The MGW-1 process mixer is designed for preparing alcohol,
alcohol-based or water-based solutions, storing them, and maintaining
the temperature of the medium at the level necessary for further
processing.
The device is made to ATEX standard and can operate zone classified as
explosion-hazard zone standard Z1 and Z2.
The mixer is designed as a vertical cylindrical tank with a working
capacity of 1000L and an internal diameter of 1100mm, ellipsoidal
bottom. The tank is a welded, double-shell structure made of 316L
stainless steel (components in contact with the product) and 304
(components not in contact with the product). The device is equipped
with a pressurized heating jacket placed on the tank sidewall,
enabling heating or maintaining the product temperature. Water with a
permissible pressure of 0.1 MPa will be used as the medium in the
heating space.
50 mm thick Irpur E 33 polyurethane foam was used to insulate the
mixer.
