Description

XeteX designs and manufactures custom air handling units to meet the needs of each application. This project features a custom heat recovery unit for a Waste Water Treatment Plant.

A key feature of this unit is the explosion-proof design to support potential hazards of the operating environment. Another important aspect is selecting non-corrosive materials to preserve performance in harsh conditions.
