Ningbo Tenzon Umwelttechnik Co., Ltd ，High-efficiency energy-saving core processing equipment

Client Name: A Nanjing-based automotive parts company (publicly listed)

Product & Application: OMC Oil Mist Purifier; CNC machining oil mist capture and purification

Project Timeline: October 2022 – December 2022 (90 days)

Client Background & Requirements:

As a publicly listed company, this Nanjing-based automotive parts manufacturer has specialized in automotive drivetrain components for nearly 40 years. Its core products include constant velocity (CV) joints, driveshaft assemblies, wheel hub units, rubber components, and steering and suspension parts. The company’s product portfolio covers the majority of mainstream global vehicle models, and it possesses comprehensive capabilities to provide integrated driveshaft assembly solutions and direct OEM supply.

Client Requirements: The addition of numerous CNC machine tools in the machining workshop caused a steady rise in oil mist concentrations starting in August 2020, resulting in reduced visibility and poor workplace comfort. The issue was particularly acute in the grinding area, where the existing standalone oil mist treatment units performed poorly, negatively affecting employee health and well-being. Driven by a commitment to employee welfare, company leadership initiated a project to upgrade to a centralized oil mist collection system. The system was required to ensure that workplace hygiene and environmental standards met both national and corporate regulations, achieved an advanced level within the domestic industry, and complied with international occupational health and safety standards (OSHA and NIOSH).

Service Process & Why Choose Us:

Tailored to the specific conditions of the workshop and the operational characteristics of the grinding machines, the system employs low-airflow extraction when the machine doors are closed and high-airflow extraction when they are open. The centralized oil mist collection and purification system incorporates pressure sensing and automatic variable-frequency control to ensure energy efficiency and environmental compliance. Each grinding machine's oil mist branch line is equipped with an interlocked damper and a variable-airflow pneumatic valve. Emissions from the exhaust stack following purification are kept below 10 mg/m³.

Our Advantages:

• Strict adherence to relevant national and local environmental regulations and emission standards, ensuring that all parameters of the treated exhaust air meet or exceed these standards.

• Utilization of advanced, sound, proven, and reliable treatment processes that deliver significant environmental, social, and economic benefits.

• Process design and equipment selection offer substantial operational flexibility and adjustability, guaranteeing compliance with emission standards during production.

• Purification equipment designed for ease of operation, management, and maintenance, while minimizing energy consumption and operating costs.

Customer Feedback:

• High filtration and separation efficiency; long service life

• High level of automation; energy-efficient operation

• Long service life of filter elements

• Effective integration of environmental protection and production equipment; easy to operate
