1. 1 an eye that never blinks

2. 2 Refrigerant Monitoring  Checking for excess moisture in the refrigerant  Checking for low charge or loss of refrigerant

3. 3 Moisture  Excess moisture can lead to  acid formation which eats away at refrigeration equipment.  icing which can cause restrictions in valves and ports (reducing efficiency).

4. 4 Low or Lost Refrigerant  Low refrigerant levels can lead to  extensive equipment failure  to labor- intensive repairs and replacement of expensive system components.  product spoilage and loss in cooler/freezer systems.

5. 5 Why Monitor Refrigerant?  Consider the economic incentives.  Consider the environmental impact (for its own sake and for the regulations).  Consider our professional responsibility to protect the facility and its occupants.

6. 6 Typical Monitoring  Direct—Probes and float switches in level columns and tanks, with connected control panels, measure refrigerant levels directly.  Indirect—Gas monitors and connected control panels measure the atmospheric result of loss.

7. 7 Typical Monitoring  Both of these methods are costly, particularly in small box operations (restaurants, convenience stores, etc.).  In the case of indirect measurements, serious loss occurs before alarms are made and repairs initiated.

8. 8 Site Glass  Simple  Economical  Informative

9. 9 Site Glass  But, it requires a visual inspection  Typically only inspected AFTER there has been a failure in the system

10. 10 KMC Innovation  A 24/7 eye on refrigeration site glass (an eye that never blinks).

11. 11 What is FirstWatch?  A patented, optical device designed for use with the Sporlan See-All ® site glass.  Like the site glass itself, a simple, economical, and informative service tool.  A non-invasive and accurate measuring method for both moisture and low refrigerant.

12. 12 FirstWatch—Up-close FirstWatch site glass monitor Refrigeration Alarm Monitor (optional)

13. 13 FirstWatch Applications  Chiller/mechanical rooms

14. 14 FirstWatch Applications  Supermarket/Convenience store display cases and freezers

15. 15 FirstWatch Applications  Roof-top air conditioning units

16. 16 Key Features—Simplicity  Ease-of-installation  Mount (snap on)  Intuitive Operation  Wire (4) 24 VDC Power Ground Moisture (0-5 VDC proportional) Flash Gas (0-5 VDC proportional)

17. 17 Key Features—Flexibility  Connect FirstWatch to any conventional Building Automation System.  Or, for standalone applications, add the optional RAM (featuring audible and visual alarming).

18. 18 RAM Flexibility  Baseline set  Alarm level set  Delays  Muting of audible alarms

19. 19 Key Features—Cost Effectiveness  List Price of FirstWatch is only $499.  List price for the optional RAM is just $250.

20. 20 Key Features—Design  This patented design achieved compliance with the Environmental Testing Verification, an EPA program.  Polymer housing is water and dust resistant and flame-retardant.

21. 21 Key Features—Accuracy  FirstWatch makes its reporting (to BAS or RAM) through the proportional amplitude of the respective 5 volt signals.  In the case of flash gas, indicative of low charge or refrigerant loss, FirstWatch can ignore normal transient and momentary flash.  In addition to refrigerant loss, FirstWatch can detect the flash gas that can occur due to dirty coils or other system malfunctions.

24. 24 Other Benefits  Offers reporting and trending (when tied to BAS)  Can help evaluate the effectiveness of service personnel  Was the system charged properly?  Was moisture allowed into the system?  Was the system evacuated?  Was the drier replaced?  Were leaks properly repaired?

25. 25 Considerations  First Watch is dependent upon the proper installation of the site glass.  In addition, the site glass should be clean.  When used with certain chiller types, FirstWatch should be tied to a BAS to compensate for start-up and cycle turbulence.

26. 26 Summary  Non-invasive  Continuous monitoring (never blinks)  Early detection  Helps prevent product loss or equipment failure.  Simple, flexible, cost-effective, & accurate
