Tartarini™ CNF, CN, CF, and SV Series Tube Bundle Heat Exchangers
CNF, CN, CF, and SV Series heat exchangers are sized and designed to meet a large range of system requirements, and include all connections for accessories.
In the gas pressure reduction process according to the “Joule-Thomson” effect, temperature drops considerably (approximately 0.6°C / 33°F per reduction bar).This fall in gas temperature can damage the equipment due to the formation of dangerous ice crystals produced by water vapor in the gas.
