HC-A-EX in Action: Reliable Weighing for ATEX Zone 2

In production areas where flammable materials and oxygen come together, every precaution must be taken to eliminate ignition sources. To minimize risks, the ATEX directive (Directive 2014/34/EU) provides a clear framework for safety in potentially explosive atmospheres. The HC-A-EX is built in full compliance with these requirements, ensuring reliable operation and protection for people, processes, and products.

The checkweigher is specifically designed for ATEX Zone 2, where explosive gas or dust atmospheres may occasionally occur. Its protective features include nickel-coated conveyor belts for conductivity and an over-pressure encapsulated control cabinet to prevent the ingress of flammable gases. These design elements guarantee optimal explosion protection while maintaining full production capability.

Despite operating under ATEX conditions, the HC-A-EX achieves throughputs of more than 300 products per minute. At its core lies the EC-FS-EX weighing cell, certified to the Ex II 3 D Ex tc IIIB T100 °C Dc protection class. Housed in stainless steel, it provides a weighing range of up to 15 kg with a sampling rate of 1 ms—ensuring top accuracy even at high speeds.

Like all checkweighers in the HC-A series, the HC-A-EX benefits from a modular system design. This flexibility allows it to be adapted to a wide range of applications and easily integrated into existing production lines. From pharmaceuticals to chemicals to aerosol filling, the system delivers precise weight control under the strictest safety standards.

Modern production environments demand more than just compliance. With real-time monitoring via Comscale dashboards, predictive maintenance to reduce downtime, and the option of hybrid configurations (e.g., weighing combined with metal detection or vision inspection), the HC-A-EX is prepared for the next level of intelligent manufacturing.

• ATEX Zone 2 conformity – guaranteed safe operation in explosive environments
• High-speed weighing – up to 15 kg range at 1 ms sampling
• Ultra-high throughput – exceeding 300 pieces per minute
• Flexible modular design – easy integration into complex production lines
• Future-ready – intelligent monitoring and hybrid inspection options

The HC-A-EX demonstrates that uncompromising safety and blistering efficiency can go hand in hand. With certified ATEX protection, high-speed precision, and intelligent connectivity, it is the ideal solution for industries such as aerosol manufacturing, chemicals, and pharmaceuticals—where safety and performance must always be guaranteed.
