产品介绍：

七氟丙烷是一种以化学灭火为主兼有物理灭火作用的洁净气体化学灭火剂，属于多氟代烷烃，分子式为C3HF7；它无色、无味、低毒、不导电、不污染被保护对象，不会对财物和精密设施造成损坏。

七氟丙烷能以较低的灭火浓度，可靠的扑灭B、C类火灾及电气火灾；储存空间小，临界温度高，临界压力低，在常温下可液化储存；释放后不含粒子或油状残余物，对大气臭氧层无破坏作用（ODP值为零），在大气层停留时间为31~42年，符合环保要求。

包装规格：

可循环使用钢瓶：40L、926L。

储存运输：

R227ea钢瓶为带压容器，储存时应远离火种、热源、避免阳光直接曝晒，通常储放于阴凉、干燥和通风的仓库内;搬运时应轻装、轻卸，防止钢瓶以及阀门等附件破损。

Product Introduction

Heptafluoropropane is a clean gaseous chemical fire extinguishing agent featuring dominant chemical fire-extinguishing performance combined with physical fire-extinguishing effect. It is a polyfluoroalkane with the molecular formula C₃HF₇..It is colorless, odorless, low-toxic, non-conductive, and causes no contamination to protected objects, leaving no damage to valuables and precision equipment.

With a low extinguishing concentration, R227ea can reliably put out Class B, Class C and electrical fires. It features small storage space occupation, high critical temperature and low critical pressure, enabling liquefied storage at ambient temperature. No particulate or oily residues will be generated after discharge. It has zero ODP with no damage to the atmospheric ozone layer, and its atmospheric lifetime ranges from 31 to 42 years, fully complying with environmental protection requirements.

Packaging Specifications 

Recyclable Cylinder: 40L, 926L

Storage and Transportation 

R227ea cylinders are pressure vessels. Keep them away from fire sources and heat sources, and avoid direct sunlight during storage. Store cylinders in a cool, dry and well-ventilated warehouse. Handle with care during loading and unloading to prevent damage to cylinders, valves and other accessories.
