TRI-DEK® 3/67THE BUDGET STRETCHER

Eliminates BypassKeeps Coils CleanSaves EnergyMold/Moisture ResistantReduced Filter Failure

Tri-Dek 3/67 2-Ply Panel and Link Filters offer the solution you need for better efficiency and helps to relieve the increased pressures on your budget.

ELIMINATES BYPASSTraditional cardboard framed filters allow dirty, unfiltered air to pass around the filter causing contamination on coils and the HVAC duct as well as allowing contaminates into the building. Studies have documented that even a thin film on the coils can have a huge impact on energy consumption - up to a 37% increase. In addition to the energy savings the contaminant in the HVAC conveyance system can cause long term systemic problems that can be very expensive to abate.

MOLD/MOISTURE RESISTANTCardboard framed filters are vulnerable to the effects of moisture, even if they have been treated. Moisture can cause premature filter failure - the frame becomes wet and will buckle under the pressure of the system (as pictured top left). If the frame remains wet and conditions are correct mold and other microbials can easily grow on the filter media and frame - see photo lower left. The TRI-DEK 3/67 uses no cardboard but relies on an internal wire ring for support, this wire ring is sealed between two layers of synthetic media. This creates a filter resistant to moisture/mold that will save you money by reducing costly abatement.

Longer Service LifeDepth Loading MediaEnergy SavingsReduced Shipping/StorageReduced Labor

LONGER SERVICE LIFETRI-DEK offers a unique depth loading media that allows the filter to manage the dirt. Most filters are constructed of media that surface loads reducing their service life and causing high resistance to airflow across the filter after a short period of time. This high resistance can cause dramatic increases in the related energy cost. TRI-DEKʼs media experiences a less dramatic increase in the resistance since it depth loads. TRI-DEK media is composed of different deniers of media allowing for larger particles to be captured on the first layer and smaller particles are filtered as the air passes through the filter media. Depth loading reduces energy cost and allows for a longer service life. The longer service life saves money in a variety of ways ... on the number of filters you need to buy per year, labor cost, disposal cost, etc.

REDUCED SHIPPING/STORAGETRI-DEK is packaged 24 per case rather than 10 or 12 per case. This can safe additional money as reduced storage space is needed and can reduce freight cost by up to 50%. Another huge benefit is reducing the number of trips to and from the air handler the HVAC technician has to make transporting filters.

Drawing Organization

The Primary Organization And Order Of The Project Drawing Set Is Determined By The Trade. The PrefaceLetter(s) Of The Drawing Name Indicates The Trade.

1. General (G Series)2. Mechanical (M Series)3. Electrical (E Series)

Drawing Sequence

1. Within Each Trade, Drawings Start With Overview "Big Picture" Information, Then Plan Views, FollowedBy All Other Pertinent Information. Where Effective, Supplemental Information Is Included Directly OnThe Plan View Drawings To Improve The Reader's Understanding.

Miscellaneous

1. The Terms 'Sheet', 'Plan', And 'Drawing' Are Used Interchangeably.

2. For Items That Are Plans, Details, And Other Graphic Items, Titles Are At The Bottom Of The ItemDescribed. For Items That Are Predominately Text Such As Schedules, Titles Are At The Top Of The ItemDescribed.

3. Shading Of An Area Often Is Used To Emphasize An Area To The Reader. Some Of The PossiblePurposes Of This Emphasis Can Be:

B. Defining A Topics Boundary Without Conflicting With Other Linework

C. Help To Emphasize The Existence Of A Part Plan Of The Area

D. Differentiate Line Work In Congested Areas

4. Printing Of The Plans Is Often Reduced, So A Graphic Scale Is Provided On Each Sheet.

How Notes Are Used

1. General Notes Are One Or More Notes In List Form Which Are Not Indicated Specifically On A Plan,Section, Elevation, Or Detail.

2. Key Notes Are Used In Lieu Of Standard Notes Where They Improve Readability, Key Notes AreGathered Together And Listed Collectively On The Drawings On Which They Are Located.

Addenda & Revisions

Some Addenda And Revisions Are Identified On The Drawings Using A . The Number In The TriangleLinks To The Revision Block In The Title Block Section.

Sometimes The Most Recent Change Is Clouded To Provide Increased Clarity.

SCOPE OF WORK

DESIGN CRITERIA

Project Description

The Bliss Hall Building Has Been Experiencing Conditions Of High Relative Humidity During The SummerMonths For Several Years. The High Relative Humidity Has Resulted In Visible Moisture Around WindowsAnd At The Fan Coil Supply Registers. The Moisture Problem Has Been Severe Enough To Warrant TheDeployment Of Numerous Portable Dehumidifier Units To Alleviate These Symptoms. In It's Current State,The Existing HVAC System Cannot Provide Reheat For Proper Dehumidification, Especially During PeriodsOf Low Cooling Loads.

To Correct This Problem, The Fan Coil Outdoor Air Intakes Will Be Blanked Off And The Windows Are To BeMade Inoperable. New Ductwork Will Be Installed To Deliver Ventilation Air To The Occupied Spaces OnThe First And Second Floors From The (2) 100% Outside Air Handling Units In The Basement. In AdditionTo The New Ductwork, New Communicating Thermostats With Dry Bulb Temperature And RelativeHumidity Sensing Capability Will Be Installed In The Affected Spaces. These Sensors Will Modulate The FanCoil Units To Meet The Space Load. The Communicating Thermostats Will Be Tied Together On A BACnetBus And Tied Into The Campus EBI Network.

Scope

The Following Is A Brief Scope Of The Work For This Project (Not Intended To Be All Inclusive):

1. Perform A Detailed Survey Of The Area Of Work To Fully Understand All Existing Conditions.

2. Blank Off The Outdoor Air Intakes On Each Fan Coil Unit.

3. Make All Windows Inoperable. (By TCNJ)

4. Core Holes Through The First And Second Floor Slabs For Installation Of The Ventilation Air DuctShafts.

5. Install Ductwork From Air Handling Units To The Occupiable Spaces On The First And Second Floors.

6. Install Volume Dampers And Supply Grilles For Each Space On The First And Second Floors.

7. Adjust Volume Dampers On All Floors According To Airflow Indicated On The Floor Plan Drawings.

8. Construct Stud Wall Assemblies Around New Duct Shafts, Including Drywall, Taping, Spackling, AndFinish Painting. Rework Ceiling / Lay‐In Ceiling Grid Around New Stud Wall Assembly.

9. Install Communicating Thermostats With Dry Bulb Temperature And Relative Humidity SensingCapabilities. Connect New Thermostats On A BACnet Bus And Tie Into Campus EBI System.

10. Set The Controls On The Fan Coil Units For Targeted Indoor Conditions.

11. Remove And Reinstall Acoustical Ceiling Tiles As Required.

12. Perform Thorough Daily Cleanup In All Areas Of Work.

13. Perform Complete Pre‐Construction Balance Of The Hot Water, Chilled Water, AHU‐1 And AHU‐2Systems To Report Existing Conditions Per Specifications.

14. Perform Complete Post‐Construction Balance Of The Hot Water, Chilled Water, AHU‐1 And AHU‐2Systems Per Specifications.

15. Reinsulate All Existing Chilled Water Supply And Return Piping Throughout Building. (Insulation To BeRemoved By Others)

16. Reinsulate All Existing Cooling Coil Condensate Drain Pipe Throughout Building. (Insulation To BeRemoved By Others)

17. Reinsulate All Heating Hot Water Piping Throughout Building. (Insulation To Be Removed By Others)

18. Revise AHU‐1 And AHU‐2 Control Logic To Suit Updated Sequence Of Operation.

19. Coordinate Controls Integration To The Campus EBI System. Contact Lou Speziale With AdvancedSolutions Sales At 856‐437‐1844.
