DongAn Group Solution for the Food and Pharmaceutical Industry

【Background】

In the food and pharmaceutical industry, electrical control enclosures serve as the core control units for production equipment, purification systems and testing facilities. Their cleanliness, corrosion resistance, anti-contamination performance and regulatory compliance directly affect product quality, production environment compliance rate and industry certification pass rate.

Adopting purified design, food-grade material selection and GMP-compliant configuration, DongAn Group electrical control enclosures are widely applied in food processing, pharmaceutical production, medical device manufacturing and other scenarios. Covering automated production line control, cleanroom environment regulation, and sterile testing equipment control, the products deliver outstanding clean protection, corrosion and disinfection resistance, and full regulatory compliance. They meet the stringent production management requirements of the food and pharmaceutical sector and have gained the trust of many well-known enterprises.

【Case Introduction】

Application of Clean-Type Control Enclosures in Sterile Pharmaceutical Production Lines

When constructing a sterile pharmaceutical production line, a large pharmaceutical enterprise set strict requirements on the cleanliness, corrosion resistance and compliance of control enclosures. The production workshop requires frequent disinfection with VHP vaporized hydrogen peroxide and ozone, while featuring liquid residue and high humidity. Conventional control enclosures are prone to dust accumulation and corrosion with poor sealing performance, easily causing environmental contamination and electrical component failures. They fail to meet the GMP Good Manufacturing Practice standards, thereby affecting product quality and industry certification.

Solutions and Core Advantages of DongAn Group Electrical Control Enclosures 

1、High Cleanliness and Anti-Contamination Design

The enclosure adopts a fully sealed seamless structure with a smooth, dead-angle-free surface that resists dust accumulation, complying with Grade A/B/C/D cleanroom standards. Food-grade disinfection-resistant sealing strips are fitted at door gaps with an embedded installation design to avoid dust deposition and microbial growth. The enclosures withstand high-frequency disinfection and eliminate the risk of cross-contamination to the production environment. A condensate-prevention structure on the enclosure top prevents condensed water dripping from contaminating pharmaceuticals and production equipment, fully meeting GMP cleanliness control requirements.

2、Corrosion and Disinfection Resistant Material Selection

The enclosure is made of 304 stainless steel with brushed and polished surface treatment, offering superior corrosion resistance suitable for high-cleanliness and high-frequency disinfection scenarios in the food and pharmaceutical industry. Compared with ordinary stainless steel enclosures, its corrosion resistance is improved by over 80%, with a service life extended by 5–8 years.

3、Compliant and Intelligent Configuration

The control enclosure is equipped with intelligent temperature and humidity regulation modules to maintain optimal internal ambient conditions and prevent component moisture and aging. Internal wiring adopts a dual-trunking layered design with physical isolation of strong and weak current to reduce electromagnetic interference. The neat layout and clear marking facilitate maintenance and certification inspections, fully satisfying industry compliance standards.

Application Effect

After adopting DongAn Group clean-type control enclosures on the sterile pharmaceutical production line, the facility fully complies with GMP certification standards. The compliance rate of production environment cleanliness has reached 100%, the failure rate of electrical components has decreased by 70%, and damage to enclosures caused by disinfection operations is nearly zero. The solution greatly reduces equipment maintenance costs and product contamination risks. The customer highly recognizes the product’s excellent performance in cleanliness, corrosion resistance and regulatory compliance.
