Solutions

2. The AMAX System
AMAX uses multiple heat exchange stages to
maximize the energy savings potential of
evaporative cooling while maintaining comfort
across a broad range of ambient conditions.
AMAX offers Indirect Only Evaporative Cooling
(IEC), Indirect/Direct (IDEC) and Hybrid DX
configurations to meet all cooling requirements
while saving up to 80% of the electric cost of
comparable compressor based systems.

3. AMAX Applications
• AMAX offers the greatest energy saving benefits in
extreme climate conditions- the hotter the ambient
conditions the better the performance compared to DX.
• AMAX can provide 100% outdoor air and is ideal for
casinos, hospitals, schools, restaurants or other
installations that require large amounts of fresh
conditioned air.
• AMAX Return on Investment is greatest when large
amount of process cooling are required for extended
periods – for example, in data centers, manufacturing
facilities etc. Outdoor air is not required for these
applications.

4. AMAX Indirect/Direct Evaporative Coolers
Commercial and Industrial Cooling Solutions
• Custom Engineering Solutions with
variable sizing and configuration to meet
all requirements.
• Powered Economizers and Powered Pre-
Coolers sized for quick retrofit to existing
RTUs
• Integrated chilled or hot water coils for
cost effective full HVAC solution.

5. AMAX Features and Benefits
• Up to 125% adiabatic effectiveness
• EER 40+
• Competitive pricing and low installed cost
for quick payback
• Rugged, proven and designed for harsh
environmental conditions
• Easy assembly and maintenance
• Full engineering support

6. AMAX Retrofit Options
• Powered Economizers™ in IDEC or Indirect
Only configuration significantly reduce DX
cooling hours while providing cold conditioned
fresh air.
• Powered Economizers can also be used to pre-
cool condensing units for significant energy
savings.
• Adding low cost Powered Economizers to RTUs
results in Energy Savings, Rebates and
Extended Life of the RTU.

EasyStreet Sustainablility Data Sheet
• “Energy-saving technologies such as Indirect Evaporative Cooling…
reduce costs as well as carbon emissions while directing more
power to customer cabinets.”
• “With this state-of-the-art design we have achieved an estimated 1.3
PUE (Power Use Effectiveness) where a traditional data is typically
above a 2.0.”
• PUE is calculated by dividing total facility power consumption by
server power use.
• PUE with standard CRAC was estimated at 1.6. PUE with AMAX is
estimated at 1.3. Total AMAX cooling power use is .07.
• AMAX power consumption is estimated to cost $7,000 per month
and save $30,000 per month compared with traditional CRAC units
according to Rich Bader, President and CEO of EasyStreet.
