Mechanical Installations

What are mechanical installations

puzzle

It is the scientific and professional sector that deals with the study, the design and the implementation of systems for either the circulation and power transmission (gearing systems, bearings, etc.) or systems that are subject to high pressure or high temperature (cooling, hydrodynamics systems).

Our company undertakes studies, installation and supervision of mechanical installations in the following fields:

Water supply

Water supplies include the supply of water, its pumping, the whole of waterworks and means by which water is delivered and disposed of to consumers.

Water facilities are divided into four sections:

  • Vertical columns
  • Horizontal distribution network
  • Machinery
  • Sanitary ware and plumbing
  • We undertake the the study, supply and installation of the above water installations as well as the repair and maintenance of the already existing plumbing installations, namely

  • the hydraulic installation
  • the connection of sanitary items
  • repair of any leaking in piping
  • repair and replacement of drainage columns and gutters
  • Drainage

    Sewage plants are divided into two sections:

  • Sewage Plant The sewage installation concerns the sewerage of the various containers in central columns. The linking of the central columns leads to a final horizontal route towards the final recipient (watertight or biological mounds).

  • Rainwater installation The installation of rainwater includes the collection of water from the roof, the balconies and the atrium's. Plastic or metal pipes are used in the vertical routes. The control and collection wells with grates as well as the final drainage are carried out in the following ways: either freely on the plot or on the kennel, or their collection can be completed in a special well and they can be used for irrigation.

    The rainwater tubes, since they are mostly set up outside, should be resistant to solar radiation so that they will not polymerize if they are plastic, otherwise we end up to the metallic ones.
  • Heating

    The technical engineers of our company (mechanical engineers) are conducting design studies for an efficient heating installation according to the needs of your home or business.

    Indicatively, the central heating installation consists of:

  • the boiler
  • the burner
  • the chimney and heaters, or the underfloor system
  • the fuel tank
  • the circulator
  • the safety devices
  • and the piping
  • The fuels commonly used in central heating are oil, liquefied petroleum gas and natural gas. The energy of combustion is transferred to the premises through a heating medium such as water, steam or air using a piping or duct network or a combination of both

    Our experience from the studies and installations we have carried out in all areas of heating in major projects gives us the right to guarantee a proper, efficient, economic heating function with a sound technical installation.

    Air conditioning

    We undertake residential, semi-centralized and central air conditioning..

    In places like residences we have a semi-central air conditioning system in order to avoid the many outer boxes that would be provided by the split units, but also in order to be able to give a uniform temperature to the building.

    The mode of operation depends on living conditions, thermal insulation and machine performance.

    Close your next appointment to discuss your own need for installation. We have the possibility of marketing all the materials for the installations of the above mentioned systems.

    Are you aware of what the heat pump is and why it is so widespread?

    In recent years, there has been a great demand for the installation of a heat pump in both residential and business premises worldwide, as a serious effort is being made to reduce fossil fuels, coupled with the reduction of emitted pollutants.

    What is the heat pump?

    The heat pump is a machine that has the ability to switch over to the cooling cycle of a system so that it can sometimes give hot and sometimes cold air, depending on the air conditioning needs of the room. Specifically, in summer, it removes heat from an air-conditioned room and discharges it to the environment, thus cooling the air-conditioned room, while in winter it removes heat from the environment and emits it into the air-conditioned room and it heats it.

    Comparisons of studies, which have been conducted and which we have been recorded concerning oil, lead to the fact that with the use of the heat pump we have achieved savings of at least 60-70% (depending on the climate of the area), while in the event of natural gas, savings reach 20-30%. The power they consume represents about 1/4 of the energy they deliver and it is intended exclusively for the fan and the compressor, without defrosting resistors that reduce performance. At the natural environment temperature of 7°C the pump delivers heat equal to that of 1 liter of oil, consuming only 2.4Kw/h and, assuming the current value of power to 0.12 € / kW/h, it causes a charge of 0.29€ instead of 1.45€ cost of the power coming from oil. That is, the operating cost is limited at a fraction of 1/5.

    Whether or not it uses the air temperature (air / water pump) or the ground temperature (geothermal pump) in order to transfer heat, it is important that it functions much more efficiently and saves more energy than traditional heating systems (boiler, burner). It is also important to mention that it has almost zero maintenance costs and it solves the problem of autonomy in a room heating and in providing hot water. It is reasonably considered the most economical solution on the market.

    What's the difference from the air conditioner?

    The difference between a heat pump and a common air conditioner is that the heat pump can be used in three ways of operation (air-to-air, air-water, water-water) for both heating and cooling compared to the common air conditioner which uses one way of function ( air-to-air ).

    How do they work?

    The heat pump only needs one source of heat (environmental air), two heat exchangers (one for absorption and one for heat dissipation) and a relatively small amount of kinetic energy (electricity) in order to keep the system running. The pump absorbs thermal energy from the environment. Then, it leads the heat to a certain temperature, making it increase and then delivers it, through the water, to the low-temperature bodies (the underfloor heating system or the fan coil units). Between these two means, the heat circulates through a fluid. As the working fluid passes through the evaporator and absorbs heat from the air, it is converted into gas. At this point, the compressor raises its temperature. Inside the building in the indoor unit heat exchanger, the second heat exchange takes place when the superheated gas condenses and releases heat which in turn warms the room.

    Where can they be applied?

    Resourses of pumping heat are air and soil. Depending on the nature of the resource, the heat pumps are separated into air-air, air-water, ground-air and ground-water. The main application of the air-water pump is the underfloor heating.

    Under - floor heating

    In the underfloor heating, the floor of the room is heated by means of pipelines located inside it, in which hot water circulates.

    The advantages of underfloor heating or cooling are:

  • High thermal comfort with ideal temperature allotment in the room
  • Energy economy
  • Environmentally friendly
  • Charming rooms without radiators
  • Ability to use the same system for cooling
  • Floor heating systems heat up, taking advantage of low floor surface temperatures and uniform heat distribution, thus ensuring thermal comfort. Additionally, they can be combined ideally with gas-fired heat pumps, gas boilers or solar panels, thus increasing the ability of the plant to be environmentally friendly.

    The materials we use are of the best houses in Europe and they are accompanied by a written guarantee and designed specifically for underfloor systems. For the correct choice of machine in each installation, a study by engineers is required, so do not hesitate to contact us

    Fire protection

    Fire protection concerns a set of measures that are taken into account by designers (architects, engineers, mechanical engineers, etc.) in order to protect against fire and its consequences.

    The measures taken are:

  • passive or preventive
  • active or repressive
  • As part of the active fire-fighting measures, we undertake. the study, the equipment and the scheduling of the actions required when a fire occurs and during it.

    Active fire protection measures include (depending on the type and size of the building):

  • installation of portable fire extinguishing means (fire extinguishers)
  • installation of a fire detection system
  • installation of a manual alarm system (alarm button)
  • installation of a permanent water supply network (fire brigade)
  • installation of sprinkler system
