C.   • Most efficient way to reduce pressure buildup and vaporization.   • Compare utility costs, cool down, and static losses. (see charts)   • Examples for Industrial Uses of Cryogenic Liquids:     ˜ Refining ˜ Flash Freezing ˜ Aerospace Applications ˜ Superconducting Research ˜ Electronic Component Mfg ˜ CryoBio Preservation       ˜ Liquid Nitrogen Fogging for Special Effects   ˜ ESS - Environmental Stress Screening   ˜ HALT - Highly Accelerated Life Testing   ˜ HASS - Highly Accelerated Stress Screening Cryogenic Components and Accessories   • VIP VALVES - INSULATED & NON INSULATED     ˜ VIP Valves are recommended when the elimination of frost, ice, and moisture - as well as system efficiency - are essential. The return on investment is less than 1 year due to the savings it adds in controlling product quality and product loss.   • CRYOVENTS - A-MODEL & B-MODEL     ˜ CryoVents remove the vaporized gas that rises to the top of your system causing sluggish flow and pressure spurts. They are the most reliable way of maintaining liquid in VIP systems. They will not freeze open while venting gas out of the system. Requires no electricity. Does not rely on electronic probes that are pressure or temperature sensitive.   • FLEXIBLE VIP     ˜ Flexible VIP can be used selectively along with rigid VIP to minimize alignment problems, eliminate precise measurements when needed, and provide easier disassembly of sections for service or modification. Flexible VIP is less expensive than rigid VIP, but has a higher heat leak rate.   • BAYONET CONNECTIONS     ˜ These provide a mechanical connection with a leak tight shrink fit seal for sections of VIP.   • PHASE SEPARATORS     ˜ Bottom Outles, Floor Level, and Multiple Outlet ˜ Vent excess gas generated from depressurizing liquid nitrogen at the use points to provide low pressure, high quality liquid.       Please see our Cost Comparison Charts!       Top of Page
