1 The Best Technology for the Application Educating the Specifier on Medical Air & Medical Vacuum Systems

2

3 Want to discuss the technologies Feel an educated specifier is the best business partner Often hear from end users they aren t sure who selected the pump. See where a technology is selected which is likely incorrect for the application

4 Codes NFPA 99: Health Care Facilities Complete rules for the safe application of electrical systems, gas and vacuum systems, and environmental systems, along with materials and emergency management practices. The 2015 edition has the most recent developments in medical equipment and processes as well as new methods to reduce fire, explosion, and electrical hazards.

5 Definition: Air & Vacuum Medical Air is life sustaining breathing air used by hospitals, surgery centers, dental facilities, outpatient clinics Applications include respirators and breathing tents. Medical Vacuum typically used for evacuation in surgical procedures found in same facilities as medical air Lab Air is normally a less stringent variation of medical air used in industrial and clinical laboratories for sterilizers, controlled experiments, and other laboratory processes. Lab Vacuum is normally a less stringent variation of medical vacuum used in industrial laboratories, clinical laboratories, universities, and health testing facilities.

6 What determines the Best Technology for the Application? The technology they ve always used? Cheapest price? Buddy who comes by once a month? Salesman that always says we re having a special this month? Today much is chosen by what is existing, what the specifier is most familiar, or what the MedGas Manufacturer recommends

7 Factors that determine the Best Technology for the Application What will the demand profile of the facility look like? Constant demand? Low/High Peaks What about sustainability of the facility? What is the maintenance practices? Are there energy considerations? What is the budget criteria, willing to invest?

8 Traditional Air Technologies Reciprocating Compressors Scroll Compressors Screw Compressors Liquid Ring Compressors

9 Reciprocating Compressors Traditional Piston Displacement Compressor incorporating Teflon Rings and oil-free operation Highly reliable and easily rebuilt Requires moderate level of maintenance and routine monitoring

10 Scroll Compressors Compression starts from the outside of the scroll and works toward delivery pressure at the center. Compression is accomplished by the orbiting scroll moving with in the fixed scroll. Highly reliable Low maintenance Quiet operation Air inlet Air Stationary scroll Low tolerance to running in reverse Orbiting scroll Air outlet

11 Oil-less Rotary Screw High Output for larger demands (30Hp+) Highly reliable Low maintenance, oil in gear chamber Quiet operation Available in Air/Water Cooled configurations

12 Liquid Ring Compressors Key. Considerations: Not used as much today Low Maintenance Water Quality critical to lower maintenance Water temperature critical to achievable Vacuum levels Utility cost of water Quiet Operation

13 Review of Air Technologies Technology Cost ($/CFM) Life Span (hours) Noise Maintenance Cost Energy Consumption (CFM/HP) Additional Considerations Reciprocating , db High 3.5 Scroll , dB Low 3.2 Screw ,000 69dB Medium 4.2 What is facility capabilities What is facility capabilities Environmental Considerations Liquid Ring , dB Low 4.2 Environmental Considerations Assumptions: Based upon equipment costs not installed cost Prices ONLY for like comparison of technologies Used 7 ½ Hp for comparison except 30Hp for Screw

14 Traditional Vacuum Technologies Dry Rotary Vane Lubricated Rotary Vane Contactless Claw Liquid Ring

15 Dry Rotary Vane Technology Key Considerations: Medium Maintenance Required on Vanes Depth of Vacuum a factor Quiet Operation

16 Lubricated Rotary Vane Technology Key Considerations: Lower Maintenance Required on Vanes Deeper Vacuum Levels achieved Affordable Pump Relatively Quiet Operation Not allowed as WAGD evac pump by code Replace Oil Every 1,000 hrs.

17 Contactless Claw Technology Key Considerations: Low Maintenance Higher Cost of Equipment Gear Oil Replacement Good candidate for VFD (energy efficiency alternative) Vacuum Level considerations 24 Hg Noise Considerations WAGD evac pump if Fomblin is utilized

18 Liquid Ring Technology Key Considerations: Low Maintenance Water Quality critical to lower maintenance Utility cost of water Quiet Operation

19 Review of Vacuum Technologies Technology Cost ($/CFM) Life Span (hours) Noise Maintenance Cost Energy Consumption (CFM/HP) Additional Considerations Dry Vane , dB High 4.3 Lube Vane , dB Medium 6.9 Contactless Claw ,000 85dB Low 8.7 Liquid Ring , dB Low 4.2 Altitude considerations Good choice for deeper Vacuum Altitude considerations Good choice for deeper Vacuum Assumptions: Based upon equipment costs not installed cost Prices ONLY for comparison of technologies Used 7 ½ Hp for comparison

20 Key Considerations: Only one VFD per system Inherent soft start/stop, easier on mechanical system Fail-safe backup schema 25Hz min run frequency for cooling reasons

21 Amps Medical Vacuum VFD Controls (Claw) VFD Frequency vs. Amps HP 5.4 HP 6.4 HP 7.5 HP 8.7 HP 15 HP 4 20 Hz 30 Hz 40 Hz 50 Hz 60 Hz Frequency

22 DBA Level Claw Vacuum VFD Controls (Claw) VFD DBA vs. Frequency HP 5.4 HP 6.4 HP 7.5 HP 8.7 HP Hz 30 Hz 40 Hz 50 Hz 60 Hz Frequency

23 Environmental Considerations Often should consider the utility cost associated with some selections Consider the noise/vibration in applications where worker productivity can be an issue Seismic considerations of pumps and compressors
