Tailor-made for Jiangsu Dena Chemical

As a professional laboratory contractor, we understand that every project carries the innovative expectations of the enterprise. The Jiangsu Dena Chemical Co., Ltd. R&D laboratory project, constructed by Nanjing Expansion Technology Co., Ltd. Jiangsu Dena Chemical Co., Ltd. R&D Laboratory Project is based on a deep understanding of the core needs of enterprise users—maximizing functionality at a lower cost while also considering display value.

This laboratory is not a simple stacking of space, but a solution that precisely matches the needs of the enterprise.

Core functional areas are stable and online: As the core research and development sites, negative pressure laboratories and physical and chemical laboratories adhere to professional standards, ensuring that every detail, from the ventilation system to the experimental table configuration, meets the needs of high-precision experiments, safeguarding research efficiency.

Office and display area is just right: The office area, meeting area, reception desk, and exhibition area, while meeting the needs of daily office collaboration, incorporate the ingenuity of display-type space design. This ensures efficient team communication and allows visiting customers to intuitively feel the company's R&D strength, making the laboratory a "talking" brand name card.

Auxiliary functional areas are safe and worry-free: Auxiliary spaces such as reagent storage areas, hazardous chemical reagent storage areas, gas cylinder rooms, and explosion-proof rooms are based on safety and compliance, using practical configurations to optimize costs, meeting basic functions without redundant investment.

We fully understand the enterprise users' concern for "cost control" and "function maximization" In the scheme design, we precisely focus on core needs: experimental functions must meet standards, and the attributes of visits and demonstrations are fully considered, while non-core links use standardized configurations to ensure basic efficiency. This approach of "spending money where it matters" allows the laboratory to undertake R&D tasks while demonstrating advantages with high cost-effectiveness.

From functional implementation to cost control, from research needs to visitor experience, we always provide customized solutions from the perspective of the enterprise. The R&D laboratory solution for Jiangsu Dena Chemical is a specific practice of our "cost-effectiveness" and "practicality," and we hope it can provide strong support for the company's innovation journey.

Various thorny problems are always encountered in laboratory construction. Faced with a series of existing problems in the Jiangsu Dena Chemical laboratory project, we have developed practical solutions based on professional technology and innovative thinking.

Limitations of the original building on site
Ingenious solutions to solve problems

The original building presented many challenges to the project. On the one hand, the location of the exhaust pipe shaft in the original building is fixed, and the exhaust equipment and risers are reused. Not only is the exhaust volume fixed, but the operating noise is also extremely high, with initial on-site measurements reaching around 90dB, which greatly affects the normal operation of the laboratory and the comfort of personnel.

To address this issue, we adopted a dual noise reduction scheme:

A silencer and static pressure box was added to the outlet of the pipe shaft to effectively reduce noise transmission.

At the same time, another layer of sound insulation treatment was added to the outside of the static pressure box to further block noise, creating a quiet environment for the laboratory.

On the other hand, this building has cantilever structures on all sides from the fifth floor, and this project is located on the fifth floor, resulting in many shear walls and building structural columns around, which makes space planning inconvenient.

We cleverly utilized this feature, dividing the space into small areas according to the layout of the shear walls, which are used as auxiliary functional areas such as reagent and hazardous chemical reagent storage, gas cylinder rooms, explosion-proof rooms, and storage rooms, making full use of the space while meeting the various functional needs of the laboratory.

Chemical Synthesis Three Rooms
Strictly prevent the spread of foul odors

Chemical synthesis three rooms will conduct chemical experiments that produce foul-smelling gases. If not handled properly, the spread of odors will affect the entire laboratory environment.

We have taken a series of strict measures:

HVAC uses a fresh air system to ensure continuous renewal of indoor air.

The existing exhaust equipment is independently planned to serve the chemical synthesis three rooms to ensure that foul odors can be specifically treated.

The room is designed as a negative pressure laboratory to prevent odor leakage using pressure difference.

The maintenance structure uses color-coated steel plates to ensure airtightness, and the door uses medical airtight doors to further enhance the isolation effect.

III. Exhaust and Energy Consumption: Balancing Needs and Energy Saving

Laboratories have high exhaust requirements, which means that foreseeable operating energy consumption will be high. Balancing exhaust requirements and energy saving is key.

Our solutions are as follows:

Self-compensating ventilation cabinets are used to improve exhaust efficiency while reducing energy consumption.

The HVAC system uses personnel fresh air + multi-unit system, and uses variable frequency equipment to adjust the operating power according to actual needs, effectively reducing energy consumption.

Through these innovative technical solutions, we successfully overcame various challenges in the Jiangsu Dena Chemical Laboratory project, providing strong support for the safe, efficient, and environmentally friendly operation of the laboratory. In the future, we will continue to uphold our professional spirit and provide high-quality laboratory construction solutions for more projects.
