Efficiency and Capacity Gains of 20-45%

For large homes or multi-family facilities, Olive Tree Energy provides Geo Max® Systems that deliver from 20% to 45% increases in both capacity and efficiency of existing air conditioning systems.

How it Works

Our GEO Max® Systems accomplish dramatic capacity and efficiency gains by using only a very small quantity of cool water from any available source, such as a geothermal source or a cooling tower.  The proprietary technology uses this water first to lower the high side pressure of the air cooled A/C system to approximately water cooled conditions.  This lowers compressor power consumption and increases refrigerant mass flow. Second, the technology achieves substantial additional sub-cooling of the liquid refrigerant, which also increases mass flow of the refrigerant.

The result is a system that is as efficient as a water cooled system and has greatly increased capacity.


The GEO Max® technology has several outstanding uses for both residential home and commercial building applications, virtually all air-cooled HVACR applications (including air-conditioning systems), pool heater and air-conditioning chiller applications. With this product, any manufacturer's standard heat pump/other AC system, electric heat pump pool heater or chiller equipment can have efficiencies boosted by up to 40%. This can occur with a retrofit application, or when installed along side of other equipment in a new construction setting. GEO Max® has a huge advantage over other geothermal systems because it needs only about 5% of the normal loop length and 10% of the fluid flow rate of a standard geothermal system. Thus, it achieves geothermal efficiencies for a fraction of the cost of a normal geothermal system! 

The GEO Max® can also be retrofitted or installed in new construction on small to very large commercial facilities which have air cooled or DX type HVAC systems. It is a cost effective, flexible system in these applications, and utilizes unique and flexible geothermal technology to provide outstanding efficiency gains, leading to high payback periods (particularly for larger commercial applications). GEO Max® has been successfully implemented in many applications, such as manufacturing plants, a U.S. naval base building, U.S. Post Offices and a Florida school.
