ATEX Fans and EX Fans
The NOVENCO® ATEX and EX fans are for installation and operation in hazardous environments with high requirements for safety within land, marine and offshore ventilation systems. The fans are compact, robust and well-suited for operation in the harsh and unhealthy conditions of, for example, industrial and process ventilation. The performance characteristics and qualities are identical to the standard versions of the fans.
The design and technologies of the ATEX and EX fans include the strong and durable NOVENCO® NovAxTM and ZerAx® axial fans as well as the range of extremely robust centrifugal fans. Both the NovAx and ZerAx fan ranges offer fan efficiencies well above the alternatives in the market and being fitted with frequency converters the total efficiencies are best-in-class.
The range of sizes and capacities cover low to medium pressure systems for removal and transport of high volumes of flammable and dusty air in industrial environments.
