Energy Services

REDEX Energy Services department is specialized in the implementation of advanced technology solutions aiming at lower energy consumption and maintenance costs.

The specialized team of engineers and scientific collaborators of REDEX Energy Services proceeds to record the energy trail of each installation, quarrying valuable information about electricity quality ( energy study elaboration ).

Applying combinational solutions perfectly adapted to each installation, designs and implements Specific interventions in electromechanical equipment, achieving a significant improvement in operation, power quality and overall energy efficiency.

At the same time, it provides consulting and educational services as well as automated infrastructure control systems, aiming at an essentially reduction of energy consumption by the electromechanical systems, which are mostly involved most in the total energy cost.

 

The energy savings which guaranteed by REDEX are verified by specialized measurement systems and certification based on internationally recognized standards.

Redex offers a pioneering "pay-as-you-save" solutions, which the cost of the investment does not charge the customer, but is repaid by the benefit of the energy savings achieved.

DIRECT FINANCIAL BENEFITS of P. Q.O.S.

P. Q.O.S. QUALITY BENEFITS

Power Quality of an electrical installation is defined by the degree of the waveform deviation Volt, Ampere, and Frequency (Hz from the corresponding established limits of the "net" sinusoidal variation of the power supply network because of the interaction between this network and the electromechanical equipment of the plant.

 

Electrical phenomena that indicate poor Power Quality in an electrical installation is the occurrence of high frequency electrical noise (high levels of Harmonic Voltage and / or Power Distortion), impulse and transient over voltages / asymmetry of phases etc. Such phenomena can cause malfunctions in the orderly operation of the installation even temporary or permanent electromechanical equipment disasters (PLC cards, power supplies, compensation capacitors, etc.).

 

In order to encount with poor quality electrical power, systems must be established, properly dimensioned "custom made" for each application.

 

 

  • P.Q.O.S. are in general, integrated filter systems, consisting of multi-stage LC circuits (L = coil C = capacitor) or LCR (L = coil C = capacitor R = resistance).
  • P.Q.O.S. systems during their operation, use the most advanced technology speed control of electrical parameters such as: Voltage, Current, Harmonics, and Power Factor.
  • Based on the preconfigured parameters, unique to each application, the controllers, activate the appropriate internal steps with "Logical Programmed Scale" response, until the preset values are reached.
  • Systems are equipped with self-diagnosis function, and automatically recognize the status / malfunction per phase and per stage.
  • Each stage is protected , controlled and activated independently in order to  arrange multiple problems and functions at the same time.

 

REDEX`s P.Q.O.S.:

  • Have the ability to settle and cover the entire facility as well as each single load, linear or nonlinear.
  • Improve the power quality, for industrial, hotel, building, regardless of the size.
  • There origin is from German, assembled according to the European Standards and bear all the necessary certifications, using quality industrial components, making them extremely reliable.

Direct Economic benefits, which are included in the guaranteed percentage of the energy savings study:

  • Reduced power demand in KW
  • Reduce energy consumption in KWhs
  • More efficient use of electrical power

 

Qualitative benefits that cannot be quantified and included in the energy savings study, which become obvious with the system operation and have a significant economic benefit:

  • Protection and increase of the electromechanical equipment lifespan
  • Reduced maintenance of the electromechanical equipment
  • Less total inactive time due to interruptions in the production process or its operation installation
  • Increasing the performance of the motors, which will result in the above reduction of harmonics because of the minimization of the torque reverse direction of rotation by the harmonics, mainly of the 5th class , to electric motors
  • Reducing the factors responsible for destroying motor windings.
  • Increased efficiency of power transformers due to reduction of copper and iron losses
  • Reducing unnecessary activations of electrical protection devices (fuse burning, switches drop) and their impact
  • Reduction of potential disasters of the electrical equipment (compensation capacitors, relays, switches, fuses, etc.) as well as problems related with programmable controllers  malfunctions (PLC) from memory loss of related programs etc.
  • Increase of the redundancy of the electrical installation due to in line currents reduction
  • Operating costs reduction

  • Lighting Interventions

Low power consumption LEDs can effectively replace the larger range of lamps used in the facility, consuming up to 80% less energy than the corresponding incandescent or fluorescent lamps


They offer thermal
radiation reduction of the internal space (better thermal comfort conditions, reduced air conditioning costs) and have a significantly increased life span (50,000 hours guaranteed) and zero maintenance costs.

 

Redex Energy Services has a specialized team with extensive experience in lighting issues who support a compose study and the implementation of projects using lamps / lighting fixtures.

  • Leakage currents decrease over earth with special filters

REDEX is specialized in exploring and promoting solutions to the problem of the correct choice and installation of leakage switches (RCDs) for protection against electric shock and fire (according to HD 384 standard) in building and industrial installations.

 

As it is known, since 2006 it is now mandatory for ALL the electrical panels of ALL facilities (building, industrial, etc.) to have adequate leakage switches installed for the protection against electric shock (set to 30mA) and against fire protection for fire protection (set to 300mA).

 

As it is also known, the installation of leakage switches in motion panels and particular in motion panels that feed Three phase inverters or soft starters are almost impossible. The problem is that the leakage switches in such Drive circuits, are immediately activated (trip) at 30mA yet and without apparent leakage (e.g. insulation resistors within limits, etc.).

 

The aftereffect of this problem is to set the leakage switch at max slew-rates (e.g. 500mA) to avoid continuous activations with the result that such relevant protection is NOT provided by the HD384 standard so the specified limits are not met.

 

Redex performs specialized electrical measurements by analyzing the leakage currents and offers custom made solutions with special reduction filters of leakage currents over earth, in order this installation to provide the necessary security and at the same time not to create any kind of problem in the operation of it.
