“Blue Arctic” Series 2520 transfer hose by Unisource Manufacturing, Inc. is manufactured specifically for the demanding requirements of CO2 liquid and vapor transfer. “Blue Arctic” outperforms other types of hose that have traditionally been used in connection to tanks and trailers. Unlike rubber hydraulic hose that is constructed with carbon steel reinforcing, “Blue Arctic” is reinforced with stainless steel braids to resist carbonic acid—the result of CO2 and moisture combination. In addition, our pricked cover solves the problem of bubbling that the covers of hydraulic hoses have experienced. “Blue Arctic” hose will be dramatically more flexible in CO2 transfer than standard rubber hoses due to a specially blended tube rated to minus 65°F. The two-braid construction also offers much better kink resistance than comparable single braid products.
“Blue Arctic” transfer hose is also superior to flexible metal hoses in liquid CO2 transfer. Stainless steel hose is heavier and more difficult to flex than our rubber/wire combination. In addition, the corrugations inside stainless steel hose can trap frozen CO2, leading to plugging of the hose and/or surrounding equipment during product transfer. Ice slugs could also be a potential safety hazard during hose clean-out of the stainless steel type hose. “Blue Arctic” eliminates this possibility by use of a smooth rubber tube design.
“Blue Arctic” hose is factory assembled in custom lengths of up to 100 feet. Special heavy-duty brass bar-stock female NPT end fittings are attached by use of high-pressure aluminum crimp collars that interlock with the brass fittings. Assemblies are rated for 450 PSIG maximum working pressure and each one is pressure tested to 675 PSIG. Hose is black in color with a blue Myar longitudinal stripe. Branding includes manufacturer, working pressure rating, service, and date of manufacture. Fittings are stamped with date codes. “Blue Arctic” meets the requirements of CGA G-6.6, Standard for Elastomer-Type Carbon Dioxide Bulk Transfer Hose.
