NACOL introduced Bladder Type Accumulator to Japanese market as the first domestic manufacturer in 1958.

Since then, NACOL has kept commercializing “Top disassembly/assembly type accumulators” (which allow very easy maintenances and shell inside inspections from the top opening), the seamless one piece molded bladder (a bag made of rubber), and the Pleated bladder design. These designs contributed to lengthen bladder life and the accumulator’s high performance.

NACOL has accumulated enormous know-how from its experiences as a technology-oriented industry, through its start-to-finish production. A part of this know-how has been transferred to more than 190 domestic industry property (patents and utility model patents) and more than 80 oversea patents.

Customers’ Safety First is NACOL policy and NACOL is producing Quality Assured products with stable and safe quality. NACOL obtained ISO 9001 certificate, METI Japan, ASME, CE Marking and Chinese approvals, and these represent a part of NACOL’s steadfast Quality Assurance System.
