Hi, dear customers, here we introduce the candle filter, a special industrial filter element.

General introduction

The Candle Filter is a type of pre-coat or pressure filter. The name comes from the shape of the filter element, which is a long, thin cylinder that resembles a candle. The candle filter element is mainly used in the lubricating oil filter of the BOLL filter to filter out the solid particles and colloidal substances in the working medium, and effectively control the pollution degree of the system. Our filter is replacement for brand Boll. Candles are made from wedge or v-wire and have much greater precision than older types. Most candles are mounted to the top of the filter housing, but some models have a bottom-mounted candle.

◆The filter element and the fixed plate are fixed by bolts or screwed, which is convenient for installation, disassembly and cleaning

◆High strength, long life, strong corrosion resistance, wide operating temperature range, no material detachment

◆Large filtration area, large flow rate, high porosity, good permeability, strong dirt holding capacity and strong reusability

◆Candle filter element is mainly used for oil filtration, which is composed of multiple filter elements and a magnetic filter element, with the same size and size, which effectively increases the filtration area;

Application field of candle filter

1. Thermal power and nuclear power: purification of gas turbine, boiler lubrication system, etc.

2. Purification and filtration on the ship's lubrication system.

3. Metallurgy: It is used for the filtration of the hydraulic system of rolling mills and continuous casting machines and the filtration of various lubricating equipment.

4. Petrochemical: separation and recovery of products and intermediate products in the process of oil refining and chemical production, and particle removal and filtration of oilfield well injection water and natural gas.

Case

The Candle Filter can be used for clarification of beer that has been fermented, they remain popular today. The candles are mounted inside a cylindrical pressure vessel that receives unfiltered beer. The candle itself is the septum that holds the filter aid, which could be diatomaceous earth, perlite, cellulose, or other materials, during the solid–liquid separation. Unfiltered beer passes from the outside of the candle, through the filter cake, and into the center of the candle. This now filtered beer passes up through a mounting plate or manifold holding the candles and out of the filter housing. Most candles are mounted to the top of the filter housing, but some models have a bottom-mounted candle. For the purposes of beer filtration, there is no difference in the mounting position. 

Our customer from Philippines is from Beer plant. They bought our candle filter last month. The part No. is 1365425, with 30 pcs. Now the filters have been used in their system. It is working well. We hope to repeat with our customer in future and wish their business prosper
