Explosion Proof Construction for a Water Treatment Plant

Waste Water Treatment Plants have special construction requirements. Standard materials and components are inappropriate for the corrosive and volatile environments found in these applications. XeteX has experience in this specialized area, and built this unit with a stainless steel heat exchanger, spark-proof aluminum blower, externally-mounted motor, all-copper hot water coil, and aluminum mesh filters with stainless steel filter racks. The unit was also shipped with a stainless steel roof curb. This special construction allowed the facility owner to take advantage of energy recovery in a difficult environment. The result is a small load on the primary heating and cooling equipment and lower energy bills.
