The Innovation

How it WorksCommercial or residential, the basic concept is the same. Micro mist is injected into the air, evaporates almost instantly and coolsalmost instantly and cools the air around thearound the AC unit.

The Innovation

How it WorksCool-n-Save® forces air temperature down by about 30 degrees. If outside air is 98ºF, inside the shield it30 degrees. If outside air is 98 F, inside the shield it is only 68ºF. That means the AC unit gets a head start as it cools your building.

RESULT: Fewer and shorter cycle times, decreased head pressure, and significantly improved energy efficiency for the same cooling power.

Tulane University Studyy y

“By using the Cool-n-Save® system, even in a climate that endures higheven in a climate that endures high humidity, the heat transfer from the refrigerant to the air is substantially i d Thi ff t i li th tincreased. This effect implies that cooler air will be able to circulate and decrease the time the condenser unit runs, thus reducing electricity cost to the user."

A large warehouse/retail location in a metropolitan areaA large warehouse/retail location in a metropolitan area. Prior to installation, one HVAC unit consumed 8,802 kWh. After Cool-n-Save was activated, consumption dropped

6 523 kWh h 25% i B d hto 6,523 kWh – a more than 25% savings. Based on the local rate of $0.15 per kWh, the client may realize a NET savings of $1,435 per month for one unit. There are more than 30 condensers at this location – the estimated annual savings is more than $500,000.

System Components

Non-Invasive InstallationInstallation does not require tear-downs or disassembly of the rooftop units. Installation has almost no impact on building operations (system shut down isoperations (system shut down is not required). Depending upon local building codes, permits are usually not requiredusually not required.

System Components

Cool Pump™pCommercial systems are equipped with our proprietary control pump. Cool Pump ensures a steady flow of treated water from the building water supply to the mistingwater supply to the misting nozzles. It senses condenser activation through a low voltage relay switch connected to therelay switch connected to the HVAC thermostat.

System Components

Cool Release™A patented and environmentally friendly water treatment system h i hibi i l ( l i )that inhibits mineral (calcium).

Refilling the water treatment canisters for our commercial system is a simple process.

Residential customers use self-Residential customers use selfcontained 3-month and our exclusive 6-month cartridges.

System Components

Cool Array™yThe pre-cool shield is deployed by an array of micro-nozzles designed to your specific HVAC requirements. The layout and pattern of nozzles is determinedpattern of nozzles is determined by the type of coil system and the area to be covered.

System Components

Microguard™gAdded for greater efficiency and protection; Microguard is a siloxane based maintenancesiloxane-based maintenance treatment that inhibits mold growth and stops all corrosion on coils, fins, copper tubes, fans and cabinets. Microguard also increases laminar flow of air over the fins. Microguard has an 11-year performance record.
