Customer Frequently Asked Questions (FAQ)

Q: How is the strength and durability of the aluminum heat exchanger ensured?

A: The KDR Series is manufactured using high-strength aluminum alloy and a vacuum brazing process. Its structural strength has undergone rigorous calculation and testing. The pressure resistance fully complies with standards, and it offers better fatigue resistance with no corrosion risk, making it more durable than traditional copper tubes.

Q: Compared with the KR Series, where are the energy savings of the KDR specifically reflected?

A: The savings are mainly reflected in two aspects:

1. Higher heat exchange efficiency means the refrigeration compressor does less work;

2. Intelligent control reduces starts/stops and power consumption during low load conditions through hot gas bypass and thermal storage regulation. Overall, for the same air volume, the KDR Series achieves significantly lower annual power consumption.

Why choose the KDR Series?

Choosing the KIMAIR KDR Series is a future-oriented investment in energy efficiency. Through dual innovation in materials and design, it finds the optimal balance between drying performance and operating costs, delivering exceptional value returns throughout the equipment's entire lifecycle.
