Features: 1. Use of special metal materials which is compatible with fire-resistant oil, combined with technologies of vacuum dewatering, multi-stage filtration system and new adsorbent 2. Stainless steel machine body, pipes and filtering components, reliable, anti-corrosion, durable. 3. Duplex-stereo film evaporation technology, equips with unique and advanced dewatering, degassing components, can rapidly and effectively remove water, gas, particles and volatile matter 4. Advanced medium cooling system 5. High quality filtering components, large capacity for holding particles, anti-corrosion, good mechanical performance, long lifetime. 6. Efficient electric heating system, heating uniformity, less power consumption, safe, and reliable. 7. Adopt interlocked protective system, which connect oil pump, heater and liquid level sensor, avoiding blank heating, blank pumping, oil leak and electricity leak. If there is any fault, machine will be power off automatically.
