3

• First stage of filtration
• 30 efficiency
• Large access door
• Pressure differential reading
• Large access door

4

• Coil design with less than 10 fin per inch
• Air flow speed less than 400 FPM
• Stainless steel condensation pan
• Easy to clean

5

• Direct drive fan (no belt to change)
• 8 more efficient
• then belt drive fan
• High efficiency motor
• Low speed motor for longer life
• VFD for room pressure control and longer life
• Large maintenance access

6

• Second stage of
• filtration
• 80-85 efficiency
• Installed on positive positive side of the unit
• Cleaner air

7

• No free wire
• Washable unit

8

• Control section

DEHUMIDIFICATION OF THE AIR
Design temperature

• 93,7F DB
• 74,6F WB
• ASHRAE Reference

Room conditions

• 70F to 85F
• 73F optimal temperature
• 50 Humidity
• Jamesway requirement

Pressure control of the air
Speed controller (VFD)

• Quicker reaction time than damper
• Better precision of control
• Easier trouble shooting
• Easier adjustment

13
AHU Benefit

• Less maintenance
• Filter maintenance alarm
• Better air quality 80 efficiency
• Possibility to heat the fresh air with the
  chiller heat rejection
• Washable
• Lower electrical requirement
• No recirculation, less chance of contamination.
• Possibility of backup
• Only one spare part to keep in inventory (motor)
• Control system specially design for energy saving
  with energy optimization
