"the net result can be a 20% increase in the heat transfer efficiency that is, a 20% increase in the amount heat
rejected per unit of fan power input. The deep coil concept looks most promising in low static applications where propeller fans are used (and ductwork is not required), such as air-cooled condenser coils and dry coolers." ...CDH Energy,

How Does The DEEP Coil Work

DEEP Coil Attributes 

Proven & Guaranteed Attributes


Potential Attributes (all entirely possible by extension of engineering logic within limits of reason and prudent expectation) -

Climate Change and DEEP Coil - Climate changer requires grass-roots response.  DEEP coil stands to make a significant contribution.

Independent Laboratory Tests

DEEP Coil has evolved over several years and after going through exhaustive testing on successive prototype samples.  These tests have revealed an undisputable performance pattern.  Many empirical comparison tests have been conducted between true DEEP coil sample and equivalent thin coil sample.  These tests were conducted at independent Nationally Recognized Testing Laboratory (NRTL) Intertek Testing Laboratories in Cortland, NY.  See sample coil D1 data.

According to this pattern, the DEEP coil provides at least 20% fan power saving for the same amount of heat transfer over the equivalent current-design thin coil and 10% compressor/pump power reduction.  See basic DEEP coil design-related formulae.

DEEP Coil Application 

Basically, DEEP coil is a better alternative to any fin-tube coil:  a fin-tube coil used in refrigeration application as in indoor evaporator or outdoor condenser coil, or fin-tube coil used to cool down hot fluids in industrial/process heat application like dry-coolers.

Conversion of slab coil to DEEP coil - The immediate and most appropriate application at this time is to replace any slab type condenser coil with equivalent DEEP coil.  Under such an upgrade, minimal changes to the product design are needed. 

Conversion of U shaped condenser coil to DEEP coil The "C" or "U" shaped coils can be converted to DEEP coil pattern to realize both energy reduction as well as OEM cost reduction.

Comparison to Other Energy-Related HVAC/R Innovations

DEEP Coil technology is one of those rare opportunities where it provides substantial cost savings to the OEM, and, concurrently proportionate savings to the consumer.  For example, the micro-channel heat exchangers claim to provide energy savings to the consumer, they also increase the OEM cost, putting the payback period several years down after commissioning of the equipment.  Or, consider the scroll compressor.  It only provides about 15% improvement in the compressor power consumption, but cost more, making the payback period longer.  Unlike the DEEP coil, the scroll and the micro-channels, do not provide fan power savings.  For this reason alone the DEEP coil technology stands out in the list of recent HVAC/R innovations.

Coil Selection Software

A limited coil selection software has been prepared based on the test results and formulae developed to this date.  It is currently being tested and refined.  Please check back.

OEM Cost Savings

The DEEP coil allows the design engineer to reduce the compressor h.p., outdoor fan h.p. and indoor fan h.p. while retaining the same performance.  In the optimum stage, whereas if a 1 h.p. compressor was needed, the DEEP coil allows it to be downsized up to 1/2 h.p.  Same goes with fan motor and blower motor.  Alongside comes reduction/elimination in ancillary components/controls/materials like motor protection, contactors, wiring, mounting hardware, packaging, shipping and the like. This results in a smaller and lighter overall machine/appliance.  All these steps reduce the product cost. Check here for residential and here for commercial savings.




According to the United States Department of Energy, today's buildings consume more energy than any other sector of the US economy, including transportation and industry.

Pay for results, not for experimentation, development or computer gobbly gook charts!!

This is a very young proven technology.  It has a long way to evolve and mature.  This is an exact time to get involved, develop it to maturity and reap benefits along the way and thereafter for decades to come.   

Acute Problem = Major Opportunity - Every acute problem (according to wise people) provides an enormous opportunity to advance human knowledge and skills and to achieve your aspirations - be it service to humanity, wealth, accomplishment, acknowledgment,  or other.  DEEP coil is one such opportunity where you can make a difference, rather than be a mediocre 'me too'.

A ground floor opportunity.  Embark on the new generation! Dare to be different!  Contact today: 

DEEP Coil enmerged more than 10 years ago.  Yet, the worldwide HVAC/R industry, despite the clamor over climate change, continues to  manufacture products that cost nearly twice as much and will require nearly twice as much energy to operate over some 30 year life span of the product. Don't understand!

                Green Technology Proponents: where did you all go!  

Outside the Box - DEEP Coil is a result of audacious "outside the box" thought and logic. It is something not possible to do as a corporation employee.  It is mind-torture for conventional engineers, who just can't get it.
