The Core Filtration Unit

Model LY-50 Plate Pressure Oil Purifier
This is a classic Chinese industrial plate-and-frame oil filter press. It uses a series of internal plates layered with industrial filter paper to remove fine solid contaminants, carbon residues, and free water from the oil before or after it goes into the impregnation tank.
Specifications: The "LY-50" model indicates a rated flow rate of 50 Liters per minute (3,000 L/H) and typically operates via a 1.1 kW motor at 1400 r/min

The Vacuum Dehydration / Degassing Module

Components: dedicated control panel, a multi-stage condensation/cooling column and a rotary vane vacuum pump at the base.
Function: This module acts as a high-vacuum purifier. It pulls a deep vacuum to boil off dissolved moisture and gases from the oil under low temperatures, ensuring the insulating oil achieves ultra-high dielectric strength.

The Impregnation Chambers

Vertical Cylindrical Vessel
Horizontal Rectangular Autoclave: This heavy-duty chamber with a multi-spoke locking wheel door is the main vacuum impregnation chamber. Stators, coils, or transformers are placed inside this chamber. The system draws air out of the components, then transfers the clean, purified oil from the LY-50 filtration loop directly into the chamber to saturate the deep insulation layers.

The LY series is predominantly manufactured by industrial vacuum and oil purification specialists in Chongqing, China. They are typically custom-built into complete VPI (Vacuum Pressure Impregnation) packages tailored to the layout of the processing workshop.

Used in x-ray high voltage tank manufacturing in Littleton, MA for approximately 5 years. It worked well.
