Description

KOOLTRONIC Water-to-Air Heat Exchangers provide uniform cooling in a closed-loop system where a reliable source of clean, cool water is available. The KNHE Series was designed primarily for use in harsh environments with cooling requirements in excess of the capabilities of air-to-air heat exchangers or air conditioners. They are particularly useful in highly contaminated environments that would require very frequent cleaning or changing of ambient air filters, or require frequent cleaning of the heat exchanger core. KOOLTRONIC KNHE NEMA 4/4X Water-to-Air Heat Exchangers can furnish greater cooling capacities than air-to-air models, depending on water temperature and rate of flow. Ambient air is sealed out; heat transfer surfaces remain clean.
The higher cooling capacity of the KNHE Series depends on the temperature of the cooling water. Thus, if the water is cold enough, the temperature of the air delivered to the electronics cabinet can actually be lower than that provided by air conditioners, at less cost. This unit combines the best features of the NEMA 4/4X heat exchangers with the increased cooling capacity offered by the water-to-air models. These units provide a compact size and ease of mounting with the exclusive KOOLTRONIC M/TAB mounting system.

KOOLTRONIC also designs and manufactures a variety of air conditioners to meet unique specifications. We invite your inquiries about our modification and custom-design capabilities.
