Composite Super Insulation vs. Perlite
Chart's Composite SITM System VS. Competitor Perlite System
Since most liquid and gas applications require only 100-psi delivery pressure, why are ordinary tanks built with a 250-psig maximum allowable working pressure (MAWP)? The answer is simple – traditional Perlite insulation allows more heat into the liquid, driving the pressure up faster and reducing the hold time. To compensate, Perlite tanks need a 150-psi "pressure buffer" to increase the hold time and prevent unwanted, costly venting. So why pay for an outdated tradition?
At Chart, we have a great solution to those challenges: Composite Super Insulation (SI)
TM. Applying this state-of-the-art insulation technology to a lower cost 175-psig MAWP bulk tank, we build in performance and value. Even at this lower pressure, the Composite SI clearly outperforms the Perlite insulation:
- 25% Lower Cost
- 13% Smaller Footprint
- 21% Lower Tare Weight
- 60% Less Daily Evaporation
- 14 Gal/Day Lower Losses
- 5 Day Longer Hold Time
This innovative insulation system is standard on all Chart Bulk Storage Systems.
