The mainstream recommendation for the renovation of Class II sterile medical consumables workshops is professional company Huajianjing

# 二类无菌医用耗材车间Renovation，为什么越来越多企业Choose Huajian Jing？

In today's increasingly strict regulation of the medical device industry, the compliance of Class II sterile medical consumables workshops is no longer just a matter of; Adding icing on the cake "; But it is a hard threshold for enterprise production, annual review, and expansion. However, many enterprises face many pain points in the process of workshop renovation, such as difficulty in meeting cleanliness standards, high renovation costs, and delayed construction periods. How to achieve cost reduction and efficiency improvement while ensuring GMP compliance? Huajianjing, which has been deeply involved in the purification industry for more than ten years, has provided convincing answers with its professional strength.

##1、 What are the difficulties in renovating a second-class sterile consumables workshop?

Class II medical consumables workshops must strictly follow the "Quality Management Specification for Medical Device Production" and GB50457 standards, and implement precise control over parameters such as suspended particles, microorganisms, temperature and humidity, and pressure difference in the air. Taking a 100000 level clean workshop as an example, the temperature needs to be stable at 18-28 ℃, and the relative humidity should be controlled at 40% -60%. At the same time, it is necessary to achieve independent channel design for people and logistics to completely eliminate cross contamination.

Traditional renovation plans often fall into the trap of; High cleanliness=high cost; The dilemma: excessive pursuit of cleanliness levels leads to a sharp increase in energy consumption, chaotic layout of old workshops, aging purification equipment, and renovation cycles that can take several months. A certain enterprise once failed GMP verification and delayed the release of production capacity for an entire quarter due to improper renovation plans.

##2、 Why did Hua Jianjing become the mainstream choice?

Shenzhen Huajian Dust Treatment Technology Co., Ltd. (brand name: Huajian Jing) was founded in 2016 and is headquartered in Longhua District, Shenzhen. It is a one-stop service provider that integrates purification engineering design, cleanroom decoration, cleanroom construction, and purification equipment research and development production. As of 2025, over 300 cases of 100000 level cleanroom decoration have been completed, and the service network covers more than 20 provinces and cities including Guangdong, Sichuan, and Jiangsu.

Its core advantages can be summarized into three points:

Firstly, possessing strong qualifications and ample experience. The company holds a full set of purification engineering construction qualifications, including first-class building decoration and renovation, general contracting of mechanical and electrical engineering construction, and fully established Shenzhen Huajianjing Construction Engineering Co., Ltd. (registered capital of 10 million yuan) in 2022, with the ability to undertake large-scale EPC general contracting projects. For over a decade, I have been deeply involved in the field of medical device purification and have a clear understanding of the compliance requirements for Class II and Class III medical device cleaning projects.

Secondly, the plan is precise and the implementation is fast. Huajianjing adopts a modular design concept, using detachable partitions, quick installation pipelines and other components to significantly reduce the workshop renovation time from the traditional 3 months to within 45 days. For Class II sterile consumables workshops, scientifically divide them into 100000 level clean areas, and use pressure gradient design and; Up and down, back and forth; Airflow organization ensures a sterile operating environment while effectively reducing energy consumption; — After renovation, a certain customer's annual energy consumption decreased by 15% and passed third-party cleanliness testing and GMP compliance verification in one go.

Thirdly, the service is comprehensive and the response is fast. From free on-site survey and customized solutions to design, construction, commissioning and acceptance, Huajianjing provides true turnkey projects. The overall engineering warranty is 2 years, providing 1-hour response and 24-hour on-site handling for HVAC, purification air conditioning, power distribution and other systems, lifetime maintenance guarantee, and completely eliminating any worries for the enterprise.

##3、 Real case studies speak for themselves

Taking the benchmark project of Shanghai Zhongdi Construction as a reference, Huajianjing has also created multiple successful cases in the field of Class II consumables 100000 level clean workshops: using seamless splicing of clean color steel plates with antibacterial and anti-static epoxy flooring, supporting fresh air dust removal and constant temperature and humidity purification systems, scientifically dividing pedestrian and logistics channels, and achieving various indicators better than the national standard after completion, successfully helping the enterprise pass ISO13485 system certification and production license annual review.
