MCI. Condensation modular thermal unit

Series MCI

Condensation modular thermal unit

  • Ultra-high thermal performance.
  • Forced air double burner with total premixing with very low NOx and CO emission.
  • Management of element cascade.
Series MCI
  • Thermal unit consisting of a self-supporting frame with a cataphoresis treatment and coating protection, with casing in treated steel to increase outside resistance.
  • The casing features an internal 20 mm thick stiferite insulation covered with an aluminium film.
  • Thermal units consist of:
    - a thermal element (Condensation heat generator) prepared for sliding temperature operation;
    - prearrangement for DHW production;
    - insulated and flanged steel system return and delivery manifolds;
    - gas manifold;
    - condensation discharge manifold for draining of a single thermal element.
  • Thermal element with boiler body made of:
    - stainless steel primary heat exchanger;
    - forced air double burner with total premixing with very low NOx and CO emission;
    - double gas solenoid safety valve with constant air-gas ratio (pneumatic);
    - high head fume discharge electric fan for electronic speed control;
    - modulating high head ErP circulator;
    - degassing chamber with automatic bleed valve;
    - water circulation safety differential pressure switch;
    - minimum water pressure switch.
  • Total modulation both in heating and hot water mode (For external DHW application only).
  • Ultra-high thermal performance (4 stars 92/42 EEC).
  • NOx class 5 emissions (according to EN 483:1999).
  • Electrical protection IPX4D.
  • Internal instrument panel with electronic microprocessor control and ignition card;
    - NTC sensors for delivery and return temperature detection;
    - setting of desired heating temperature;
    - electronic ignition;
    - programming and power increase according to needs;
    - antifreeze and anti-seizure functions for circulator with programmable post-circulation;
    - complete diagnostics of functions with shutdowns indication.
  • Management of element cascade.
  • Approved safety, protection and control devices (ISPESL/INAIL) installed inside the unit comprising:
    - 5.4 bar safety valve;
    - regulation and cut-out bithermostat;
    - maximum pressure switch;
    - minimum pressure switch;
    - pressure gauge with pressure gauge holder cock;
    - thermometer with control trap; - fuel shut-off valve (optional).
  • Flow balancer kit (accessory).
