Wooden chops boiler EKO-CKS-MP 170 - 580 KW

Hotwater steel boilers EKO CKS Multi Plus are designed for burning wood chips P16A/B-P45A,M35 (G30/W35, G50/W35) or wood pellets with diameter 6 and 8 mm class A1 and A2. 
- Manufactured with nominal heat powers from 160, 250, 340, 450 and 580 kW 
- The boiler must be connected with an accumulation tank (min. 12 lit/kW) 
- Max. operation temperature 95 C 
- They can be installed in open and closed heating systems 
The basic scope of delivery consists of: 
- Boiler with thermal insulation 
- Staired combustion chamber with moving elements to insure lower sensitivity due to the change of fuel quality 
- Electrical cabinet with digital boiler regulation with touch screen 
- Automatic ash removal from the combustion chamber 
- Cyclone with ash container for the separation of flying ashes out of the flue gases, centrifugal fan with rpm controller 
- Conveyor-1 with motor for the fuel supply into the combustion chamber 
- Connection box with built in backfire flap (RSE) and backfilling sensor -
Thermal protection of the boiler is made with 2 tube heat exchangers with thermal safety valves 
- Lambda probe

• Basic control unit includes : 
  - Regulation by a lambda probe of the primary and secondary air, rpm change of the underpressure fan at the flue gas exit (from the boiler) and the correction of the feeding conveyor-2 
  - Pressure control in the combustion chamber 
  - Boiler return flow protection (steering the actuator responsible for the return temperature increase and pump control between the boiler and buffer tank) 
  - Steering/controlling of: feeding conveyor-2 for wood chip or wood pellets, conveyor-3 for wood chip or wood pellets, conveyor- 3 for supply of wood chips or wood pellets from the fuel container, fuel mixer in the fuel container, conveyor for ash removal from the flue gas chamber and with other additional equipment listed below. 
  - Control of the buffer tank heating, DHW tank and DHW recirculation 
  - 1 boiler temperature sensor, 1 return flow sensor, 2 buffer tank sensors, 1 outdoor temperature sensor, 1 DHW sensor, 1 DHW recirculation sensor
• Obligatory equipment : 
  - Feeding conveyor-2 for wood chips/pellets 
  - Feeding conveyor-2 extension for wood chips/pellets 
  - Return flow protection with 3 way mixing valve and actuator and boiler pump 
  - Wood chip/pellets mixer separately and auger/conveyor-3 for the supply of wood chip/pellets from the fuel tank or mixer of wood chip/pellets with auger/conveyor-3 or wood chip tank with mixwer and auger/conveyor-3 
  - Wood chip/pellets mixer conveyor extension (if needed) 
  - Buffer (accumulation) tank
• Additional equipment: 
  - Automatic pneumatic air clenaing of boiler flue heat exchanger passages 
  - Compressor with compressor kit 
  - Automatic ash removal system out of the flue gas chamber (by help of a screw) 
  - Security/safety elements set min/max boiler water pressure 
  - CM2K-B – module for 2 heating circuits (max. 4 x CM2K-B module) 
  - CSK – room corrector (possible installation only together with the CM2K module) 
  - CAL – alarm module 
  - CM-GSM – communication module 
  - CM WiFi-box – boiler operation monitoring by PC, tablet computer or smartphone 
  - CMNET – cascade manager 
  - Hot water tank 
  The boiler is manufactured according the EU norms EN 303 – 5 :2012 , ISO 9001 and ISO 14001
