HOPU brand fully automatic Double Stage Vacuum Transformer Oil Purifier delivers deep purification of transformer oil fast, reliably, and completely automatically by removing of free and soluble water, free and dissolved air and gases and other particulate matter from used transformer oil.
Tired of inefficient oil purification, costly downtime, and complex manual operations? Discover the future of transformer oil maintenance with HOPU Fully Automatic Double Stage Vacuum Transformer Oil Purifier. Engineered for unparalleled performance, reliability, and ease of use, this advanced system sets a new standard for removing water, gas, and particles from your critical transformer oil.
The Problem: Contaminated Transformer Oil
Transformer oil is the lifeblood of your equipment. Over time, it absorbs moisture and gases. It collects tiny solid particles. This contamination reduces the oil's insulating strength. It accelerates equipment aging. It can even lead to costly failures and unplanned downtime. Traditional purification methods often fall short. They can be slow, inefficient, or require constant operator attention.
Our Solution: Unmatched Efficiency & Automation
Our Double Stage Vacuum Transformer Oil Purifier tackles these problems head-on. It delivers deep purification fast, reliably, and completely automatically. Here's what makes it exceptional:
Superior Dehydration & Degassing: The Power of Dual-Stage Vacuum & Unique T-Tank Design
Advanced Vacuum System: A powerful combination of a vacuum pump and a Roots pump (vacuum booster) creates an extremely deep vacuum. This is essential for effectively removing water and dissolved gases. A clear vacuum gauge lets you monitor performance easily.
Smart Heating: Oil enters the system cold and thick. An integrated heater, precisely controlled by an automatic thermostat, warms the oil to the set temperature. Warm oil flows easier and releases water and gas much faster under vacuum.
Game-Changing T-Shaped Vacuum Tank: Forget small, traditional vertical tanks. Our innovative design adds a large horizontal chamber connected to the vertical one. This design massively increases the space inside the vacuum tank.
Inverted Atomizer: Unlike standard top-spray designs, our atomizer is uniquely positioned upside down inside the tank. As oil enters, it's transformed into a fine mist pointing downwards.
The Efficiency Advantage: This combination – the large T-tank and the inverted atomizer – forces the oil mist on a much longer journey. It travels down through the vacuum and then rises again. This dramatically increases the time the oil spends exposed to the vacuum – the key to releasing water and gas.
Result: Unbeatable Degassing Speed! With the same vacuum pump setup, our purifier removes gases and moisture 1 to 3 times faster than older top-spray vacuum purifiers. Save valuable time during maintenance windows.
Exceptional Particle Removal: Triple-Stage Filtration & Protection
Contaminated oil carries damaging solids. Our system employs three sequential filters with different levels of fineness:
A coarse filter catches larger debris first.
Medium and fine filters remove progressively smaller particles.
Smart Protection: A pressure controller constantly watches the filters. If a filter starts to clog and when pressure reaches to a set value, the system alerts you and then stop the machine automatically. This prevents damage to the filters and the machine.
Perfect Flow Control: Automatic Balance for Safe Operation
Keeping the right oil level inside the purifier is critical for safety and performance. We make it effortless:
Smart Level Sensing: High and low-level probes inside the vacuum chamber act like electronic eyes.
Automatic Balancing Of Inlet And Outlet: Based on the probe signals, two specially different sized oil inlet solenoid valves (one larger, one smaller) open and close automatically.
Result: This intelligent system perfectly balances the oil flowing in and flowing out. It prevents dangerous overfilling or running dry. You get smooth, continuous operation without manual operation.
True Fully Automatic Operation: Effortless Control
Modern problems need modern solutions. This purifier is designed for simplicity:
PLC Brain: At its core is a powerful Programmable Logic Controller (PLC). This is the machine's intelligent brain.
User-Friendly Touchscreen: A vibrant 10-inch color touchscreen provides a clear window into the machine. Operators get an intuitive interface. No complex manuals needed!
One-Touch Operation: Start the purifier with a single command. The PLC takes over, managing every step: heating, vacuum dehydration, filtration, flow balance, and safety checks.
Real-Time Monitoring: The touchscreen constantly shows vital signs: oil temperature, vacuum level, operating pressures, flow status, and filter condition. See exactly what the machine is doing at any moment.
Alarms & Safety: The system continuously checks itself. If anything unexpected happens (like low oil, high temperature, or clogged filter), it alerts the operator clearly on the screen and can safely shut down if needed.
