UNIT FUNCTION:
Non-fused disconnect switch 'on', service switch 'on', supply air smoke damper closed, fire alarm contacts (by others) 'closed' (jumper if not required), VFD fault contact 'closed'.
EMS Unit on/off=On. Outside air damper opens. Blower will delay on and run continuously. Blowers/Motors VFD speed (see note 1) are controlled (by others). The unit mounted DDC controller with an integral setpoint fixed at 65⁰F will sequence heating (see note 2) and 8 stages of mechanical cooling (see note 3) to maintain the required discharge air temperature.
The discharge air temperature will be reset proportionally from 60⁰F to 80⁰F by EMS to meet required discharge air for space temperature needs.
All door switches 'closed', UV service switch 'on', EngA UV-CENTURION biological growth control lights 'active'.
EMS on/off=Off. Outside air damper closes. Unit is off.
Mechanical cooling is locked out when ambient is below 50⁰F.
VFD for Compressors # 1 & 2 modulate compressors in order to hold discharge air temperature +/- 1 degree Auto bypass low limit will stop unit operation if the discharge air temperature falls below 40⁰F.
Heating and cooling locked out when blower operates below 50% of the supply air flow (30HZ)
Note 1- Multiple VFD's for supply fans; if one fan fails, backdraft damper closes, other three VFD's increase to 100% capacity Note 2- Unit mounted DDC controller provides interface points by MSTP Bacnet control signal to modulate face and bypass damper on the steam heating coil.
Steam valve (by others) Control signal to modulate control valve based on ambient conditions by Engineered Air Note 3- Compressor(s) cycle has minimum run time, minimum off time and interstage timing and stagging on/off by DDC supplied controller to hold required discharge air temperature

VariCel® RF
Extended-Surface Rigid Air Filter with Synthetic Media
Excellent Performance With superior strength and durability, the VariCel® RF is ideal for Variable Air Volume (VAV) systems. It provides a high level of filtration efficiency in those applications where cleaner air is required. With metal cell sides and a layered synthetic media pack, the VariCel RF offers superior dust holding, moisture resistance, and overall performance. Color-coded media designates each efficiency: yellow (90-95%), pink (80-85%), green (60-65%), and white (45-50%). Both single and double-header models are available.
Sturdy Construction and Dependability The VariCel RF, with its galvanized steel cell sides and plastic pleat spacers on the air-entering and air-leaving sides, withstands the most demanding applications. The pleat spacers and expanded metal support grid maintain the shape of the synthetic media pack and ensure that both the efficiency and dust-holding capacity are maximized.
VariCel RF’s rigid construction with supported pleat media pack maintains a compact unitized structure under variable air velocities and repeated fan shutdowns. The interlocked header and cell sides, along the entire length of each side, provide maximum sealing.
Competitive filters are designed with loose fitting headers that allow greater potential for bypass leakage.
Layered Synthetic Media Pack The layered media used in the VariCel RF is a meltblown synthetic protected by a scrim on the air-leaving side. Layering the media provides both a high-efficiency final filter layer that effectively filters fine particulate and an integral lofted prefilter layer that captures larger particulate. Meltblown synthetic media is stronger than fiberglass, non-shedding, and is water-resistant.
Open Header Design AAF’s unique open-header design creates a built-in handle that makes carrying and installing VariCel RF easy. As an added safety measure, we roll the edges of the header to eliminate sharp edges that can make handling competitors’ products hazardous.
Better Air is Our Business ®
• Designed for improved performance and durability
• Layered synthetic media with plastic pleat spacers on both sides

| Twin | City | Fan | now | offers | an | air | measuring | device | as | an | ||
| option | on | centrifugal | fans. | It | is | based | on | the | principle | |||
| of | a | flow | nozzle. | The | inlet | cone | of | the | fan | is | used | as |
| the | flow | nozzle. | By | measuring | the | pressure | drop | through | ||||
| the | inlet | cone, | the | flow | can | be | calculated. | The | system | |||
| consists | of | a | piezometer | ring | mounted | in | the | throat | and | |||
| a | static | pressure | tap | mounted | on | the | face | of | the | inlet | ||
| cone. | A | differential | pressure | transducer | and | a | digital | |||||
| display | can | be | provided. | The | display | must | be | capable | ||||
| of | performing | the | square | root | function | in | order | to | read | |||
| out | in | CFM | directly. | By | testing | fans | in | the | laboratory, |
| Twin | City | Fan | was | able | to | determine | flow | coefficients | for | ||
| various | fan | types. | The | flow | coefficients | were | combined | ||||
| to | give | the | equations | listed | below | by | fan | type. | Based | ||
| on | testing | performed | in | Twin | City | Fan’s | laboratory, | the | |||
| accuracy | of | the | system | was | determined | to | be | +/- | 5%. | ||
| The | pressure | drop | is | measured | from | the | tap | located | |||
| on | the | face | of | the | funnel | to | the | piezometer | ring | in | the |
| throat. | The | inlet | tap | is | connected | to | the | high-pressure | |||
| side | of | the | transducer | and | the | piezometer | ring | is | con- | ||
| nected | to | the | low-pressure | side. |
Measurement of Airflow
| The | equations | below | are | accurate | for | flow | estimation | for | flows | from | 40% | to | 100% | of | wide-open | volume. | According | |
| to | testing | done | previously | at | Twin | City | Fan, | several | factors | affect | the | accuracy | of | this | method | of | determining | flow. |
| The | equations | below | assume | the | following: |
| • | There | are | no | vanes | or | other | obstructions | in | or | near | the | inlet |
| • | Even | flow | entering | the | funnel | (no | pre-swirl) | |||||
| • | Standard | wheel | to | inlet | cone | overlap | ||||||
| • | Accurate | determination | of | air | density | at | the | inlet | ||||
| • | Free | inlet | (consult | Twin | City | Fan | for | ducted | inlet | factors) |

| Selecting | a | pressure | transducer | with | the | appropriate | ||||
| range | is | critical | in | order | to | get | accurate | measurements | ||
| using | the | piezometer | ring. | Since | most | transducers | list | |||
| accuracy | as | a | percent | of | full | scale, | if | the | range | selected |
| is | too | high, | this | can | have | a | significant | impact | on | the |
| accuracy | of | the | flow | measurement. | If | the | range | is | too | |
| low, | there | is | risk | of | damaging | the | instrument | and/or | get- | |
| ting | inaccurate | readings | or | no | reading | at | all. |
| The | following | steps | are | for | sizing | the | pressure | trans- |
| ducer | for | use | with | the | piezometer | ring | flow | measurement |
system:
| 1. | Determine | the | maximum | flow | rate | in | CFM | that | the |
| fan | is | expected | to | produce. | This | maximum | should | be | |
| the | greater | of | normal, | maximum, | and/or | emergency |
conditions.
| 2. | Find | the | formula | for | calculating | the | actual | flow | rate |
| from | page | 1 | of | this | document | for | the | corresponding | |
| size | and | type | of | fan | being | used. |
| 3. | Calculate | the | pressure | drop | corresponding | to | the |
| maximum | flow | rate | determined | in | Step | 1. |
| 4. | Select | the | pressure | transducer | with | the | smallest |
| range | that | includes | the | pressure | drop | calculated | in |
| Step | 3. |
| 5. | Now | take | the | maximum | range | from | the | pressure | |
| transducer | selected | in | Step | 4 | and | use | that | to | calcu- |
| late | the | maximum | flow | rate | that | could | be | measured | |
| with | this | transducer. |
6. Determine an acceptable safety factor for sizing the transducer.
| 7. | Multiply | the | maximum | flow | rate | from | Step | 1 | by | the |
| safety | factor. | If | the | maximum | flow | rate | from | Step | 5 | |
| is | less | than | the | result, | bump | up | the | transducer | to | |
| the | next | largest | size. | Otherwise, | the | transducer | from | |||
| Step | 4 | should | be | used. |
Example:
| Company | XYZ | has | a | size | 270 | BC | SWSI | fan | to | be |
| installed | with | design | conditions | of | 12,000 | CFM | at | 5 | ||
| inches | w.g. | and | standard | density. | What | size | transducer | |||
| should | be | used? |
| 1. | After | speaking | to | the | design | engineer, | it | was | deter- | |
| mined | that | 12,000 | CFM | is | the | actual | maximum | and | ||
| most | of | the | time | the | fan | will | be | running | closer | to |
| 10,000 | CFM. | Therefore, | 12,000 | CFM | will | be | used | for | ||
| the | calculations. |
| 2. | The | calculation | for | this | fan | type | and | size | is: | |
| ACFM | = | 4247.77 | * | (P) | for | standard | density | |||
| Note | that | if | the | density | was | other | than | standard | air, |
| the | formula | would | be | different. | |||||
| 3. | By | rearranging | the | formula | in | Step | 2, | the | following |
| formula | is | obtained: | ||||||
| P | = | (ACFM/4247.77)^2 | ||||||
| so, | P | = | (12000/4247.77)^2 | = | 7.98 | inches | w.g. | |
| 4. | For | the | pressure | transducer | models | being | considered, |
| the | ranges | are | 0-3, | 0-6, | 0-10, | and | 0-20. | Therefore, | |
| for | this | flow | rate | the | transducer | model | is | the | 0-10 |
| inches | w.g. | model. |
| 5. | The | maximum | for | this | transducer | is | 10 | inches, | which |
| corresponds | to | the | following | flow | rate: |
| ACFM | = | 4247.77 | * | (10) | = | 13433 | CFM | ||||
| 6. | Since | 12,000 | CFM | is | the | maximum | and | normal | oper- |
| ating | conditions | are | 10,000 | CFM, | a | 10% | safety | factor |
| should | be | plenty | for | this | application |
| 7. | From | step | 1, | 12000 | CFM | * | 1.1 | = | 13200 | CFM. | This |
| is | less | than | 13433 | CFM, | so | the | 0-10 | inch | pressure | ||
| transducer | is | acceptable. |

PROBLEM:
VFD Induced Shaft Voltages Damage Bearings The use of variable frequency drives (VFD) with AC motors induce electrical voltages on the motor shaft. Once they exceed the resistance of the bearing lubricant, these voltages discharge to ground (typically the motor housing), causing fusion craters in the bearings. Over time, these craters increase in size and number, resulting in frosting, pitting, fluting, and eventually bearing failure. This type of premature bearing failure can cost thousands of dollars in increased maintenance and lost production.
SOLUTION:
AEGIS SGR™ - Electrical Bearing Damage Protection The new AEGIS SGR Conductive MicroFiber™ Bearing Protection Ring™ prevents electrical damage to motor bearings by safely channeling harmful currents to ground. Using proprietary Electron Transport Technology, the conductive microfibers inside the AEGIS SGR provide the path of least resistance for damaging bearing currents, preventing electrical damage to motor bearings and dramatically extending motor life.
Easy to install on motor end bell
Clears any slinger, shaft shoulder or protrusion
Adjustable slots adapt to most end bells
Rigid mounting plate ensures alignment
Slim design, uses less than ½” usable shaft length
Protects motors from catastrophic failure Safely channels harmful VFD induced shaft currents to ground Easy to order and install for any NEMA or IEC frame size www.est-aegis.com
