Components of VIADRUS Space Energy 200F system

Description of main parts that belong to the assembly

VIADRUS Space Energy F collector
At the “heart” of the VIADRUS Space Energy 200F system is VIADRUS Space Energy F flat collector. The collector is a cutting-edge technical solution in solar technology. The main component, which determines the quality of any solar collector, is the absorber and, in particular, the absorption surface which absorbs solar radiation. Formerly, flat collectors used black chromium-coated or nickel-coated copper plates as absorbers. Coatings used currently allow increasing the solar collector efficiency. The flat VIADRUS Space Energy F solar collectors are equipped with absorbers, manufactured by a German company of BLUETEC – SUNSELECT, whose absorption rate is 97 % and the emission factor does not exceed 5 %. According to the tests conducted at the University in Stuttgart SUNSELECT absorbers improve the average annual efficiency of solar collectors by 10 %, the increase in efficiency reaching 16 % in transition periods and winter as compared to black chromium performance. Flat VIADRUS Space Energy F collectors offered at very competitive prices are intended for efficient heating of sanitary water, pools and supporting low-temperature central heating systems.

Structure of the absorber
VIADRUS Space Energy F solar collector was awarded prestigious SOLAR KEYMARK certificate, whichensures high quality of solar products and confirms compliance of the products with the Europeanstandards of EN 12975 and EN 12976.The collector was also subjected to yield test in Germany and was granted Z-W3.104 certificate,which confirms the annual yield above 525 kWh/m2. VIADRUS Space Energy F solar collector can be mounted on both roof and free- standing structures.

Advantages of VIADRUS Space Energy F collectors:

• SOLAR KEYMARK certificate
• ISFH certificate
• highly-selective SUNSELECT type absorber
• special tempered solar glass of increased solar light transmittance, weather-resistant
• made of corrosion-resistant materials (aluminium, copper)
• high energy efficiency

CAUTION !!!
Before the system put into operation, the solar collector must be covered to protect the absorber from overheating. The system should be filled only when the collector hydraulic system is assembled and cannot be put into operation until there is possibility to carry away heat generated by the solar collector.
It is obligatory to use the solar fluid (propylene glycol) provided by the manufacturer. Warranty is not valid, if the collector is filled with water or medium whose parameters differ from those of glycol provided by VIADRUS The collector can be located according the roof conditions available (on a flat or sloped roof) or at any location on a free-standing structure. Under no circumstances may the collector be placed so that the collector top faces upwards as it may result in permanent damage to the collector.

Two-coil vessels of the capacities of 200 litres
Quality you are going to feel We present hereby a new generation of sanitary hot water. The vessels were made to meet current demands of the heating system market and modern solar systems. Vessels can operate with all available gas boilers and other energy sources such as solar systems, heat pumps or fireplaces with water jacket. Wide selection of accessories allows the adaptation of the sanitary hot water system to user’s needs. Characteristics of reservoirs:

• Protection of the inner vessel side from corrosion through an anode and high quality double enamel coat according to DIN 4753.
• Advanced coil welding method (lime-resistant).
• Inspection flange adapted to install an electric heater.

ReSol II controller

• system monitoring display
• up to 4 temperature Pt1000 sensors
• heat balancing
• function control
• user-friendly operation by simple handling
• easy housing installation, outstanding design
• optional rotational speed control,
• solar operating hours counter and thermostat function

Principle of operation
The system is equipped with ReSol II controller, which controls the operation of P1 pump included, in the solar group. The controller turns the pump on when the preset temperature difference between T1 collector and T2 tank is detected.

Single solar group
VIADRUS programme for solar installations allows the connection of the collector to the sanitary hot water heater within a solar circuit. For the installations where the feeding pipes and the return pipes are apart, one- riser “Regusol” pumping module may be used. The filling and draining taps allow to supply the solar circuit with collector liquid and to drain the system for maintenance. To avoid excess pressure within the solar circuit, “Regusol” modules are equipped with safety groups to which an expansion tank may be connected. “Regusol” components are suitable for commercial glycol- based collector liquids.

ELBI expansion vessel
Heating of the working fluid in the collector to a high temperature results in the volume of the fluid being increased. To compensate for the increased working fluid volume a membrane vessel of the capacity of 18 litres was installed in the system

Principle of operation
To protect the system from excessive pressure build-up a safety valve was used in the system, set to the pressure of 6 bar. The valve is an integral part of the solar group. Should a release of the working fluid through the safety valve occur the system must be refilled with identical fluid.

Upon completion of the installation, the authorized company should check if the following activities have been carried out properly

Appropriate selection of pipes and their connection

1. The glycol system pipes should be made of copper or steel. Under no circumstances may PVC pipes be used. It is also possible to use pre-insulated stainless steel pipes however they may not form pipeline sections longer than 10m due to system venting problems.
2. Solder to be used for the system must be of hard type (e.g.: PbCu). Compression fittings with rings may be used instead. Do not use couplings with rubber or plastic parts. Sealing of pipe joints must be made with hemp and sealing paste. It must be always noted that the temperature in the system may reach 280 °C.

Appropriate protection from air-locking
If the pipeline is long and the pipes include so-called U-bends due to the shape of the system, vents should be used at such points to allow better and more precise venting of the system.

Appropriate system insulation
The piping should be insulated along the whole length with coating. Attention must be paid to the coating method and the quality of joints.

System tightness
Check if the system is tight and dry and if no significant pressure drops occur after longer time.

System valves
Check if the collector vent valves were closed on the day after venting was performed.

Filling and venting equipment
Attention must be paid to the venting method exercised by the fitter. The fitter should use professional equipment for filling, flushing and venting of the solar systems. It may resemble the station available in our offer. He may also use other devices equipped with pumps of suitable parameters, which are able to provide a pressure of 5 bar in the system.

1. The best venting method is by the so-called pressure jumps consisting in turning off the pump return pipe to increase the pressure and then quick opening of the valve. If the system is properly vented the pressure should rise very quickly on the valve closing to reach the safety valve limit (6 bar).
2. The system should be vented on both sides i.e. by removing air from both the collectors and the vessel.

Protection of collectors from solar radiation during installation
It is of utmost importance to keep the collectors covered during installation on roof, filling, venting or adjusting. Where possible they should be covered with a film, tarpaulin or original cardboard boxes.

ATTENTION !!! Never turn the face of vacuum tube and flat collectors towards the roof.

Check flow adjustment
Once the system is fully vented check the flow on the rotameter. The flow should be adjusted on the rotameter during manual pump operation (100% speed). According to design values: 0.6 l/min per square meter for flat collectors.
