Ningbo Tenzon Umwelttechnik Co., Ltd ，High-efficiency energy-saving core processing equipment
Wet-type dust collector system for shot blasting and sandblasting at a Nanjing-based automotive precision technology company.
Release Date：
Jun 05,2026
Client Name: A Nanjing-based automotive precision technology company
Product & Application Scenario: Automatic sludge-clearing wet dust collector; dust collection for aluminum alloy parts during sandblasting and shot blasting
Project Timeline: August 2018 – November 2018 (90 days)
Client Background and Requirements:
The company specializes in the R&D, production, and sales of key automotive components. It has developed a core product portfolio comprising automotive heat exchange components, transmission components, engine components, and new energy vehicle components, primarily serving the mid-to-high-end automotive market. To date, the company has established long-term, stable partnerships with globally renowned multinational automotive component suppliers—including Valeo, Bosch, Schaeffler, BorgWarner, Calsonic Kansei, Mahle, Magna, Siemens, Continental, and ZF—and its products are widely used in vehicle series from German, Japanese, French, and American manufacturers.
Client Requirements:
The sandblasting and shot-blasting processes for aluminum alloys generate significant amounts of dust. This not only degrades the workshop environment and compromises product quality—due to dust adhering to workpieces—but also poses substantial safety risks. Prioritizing employee health and well-being, as well as the need to boost operational efficiency and product quality, company leadership initiated a project to capture dust from the blasting equipment and upgrade to a wet, explosion-proof dust collector system. The system was required to comply with the latest national standards for explosion-proof dust collector (specifically for flammable and explosive dust), meet workplace occupational health metrics and environmental regulations (both national and local), and achieve a leading level of performance within the domestic industry.
Service Process & Why Choose Us:
To address the inefficiencies of the existing dry dust collection systems serving multiple shot-blasting and sandblasting units, we carefully analyzed the production layout, operating conditions, and the flammable/explosive nature of aluminum alloy dust. We then meticulously designed an effective wet dust collector retrofit solution. This solution utilizes wet Venturi equipment featuring automatic sludge collector to process the dust and incorporates comprehensive explosion-proof configurations.
Our Advantages:
• Automatic sludge collector; no secondary dust generation; requires near-zero maintenance.
• Non-clogging dust collector system; stable airflow and performance.
• Wet-type explosion-proof configuration; safe and reliable explosion protection.
• Modular design; compact footprint.
• High separation efficiency; consistent compliance with standards for dust collection and emission.
Customer Feedback:
• Professional and meticulous system design
• Significantly improved the workshop environment; the wet system offers peace of mind regarding safety
• Stable airflow and performance; efficient and convenient automatic sludge collector
• Easy to operate; minimal consumables and maintenance; low operating costs
