ECOCONDENS CRYSTAL PLUS 50 boilers are intended to heat large areas (large single-family houses, multi-family residential buildings, tenement houses). Devices belong to ecological and economical heating units. By using ECOCONDENS CRYSTAL PLUS 50 you may build a heat-only boiler station with power up to 225 kW. All the devices are connected in cascade by one cascade manager.
  • heat exchanger made of stainless steel
  • new generation stainless steel heat exchanger with aluminium burner door, resulting in less heat loss
  • stepless speed regulation fan (controlled electronically)
  • cylinder burner made of stainless steel – low level of NOx emission (5th class)
  • modern and transparent control panel
  • complete system of safety measures
  • works with cascade managers
  • circulation pump with automatic air-vent
  • Open-therm system available.
