48VDC 325W/K Enclosure Heat Exchanger RS485 Communication MODBUS RTU Protocol

Heat Exchanger

The HCZA-325-000-250 heat exchanger is a passive cooling solution designed for various enclosed spaces, ensuring efficient heat dissipation for electronic equipment.

Key Features

• Passive Cooling Design: Utilizes a counterflow heat exchanger core where ambient air passes through one side of an aluminum plate and contaminated air passes on the other side. This design allows heat transfer from the contaminated air to the ambient air while keeping the air streams separate, ensuring no cross-contamination.

• High Efficiency: The heat exchanger is designed to minimize air pressure drop, allowing for more efficient cooling with the same size fan.

• Durability: Constructed with robust materials and processes, ensuring a long service life of up to 10 years.

• Energy Saving: Achieves up to 85% energy savings by recovering exhaust heat and reducing the need for additional cooling systems.

• Compliance: Meets international standards, including RoHS, CE, and ISO certifications, ensuring safety and environmental responsibility.

Applications

The HCZA-325-000-250 heat exchanger is ideal for various applications, including:

• Telecommunication Shelters: Ideal for cooling telecom cabinets and shelters, especially in outdoor environments where traditional air conditioning may not be feasible.

• Industrial Enclosures: Suitable for various industrial applications requiring efficient heat dissipation in enclosed spaces.

• Energy Storage Systems: Effective in maintaining optimal temperatures for batteries and other components in energy storage solutions.

• Data Centers: Helps in managing heat dissipation in data centers, contributing to energy efficiency and equipment reliability.
