What are the differences in functionality between a 2-bed and a 3-bed RTO?
A 2-Bed RTO reverses the process flow between the heat exchange beds to regenerate heat. A 3-Bed RTO rotates the process flow through the heat exchange beds to regenerate heat. 2-bed RTOs are susceptible to vacuum spikes and at 95% to 98% VOC destruction, a reduced efficiency relative to a 3-Bed RTO. A 3-Bed RTO avoids “puffs” by purging the off-line bed before queuing it up for the next exhaust cycle to achieve 99%+ destruction efficiency.
