STB (200 – 850 lit.)
The STB200, 300, 600 and 850 stainless steel (inox) solar domestic 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.
They are intended for heating and accumulating DHW using solar energy.
The boilers are made of stainless steel, guaranteeing high hygiene conditions.
By using modern technologies and proven technical solutions, high heat transfer coefficients and negligible environmental losses are provided.
The insulation layer of 80 mm thick effectively protects the boiler from heat losses.
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 internal 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.

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.
