Magvent Air and Dirt Separator Demountable MAGCVAD-R

Air Magnetite Sludge and Dirt Removal from Heating / Chilled Water Systems

Air Magnetite Sludge and Dirt in heating and chilled water systems can be the cause of major problems such as pump failure, corrosion and energy loss.

The Magvent (MAGCAVD-R) is used to remove Air Magnetite Sludge and Dirt. Installed on the flow pipe in the system the Magvent (MAGCAVD-R) will eliminate air and all types of dirt particles from heating and chilled water systems.

Introduction

Magvent
The Clean Solution
An Air Dirt and Magnetite free water system.

Problems arising with Air Dirt and Magnetite in water systems

Deaeration

The word Deaeration describes the removal of dissolved gases from liquids such as air from water. When water is heated or the pressure reduced gas microbubbles are released into the system. Microbubbles can be the cause of major of problems such as pump failure, corrosion and energy loss.

Dirt and Magnetite

Magnetite, Dirt and Sludge can be the cause of major problems such as pump failure, corrosion and energy loss in Heating & Chilled Water Systems.

The Solution

The Magvent combines the removal of Air, Magnetite, Dirt and Sludge . Installed on the flow pipe in the system the Magvent (MAGCVAD-R) will eliminate these microbubbles and all types of Magnetite, Dirt and Sludge from heating and chilled water systems down to 5 micron and less.

Features

• High-gauss magnetic rod installed to remove all magnetite in the water system.
  Greatly reduced commissioning times after initial fill.
  
• Longer system life (Due to Air, Magnetite & Dirt elimination)
• Low-pressure drop
• Bi-directional flow
• Max.temp. 110 c
• Max. Working pressure 14 bar
• Tested to 21 bar
• Standard carbon steel shell (stainless on request)
• Air collects in the air chamber before being automatically vented.
  
• Floating dirt can be removed by opening the valve situated on the side of the unit.
• The same valve is used for releasing air when filling the system
• Large collector ensures that flushing is only required periodically
• Dirt & Sludge can be flushed while fully operational (no need to shut down)
• An internal stainless steel concentrator to aid removal of air, microbubbles & dirt.

Magvent (MAGCVAD-R) location Click link for further deatils

This unit must be installed at the hottest part of the system. In a heating system this is the main flow from the boilers. The static head must not exceed 30 metres.

In a chilled water system the unit must be located in the return close to the chiller. Maximum static head must not exceed 15 metres.

N.B. if the static head is greater than these figures the efficiency of the Cleanvent is reduced. The maximum flow rate through the Cleanvent is 3m/sec. If these values are exceeded the efficiency is reduced.

Commissioning

The Magvent requires no special commissioning .

Maintenance - Removing & cleaning the Magnetic rod

Isolating valves should be installed either side of the connecting flanges on the unit. Close the two isolating valves. Secondly open the ball valve located on the bottom of the unit or the fast bleed valve. Care should be taken as the water may be very hot. Then remove the bolts located on the single front blank flange. Then remove the blank flange with the magnate attached. Extreme care should be taken at this point as the magnate is very powerful. Remove all attached debris on the magnetite. Once the magnate is clean and free from debris please re-insert into the main body of the unit. Tighten all bolts on the flange; close all valves on the unit. Open the two isolating valves (slowly) and check for leaks (around the gasket on the blank flange).

Maintenance will be required to remove trapped Dirt and Sludge. Opening the ball valve at the bottom of the unit will flush out non magnetic dirt and sludge, The valve may be opened while the system is under pressure.

Scalding is a danger at high pressures and temperatures. Ensure that the water is safely piped to drain before opening the valve.

The system pressure will flush the dirt out. Leave the valve open until the collected dirt has been flushed out, repeat this operation every few days. Once the water is clear it may be possible to drain every 6 months or so depending on the size and age of the system.

Dirt separators can only remove Magnetite, Dirt and Sludge that is circulating.

Flanges

All flanges are drilled to BS 4504 PN16 as standard. Plain ends and other flange rating are available on request.

Drain valve

All models are supplied with a ball valve for draining the collected dirt and sludge.
