How we started
● Since 1995, Calstar®, an entrepreneurial team was set up to develop environmental protection equipment. Also, to distribute solvent recovery equipment from other countries.
●In 2003, "TAIWAN KUANBAO ENVIRONMENTAL DEVELOPMENT COMPANY" was set up. In the meantime, patents and trade mark of solvent recovery equipment is accomplished.
●We worked with CNOOC to build a membrane treatment solvent recovery system in 2012. In 2013, the eighth generation of automated explosion-proof containers was successfully developed by the Kuanbao team.
●In 2017, Kuanbao team served the industry for more than 30 years, professional explosion-proof solvent recovery machine development, product sales worldwide. And we passed 20 Chinese explosion-proof certificates for 4 times, and IS09001 and ISO14001 certifications for 5 times.
●In 2019, the Kuanbao team developed an online VOC gas recovery equipment, and the exhaust gas met the environmental protection testing standards.
●In 2021, the Kuanbao team developed a solvent dehydration equipment with a purity of 99.9%.
