Wall-mounted
gas double-circuit boilers Protherm Gepard with a capacity of 12 and 23 kW for
heating and hot water preparation in a stainless steel plate heat exchanger.
Technical
features:
• Reliable,
copper heat exchanger.
• Bright
LCD display.
• Coaxial
chimney.
• Robust
stainless steel secondary heat exchanger.
• Composite
hydraulic block.
Using the
liquid crystal display, you can continuously receive information at any time
during the operation of the boiler. The display allows you to constantly
monitor the entire process.
Models 11
MTV and 23 MTV can be equipped with a coaxial exhaust gas system and do not
require connection to a chimney, which allows them to be installed in rooms
where there is no stationary chimney or its installation is very difficult or
impossible due to various reasons.
Switching
to DHW mode occurs automatically when the hot water tap is opened. The main
feature of the boiler is the rapid heating of water, about 2 seconds.
The
reliability and durability of the boiler is ensured by a hydraulic block made
of durable composite material. The copper heat exchanger and burner made of
chromium-nickel steel, the plate secondary heat exchanger made of stainless
steel once again emphasize the quality of the boiler.
The new SIT
pneumatic gas valve is quieter than the previous generation gas valve.
