PRECAST CONCRETE ELEMENTSwww.cpi-worldwide.com CPI %u2013 Concrete Plant International %u2013 4 | 2025The Solution %u2013 Air CirculationConsidering the existing curing system was relatively modern, Kraft worked to retain as much of the old system as possible, reducing cost for the customer and overall installation time. Firstly, the supply ducting design was changed. The multilevel hot air outlet system inside the chamber was modified by blocking off the outlets, and removing the end section of the duct. Additional ducting and a 90-degree bend was added to the now open end, to channel the supply air flow along floor level to the front of the chamber. This meant that the hot air flow was now delivered laterally at floor level, along the full length of the production pallet. This allows the warm air to gently rise to the upper parts of the chamber for recirculation, without direct airflow across the product. The airflow, now over the full-chamber depth, drastically improves the consistency of the climate. Special adapter pieces were supplied to facilitate connection of the main ducts to the new Kraft Convect-Air%u00ae unit. In conjunction with the ducting activities, some maintenance and improvement works were carried out on the curing chamber itself. The old breakthrough points for the ducting were patched with insulating material and sealed. All curing chamber flashings were removed to allow sealing of the sandwich panel connections with expanding foam. The aim was to remove thermal bridges from the chamber, reducing heat loss and preventing condensation. With the curing chamber now planned to operate at much higher relative humidity level than ever before, it was essential that any leakages to the insulating envelope were abated. Meticulous planning and coordination with the customer ensured that the complete mechanical and electrical installation was completed on schedule, and just before the Christmas break. Commissioning was planned for early 2024 following completion of the power and water supply work. The Solution %u2013 Humidity Addition SystemCuring concrete products within dry conditions can result in surface cracking, brittle edges and corners and other unwanted product defects. To minimise these potential issues Kraft supplied the AutoFog%u2122 moisture addition system. The AutoFog is The 100kg/hour AutoFog moisture addition system introduces steam directly into the air circulation supply ducting, increasing the relative humidity in the curing chamber whenever required.www.mbk-kisslegg.de mbk Maschinenbau GmbHDSM - Cobot welding machines OMNIA - loT platformDAVE - Service platformNEWS
