Model 301 – 8.5 m³/hr – Acetylene Cylinder Filling Plant

The Rexarc 301 Acetylene Cylinder Filling Plant is designed for maximum carbide yield and high efficiency. The rated plant capacity is 8.5 m³ per hour using USA grade calcium carbide.

The Rexarc acetylene plant is constructed and inspected with a best practice policy that meets the intent of design principles and manufacturing practices from Section VIII of the ASME codes. It is also designed to NFPA 51A: “Standards for Acetylene Charging Plants 2006”. Equipped with all of the safety features found only in Rexarc plants, the 301 is characterized with low building and installation costs.

This acetylene plant is skid mounted with All equipment mounted on one skid.

The medium pressure generator is the highly efficient “SCREW FEED” type capable of using calcium carbide of graded size from 4 mm up to 50 mm with a maximum dust content of 15%. The recommended carbide size is 25 X 50 mm. The generator comes complete with a single 136 kg capacity hopper. Acetylene is generated only when needed.

One 20 cylinder manifold come with master valve, station flame arresters and flexible cylinder filling leads that have non-return check valves. Hand wheels with nipples that use o-rings to seal make the connection of cylinders better and faster.

A motor control center is provided to control all automated processes of the acetylene plant.
