Application Scenarios

- Systems equipped with air-cooled screw compressors where the aftercooler performance is inadequate.

- Hot workshops or outdoor installations where the compressor room ambient temperature exceeds 40°C.

- Processes requiring the use of high-temperature compressor discharge heat (e.g., front-end of heat recovery systems).

- Industries such as ceramics, glass, and metallurgy that generate high-temperature process gases requiring cooling and drying.

Customer Frequently Asked Questions (FAQ)

Q: Why can't a standard refrigerated air dryer handle high-temperature intake? What are the consequences of using one directly?

A: Standard refrigerated dryers (like the KR series) are typically designed for intake temperatures ≤45°C. Directly treating high-temperature air leads to:

1. Refrigeration system overload, causing frequent compressor cycling or damage;

2. A sharp rise in condensing pressure, potentially triggering the safety valve;

3. Drying failure, as the outlet dew point cannot be guaranteed. The KRH series specifically solves these issues through reinforced system design and intelligent control.

Q: Does the KRH series consume more energy than standard models?

A: While treating hot air requires more cooling capacity, the KRH series recovers energy through its efficient precooling design, resulting in an optimized operational Energy Efficiency Ratio (EER). Compared to a traditional setup of "standard dryer + front-end cooler," the integrated KRH solution is often more energy-efficient, occupies less space, and offers a more focused investment.

Why choose KIMAIR KRH Series?

When your compressed air source runs "too hot," the KRH series is the direct, efficient solution that eliminates the need to change your compressor configuration or add complex cooling facilities. It saves you from additional engineering hassles, solving high-temperature drying challenges with a single piece of equipment, ensuring system stability and reliability under extreme conditions.
