Gas Introduction

Heptafluoropropane (HFC-227ea/FM200) is a clean gas fire extinguishing agent that mainly uses chemical fire extinguishing and also has physical fire extinguishing effects; It is colorless, odorless, low toxic, non-conductive, non polluting to the protected object, and will not cause damage to property and precision facilities; Can reliably extinguish Class B and C fires as well as electrical fires with a lower extinguishing concentration; Small storage space, high critical temperature, low critical pressure, and can be liquefied and stored at room temperature; After release, it does not contain particles or oily residues, has no destructive effect on the atmospheric ozone layer (ODP value is zero), and has a residence time in the atmosphere of 31-42 years, which meets environmental protection requirements.
