Keen Compressed Gas Co. is a licensed provider of a full range of FDA qualified medical gases. Medical cylinder gases are filled and delivered locally from our plant located in Wilmington, Delaware. In addition, Bulk and MicroBulk medical gases are available as well as the all in one oxy-tote, portable oxygen system.
Carbon Dioxide is a colorless gas with a slightly pungent odor and biting taste. It will not burn, support
combustion or sustain life. It is about 1.5 times heavier than air. Normally stored as a liquid, carbon dioxide exists only as a solid or gas at room conditions. The solid CO2 snow transforms (sublimes) directly to a gas without passing through the liquid phase.
Carbon Dioxide is known in the food industry for carbonating drinks and preserving packaged foods. The non-flammable properties make it a popular pressurizing gas for aerosols.
Helium is a colorless, odorless and tasteless inert gas which has no toxic properties. A member of the rare gas chemical family, it is 1/7 as heavy as air , and is mainly sourced from natural gas wells. Liquid Helium at -452ºF is the coldest liquefied gas.
Helium has a wide range of uses including cooling superconductive magnets coils in MRI machines, pressurizing rocket rule, creating inert atmospheres for welding and heat treatment, and inflating balloons and even airbags.
Oxygen is the most abundant element on the earth’s surface and as a gas is indispensable in respiration. Composing almost 21% of the atmosphere, oxygen is a colorless, odorless and tasteless gas which supports combustion. As a liquid at -297ºF, oxygen is light blue in color and is approximately 14% heavier than water.
Nitrogen constitutes 78% of the atmosphere and is a constituent of all living tissues. Under normal conditions, nitrogen is a colorless, odorless and tasteless inert gas which has no toxic properties and is slightly lighter than air. As a liquid at -320 ºF it has a water-white appearance and must be handled with care due to its low temperature.
At room temperature, nitrous oxide is a colorless, non-flammable gas, with a lightly sweet odor and taste. It is also referred to as laughing gas, nitrous, nitro or NOS. It is an oxide of nitrogen.
Breathing air is a mixture of gaseous chemical elements and compounds used for respiration. A range of pure gases or mixtures of gases are used in breathing equipment and enclosed habitats such as scuba equipment, recompression chambers, medical life support and first aid equipment.
Keen guarantees commercial grade product delivered as a liquid meets the commercial CGA specifications. Keen does not normally guarantee commercial grade product delivered as a compressed gas meets the gaseous specification listed because gas purities are affected by normal cylinder filling practices and process procedures which may compromise the integrity of the product.
