Cold Storage Panel Production Line
Our cold storage production line introduces the advanced equipment and technology from Italy OMS, the double crawler is up to 36 meters long. This provides sufficient ripening reaction time for polyurethane foaming, which greatly improves the bonding and molding performance of the panels.
The equipment can produce 250mm ultra-thick cold storage panels to meet the special requirements of customers for low-temperature environments. The advanced polyurethane pentane foaming process eliminates the original F11 and 141B blowing agent, which not only has better foaming but also truly realizes zero fluoride emissions in the production process.
