Unical Boiler – MODULEX

MODULEX - Family Packaged Smoke Tube Steam Boilers

Unical Boiler – MODULEX is a compact, gas-fired, Low NOx, condensing boiler designed with multiple modules for versatile operation.
  • Each boiler body consists of two or more modules (4 to 8), enclosed in a single protective casing, capable of operating independently or in cascade.
  • Managed by a single microprocessor controlling operational and safety temperatures.
  • Efficiency: The ICI boiler can achieve 103% efficiency at full load (30/50°C) and 108.3% at part load (30% nominal, 30°C return).
  • Components: Each module includes a combustion chamber, metallic fiber pre-mix burner, modulating fan, gas valve, ignition electrode, flame detection, NTC sensor for management control (BMM), and local temperature and safety thermostat.
  • Temperature Control: Equipped with NTC sensors for global temperature control on flow and return manifolds.
  • Insulation: Integral, non-allergic synthetic wool insulation.
  • Burner: Fully pre-mixed, radiating, modulating, metallic sponge burner with automatic no return diaphragm.
  • Nominal Input: Each ICI boiler module ranges from 22 kW to 108 kW.
  • Noise Level: Operates at a noise level of less than 49 dBA at maximum output.
  • Configuration Options: ICI Boiler allows for cascade installations and integrates with Supermodulex for expanded heating capabilities.
  • Operation Logic: Includes output sharing for efficiency, automatic operation hour splitting, D.H.W. production control, and module-specific output adjustment.
  • Control Features: Enables precise heating request control, boiler and temperature status monitoring, alarm management, parameter settings, relay control for pump operation, and analogical output for modulating pump control.
  • Emergency Operation: Ensures continuous heating system operation during communication interruptions with the automation system.
  • Additional Features: Includes integral easily removable painted steel panels, adjustable smoke exhaust pipe, condensate collecting tank with drain siphon, stainless steel smoke chamber, built-in air vent, and comprehensive sensor package.
