Refrigerated Dryer

Overview

Yipu Water-Cooled Refrigerated Air Dryer leverages high-efficiency water-cooled heat exchange technology to deliver three core customer values: providing stable and reliable dry air solutions for high-temperature environments and large-capacity scenarios, reducing customers’ total lifecycle costs through energy efficiency optimization, and saving valuable space in modern workshops with its compact design. This product is particularly suitable for large manufacturing enterprises with centralized air supply systems, special industries with harsh environmental conditions, and technical renovation projects sensitive to energy consumption indicators.

I. Market Pain Point Analysis

1. Poor Adaptability to High-Temperature EnvironmentsAir-cooled refrigerated air dryers experience a sharp drop in efficiency when ambient temperature exceeds 38℃. Heat dissipation is challenging in high-temperature workshops and closed machine rooms, affecting drying performance.
2. Heat Dissipation Requirements for Large-Scale SystemsAir-cooled equipment becomes bulky when processing capacity exceeds 100 Nm³/min. High-power fans cause severe noise pollution (typically >75 dB).
3. Space Layout RestrictionsAir-cooled equipment requires sufficient ventilation clearance, occupying valuable workshop space. Thermal recirculation easily occurs when multiple units are arranged in parallel, reducing operational efficiency.
4. Demand for Energy Efficiency OptimizationCentralized air supply systems in large air compressor stations can fully utilize existing circulating water systems. Water-cooled heat exchange is 30-40% more efficient than air-cooled, facilitating energy conservation and consumption reduction.

II. System Process Flow

Four-Stage Cooling System:

1. First-Stage Pre-Cooling SectionInlet air exchanges heat with outlet cold air through an air-to-air heat exchanger, reducing temperature from 80℃ to 45℃ and recovering 25-30% of cooling capacity.
2. Second-Stage Water-Cooling SectionCooling water (20-32℃) cools the refrigerant through a shell-and-tube heat exchanger, increasing refrigerant condensation efficiency by over 35% compared to air-cooled systems.
3. Third-Stage Deep RefrigerationThe refrigerant undergoes heat and mass transfer with air in the evaporator, lowering the air temperature to a pressure dew point of 2-10℃.
4. Fourth-Stage Gas-Water SeparationTwo-stage dehydration (cyclone separation + coalescing filtration) achieves a liquid water removal rate of >97%.

Water Circulation System:

• Adopts closed-loop design with water filter and flow switch.
• Automatic water temperature control valve precisely maintains the optimal operating temperature.
• Optional plate heat exchanger for secondary heat recovery.

III. In-Depth Technical Principle Analysis

High-Efficiency Heat Exchange Mechanism:

• Evaporator features inner-threaded tubes + aluminum fins, with a heat transfer coefficient of 45 W/m²·K.
• Shell-and-tube condenser has a 20% larger heat exchange area than standard models.

IV. Core Competitive Advantages

1. Outstanding Energy Efficiency

• 18-25% more energy-efficient than air-cooled models of the same specification.
