Ichiro Genbu ICR-6005~6007 are designed to give outstanding and much extended service in a variety of applications. Ichiro Genbu ICR 6005~6007 are blended from high nature viscosity index fully synthetic base oils and fortified with a high technology core oxidation inhibitor to enhance high temperature performance and stability as well as dramatically prolong the service life span. Ichiro Genbu ICR-6005~6007 are resistant to oxidation even at very high temperature thus minimizes degradation, giving this fluid a longer usable life and minimizing deposit formation that can be inhibit efficient heat transfer. Ichiro Genbu ICR-6005~6007 may be used in both open and inert gas blanketed close heat transfer systems. And in the open system, Ichiro Genbu ICR-6005~6007 should not be used over 160 °C. While in the close system, the maximum operation temperature is 320 °C.
