SolexMaxi TW up to 100 m²
Application range: up to 100 m² collector surface
with heat quantity measurement according to the BAFA promotion directive for solar thermal systems
The CE-conformity of the installation has been certified according to DIN EN 60335.
Connections primary: 1" internal thread, connections secondary: 1 ¼" external thread
All fluid-carrying parts made of brass or stainless steel, fully assembled - self-sealing or flat-sealing
Premounted on steel wall bracket
can be easily mounted to the wall Full port ball valves or piston valves
Check valve in the return ball valve, can be opened, 200 mm wc, especially for solar systems, prevents unwanted circulation.
Solar circuit with large ball valve handles
easy handling, visible closing position, with integrated full metal thermometer 0-160 °C, can be pulled off, with immersion sleeve integrated in the ball valve, piston valves in the secondary circuit
Airstop in the flow line
for permanent deaeration of the heat transfer medium
Basic version with solar circulation pump by Grundfos, Premium version with high-efficiency pump by Wilo (PWM for speed control), already installed and prewired, adapted to the performance of the transfer station, pumps can be isolated completely, no draining necessary during pump service
Premium version: electronic flow rate sensors for the performance depending on speed control of the secondary pump as well as heat quantity balancing (secondary), pressure sensors with evaluation unit for system monitoring
Flush and fill unit integrated
two fill and drain valves (on the safety group and on the elbow gland of the heat exchanger) permit filling and flushing of the primary circuit as well as only the heat exchanger, secondary circuit with vent valve at the highest point of the heat exchanger
Solar safety group
solar pressure relief valve 6 bars, pressure gauge resistant to high temperature 0-6 bars with valve, flat sealing connection for an expansion tank, secondary side with pressure relief valve 10 bars
Compact design insulation with optimised function
made of durable elastic EPP, entirely insulated valves and fittings - excellent ventilation and cooling of the pumps, minimal heat losses
Safety instructions The installation and commissioning as well as the connection of electrical components require technical knowledge commensurate with a recognised vocational qualification as a fitter for plumbing, heating and air conditioning technology, or a profession requiring a comparable level of knowledge [specialist]. The following must be observed during installation and commissioning: - relevant local and national regulations - accident prevention regulations of the professional association - instructions and safety instructions mentioned in these instructions.
WARNING Danger of scalding due to the escape of hot fluids! With pressure relief valves, there is a risk of scalding due to the escape of vapour or hot fluid. Please ensure for each pressure relief valve that no personal injury or material damage may occur due to possibly escaping medium. - Install a discharge line. - Observe the instructions regarding the pressure relief valve. - The pressures for the expansion tank calculated by the plant designer and the operating pressure of the installation must be set. WARNING Personal injury due to contaminated domestic water! Heating water contains harmful substances that must not be washed into the domestic hot water circuit. If the station has been used to charge a buffer tank, there is still heating water in the valves and fittings and in the pump of the secondary circuit, even after draining. The heating water cannot be completely removed. -The station must not be connected to a domestic hot water circuit any more.
CAUTION Personal injury and material damage due to overpressure! Closing both ball valves in the primary circuit will separate the safety group from the heat exchanger. A rise in temperature in the storage tank may result in high pressures, which may lead to personal injury and material damage! - Only close the ball valves for service and maintenance. - When closing the ball valves in case of servicing, also put the pumps out of operation and close the ball valves / piston valves of the secondary circuit. CAUTION Risk of burns! Valves, fittings and pump may heat up to more than 100 °C during operation. The insulating shell must remain closed during operation.
NOTICE Material damage due to mineral oils! Mineral oil products cause lasting damage to seals made of EPDM, whereby the sealant properties get lost. We do not assume liability nor provide warranty for damage to property resulting from sealants damaged in this way. - It is imperative to avoid that the EPDM sealing elements of the unit get in contact with substances containing mineral oils. - Use a lubricant based on silicone or polyalkylene and free from mineral oils, such as Unisilikon L250L and Syntheso Glep 1 of the Klüber company or a silicone spray.
