The technology that delivers your savings

ELECTRICITY

The approach taken to gain electricity efficiency in existing facilities is to install power treatment technologies to the individual loads in a facility, and where needed, to install active or passive power quality correction at either the individual loads, individual branch circuits, or the master service entrance. The electricity savings from the power treatment technologies originates from these concepts:

Power Factor Correction

Power Factor affects every operation with a 3-phase AC electrical supply to some degree or other. Quite simply, Power Factor is a measure of how efficiently electrical power is consumed. The ideal Power Factor is unity, or one. Anything less than one, (or 100% efficiency), means that extra power is required to achieve the actual task at hand. This extra power is known as Reactive Power, which unfortunately is necessary to provide a magnetising effect required by motors and other inductive loads to perform their desired functions. However, Reactive Power can also be interpreted as watt-less, magnetising or wasted power and an extra burden on the electricity supply.

Power Factor Correction is the term given to a technology that aims to restore Power Factor to as close to unity as is economically viable. This is normally achieved by the addition of capacitors to the electrical network which provide or compensate for the Reactive Power demand of the inductive load, and thus reduce the burden on the supply.

Benefits of Power Factor Correction:
• Power consumption reduced
• Extra kVA availability from the existing supply
• Electricity bills reduced
• Transformer & distribution equipment I2R losses reduced
• Electrical energy efficiency improved
• Minimised voltage drop in long cables

Lighting Correction

In order to achieving greater lighting efficiencies homes and businesses have turned to fluorescent and HID lighting. While this lighting is more efficient than incandescent lighting, it is also true that neither fluorescent nor HID’s are maximally efficient when connected to standard, sinusoidal waveform AC power.

The entire PGS line of special purpose of waveform modification based lighting controllers significantly reduce total energy consumed by these lighting fixtures, yet can achieve significant operating cost savings without reducing visible spectrum light output.

Secondly, all lighting controller technologies have been designed to suppress or trap broadband harmonic content from the load side of the device, therefore adding to the system’s cascade effect of both improved overall efficiency and improved facility power quality.

OIL & GAS

The PGS oil and gas systems are advanced, micro-processor based boiler management and warm air control systems which utilise and combine time proven techniques and modern data processing to intelligently control central heating boilers/burners and reduce energy consumption and CO2 emissions.

The systems use Variable Thermal Response to intelligently manage the boiler and ensure it economically and efficiently meets the performance requirements of the heating system. It takes account of all changeable factors including level of demand, boiler flow and return temperatures, external and internal temperatures. Other features include temperature compensation, on/off optimisation, frost protection, night time controls, hot water priority and temperature control, multi boiler step control and sequencing, digital programming, security coding and bypass facility.

PGS TECHNOLOGIES

PGS Liner™

Reactive Power Correction

A waste-to-energy technology that eliminates the non-work producing portion of your electricity, resulting in lower electric bills, higher performance and longer life for electric motors and other magnetically driven AC electrical equipment.

Without operating power reductions or loss of RPM the PGS Liner™ recycles wasted reactive current, generating enough savings to pay for itself 10-15 times over during its normal lifespan, as well as greatly improving the operating efficiency of the treated load. By reducing heat losses and improving voltages in both the electrical supply circuit and the treated load, the PGS Liner™ decreases all associated costs - maintenance, repair and replacement, loss of production due to failure, and actual billed electricity costs.

IllumiLiner 20™

IllumiLiner 20™ Active Lighting Controller

The IllumiLiner™ unit is entirely solid-state with microprocessors that continually monitor and modify the AC sine wave. The IllumiLiner™ controls entire circuits of lighting from the lighting panel, providing circuit-by-circuit flexibility and a very high rate of return on investment. The well ventilated cabinet is made of sturdy, heavy gauge metal with a mar-resistant, epoxy finish to withstand even brutal industrial environments. Being a superior alternative to 'de-lamping' in order to save energy, the IllumiLiner™ improves the lighting's performance to voltage, and provides for controllable distribution of illumination.

The IllumiLiner™ automatically adjusts itself to your lighting system voltage. The units are configured at installation for the type of lighting being treated, and then provide exactly the real time correction appropriate for magnetic or electronic ballast fluorescent fixtures; metal halide, sodium, or mercury vapour high intensity discharge fixtures; or incandescent or quartz lighting systems.

EURO™ Family

EURO™, EuroLiner™, EuroLUX™, and EuroTrio™

The EURO™ line of lighting savings products is built to provide predictable lighting cost savings with either electronic ballast fluorescent or HID lighting.

Originally developed in response to application needs on unusual European style fluorescent ballasts, the EURO™ line of products has grown to be a workhorse in PGS's lighting program. By using variable levels of inductance to control current to the lights, none of the EURO™ line of products introduces harmonics or adds any irregularity to the AC waveform. In fact, by including specific filtering circuitry, all of our EURO™ units actually reduce facility harmonics.

The EURO™ 3500 is a versatile multi-setting product used in higher amperage circuits requiring a rugged and dependable solution, and where specific concerns about facility harmonics exist. The EURO™ 3500 includes an automatic start-up time delay system for permitting higher savings selections not to interfere with your lighting warm-up requirements. Available for 277 volts.

The EuroLiner™ is a simplified version of our EURO™ 3500. Designed to be used on circuits where measured load amperage is less than that mandating the 35 amp capacity of the larger product. Available in 8 amp and 16 amp versions for any voltage from 100V to 347V, the EuroLiner™ is our most widely implemented product for electronic ballast fluorescent and non-auto regulated ballast HID lighting systems. The 3-phase EuroTrio™ comes in 30 to 150 amp versions for 200 to 480 volts.

The EuroLUX™ is a nominal 20 ampere unit built specifically for harmonics challenged facilities, or where compliance with the IEE-519-1992 international harmonics standard is a goal of the PGS project being installed. By combining the function of our EURO™ design with a 3rd order tuned harmonic filter section, the EuroLUX™ both saves money on electricity and reduces harmonics.

The EURO™ Family benefits:

• Modernises your lighting without requiring new bulbs, ballasts, or fixtures
• Uses a completely passive non-harmonics producing savings method
• Can reduce facility harmonics and contribute to IEEE- 519-1992 compliance
• Can easily be tailored to any size lighting circuit, the EuroTrio™ is for 3-phase circuits
• Cools your bulbs and ballasts, increasing useful lifetimes and decreasing maintenance costs
• Reduces air conditioning costs by lessening the heat load added by your lights


Final Condenser™

HVAC Fluid Heat Correction

Increase the performance and cooling capacity of air conditioning and refrigeration units up to 35% while adding to the life of your compressors.

Air conditioning and refrigeration units that are air cooled can benefit dramatically from the use of the PGS Final Condenser™ which pre-cools and sub-cools the refrigerant before entering the unit's evaporator.

All air cooled systems have a condensing unit whose purpose is to cool the hot gas coming from the compressor into a cold liquid. This cold liquid is then sent on to the evaporator to do the cooling. The cooler the gas is to begin with, the less heat the condenser must dissipate, and the more efficient the system will operate. Pre-cooling dramatically improves the condenser's ability to make the liquid colder, making the evaporator colder, which turns off the compressor sooner, saving you energy dollars. Additionally, sub-cooling eliminates flash gas, further cooling the evaporator. Because there is colder liquid and cooler gas circulating in the system, head pressure is less and the compressor doesn't work as hard, saving you additional energy dollars.

Reduced head pressure and sub-cooling additionally create an extra cooling capacity which could possibly eliminate the need for additional or larger compressors.

TVSS™

Transient Voltage Surge Suppressor

Protects sensitive, electronic equipment from voltage transients that cause continual stress and degradation of microprocessor circuitry that contribute to shortening the life of motors and lighting.

The PGS TVSS™ provides an instantaneous response to voltage spikes that are greater than line voltage, dissipating the surge to ground before reaching your equipment to cause expensive performance degradation or damage.
What you can't see can hurt your equipment and computers. Momentary surges in line voltage frequently occur and can exceed several thousand volts RMS. No matter how brief in duration, these surges can shorten the life of motors and lighting, plus cause severe damage to computers and other microprocessor based equipment.


The PGS Industrial Voltage Surge Suppressor is designed for quick and easy installation at electrical panels and safety switches, or directly at the load. Its instant response to voltage spikes and cost effectiveness of operation make it the logical choice and your first line of defence in combating transient voltage surges.
