Description
• Pressure-resistant storage tank and external shell & tube heat exchanger
made of high quality corrosion resistant stainless steel 1.4571/Duplex.
The systems comply with the DVGW guidelines for reducing a Legionella
infection risk at large-scale systems.
• Optimum hygiene through short storage time of the hot water, low standby
losses and small space requirements of the compact system due to
high performance of the heat exchanger and small storage capacity.
• Fibre-fleece insulation of storage tank with robust outer sheathing made
of PP (RAL7037), patented aluminum closure strips and self-fixing
closure caps, quick and easy installation, 80mm insulation up to 1,000
litres and 100mm above. 100% recyclable, fire protection class B2
(B1 upon request)
• Highly efficient heat transfer and most extensive prevention of liming
and scaling through self-cleaning effect of patented shell & tube heat
exchangers with free floating turbulator rods made of stainless steel.
• Constant hot water temperature during charging and thus the highest
comfort at the hot water supply by primary flow adjusting by a motorized
three-way control valve. Heat exchanger unit is pre-assembled and prewired.
Primary pump and control valve are provided loosely for flexible
on-site assembly.
• Safe plant operation without danger of creeping performance decrease
due microprocessor controlled storage regulation with differential pressure
monitoring of the shell & tube heat exchanger. The internal and external
(optional) cold water flushing after completion of the charging process
minimizes effectively scaling by the rapid cooling of the heat exchanger.
• Microprocessor control with touch screen for clear and easy use. Possible
remote monitoring and remote control of the system through Ethernet
interface. Logging and monitoring of the performance of the system and
the individual components.
• Production by TÜV certified welding company according to HP-0 and
ISO 3834-2, approval to SVGW, ÖVGW and DVGW and certified
according to ISO 9001: 2008.
• Simple installation and short mounting time due to pre-assembled units.
• Maximum pressure/testing pressure: secondary 6/9bar; primary 10/15bar
