3 Ensuring a Rotary Screw Compressor is Right for Your Customer. In deciding upon a new or replacement Compressor Unit, there are many factors that come into play to ensure that your Customer is purchasing the correct Unit. These factors, some of which are indicated below, will determine both the type (Piston or Rotary Screw) and the Horse Power of the Unit. And though the Customer may have an idea as to what he wants based on any one factor, other factors may adjust the decision to a more suitable alternative. Price. Generally speaking, the initial price of a Rotary Screw Unit is more than a comparable Piston Unit. For example, if we compare 5 HP Tank Mounted Compressors c/w () 0 Micron Filter and a 60 CFM Refrigerated Air Dryer: Rotary Screw Unit: Piston Unit: Model: Order Entry No.: List Price: Model: Description: List Price: C5TD-69 S $ 4,56.00 VAV MS 5 HP HDI Unit $ 7, SAF-C-64 Canister $ 99.3 SAF-S-64 0 Micron Filter Element $ 4.25 ASD CFM Refrigerated Dryer $ 2, Total: $ 0,83.9 Installation: Rotary Screw Compressors ingest great amounts of air for both cooling and compression, and have internal Fans to keep the interior of the Cabinet relatively cool. Unless the Unit is installed in a large area where the air temperature is between 0 C (50 F) and 40 C (04 F) and the quality of air is clean, you may consider both intake and exhaust ducting. Piston Units are somewhat more forgiving in this regard. Cooling is achieved with the Pump Flywheel, so you must ensure there is a minimum of 0.5 meter (8 ) between the Beltguard and any wall, obstruction, etc. Maintenance: Though regular maintenance on both types of Units can be done by the Customer, if they are not mechanically inclined, they may wish to have a Service Technician familiar with Compressor Units complete the work. Using the 5 HP Unit as an example, and suggesting that the Unit be run 2000 per year, suggested costs incurred (less labour) for a two year period would be as follows: Rotary Screw Unit: Piston Unit: : Part No.: Description: List Price: : Part No.: Description: List Price: MK-C Hr Maint Kit $ MK Hr Maint Kit $ SAF-S-64 0 Mic. Filter Element $ SAF-S-64 0 Mic. Filter Element $ Total: $ Total: $ Please note that the above costs reflect the regular maintenance, and do not include the rebuilding of various assemblies that must be done from time to time. Duty Cycles. As indicated on Page 4, Rotary Screw Compressors have the ability to run almost 00% duty cycle for close to 24 hours a day, whereas an HDI Piston Unit can run up to a 75 to 80% duty cycle, this based on an 8 hour a day operation. This being said, having a Compressor run at a very limited duty cycle is not advisable, as condensation will collect with the oil, potentially causing issues and/or damage to the Unit

4 Comparison Between Rotary Screw and HDI Piston Units. DV Systems offers a full line of Rotary Screw Compressor Units, from the 5 HP B Series up to the 00 HP K Series. Rotary Screw Compressors are primarily used where there is a fairly steady air demand, the Units being able to operate at a relatively high duty cycle relative to a Piston Compressor. As well, the DV Systems Rotary Screw Units are enclosed in a Cabinet, making them quieter than a comparable Piston Unit. This is often a Customer s reason for purchasing a Screw Unit. As a Compressor Unit is a long term investment as it will last for many years, you must assist the Customer in purchasing the correct Unit, be it Rotary Screw or Piston, which best suits his air requirements. As well, though under-sizing a Unit may have adverse affects on the Customer s production, over-sizing a Unit is also not advisable. Noted below is a brief comparison of Rotary Screw and Piston (or commonly called Reciprocating ) Compressor Units.

The chart above reflects Rotary Screw Units and Heavy Duty Industrial Units only, the HDI Units being the closest Piston Unit equivalent to the Screw Units. 2. The Approximate HP/CFM rating is simply an average of all of the available Units. Actual Unit figures may vary. 3. The 5 Year (total) Rotary Screw Air End Warranty is available only if the Customer registers their Compressor Unit with DV Systems (this done by returning their completed warranty registration), uses only DV parts and Kits in the maintenance of the Unit, and maintains the Unit according to the appropriate DV Maintenance Schedule as indicated in the manual accompanying the Unit. 4. The 7 Year (total) HDI Pump Warranty is available only if the Customer registers their Compressor Unit with DV Systems, uses only DV parts and Kits in the maintenance of the Unit, and maintains the Unit according to the appropriate DV Maintenance Schedule as indicated in the manual accompanying the Unit. 5. The 5 Year (total) Motor Warranty applies only to 3 phase Motors and is available only if the Customer registers their Compressor Unit with DV Systems. The first year of the warranty includes parts and labour, the remaining 4 years parts only

5 Variable Speed Drive Air Compressor Units. The purchase of a Compressor is only a small portion of the overall cost of having a compressed air system. As shown in the chart at right, the initial purchase price of a Compressor is a very small percentage of the overall cost of the system, energy cost being by far the greatest portion. Rotary Screw Compressors are generally suited to applications where there is a fairly steady demand for compressed air. They can be run at close to 00% duty cycle and can therefore be more tailored to suit your actual air demand, as opposed to a Piston Compressor which, when run over an 8 hour day, has a maximum duty cycle of approximately 75%. There are several types of Rotary Screw Compressors available, these including the following: Modulating Compressor: The Compressor Motor and Air End run continually at full speed, but the Intake Valve opens and closes partially to accommodate changes in air demand. Load/Unload Compressor: The Unit operates similar to a Piston Compressor in that an internal Pressure Switch (Transducer) regulates the Unit. When the Unit loads and reaches maximum pressure, it idles or unloads (runs but does not compress air) until either a) the system pressure has dropped and the Unit is required to load once again, or b) the Unit shuts down. Variable Speed Compressor: The Unit runs similar in principle to the Load/Unload Unit, but it is able to run at slower speeds to match differing air demands through the day. The energy consumption when running slower is also decreased. A Screw Compressor coupled with an internal Variable Speed Drive ( VSD or sometimes termed a Variable Frequency Drive VFD ) can handle the constant loads for an extended period of time, running at close to a 00% duty cycle, but it can also be run at slower speeds to accommodate lower air demands at other times of the day. Variable speed drives can reduce the overall energy costs associated with operating the Compressor Unit by simply controlling the speed of the Motor and Air End to match consumption. The chart at right indicates a 25% savings for a VSD Unit compared to a Modulating or Load/Unload Unit. The Chart below gives an indication of energy costs for the various types of Screw Compressors. Costs are based on a 00 HP Unit operating 2 shifts per day. % Load Modulating Type of Rotary Screw Compressors Load/Unload with Gal/CFM Tank Load/Unload with 0 Gal/CFM Tank Variable Speed Drive 00% $ 36,30. $ 36,30. $ 36,30. $ 36, % $ 33,420. $ 34,680. $ 29,350. $ 27, % $ 32,330. $ 33,240. $ 27,820. $ 23, % $ 30,70. $ 3,070. $ 24,200. $ 8, % $ 28,000. $ 24,930. $ 6,800. $ 9,030. 0% $ 26,370. $ 6,620. $,740. $ 3,60.

8 B Series 0 HP Rotary Screw Air Compressor Units. The B0 Rotary Screw Compressor Units employ a Variable Speed Drive (or VSD ) to constantly match the Unit output and energy use with the air demand. As the air demand changes, the VSD adjusts the Motor speed to maximize energy efficiency. The VSD also starts the Unit by increasing the Motor speed gradually, this eliminating the in-rush current spikes (and its associated energy cost) at start-up. Please refer to Page 4 of this manual for further information concerning the advantages of purchasing a Unit with a Variable Speed Drive.

11 D Series 20 HP Rotary Screw Air Compressor Units. The D20 Rotary Screw Compressor Units can be purchased with or without a Variable Speed Drive (or VSD ) which constantly matches the Unit output and energy use with the air demand.
