Hose/Tube for Water (Cooling Water)
(a) PVC Pressure Hose for Industrial Purposes (Non-Drinking Use)
Generally, hoses are used as applications for transporting water (such as water sprinkling hose and shower hose). However, if you use an inexpensive vinyl hose for a continuous use under harsh conditions, it may be possible to leak, tear, or deteriorate in a short period of time. A pressure-resistant hose, developed for industrial and industrial use, is highly recommended for plant and industrial machinery (such as for chiller).
In this application, we recommend E-TB: PRESSURE HOSE. This is a PVC braided, soft hose that stands for long duration with RoHS 2 compliant certificate. Maximum working pressure (up to I.D. 25mm) at 20$^\circ$C is 1 MPa (10 bar). E-TB can be used up to 60$^\circ$C.
(b) Non-PVC Hose/Tube (For Industrial and Food Grade Purposes)
Some customers prefer non-PVC hose/tube even for transferring water. This is because PVC hose/tube contains plasticizer (source of elution materials), which flows out with the fluid. That is to say, the fluid is "contaminated" after passing through PVC hose/tube. If you prevent the fluid from being contaminated, our recommendation is non-PVC hose/tube.
In order to deal with this request, we have E-KYT: KT TUBE and E-KYS: KY SUNFOODS HOSE. Both E-KYT and E-KYS conform to the Food Sanitation Law No. 370 (No.370 of the Ministry of Health and Welfare for Food Sanitation) (Conformity to N-Heptane) and Positive List System (PL System).
