Q We are contemplating installing a fluid mixer in a zone 0 area. Will an ISO-MIX system meet the ATEX requirements?
A Yes.
The ISO–MIX fluid mixing system consists of a pump, a recirculation loop and an ISO–MIX rotary jet head (RJH) installed under the liquid surface of the tank where the mixing is taking place. The ingredients to be mixed into the bulk volume are introduced into the recirculation loop on the suction side of the recirculation pump. The liquid is recirculated through the nozzles of the ISO–MIX RJH, which slowly rotate around two axes, driven by a turbine propelled by the recirculating liquid.
An important element in the fulfilment of the ATEX directive is the fact that the RJH, when in the mixing mode, remains submerged and will only rotate when liquid is pumped through the mixer.
The only component that possibly needs to be ATEX-approved is the pump if this is positioned in the zone 0 area.
In explosion zone 0 areas, using an ISO-MIX RJH for fluid mixing offers a faster and more energy-efficient mixing system. The ISO-MIX system is ATEX approved while being a much more cost-effective solution than traditional systems using propellers for agitation.
The unique ISO-MIX RJH mixing systems was recently installed at several vodka and cognac production plants. Before, it might take up to 4 hours of mixing, before the in-mixing of just 250 liters of 96% alcohol in a batch of 30,000 liters was completed. With the ISO-MIX system, the in-mixing is completed in less than 10 minutes.
The substantially reduced mixing time, naturally, is an important advantage to the manufacturer. Equally important is the fact, that the ISO-MIX system is ATEX-approved, and the initial costs of the system are considerably lower than with a traditional mixing system.
