　　Project Category: Pharmaceutical Cold Storage, Laboratory Cold Storage, Biological Cold Storage, Pharmaceutical Cold Storage

　　Project Period: 60 Days

　　Year of Cooperation: 2020

　　Acceptance Date: June 2020

　　Project Requirements: Nanjing Green Leaf Pharmaceuticals -20℃ Pharmaceutical Explosion-proof Freezer Design and Installation New Project, undertaken and constructed by our company Haoshuang Refrigeration, plans to build a -20℃℃ pharmaceutical explosion-proof freezer for the storage of intermediates in the production process of egg yolk lecithin (for injection) in the auxiliary material workshop 1 (Pharmaceutical Valley) of the auxiliary material building of Pharmaceutical Valley I-2.

　　Project Overview:

　　(1) According to customer requirements, the pharmaceutical explosion-proof freezer is located in the soaking room of the auxiliary material workshop 1 (Pharmaceutical Valley), and the outdoor unit of the freezer is placed on the roof. The pharmaceutical explosion-proof freezer is installed in a designated clean workshop that meets GMP requirements.

　　(2) Our company Haoshuang Refrigeration designs, builds, operates, maintains or verifies the cold storage in accordance with the relevant requirements of China GMP and FDA and CGMP for the entire project.

　　(3) The cold storage installation of this project adopts Changzhou Jingxue 0.8mm outer/0.6mm inner stainless steel 150mm thick polyurethane (PU) insulation board, B1 grade flame retardant, anti-condensation treatment of the ground, explosion-proof self-limiting heating wire, and 5mm cement mortar leveling.

　　(4) According to the customer’s temperature requirements, the storage temperature in the pharmaceutical explosion-proof freezer can be controlled between -20℃~-28℃ and the temperature distribution is uniform. The difference between the measuring points in various parts of the freezer does not exceed 5℃. Therefore, our company’s refrigeration equipment uses 2 German Bitzer compressor hot fluorine defrosting type box-type piston refrigeration units, 2 hot fluorine defrosting type cold air blowers from Italy LU-VE (stainless steel shell, motor explosion-proof, chassis explosion-proof heating film), and the refrigeration equipment adopts two systems, one for use and one for backup.

　　(5) The pharmaceutical explosion-proof freezer project was completed in 2020, fully meeting the original planned standard requirements of GSP/GMP generation and operation standards, and successfully passed the final acceptance inspection. It has been commissioned and delivered to the customer for normal use, and has been accepted by Party A at one time.
