HEATING TECHNIQUE
Steel hot water boilers EKO-CKS Multi Plus with 170 580 kW heat output designed to be fired by wood chips and wood pellets. They can be installed in both closed and open central heating systems in medium and large facilities. Automatic operation of these systems provides the user with enviable comfort and makes the system suitable for wide application. Boilers are equipped with a moving grate for fuel burning, a lambda probe, an automatic fuel feeding system, automatic ignition, thermal protection, automatic ash removal from the combustion chamber and cyclone to extricate particles from flue gasses. They are distinguished by a successful combination of modern technologies and quality construction materials s well as simplicity of installation and use. Proven technical solutions make these boilers safe and reliable in operation.
PRODUCT CHARACTERISTICS
Boiler class 5. They are designed to be powered by P16A/P16B – P45A, M35 (G30-G50, W35) class wood chips and E ENplus A1 and A2 class wood pellets. They can be installed in both closed and open central heating systems. After a change in type, size or moist content of the fuel it is necessary to adjust the settings of the system. There is an option of pre- adjusting the parameters for some fuel types. Required power supplies: 380/400 V. The boilers are equipped with: Digital boiler control with a touch screen display which controls the operations of the boiler, fuel supply transporter and has an option to control up to two additional fuel transporters and a mixer in fuel storage. Moving grate for fuel combustion. Lambda probe. Automatic fuel supply to burner by means of screw transporter, automatic ignition and automatic ash removal from the boiler. Flue gas extraction fan and cyclone for flue gas particles extrication. Flue gas tube turbulators, thermal protection against overheating, protection against backfire into the fuel storage (backfilling sensor, flap)
SUITABLE FOR THE ENVIRONMENT Serialized built-in cyclone for separating particles from flue gases.
ECOLOGICAL ENERGY SOURCE Designed for wood chips and wooden pellets.
AUTOMATION The automatic operation of these systems provides the user with enviable comfort and makes these systems suitable for wide application.
ACCESSORIES Various accessories for specific applications: CM2K, CMNET (cascade manager), CAL, CM-GSM (alarm alert and boiler ignition / boiler via SMS) etc.

Wood chip feeding systems from a storage – room (enclosed space)
These systems are designed for wood chip and pellet transfer (max. moisture content up to 35 %) from a storage room to the firing equipment EKO-CKS Multi, EKO-CKS Multi Plus. They are equipped with a rotating plate with springs for wood chip mixing (Ø 1,2 - 5m) connected to a screw transporter (2,5-8m) which is driven by an electric motor with gearbox. The system is operated by the digital control of the boiler in its standard configuration.
