Customer Frequently Asked Questions (FAQ)

Q: Can the KR Series be used in applications with high inlet temperatures?

A: The standard KR Series is designed for an inlet temperature of ≤45°C. If your compressor discharge temperature is higher or the ambient conditions are severe, please choose our KRH Series, specifically designed for high-temperature conditions.

Q: Does the equipment generate a lot of condensate during operation? How is it discharged?

A: Yes, the drying process generates condensate. The KR Series comes standard with an automatic drain that periodically and automatically discharges accumulated condensate without manual intervention, ensuring continuous system operation.

Why choose the KIMAIR KR Series?

Choosing the KIMAIR KR Series means selecting a drying solution centered on reliability and economy. It does not pursue unnecessary, redundant performance but instead provides stable and effective drying protection with a reasonable investment across the widest range of industrial scenarios, maximizing your return on investment.
