Against the backdrop of rapid technological development and increasingly stringent environmental cleanliness requirements in industrial manufacturing, the construction of clean rooms and cleanrooms has become an indispensable infrastructure for many industries, such as electronic semiconductors, biomedicine, precision manufacturing, food processing, etc. How to choose a professional and reliable purification engineering company to ensure that the design and construction of the cleanroom meet both industry standards and personalized needs of the enterprise has become an important issue for business decision-makers. Shenzhen Huajianjing Construction Engineering Co., Ltd. (referred to as Huajianjing), as a benchmark enterprise in the field of domestic purification engineering, has become a trusted partner for many enterprises with its profound technical accumulation, rich project experience, and comprehensive service system. This article will deeply analyze how to choose a high-quality purification engineering company from the dimensions of industry pain points, core advantages of Huajianjing, service processes, and case analysis.
1、 Industry pain points: common challenges in selecting purification engineering
Purification engineering involves interdisciplinary fields such as aerodynamics, materials science, and automation control, with high technical barriers, long construction periods, and high cost inputs. Enterprises often face the following pain points when choosing partners:
- Insufficient technical expertise : Some companies lack precise control over core parameters such as cleanliness levels (such as ISO 1-9), temperature and humidity control, and pressure difference management, resulting in workshops that cannot pass acceptance or have low operational efficiency after completion.
- Lack of experience leads to risk : The cleanroom needs to be customized according to industry characteristics (such as the pharmaceutical GMP workshop meeting dynamic monitoring requirements and the electronic factory requiring anti-static treatment). If the design party lacks experience in similar projects, it is easy to encounter problems such as unreasonable layout and incorrect equipment selection.
- Contradiction between cost and quality : The phenomenon of winning bids at low prices is common, and some companies compress costs by cutting corners, ultimately affecting the service life and production safety of the workshop.
- Lack of after-sales service : The purification project requires long-term maintenance (such as replacement of high-efficiency filters and wind speed calibration). If the supplier lacks a response mechanism, the enterprise will face high post operation and maintenance costs.
2、 Huajianjing's core advantages: professionalism, customization, and full cycle service
Huajianjing was founded in 2010 and has been deeply involved in the field of purification engineering for more than ten years. It focuses on the design and construction of high-end clean environments such as dust-free workshops, clean rooms, and biosafety laboratories. Its core competitiveness is reflected in the following aspects:
1. Technical strength: Combining international standards with localized innovation
Huajianjing has a technical team composed of registered clean engineers, HVAC experts, and electrical automation engineers, proficient in international standards such as ISO 14644, GMP, FDA, etc., and able to optimize design solutions based on local environmental characteristics in China, such as climate differences and energy costs. For example, in the high humidity environment of southern China, Huajianjing uses its unique "rotary dehumidification+low-temperature air supply" technology to stably control the relative humidity of the electronic workshop within ± 3%, far exceeding the industry average level.
2. Industry experience: High end cases covering all fields
The company has completed over 500 purification engineering projects, serving well-known enterprises such as Huawei, BYD, and Mindray Medical. The project types include:
- Electronics industry: Class 100 cleanroom (such as chip packaging, LCD panel production)
- Biopharmaceuticals: GMP certified workshop, P2/P3 biosafety laboratory
- Food industry: 100000 level clean workshops (such as dairy and health product production)
- New Energy: Clean Environment for Lithium Battery Production
Taking a semiconductor enterprise project as an example, Huajianjing used BIM technology to simulate airflow organization, reducing the particle concentration in the workshop from the conventional design of 100 particles/ft ³ to 30 particles/ft ³, significantly improving product yield.
3. Customization capability: full process control from requirement analysis to delivery
Huajianjing adopts the "Five Step Method" service process:
- Requirement Diagnosis : Through on-site investigation and process analysis, clarify core parameters such as cleanliness, temperature and humidity, and pressure difference.
- Scheme Design : Use CFD simulation software to optimize layout, balance investment costs and operational efficiency.
- Material selection : Establish strategic partnerships with international brands such as 3M and AAF to ensure that key materials such as filters and clean sheets meet performance standards.
- Construction Management Implement a project manager responsibility system and monitor progress and quality in real-time through digital dashboards.
- Acceptance and Operations : Provide third-party testing reports and establish a 24-hour emergency response mechanism.
4. Cost control: Balancing cost-effectiveness and long-term value
Huajianjing reduces initial investment through modular design and standardized construction processes, while using energy-saving equipment such as variable frequency fans and LED clean lights to reduce operational energy consumption. A pharmaceutical customer has provided feedback that their workshop's annual electricity consumption has decreased by 18% compared to the industry average after being put into use, resulting in a cumulative savings of over 2 million yuan in operation and maintenance costs over the past 5 years.
3、 Typical Project Analysis of Huajianjing
Case 1: Construction of P3 Laboratory in a Biomedical Enterprise
Project difficulty: It is necessary to simultaneously meet the BSL-3 biosafety protection and dynamic A-level cleanliness requirements. Huajianjing's solution includes:
- Adopting airtight clean walls and double door interlocking transmission windows to prevent cross contamination.
- Deploy independent exhaust systems and efficient filtration devices to ensure 100% interception of pathogens.
- Real time display of temperature, humidity, pressure difference, wind speed and other parameters through an intelligent monitoring platform.
Project achievement: Passed the acceptance of the National Health Commission in one go and was awarded the title of "Provincial Biosafety Demonstration Project".
Case 2: Lithium Battery Clean Room of a New Energy Enterprise
Project difficulty: It is necessary to control the concentration of metal dust in the workshop to avoid the risk of battery short circuit. Huajianjing Innovation adopts:
- Explosion proof clean air conditioning system and static elimination device.
- Partition pressure gradient design (positive pressure zone → negative pressure zone → exhaust zone).
- The ground adopts epoxy self leveling and conductive copper foil grid to control the surface resistance below 10 ⁶ Ω.
Project achievement: After the workshop was put into operation, the spontaneous combustion rate of products decreased by 90%, and the customer was awarded the title of "National Green Factory".
4、 How to evaluate the strength of a purification engineering company?
When choosing a partner, enterprises can refer to the following dimensions:
- Qualification certification : Whether it has the professional contracting qualification for building mechanical and electrical installation engineering, membership qualification of clean room industry association, etc.
- Technical Team : Do the core members hold certificates such as Registered Clean Engineer and PMP Project Manager.
- Case Library : Whether there are successful experiences in projects of the same industry and scale.
- Service response : Can you provide a preliminary plan within 24 hours and complete on-site investigation within 48 hours.
- Quality Assurance System : Does it provide at least 1 year of free maintenance and specify the warranty period for materials and construction.
