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.

For other connections please contact your
Danfoss Sales Representative.

harmful to the system

Selection example

Select the appropriate type (DMB or DCB) based on refrigerant and oil type. Then select the drier size based on the
adsorption and liquid capacity required.

• Amount of charge: 15 kg R134a at tL = 24 °C To dry 15 kg R134a at 24 °C from 1050 to 60 ppm moisture, a DMB 16
is necessary

• Cooling capacity: Qe = 25 kW, To obtain a mass ow corresponding to 25 kW cooling capacity with a DMB 16 lter
drier, a 1⁄2 inch connection must be chosen. Larger connections can be chosen in accordance with the liquid line
dimension

• Result DMB 164 or DMB 165 can be used

If the initial moisture content is very small or a planned change of the lter drier is considered, a smaller lter drier
size can be chosen.
