SPX HWB UNITS
APPLICATIONS
The SPX HWB Units provides hot water for
domestic purposes and are suitable for:
-
residential housing
hotels and leisure facilities
schools
hospitals
factories
The SPX HWB units use hot water from a
boiler as primary heat carrier and produce
hot water for domestic purposes in semi
instantaneous conditions. These units
provides a continuous flow rate for medium
needs of consumer but provides a large flow
rate for peak demands also.
In standard version these units are
equipped for independent fully automatic
operation.
In basic version the unit control and the
pumping on primary side will be in client
charge.
FEATURES AND BENEFITS
 Combine the benefits of an instantaneous preparation in a high efficient plate heat
exchanger with the storage of hot water in the buffer tank
 Charging pump of buffer tank integrated in unit in any version
 Hot water flow rate control for any version
 Primary pump and control valve integrated in unit in standard version
 Reduced required boiler capacity
 Advanced control for economic operation conditions in standard version
 Buffer tank insulation inclusive
 Pumps according to ErP 2009 / 125 / Ce directive
 Easy operation with minimal maintenance
 Compact design and strong structure for floor mounting
 Supplied in kit for easy installation
 Manufacturing under ISO9001, ISO14001, ISO18001 and PED 97/23/EC rules
