Danfoss DCL 304s Hermetic Filter Drier | 1/2 in Solder ODF | 023Z4528

Product Description: The DCL 304s (023Z4528) is designed for high-tonnage systems that operate under the punishing thermal conditions of the Middle East. With a dual-action core (80% molecular sieve and 20% activated alumina), it provides 30 cubic inches of desiccant—double the capacity of standard commercial driers. In the UAE—where high condensing temperatures frequently lead to refrigerant breakdown—the activated alumina component is vital for neutralizing harmful acids and preventing compressor burnout. The copper-plated steel connectors allow UAE technicians to perform fast, high-quality brazing on 1/2-inch liquid lines while maintaining the mechanical strength of a steel shell, ensuring a leak-proof seal that stands up to the heavy vibrations of large chiller plants and industrial rooftop units.

Key Features & Benefits:

• Maximum Adsorption Reserve: The 30 cu.in. core offers a massive surface area for capturing moisture and acids, extending service intervals in humid UAE coastal regions.
• Superior Acid Protection: Specifically formulated to protect expensive industrial compressors from chemical corrosion in high-heat environments like Dubai and Abu Dhabi.
• Copper-Plated Connectors: Facilitates a high-integrity brazed joint, providing a more reliable, vibration-resistant connection than mechanical flare fittings.
• 46 Bar Working Pressure: Fully compatible with high-pressure R410A, R32, and other high-pressure refrigerants common in modern UAE HVAC infrastructure.
• Built-in 25 $\mu$m Filter: Protects expansion valves and sensitive components from solid contaminants and debris.

FAQs:

• Q: When is it necessary to use a 30 cu.in. drier like the 304s in the UAE?
• A: It is recommended for large-capacity systems (over 5-10 tons) or systems where high humidity and temperature make extra protection essential for compressor longevity.
• Q: Is this drier compatible with POE oil and R410A?
• A: Yes, the DCL series is optimized for use with HFC refrigerants and POE/PAG oils used in the UAE’s latest cooling equipment.
• Q: Does it include a sight glass?
• A: No, but it is highly recommended to install a Danfoss SG sight glass downstream of this drier to monitor the system’s moisture level.
