District cooling substations for commercial, industrial and residential buildings

Designed for cooling application

District cooling substation is de­signed for industrial, commercial
and residential building applications
connected to a district cooling net­work. Building owners save space by
using pre-fabricated skids compared
to build-on-site solutions, and expe­rience proves a lot lower investment
costs. Further there is a complexity re­duction as mechanically and electri­cally installations reduces the require­ment to skills of workforce. Danfoss
has more than 40 years of experience
in production of substations, which
guarantees great functionality.

High ΔT guaranteed

Smaller substations are designed with
MicroPlate® brazed – and the larger
equipped with gasket heat exchang­ers from the Danfoss XGF range. Both
heat exchanger types ensure that
substations will have high ecien­cy, reduced service cost and longer
life time in compare with traditional
cooling systems. The combination
of Danfoss` ECL controller with dif­ferential pressure, temperature and
ow control valves oers an excellent
temperature control and hydronic
balancing of the network. As result of
using pressure independent control
valves “low ΔT syndrome” is avoided,
when Danfoss` guidance for the HVAC
installations is followed.

Remote controlling
and monitoring

Danfoss automatic controller ECL
oers more possibilities for external
communication. Traditional SCADA
solutions can communicate with the
controller via a Modbus protocol.
Further Danfoss oers a web-based
SCADA solution called ECL portal (ecl.
portal.danfoss.com), which enables
remote controlling, monitoring and
alarming functionalities from the sub­station. Visualization of the ECL portal
gives you easiness of use, and access
via PC or Smartphone improves the
level of service and reduce costs due
to 24/7 access.

Prefabricated substations enable
top quality and shorten installa­tion work on the building site

District cooling substations are
produced based on a 3D model pre­pared by our design department.
Based on customer requirements all
components like: heat exchangers,
control valves, pumps and measuring
equipment are virtually placed inside
the technical room and connected
with piping. Based on 3D-drawings
pipes are bent, cut and welded with
support of automated machines
ensuring supreme quality and short
delivery time. Large substations are
designed as modular constructions,

FEATURES AND BENEFITS

• Substations with high quality
components designed for cooling
applications fully customized by use
of 3D-tools to t individual needs

• All control components in the substation
are high quality Danfoss components
like: heat exchanger, control valves,
shut-o valves, energy meter, shut­o valves and automatic controls

• Danfoss prefabricated substations
reduces space demand approximately
30% compared to build-on-site solutions

• Easy to install and use with remote
access via Internet or via other
communication protocols like MODBUS
or Danfoss free cloud based ECL Portal

• All Danfoss products are manufactured
according PED 97/23/ EC European
Pressure Directive, and Danfoss is
compliant to ISO9001/ISO14001/
TS16949 automotive standards
to ensure error free products

which makes transportation and
assembly easier. Substation includes
an electrical wired panel, which is
functionally tested and ready to use
after connecting power supply to the
cooling substation on site. Special
pipe clamps prevent thermal bridges
and condensation at support points.
Danfoss substation is a complete
product: designed, produced and
tested – ready for use.
