Machinery & Equipment Co. offers used holoflites, also known as thermal screw processors, designed for indirect heating and cooling of bulk solids in applications such as drying, cooling, reacting, and sludge processing. These systems utilize hollow flight screws to transfer heat efficiently while gently conveying material, making them well suited for chemical, mineral, food, and environmental applications. Inventory may include single and dual screw configurations, as well as thermal screw dryers, thermal screw coolers, and indirect heat exchangers for solids handling. Equipment from recognized manufacturers such as Metso Denver, Bethlehem, Joy, and Rietz is commonly available, along with Bepex, Andritz, Komline-Sanderson, and Thermal Processing Solutions. Machinery & Equipment Co. can help match the right unit based on throughput, heat transfer requirements, and material characteristics, including access to incoming and off-market equipment.
