The above Cryogenic Pump Efficiency Calculator is for general, estimating purposes only. EIC Cryo does not guarantee or claim to achieve specific performance criteria from the use of this calculator, as it does not account for any number of potential operational or environmental variables. The purpose of this tool is to provide a quick efficiency calculator for typical, submersible cryogenic pump conditions.
