Our disposable cylinders are available in various formats (from 300 gr, 600 gr, 1,3 kg, 4 Kg and 10 Kg). These gases can be used in various applications such as the aquarium world, welding, systems cleaning and leak detection.[\/vc_column_text][\/vc_column][\/vc_row][vc_row type=”full_width_background” full_screen_row_position=”middle” equal_height=”yes” content_placement=”top” bg_color=”#e5e5e5″ scene_position=”center” text_color=”light” text_align=”left” top_padding=”3%” bottom_padding=”10%” overlay_strength=”0.3″ enable_shape_divider=”true” shape_divider_position=”top” shape_divider_height=”80″ bg_image_animation=”none” shape_type=”fan”][vc_column column_padding=”padding-4-percent” column_padding_position=”all” background_color=”#0060a6″ background_color_opacity=”1″ background_hover_color_opacity=”1″ column_link_target=”_self” column_shadow=”none” column_border_radius=”10px” top_margin=”4%” width=”1\/1″ tablet_width_inherit=”default” tablet_text_alignment=”default” phone_text_alignment=”default” column_border_width=”none” bg_image_animation=”none”][vc_custom_heading text=”Technical gases” font_container=”tag:h2|text_align:left|color:%23ffffff” use_theme_fonts=”yes” css=”.vc_custom_1548089951168{margin-top: 65px !important;margin-bottom: 10px !important;}” el_class=”titolomain”][vc_column_text]\n

Carbon dioxide and aquariums<\/h3>\n

Carbon dioxide (CO2) also exists as a technical gas, and is used in the world of aquariums. In fact, in aquarism, carbon dioxide is used to create an environment more favorable to the health of decorative plants (but not only). It is usually dissolved in water by micronization of bubbles, using special instruments.<\/p>\n

Nitrogen: pressurized systems<\/h3>\n

In the technical sector, nitrogen is used to put pressure on the systems (and, in some cases, to test tightness and performance). <\/span><\/p>\n

Argon: shielding gas<\/h3>\n

Argon gas is used, in the technical sector as a \u2018\u2019shielding gas\u2019\u2019. It is used to improve the process and the result of the welding and, insufflated in controlled conditions in the lance, ensures a protection from oxidation at the root of the weld.<\/p>\n

Nitrogen-hydrogen: leaf finder<\/h3>\n

Thanks to the very fine hydrogen molecule this gas is very useful for finding micro leaks in refrigeration and air conditioning circuits.<\/p>\n

Oxygen: to weld better<\/h3>\n

In the technical sector, oxygen is used in the welding process (both in the automotive world and in the industrial world) to increase the calorific value of the flame and to improve its performance. As we have seen, it is often used together with a shielding gas, such as argon.[\/vc_column_text][\/vc_column][\/vc_row]\n","protected":false},"excerpt":{"rendered":"
