About the PR750H Pelletizer

​

The PR750H Pelletizer from Cold Jet presents a state-of-the-art dry ice Pelletizer with features for easy operation, swift production shifts, and high capacity performance.

​

The PR750H produces high-quality dry ice pellets. This is secured by the closed chamber technology which also ensures fast production shifts and an extremely short start-up time.

​

The automatic change of extruder plates eliminates downtime and reduces the loss of valuable CO2. The pellet length and quality are optimized by the PR750 design, and it can produce two sizes of pellets without changing the extruder plates. The PR750H has many technical features compared to existing products on the market.

​

The hydraulic unit uses logic controlled high-performance components for optimal output.

​

The machine parts are protected by a moisture-free enclosure, which also reduces the noise level to a minimum (below 75 dB(a). The PR750H provides a non-stop supply of high-density dry ice pellets. The source of raw material for the production of pellets is liquid carbon dioxide preserved at low temperatures in a storage tank.

​

The control system of the PR750H Pelletizer, based on Beckhoff Industrial PC and HMI system, offers maximum functionality and a user-friendly interface. By selecting the pellet size required, production is started by pressing one button. Just-In- Time production minimizes labor and waste during production.
