Bringing proven, long-lasting, energy-conserving, clean technology products and services to New Mexico
The AMAX® EconoMiser™ is ideally suited for retrofit and remodeling applications intended to increase energy efficiency, lower energy consumption, and prolong the life of existing RTUs. We have found in case studies on this technology that ROI on the installation can occur within one to two years of installation. Significant energy savings are of course realized immediately.
How it does this: it deploys a “cooling tower” configuration with an indirect metal coil heat exchanger to achieve adiabatic effectiveness of 115%.
Technical Data
AMAX EconoMiser achieves adiabatic effectiveness of 115%. ASHRAE tables define New Mexico conditions as:
Dry Bulb
96o F
Wet Bulb
61o F
Difference
35o F
If you had a MasterCool system (as an example of an older piece of equipment), comparative temperature profiles with the addition of the AMAX EconoMiser would therefore be:

Core Benefits
of AMAX EconoMiser
Increases efficiency of older units
AMAX EconoMiser works alongside older RTUs to minimize compressor run time by making condenser coils more efficient. Pre-coolers work best in high ambient temperature conditions when condensers become less efficient and maximum AC is required.
Lowers energy consumption of older units
AMAX EconoMiser works alongside older RTUs to reduce shoulder season power consumption by making condenser coils more efficient. Pre-coolers work best in high ambient temperature conditions when condensers become less efficient and maximum AC is required.
Prolongs the life of older units
AMAX EconoMiser works alongside existing RTUs to lower the strain on existing system units by minimizing compressor run time and making condenser coils more efficient. This allows your older units to rest more during peak periods, effectively extending their life. Pre-coolers work best in high ambient temperature conditions when condensers become less efficient and maximum AC is required.
Additional benefits of the system include:
1. Allows existing tonnage to work optimally in peak load periods
2. Lowers strain on older units, extending their life cycle
3. Easily assembled, quick to install
4. System comes in standard sizes, no custom design needed with equipment from all top manufacturers

Technical data
AMAX EconoMiser achieves adiabatic effectiveness of 115%. Since ASHRAE tables define New Mexico conditions as:
Dry bulb 96o F
Wet bulb 61o F
Difference 35o F
If you are planning to replace or add capacity to your system, the AMAX® stand-alone product line can reduce DX tonnage required, so fewer additional units may be required, reducing capital equipment cost and subsequent operating cost. AMAX equipment qualifies for many federal and state tax deductions and utility rebate programs. 1. IDEC maximizes energy-saving potential of evaporative process by means of indirect / direct evaporative cooling in a dual-stage system.
How it Works
AMAX IDEC™, Hybrid™, and Hybrid DX™ deploy pre-cooling technology to increase the effectiveness of evaporative cooling. Supply air is pre-cooled in a “cooling tower,” using evaporatively-chilled sump water. Depending on load requirements, the base unit may have an indirect cooling water coil and compressor cooled coil added.
2. Hybrid uses all the technologies in IDEC and adds an indirect chilled water coil to increase effectiveness.
3. Hybrid DX adds a direct compressor coil to the Hybrid model, for optimal comfort and economy across geographies in all climate conditions.
