Reactive Power Factor Correction (EasiLiners)

EasiLiners are a product with almost universal application, used to reduce the energy consumption and improve power quality on all types of AC motors. It does this by cancelling a portion of the power normally drawn by these loads, and, more importantly, it does so without negatively affecting horsepower, speed, or reliability.

 

Easiliners reduce the wasted energy normally used by these motors by aligning the phase angle of the supplied voltage and current. This saves energy, reduces heat generation inside motors, frees up new electrical capacity in the facility, and most importantly, it produces a net kilowatt hour reduction on the electricity bill by reducing the alternating current distribution losses in a facility.

 

The Reactive Power Correction System does the following:

  • Extends the life of motors
  • Improve facility voltage
  • Increases electrical capacity
  • Cools overheated lines and panels
  • Lowers kW consumption and demand
  • Improves facility power factor
  • Eliminates power factor penalties, and Lasts for one hundred forty thousand (140,000) plus hours of service

We manufacture a complete range of low voltage, three-phase Passive Harmonic Reactive Power Correction Systems, in a stepped model range from 1.3 KVAR to 30 KVAR, with five (5) voltage lines. They are as follows: 100-240V 1-phase, 200-240V 3-phase, 380-440V 3-phase, 440-480V 3-phase, and 600V 3-phase, for both 50Hz and 60Hz applications. KVAR requirements above 30 KVAR are available by simply paralleling multiple units. All models use an advanced inert gas filled, dry polypropylene and self-healing film, single-mounting-bolt cylindrical capacitor style, which is manufactured in an ISO 9001 certified facility, and includes a CE IP-21 certified cap mounted wiring block plus an integral 0.3 to 3 second fast discharge reactor module that dramatically exceeds UL/CSA mandated voltage discharge standards. They also include built-in protection from voltage transients and have a very long service lifetime.

 

All models are built into EASI's U-series of modular powder coated steel enclosures that can ship in either NEMA 1 or NEMA 3R configurations. EASI also offers the following upgrades to the U-series: a factory installed gasket and grommet upgrade to the NEMA 12 configuration, NEMA 7 and NEMA 9 explosion-proof enclosures, NEMA 4X corrosion proof enclosures, current sensing disconnects, internally mounted fusing, and LED indicator lights.

 

 

 

Passive Harmonic Correction Filters (PowerLiners)

PowerLiners meet the growing need to reduce the costs associated with today's non-linear electrical equipment. More AC to DC conversion equipment is being used in today's buildings from Variable Frequency Drivers (VFD's) to DC Drives, Rectified DC Power Systems, Welders, Robotics, and Arc Lighting. Harmonic current is becoming a predominant part of every business' electrical demand. The Passive Harmonic Reactive Power Correction System cancels a portion of this harmonic power normally drawn by these loads, thereby reducing kilowatt hour consumption, as well as any problems associated with harmonics inside your facility.


PowerLiners reduce the harmonic energy normally demanded by this equipment by cancelling a substantial portion of the fifth (5th) and seventh (7th) harmonic currents supplied to the load. This saves energy, reduces heat generation inside equipment, frees up new electrical capacity in the facility, and most importantly, produces direct kilowatt hour reduction on the electricity bill by reducing the alternating current distribution losses in a facility.

 

The Passive Harmonic Reactive Power Correction System does the following:

  • Extends the life of equipment
  • Reduces harmonics issues in the facility
  • Increases electrical capacity
  • Cools overheated lines and panels,
  • Lowers kilowatt consumption and demand
  • Improves the facility's power factor
  • Helps meet IEEE-519-1992 standards
  • Lasts for one hundred forty thousand (140,000) plus hours of service

We manufacture a complete range of low voltage, three-phase Passive Harmonic Reactive Power Correction Systems, in a stepped model range from 1.3 KVAR to 30 KVAR, with four voltage lines.  They are as follows: 200- 240V, 380-440V, 440-480V, and 600V three-phase, for both 50Hz and 60Hz applications.   KVAR requirements above 30 KVAR are available by simply paralleling multiple units.  All models use an advanced inert gas filled, dry polypropylene and self-healing film, single-mounting-bolt cylindrical capacitor style, which is manufactured in an ISO 9001 certified facility, and includes a CE IP-21 certified cap mounted wiring block plus an integral 0.3 to 3 second fast discharge reactor module that dramatically exceeds UL/CSA mandated voltage discharge standards.

Dynamic, Real-Time Reactive Power Compensating Units with Harmonic Filters (Elspec)

Elspecs are a fast response system that is used to compensate any variation in reactive power within one quarter of a cycle of the network. This is accomplished by the following methods:

 

Capacitor Switching
Our Elspec units switch capacitor groups on and off using state-of-the- art electronic switches. The connection and disconnection of capacitors occur precisely at zero-current crossings. This smooth connection avoids transient effects typically created by electromechanically switched power factor correction (PFC) systems, thus extending the life expectancy of the unit dramatically.

 

Fast and Accurate Measurements
The controller uses Fast Fourier Transform (FFT) analysis of all phases for each cycle. Power information, system status, and detailed logs of events are displayed on a large, backlit, LCD screen, or via communication.

 

Ideal PFC Control
Using exclusive automatic control algorithms and rapid electronic switching, total acquisition time (the complete compensation of reactive current) is achieved, typically, in ¼ cycle irrespective of the number of steps required. For 50Hz systems, this means a total acquisition time of 13.3 ms, and for 60Hz, that time is 4.0 ms. The power factor is controlled, very accurately, through an advanced open and closed-loop control and measuring system that uses information from all three-phases, as well as accounts for the effect of harmonics one (1) through sixty-three (63). Minimum, maximum, and average power factor modes, as well as threshold levels, can be selected for perfect compliance with specific network requirements.

 

SCAN Mode
A unit is equipped with a unique SCAN feature that protects capacitors from exploding and contributes to longer life expectancy by reducing over-current and minimizing capacitor heating. The electronic switching element connects one capacitor group simultaneously as another group is disconnected. This operation occurs every few seconds, engaging each capacitor group in turn, with total compensation unchanged. This results in mean current reduction due to the lower duty cycle, or the engagement time to cycle time. Couple this with the unique reactor design and temperature rise of the reactors is substantially reduced, as well as the potential for cabinet overheating being minimized.

 

Consistent Capacity
Conventional electromechanical capacitor banks suffer from an ongoing cumulative reduction in capacity due to the effect of transients during connection and disconnection. This can be especially detrimental in tuned and detuned electromechanically switched systems where changes in the ratio between the capacitors and reactors shift the resonant frequency. This scenario can cause resonance, which can cause extreme damage to equipment in the facility. Our unit prevents this scenario, resulting in longer system life, and lower maintenance costs.

 

 

 

EASI Optimizers

The EASI Optimizer is a "smart" micro-computer based energy saving device that can be easily installed on commercial hydronic and steam heating systems, central air conditioning systems, and commercial refrigeration units. In laboratory tests, conducted by independent testing laboratories, and in real world installations, the intelligent controller has delivered energy consumption savings of ten percent to thirty percent (10% - 30%) or more without affecting the temperature levels.

 

The intelligent controller reduces energy consumption by analyzing the demands and characteristics of the entire heating, air-conditioning, or refrigeration system, and dynamically modifying the burner or compressor cycle pattern. These new patterns result in less frequent and more efficient cycles, similar to highway driving versus stop-and-go driving. Unlike some other products, the intelligent controller is truly a "smart" product that does not require any programming and automatically compensates for load and seasonal changes, thus always providing optimal savings.

 

Air Conditioning and Refrigeration PROA (Frigi-Tech)

Polarized Refrigerant Oil Additive, or PROA, is a lubricant containing a napthenic oil base with a number of specially developed additives. PROAs contain two anti-oxidation and anti-wear systems that reduce friction, save energy, and extend equipment life. The primary system stays in solution and is triggered by temperature on a needed basis only. The secondary system is metal seeking and latches on to all the internal metal surfaces.

 

Polarized refrigerant oil additives have the following effects:

  • Quiets compressor noise
  • Increases cooling capacity
  • Reduces electricity consumption
  • Improves heat exchange by displacement of refrigeration oil buildup
  • Reduces friction, prevents oxidation, provides corrosion protection
  • Provides stabilized boundary lubrication protection during operation and startup
  • Improves the life of bearings, seals, and all compressor parts

Reduced friction improves the compressor's mechanical efficiency and lowers power consumption. The special additives displace oil buildup to improve coil heat transfer for the evaporator and condenser. This improved thermal efficiency, or heat duty, increases the unit's cooling capacity, thus allowing it to run fewer hours per day for the same amount of cooling.
