Hermetic bi-ﬂow ﬁlter drier Type DMB and DCB

DMB and DCB are for use in liquid lines on heat pumps.

Hermetic bi-ow lter driers, types DMB and DCB are for use in liquid lines on heat pumps.

Hermetic bi-ow lter driers have built-in check valves which ensure that refrigerant liquid always ows through the lter driers from the outer side of the lter core towards the center. Thus all dirt particles are retained irrespective of ow direction.

DMB and DCB lter driers ensure fast and eective adsorption of moisture as well as organic and inorganic acids.

When building heat pump systems, the use of bi-ow lters can, depending on the type of system, save up to ten solder connections. This reduces production costs and the number of potential leakage points.

Available with are and solder (cu-plated steel) connections.

Hermetic bi-ow lter drier, Type DMB and DCB

Features

The Core type DMB

• 100% 3Å Molecular Sieve core

• High drying capacity minimizing the risk of acid formation (hydrolysis)

• Recommended for use with HFO, HC, HFC and HCFC refrigerants

• Will not deplete oil additives

The Core type DCB

• 80% 3Å Molecular Sieve with 20% activated alumina

• Perfect core blend for systems that operate at high condensing temperatures and require high drying capacity

• Recommended for use with HFO, HC, HFC and HCFC refrigerants

The Shell

• PED approved for PS 46 bar

• Available with are and solder (cu-plated steel) connections

• Optimum ow characteristics and dirt retention

• The check valves are not sensitive to dirt and give minimum restriction, irrespective of ow direction

The Filter

• Eective dirt removal to 25 μm

• No dirt released by reversing the ow direction

• Available in sizes 8 – 30 cubic inches
