The Heart of EMAX Rotary Screw:
The Airend is the most important part of your compressor, it is the heart of the machine that actually compresses the air. That is why here at, Emax Compressor we use only the best German and Finland name brand airends. Most airends are only good for up to 40,000 hours and then they need a complete overhaul, with our airends they are good for 70,000 running hours as long as the unit is maintenance routinely and the correct oil is used. EMAX Compressor Gives you a 10 year warranty on all their airends!
All Emax Air Rotary Screw air compressors are equipped with these state of the art screw airend compressors manufactured in Germany and Finland. These airends have precision-aligned back to back tapped roller bearings with close tolerances guarantee long life cycles and outstanding reliability. Each air end is tested to meet consistent high quality standards.
Premium Industrial Motors
We use only premium industrial name brand motors to run our compressors. Emax 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 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!
Save that energy!!
Since the motors consume a majority of the energy produced then the controls you put on the motor become an increase importance. When a motor starts at full load voltage it causes a voltage sag on the power system, it can cause shock damage creating long term damage to your motor. You can save 25-70% on energy by using motor controls or variable frequency drives. Our entire rotary screw line has the ability to have variable frequency drives installed in them. We use Schneider Altivar71 Brand drives that carry a 5 year warranty. Schneider Electric has been around since 1981.
Control: When a motor is started it takes as much as 8 times the full load motor current to start. An adjustable speed drive can take on 50-70% of that motor full load current by starting the motor at zero frequency and voltage, it works by magnetizing the motor winding’s and builds the frequency and voltage slowly, in short the variable speed drive starts as a zero speed and accelerates smoothly up to your settings.Programmable controls allow for adjustable operating speeds as well. These Schneider Altivar71 variable speed drives can be programmed to run at specific speeds, to stop at a specific position, they are even capable of applying a specific amount of torque. The ability to control these minimizes mechanical and electrical stress on the entire unit. Lower Power Demand: Many power companies will offer rebates when running your system with a variable speed drive. in most cases the system will pay for its self over time, even in as in short of time as one year. Because some power companies are limited then they put demand factors on industrial customers, so they charge you for surges in your power that may be robbing other customers during peak hours. The variable speed drive eliminates those surges. We have provided you with an example of ht average energy savings from APE Energy. use the link to see the potential savings. When 60 cycles of electricity are inducted into the electric motor, the motor RPM is a low 1750, however the Variable speed inverted drive will change the 60HZ to 60 Cycles of electricity from 60 cycles down to 18 cycles, depending on the pressure, The whole ides of energy savings with this unit is to lower the cycles, the lower the amp draw coming from your electric motor.The electricity amp draw that an electric motor is using determines what your electric bill is, so the lower the amp draw the lower your bill will be!
Programmable Logistic Controller
These rotarys are 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 EMAX 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 Emax 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 evening 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.
The BEST Warranty Around!
Emax Compressor backs all their compressors with the best warranty in the industry. Emax Compressor gives their Rotary screw Pump a full 10 year warranty, 5 year on the motor and all other components ! The warranty is NOT pro-rated. We cover labor for the first 12 months for major repairs.With our warranty we don’t ask you to buy a service plan or extended warranty, we just ask that you purchase and use our oil and filters. This ensures the correct oil with the specs needed to run our pumps is used. Our trained service and support team is ready if you ever need them and we carry a full line of new replacement parts.
