Qual a pressão manométrica para o gás r404a em um liofilizador que trabalha com temperatura de -60ºC?
For the R404a refrigerant at a temperature of -60ºC, the corresponding pressure is typically below its usual operational range. To find the exact value, you should consult the pressure-temperature (PT) chart specific to R404a. We currently have no such data in hand. However, remember that operating at such low temperatures might necessitate specialized equipment.
