About us — from “Boonlum Oxygen” to MUREX
A family gas business that has grown into a company serving customers through 5 branches
Where it began: Boonlum Oxygen
“Boonlum Oxygen” (บุญล้ำ ออกซิเจน) began as a family business, founded and run by the father, Mr. Srimongkol [check the spelling of the Thai first name and surname], and his family in [year founded], filling and selling oxygen to local customers. The family has always held to the same principles: safety, honesty with customers, and hands-on know-how in every step of production.
The next step: MUREX
The second generation, led by Chairman Mr. Krisana [Thai surname], turned the family business into a company by registering Murex Industrial Gas Co., Ltd. (company registration no. 0205554017035) and has worked on the business licences and safety standards required for industrial and medical gases [list the licences/standards actually held].
Today we serve hospitals, factories, and wholesale and retail customers through 5 branches: Chonburi, Sriracha–Laem Chabang, Chiang Rai, Surat Thani and Ranong. A team of engineers and maintenance technicians from head office helps keep production and safety standards the same at every branch.
Our goal
To expand our service network nationwide, with a focus on the EEC and the Northeast, and to develop high-purity gases for industries that need specialised quality.
