The STB 200, 300, 600 and 850 stainless steel (inox) solar do-
mestic hot water tanks, are engineered for the heating and
storage of domestic hot water from solar energy and from
other sources of heating. The tanks are made of stainless
steel, which assures high level of hygiene. Use of the latest
technologies and carefully researched development delivers
the most economical use of all available energy sources.
Possible upgrade
of the system with digital solar controller Cm-Sol. Produced in
compliance with ISO 9001 and ISO 14001 norms.
PRODUCT CHARACTERISTICS
EFFECTIVE
By using modern technologies and proven tech-
nical solutions, high heat transfer coefficients
and negligible environmental losses are
provided.
STEEL
The boilers are made of stainless steel, guaran-
teeing high hygiene conditions.
ISOLATION
The insulation layer of 80 mm thick effectively
protects the boiler from heat losses.
SOLAR SYSTEMS
They are intended for heating and accumulating
DHW using solar energy.
•
STB solar hot water heaters, with volumes of 200, 300, 600 and
850 litres, are engineered for heating of domestic hot water with
solar energy, with a boiler and for alternative heating using the in-
ternal electrical heater.
•
They are made of high quality stainless steel, which guarantees
high hygiene standards.
•
Pipe connections are located on the rear side which enables simple
and fast connection into the heating system.
•
Thermal insulation 80 mm effectively cuts heat loss.
BASIC DIMENSIONS:
CONNECTING TO WATER SUPPLY:
Cm-SOL SOLAR AUTOMATIC
CONTROLLER:
CmSOL controller can control solar heating up to 4 separate
tanks with 1 or 2 solar collector fields and heating the first tank
using conventional sources – an el. heater and up to two
boilers.
Controller has 10 inputs, 8 outputs and 2 PWM and 2 analog
outputs for collector pumps.
Types of solar collectors can be chosen between flat plate and
vaccum tube solar collectors.
Types of tanks can be selected between DHW tank,
accumulation tank, accumulation tank with built-in DHW tank
and swimming pool.
Hydraulic connection of the multiple tanks can be selected via
pumps, 3-way zone valve and 2-way zone valve.
It is possible to control the pump for heating the first tank with
the next one (heating the DHW tank with the accumulation
tank).
The first tank can be heated by an el. heater (via contactor)
and with up to 2 conventional heat sources.
The controller can control the recirculation pump with impulse
operation at the set schedule time.
By entering the correct flow through the solar collectors and by
installing the solar collector backflow sensor, sollar controller
calculate total gain energy from solar collectors. If the flow
meter is installed, the calculation of the energy will be more
accurate.
In addition to the upper mentioned, the controller also has
protective functions: solar collector cooling function (via tank),
tank cooling function (over solar collector or recirculation),
disinfection function (legionella protection) and pump/valve
protection function for blocking protection.
On the controller you can determine the priority of solar
heating of a single tank, switch on a tank heating priority test,
switch on/off certain tank from the heating, switch on one-time
heating with conventional sources, switch on party option for
one-time heating extension and switch on the holiday option
with which are automatically switch on all protective controller
functions to allow the overheating/freezing of the collector to
be minimized.
To monitor the operation of the solar system, it is possible to
install a Cm WiFi-box and through the web portal
monitortheindividual temperatures and operation of individual
pumps and valves. Through the web
portal it is also possible to change the set temperatures of the
tank and solar collector.
