The Polar Air Difference

Save that energy!!

3 Benefits of Variable Speed Drive by Schneider:

1.  Starting Peak Demand SavingsA standard speed unit can be up to 7xs greater to start up whereas with a variable speed that isn’t the case.  Variable speed gradually increases motor speed ramping the startup RPM slowly. Companies that are not on Peak Demand Meter suffer immensely on their Demand electric bill charges.

2.       Running Demand Savings. Polar Air by Eaton Compressor has a quick and easy adjustable pressure setting in the PLC controller. The pressure ranges from 70 PSI to 145 PSI. Our factory setting falls in the 120 to 145 PSI range. The motor will run the pump at full speed after start-up to low-pressure PLC setting of 125 PSI. Once 125 PSI is achieved then, as each PSI increase from 125 PSI to 145 PSI, the motor will reduce its speed. After full PSI is reached then the electric motor will enter a full idle mode. Our units have a cfm turn down of 80% full cfm. Our 60 HP cfm range is from 259 cfm (high side) and 51.8 cfm (low side). This system works off your air demand saving energy in a big way.

3.  Wear and Tear Savings. Variable speed compressors save wear and tear on the pump and motor bearings. The constant reduction in the motor speeds reduces the friction on the bearing loads which will increase the motor and rotary screw pump life cycle.

The Heart of your Rotary Screw:  Energy Facts - Rotary Screw Pumps

Tolerances and Rotor Profile Designs.  Components used to produce a rotary screw compressor pump are very important in regards to true energy savings.  Tamrotor by Gardner Denver E12G Male/Female Rotors and Cylinder Cases are machined to highest precision tolerances.  These high tolerance standards reduce internal pump leak paths and yield high scfm performance.  A lot of foreign rotary screw compressors talk a big game but cannot meet the precision tolerance standards in their rotary compressor performance.  This is because of outdated antiquated machinery and outdated compressor designs.  GD patented rotor designs yield the highest performance in KW to CFM output performance.  Making pumps with high-efficiency standard’s costs a lot more to produce in time and labor costs.  GD Finland is a top 5 world compressor component manufacturer with over 150 years of know-how experience in the compressor industry.  They are continuously increasing performance, staying ahead of the competition and saving energy.

 100,000 hr Bearing Performance. Most rotary screw compressors on the market are only good for 20,000 to 40,000-hour pump bearing life spans.  GD pumps are good up to 100,000 hours on the pump bearing life. Lower bearing quality and bearing designs, in turn, yield lower rotary screw pump life and low compressor performance over time.

Gear Driven Direct Drive Pumps.  Because of the true 100% alignment and load reduction of the pump and motor bearings, GD gear driven pumps save from 1-2% on energy over a belt driven pump.  Units without gearboxes have no flexibility in changing higher pressure ranges.  For every 10 PSI increase, it puts a 5% greater load on the electric drive motor.  Our units are gear set for 145 PSI ranges.  If a customer wants a higher PSI of 175, it requires a reduction in pump speed to reduce the load on the drive motor.  Our pumps can be changed to different gear ratios for customer wanting a pressure increase, while units without a gearbox in place cannot change to a higher psi without changing the whole pump.  This can be a huge cost change.

Rotary Screw VSD/VFD Advantage Option over a Rotary Vane Compressor   A rotary screw compressor is the most efficient in variable speed applications.  Our units can vary in the motor rpm as much as an 80% reduction.  Rotary screw units do not depend on centrifugal force to operate the compressor air like a vane type compressor.   A vane type compressor depends on the high rpm to slide the cylinder vanes to make compression.   When pump speeds are reduced a sliding vane pump loses rpm and its centrifugal force to operate yielding more leak paths and lower performance at lower pump speeds. Vane-style compressors also lose efficiency in higher PSI ranges.  A rotary screw pump has a fixed rotor and yields more cfm efficiency at higher pressure ranges up to 218 PSI if needed.

    Premium Industrial Motors

    We use only premium industrial name brand motors to run our compressors. Polar air uses only low 1750 RPM motors. We have chosen motors that come with the best certificates and quality assurances so we know that you are getting the best as well! We use High-Efficiency inverter variable speed duty motors constructed with superior materials, higher service factors, longer bearing lives, lower waste- heat output and less vibration. We also pass the motor warranty on to you for a full 5 year on single phase and a full 10 year on 3 phase!!

    The US Motor Corp Motors are made of heavy duty cast iron construction. We use TEFC (Total enclosed fan cooled ), meaning the motor is dust tight and doesn't allow outside air in, it instead uses the fan to blow air over the frame of the motor to cool it. These motors all have copper bar rotors, this technology dates back to the 1920's. Copper helps improve the electrical energy efficiency of the motor because of its density and ability to transfer energy. Many motors are made of aluminum rotors, these inefficient electric motors waste electrical energy and therefore cost more to operate. Copper reduces the energy loss by 15-20% compared to aluminum. Inefficient motors cause many issues, they waste more energy, in turn increasing electrical demand, thus increasing your electrical cost. Copper generates less heat and thermal stress, therefore, enabling longer life to the motor then aluminum.

    VMC Inlet Valve

      As mention earlier the airend is the heart of the compressor but is does not work alone. The outside air is brought in and filtered before it hits the inlet valve to ensure it is receiving clean air.  The inlet valve regulates the amount of air that is sucked in by the rotary screw. When the valve is in a loaded state it is compressing air and pumping it into the airend, when it is in an unloaded state is shuts off the air supply, so the motor and screw air turning but not taking in air. Therefore not pumping any air to the system. Our VMC inlet valves have a counter weight which ensures fast, tight close when the air flow is reversed. This load and unload system has greater energy savings as well. When running the compressor in the unloaded state it allows the compressor to store more air than is being used., a storage tank must be used in this case.  The larger the storage tank the longer the no load cycle time, the greater the savings. This unit will save you hundreds on your electric bill because under start up the modulator valve is completely closed. This closes the air off to the screw intake making low load under start up. After the unit gets started, it has a 12-secound time delay. this allows the unit to get running fro 12 seconds before it starts pumping air. This makes no load starting and will save your magnetic starter contractor and motor because of low amp draw.  VMC was established in the 1970's      

    Programmable Logistic Controller    

    7.5hp air compressor by Eaton Compressor is controlled by a user-friendly Logika PLC (Programmable Logistic Controller). This controller makes this unit bullet proof. These controllers have may many features that are extremely user-friendly and easy to use. Here are some of its key features.

      variable speed ready to Control the speed of the motor

      Adjust Pressure - to what pressure range you need. This can be set by the customer, this unit has a shutdown in case the unit goes over pressure. the unit has a maximum pressure setting - the computer will sense that it is going over pressure and will shut down.

      Low Oil Shutdown - if the controller senses that the unit is going into high temperature it will shut it down. It will also shut down if the compressor runs low on oil.

      Reverse Fault - the controller will control when the unit is wired up if it is running backwards, it will sense a reverse rotation fault and shut the unit down

      High Voltage Fault - if the voltage is 15% over the power supply voltage rated on the Polar compressor data plate, the unit will shut down. Also if the voltage is 15% under it will shut is down as well.

      Over AMP Shut down - if the motor is pulling to many amps it will shut down. You can check the amp draw of the electric motor as it is running and also on the exhaust fan motor

      Clock and Date - Built in Clock and Date to help keep track of preventative maintenance services.

      Light - Has a built in light for dark locations.

      Parameters- has a maintenance parameter system to create and maintain the parameter and control information.

      Hour meter - Built in hour meter to keep track of the running hour on the machine.

      Fault History -The PLC stores history if the unit shuts down, information on why it shut down is stored

      Maintenance Service - Keeps track of when to change the air filter, oil filter and the coalescing filter along with the unit needs greased. When they need changed the PLC will sound an alarm.After changing you simply reset that filter back to zero and start the maintenance tracker again.

      Air Differential Control- with differential control you have a wide range of pressure settings. You can take the kick-in pressure all the way down to 100 PSI and all the way up to 145 PSI. You can adjust this range anywhere in between. You can also set the high end down to a lower pressure where ever the customer unit pressure is desired. The Polar Compressor is factory set at 120 kick in and 145 kick out. The lower the pressure the higher CFM and the more hours you will get on your screw compressor, so keep the pressure as low as possible.

      Built in Timer -will sense when the unit is not being used for a period of 20 minutes under no load, this will shut down the machine automatically so it will restart as air pressure goes down to the kick- in set point.

      On- line demand - this setting is made for high volume and will bypass the automatic kick-off mode. It allows the unit to keep running on continuous run mode for high air demand.

      Warranty - These PLC's carry a 5 year warranty

      Daily / weekly Schedule - This unit can be programmed to start in the morning, can shuts its self at lunch if needed and can turn itself in the even as well, or when ever needed.

      Self Start - if the power is lost this unit will automatically restart itself, this eliminates a maintenance crew to have to restart after the shut down.

      Master Slave - this controller can switch from one unit to the other and maintain the same use of hours, it can adjust the pressure to be the lead or the lag unit.


       Premium Mann Filters

      Filters help protect the compressor from wear and damage. It is the most inexpensive way to prevent possible costly repairs. It is vital that these filters are replaced and inspected on a routine basis, the timing is important as is reduces the chances of component and airend contamination. It can decrease the energy efficiency of your machine as well if not done.  Because we know the importance we use only genuine Mann Filters. These Filters are not exclusive to us therefore after your warranty is up you will still be able to find these parts. Mann Filters are made with exceptional quality and provide optimum protection against harmful elements. Our rotarys also havead Pre-Filtration on the outside of the cabinets. Although this is an upgraded feature it is one that is well worth the cost to protect the life of your compressor. Even in environments that are not that dirty the build up over time can be damaging to the system and seriously impact the performance. ask about adding a Pre-filter kit to your system to save even more money!
