SONDEX A/S SONDEX RomaniaCOMPACT SUBSTATIONS FORHEATING AND TAP WATER

COMPACT SUBSTATIONS Danish Technology Adapted to the Specific Requirements of the European Market

COMPACT SUBSTATIONS FORHEATING AND TAP WATERThe compact substations are prefabricated systems, fully equipped and automated, using hot fluid produced in a centralized source on primary side in order to heat the fluid on the secondary side used for the preparation of the heating and tap water.

COMPACT SUBSTATIONSTHE OPTIMAL ENERGETIC SOLUTION, as a result of using the highest performance equipment, included in various schemes of processes already verified in practice, with automated controlling of functioning.FLEXIBILITY, due to the fact that they can be designed to function both with steam and hot water on the primary circuit.GUARANTIED QUALITY of execution of equipment in industrial conditions.RELIABILITY of the industrial manufactured, assembled and tested equipment.COMPACTNESS of a well studied design.EASY INSTALLATION, with minimum works on the building site, necessary only to connect the equipment to the customers installations.EASY AND SAFETY OPERATION due to the system of control and automated regulation which includes also the interface with different monitoring systems, and to equipment easy to maintain and to the service provided by our team with specialized members.

COMPACT SUBSTATIONSEven if there is a standard range of SONDEX compact substations with defined parameters (that could be assembled and delivered to any client who is interested in such units), our team of specialists can design and produce such units according to the specific requirements of the client related to:dimensioning the district heating systems based on the technical parameters, the pressure and the phase (liquid phase or steam phase) of the fluids;personalization / optimization of the functioning schemas based on the specific technical requirement of the application;construction adapted to the configuration of the space room and access routes;Design of compact substations either horizontally or vertically and solutions to build such units inside protection cupboards or containers (for high capacities);optional tools available, according to the clients needs;technical solutions provided for special conditions of the fluids used in the applications (i.e. geo-thermal water, salt water, carbo-gazous mineral water etc).

Elements included in a compact substation:standard components: plate heat exchangers, automation for regulating of the temperature and/or pressure, expansion tanks, circulating pumps, safety-valves, pipes for connecting (threaded, welded or with flanges), separating valves, filters, thermometers, manometers, frames;optional components: recirculation of tap water between the heating station and the consumers, electric panel, storage tank for tap water, automated water-supplying (filling) systems, energy and flow meters, electro-magnetic lime dissolver, interfaces for monitoring and telegestion systems, insulations.

Explanations regarding the codes used for identifying the range of standard units:

ACM: preparation of tap-water instantaneously;ACM-(SI): preparation of tap-water semi-instantaneously (via a storage tank);( l): volume, in liters, of the tap-water storage tank;INC-D: direct heating (no plate heat exchanger);INC/P: indirect heating (with plate heat exchanger) in parallel with the tap-water;INC/S: indirect heating (with plate heat exchanger) in cascade with tap-water;INC: heating without preparation of tap-water;... kW/ ... kW: heat capacity (based on the input parameters), in kW, on the heating and on the tap-water circuit;GEO: use of the geo-thermal water as primary fluid;PHE: SONDEX plate heat exchanger

Dimensioning a Compact SubstationEach Compact Substation needs a separate design for all components depending on the requirements of each situation and the specifications of the planner.
