Micro plate heat exchanger (MPHE): XB 52

Description

Micro Plate Heat Exchangers - a revolutionary technology from Danfoss.

Characterized by their unique plate pattern, MPHEs enable heat to be transferred more efficient than any previous model of heat exchangers.

Benefits:

•Energy and cost savings

•Better heat transfer

•Lower pressure loss

•More flexible design

•Longer life time

Design and function

T11	-	Primary side in
T12	-	Primary side out
T112 -		Primary side second inlet
T21		(2-pass)
	-	Secondary side in
T22	-	Secondary side out
T212 -		Secondary side second
		inlet (2- pass)

Danfoss 2 pass heat exchangers are made with 6 connections, as they are primarily used to heat tap water.

There is one additional connection to allow circulation of hot water and one connection to connect and extract heat from return water from heating heat exchanger.

Connections T112 and T212 can be blocked if they are not used.
