vary.

• What is the primary function of a compressed air refrigeration dryer?

  Its primary function is to cool compressed air, causing water vapour to condense into liquid, which is then separated and drained, thereby reducing the dew point and preventing moisture-related issues downstream.

• Why is a low pressure dew point important?

• What maintenance is typically required for this type of dryer?

• Can this dryer be used with any compressed air system?

• What are the benefits of using a used refrigeration dryer?

Chillers and recirculating coolers hold strong reputation in laboratory and biotech sectors for temperature stability and process reliability. Buyers typically prioritise checking refrigeration system condition, pump functionality, and temperature control accuracy when purchasing used units. Industry sentiment favours models with robust construction and established service records. Common strengths include consistent cooling performance, energy efficiency relative to age, and durability when properly maintained. Verification of calibration history and cooling capacity specifications remains essential before purchase to ensure suitability for sensitive applications.
