Fact Sheet
DSA HOME
District heating substation up to 25 / 40 kW
1)
FEATURES AND BENEFITS
• Substation with high efficiency
brazed plate heat exchangers
for one family houses, made
from acid-proof stainless steel
• Wall-mounted construction
• Suitable for new buildings as
well as renovation projects
• Small, lightweight,
compact construction
• Electronic controllers for heating
and domestic hot water systems
• Fast and reliable delivery
• Fast and easy installation
• Danfoss substations and heat
exchangers are manufactured
according to European Pressure
Directive PED 2014/68/EU
Application
The DSA HOME is designed for use in
high-parameter district heating networks. Suitable for heating single houses. It provides an alternative solution
to an oil or gas boiler. The DSA Home
is designed for heating or heating and
domestic hot water. The wall-mounted
construction saves space needed for
installation and servicing.
Flexibility
The new DSA HOME is offered as 1- or
2- circuit module. In addition, primary
modules (including ball valves, strainers,
differential pressure regulators and heat
meters) can be ordered as accessories.
Primary modules can be connected to
either the right or the left side, without
any modification to the construction.
Construction / Installation
The DSA HOME is designed as a wallmounted station. Each station is
equipped with micro plate heat exchangers manufactured by Danfoss,
which significantly increase substation
performance and lifetime. All components are placed at the front of the station, which makes it very easy to access
them during maintenance or servicing.
Due to the Euro-pallet size, it is possible to transport the DSA HOME with
a small van. The mounting equipment
significantly reduces the time required
to mount the substation to the wall.
The standard station layout means that
the piping can easily be prepared in
the room where the substation is to be
installed before the substation is delivered, which reduces the time between
delivery and start-up. Piping prepared
with automatic welding machines
ensures the highest possible welding
quality.
Equipment
The DSA HOME offers a wide variety of
additional accessories, such as substation cover or primary modules. It can
deliver with neither with ECL310 with
communication functionality or with
ECL110 .
