Cleanvent Dirt Separator Demountable CVD-R

Dirt and Sludge Removal from Heating / Chilled Water Systems

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 Cleanvent (CVD) is used to remove Magnetite Sludge and Dirt. Installed on the return pipe in the system the Magvent (CVD) will eliminate all types of dirt particles from heating and chilled water systems.

Dirt Removal

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

The Solution

The Cleanvent removes dirt. Installed on the return pipe in the system the Cleanvent will eliminate all types of dirt particles from heating and chilled water systems down to 10 microns.

Features

• Greatly reduced commissioning times after initial fill.
• Longer system life (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)
• Large collector ensures that flushing is only required periodically
• Can be flushed while fully operational (no need to shut down)
• An internal stainless steel concentrator to aid removal of dirt.

This unit must be installed in the return pipe of the system.

Two number flanges are installed to enable Dirt Separator to be split to aid removal of filter media.

Commissioning

The Cleanvent requires no special commissioning .

Maintenance will be required to remove trapped dirt and sludge. Opening the ball valve at the bottom of the unit does this. 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 dirt 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.
