21 Advantages of Using MICAFLUID Technology in 2021

Efficient degassing with the single-stage vacuum. MICAFLUII3 plants require only the smallest suction capacity from the vacuum pumps as the operating pressure for effective degassing is between 1 mbar – 9 mbar. Optimised electric heating system with horizontal configuration. The oil is indirectly heated and automatically regulated to within 1°C of the setpoint while ensuring a thermal flux of< l W / cm², which prevents hot spot cracking of the oil and guarantees its integrity. The complete system is vacuum tight. The entire system is vacuum leak-tested with a guaranteed leakage rate of< 0.025 mbar • l / s, eliminating any entry of air into the process. Variable flow-through. Due to an oil level control system, espe­cially developed by MICAFLUID, the oil flow is automatically adjusted to the flow-throughput setpoint without the risk of flooding.
