MECHANICAL SYSTEMS

An essential aspect that affects the efficiency level of any environment is the condition of its mechanical and hydraulic systems. This encompasses not only the flow and distribution of water but also the circulation of air, air conditioning of spaces, and heating and/or cooling of these areas.

Over the years, the continuous evolution of Elettrica Marras has facilitated the inclusion of qualified technicians in the company, focused on the design and implementation of civil and industrial mechanical and hydraulic systems.

We design and implement mechanical systems such as:

Thermo-refrigeration plants powered by liquid, gas, solid fuels, and electricity, consisting of:

  • Heat generators/chillers/heat pumps
  • Optimization of the building/system
  • Thermal plant, heating system, air conditioning, and air treatment system, realized with B.M.S. systems, with centralized status, operations, and alarms.

– Heating systems:

  • Radiant heating: underfloor, wall, ceiling, thermo-strips, radiant tubes, radiant ceilings
  • Natural convection: radiators
  • Forced convection: fan coils, air handling units, air heaters, ducting, fan heaters, standalone air heaters, rooftop units, air curtains

Air conditioning systems:

  • Radiant cooling with humidity control: underfloor, wall, ceiling
  • Forced convection: fan coils, air handling units, rooftop units
  • Room air conditioning: direct expansion system, heat pump system, chillers
  • Air treatment systems with humidity control
  • Centralized heating systems with thermal energy metering

– Other mechanical systems:

  • Gas distribution systems
  • Exhaust ducts for combustion gases from heat generators
  • Plumbing systems, including wastewater distribution and lifting stations
  • Systems utilizing renewable energy sources
  • Solar systems for space heating integration, domestic hot water production, pool heating
  • Geothermal systems for space conditioning, both ground and groundwater-based, and marine systems
  • Geothermal exchange systems for controlled ventilation of spaces
  • Rainwater harvesting systems for irrigation and/or washing
  • Fire protection systems.
