QADUCT

High Level Explanation of What we Do…

Raw Polyethylene

UL181

Add UV Inhibitors

Notes:

We developed and trademarked two types of ductwork systems marketed under the names AKDUCT (transite) and QADUCT (above ground). These proprietary technologies were founded by CDC Enterprises, Inc. in August, 2001. We started to manufacture and market plastic (HDPE) insulated heating and cooling ductwork in August, 2003. From that point on, CDC Enterprises, Inc.'s goal is to engineer and manufacture all the related fittings necessary for a complete heating and cooling supply system designed for residential, commercial, and industrial sites. Today we are in full force production of underground and above-ground polyethylene insulated ductwork.

AKDUCT® & QADUCT™ provides the benefit of an air-tight and water-tight HVAC ductwork installation, which can be pressurized more than a common duct working pressure. As a result of the ability to create a slightly pressurized duct system, builders can now use smaller heating and cooling systems, smaller duct sizes, and can be assured of substantially more efficient operating systems after construction is complete.

QADUCT is an energy efficient, pre-insulated duct system that is completely pre-engineered and easy to install. It conserves energy by being air-tight and thermally efficient. It delivers improved indoor air quality. QADUCT is manufactured using a HDPE (high density polyethylene) composite material for durability and light-weight construction, but with a natural FR (fire and smoke retardant) filler added to enable it to pass the UL 181 regulations for above-ground ductwork applications. QADUCT is mold and mildew resistant, will not rust, will not crack under pressure and is extremely durable.



7


What is AKDUCT? � Created for underground air duct applications � Air tight above 10” water column pressure � Water tight, applications for Below Flood Elevation� Mold and mildew resistant, Close Cell Polyethylene � Environmentally Friendly; Recyclable, non-toxic� Light weight � Self Insulted tested to perform like PVC wrapped w/R10� Easy to assemble � Easy to cut � Affordable � Modular � Durable � Available in standard sizes 3” - 24”

Our ductwork products are classified as High Density Polyethylene (HDPE), which is a closed cell plastic material with an additional high thermal property. It is unique to other materials because it is manufactured with food grade plastic that is safe for humans and the environment. The material is mixed with a foaming additive during manufacturing to achieve the density and performance parameter desired. The preformed ductwork has the characteristic of a smooth low friction surface that is resistant to mildew, mold, and Radon; under pressure it will not crack and is non-toxic and recyclable.

In addition, the ductwork is self-insulating, adjustable and easy to install. A thermal efficiency performance that has been test proven equivalency to deliver effectiveness comparable to underground PVC coated spiral and PVC ductwork wrapped in R10.

How we do it…

Re-cycle

ROTOMOLDINGRotomolding is useful in QADUCT and AKDUCT product lines. This process to create one piece seamless and stress free with superior surface finish is here. AKDUCT products can be up to 60 inches or as small as 3 inches to create a complete air distribution line.Rotomolding is a method that involves the slow tumbling, heating, and melting of a thermoplastic type powder in a bi-axial rotating mold to produce seamless, hollow plastic parts. This process is typically used to mold hollow parts, especially those with complex and varied shapes not easily obtainable by other hollow-art processes. It is a virtually a shear-free and pressure-free process. The wall thickness uniformity and part weight can be easily maintained. There is very little waste of material due to scrap. Process StepsThe Rotomolding process begins by placing a pre-measured amount of plastic material (in either liquid or powder form) in a cavity. The mold is then closed and indexed into an oven where it and its contents are brought up to the molding temperature. CDC Enterprises production capabilities uses multiple state-of-the-art rotational molding machines, including a process-controlled system. As the mold is heated it is rotated continuously about its vertical and horizontal axes. This biaxial rotation brings all surfaces of the mold in contact with the plastic material.

The mold is rotated within the oven until all the plastic material has been picked up by the hot inside surfaces of the cavity and dandifies into a uniform layer. Rotating arms move the mold out of the oven and into the cooling chamber. Air, or a mixture of air and water, cools the mold and the layers of molten plastic material. This cooling process continues until the part has cooled sufficiently to retain its shape. The machine then indexes the mold to the loading and unloading station. The mold is opened and the part removed. A new batch of material is then placed in the cavity, the mold is closed and the process is repeated.

Injection moldingOur clamps use injection molding. This is accomplished by large machines called injection molding machines. The resin is injected into the mold by a reciprocating screw or a ram injector. The reciprocating screw offers the advantage of being able to inject a smaller percentage of the total shot (amount of melted resin in the barrel). The ram injector must typically inject at least 20% of the total shot while a screw injector can inject as little as 5% of the total shot.

Extrusion molding

Our three 3" High Velocity pipes are manufactured using extrusion molding, which is a process, forcing a solid metal through a suitably shaped orifice under compressive forces.

CDC ENTERPRISES, INC uses the hot extrusion process. In this process, a heated billet of metal is placed in a cylindrical chamber and then compressed by a hydraulically operated ram (see illustration). The opposite end of the cylinder contains a die having an orifice of the desired shape; as this die opening is the path of least resistance for the billet under pressure, the metal, in effect, squirts out of the opening as a continuous bar having the same cross-sectional shape as the die opening. By using two sets of dies, stepped extrusions can be made. The extrusion is then cooled and forms a solid shape. The tube may be printed upon, and cut at equal intervals.



11


Once this is done the mold is removed from the oven and allowed to cool for a period of time

The finished product is then removed from the mold, clean, labeled and boxed

Installing Plenum Adapter1. Once the plenum hole is dug along with the

trench for the system set your plenum in the hole butting directly up to your initial run trench

2. Place a foam block in trench about an inch away from the plenum

3. Place your plenum adaptor flange pushed snuggly against the plenum and the throat resting on the foam block

4. Set plenum w/ attached adaptor back in trench, level, and you’re ready for your first 8’ piece of pipe

AKDUCT has several properties that make it very uni que from “traditional” air duct materials:

•Proper restraint must be used when coupling pipe ends to prevent pullout from hydraulic forces or temperature changes.

•AKDUCT HDPE length shrinks 1 inch per 100 feet of pipe length with a 10°F temperature drop, but remem ber ground temperature changes very little so it is unlikely to pull out of restrained clamp and gasket, But still pay careful attention to installing clamp and gasket. One great advantage of underground air ducting is the constant temperature found in earth as nature plays a role in the Thermal Mass. This is why AKDUCT out performs conventional above ground air duct systems.

•Preinstall without clamp and gasket is necessary to make sure you have the lengths and elbows correct to trench. Once gasket has been firmly applied and had time to cure it be very difficult to remove in order to make further adjustments.

•Creep is continuous yield of material under stress. HDPE will creep if the stress placed on it gets above a certain level (refer to ICC-PMG-1023). Follow installation instructions of 2" of pea-gravel above trench and pipe. If great care is not taken when installing pipe in trench for use on long trunk systems, stress level can be exceeded and fittings that work great today may fail later as the HDPE creeps. Some contractors will use a cement slurry as a reinforcement to create a uniform cross section in areas they suspect issues.

•Low coefficient of friction means HDPE is very “slick", that means air flow internally is higher but for the outer perimeter this makes clamp and gasket to rotate on the pipe or migrate along if care is not taken to press gasket firmly around perimeter.

Step 5 Attaching Air Test� Put end cap on end of

pipe that was cut #1� Attach steel plate to

opposite end with AAS� Attach valve� Apply pressure to system

via hand pump or compressor

� Attach manometer and open valve

� Observe

A manometer is a pressure measuring instrument, usually limited to measuring pressures near to atmospheric. The term manometer is often used to refer specifically to liquid column hydrostatic instruments.

-----------------------------------------------------

OPTIONAL AIR TEST ASSEMBLY:

Place a bead of caulk under the air test plate.

Position air test kit over existing hole in top of plenum.

Screw down using screws provided. Caulk around outside. If not using plenum attach air test plate to end cap and do the same pressure test. Allow caulking to dry 24 hours prior to testing.

Fill pressure gauge to 1.5” W.C. on the manometer. (Note: - .75” and +.75 is 1.5” of W.C. pressure). Systemwill hold 1.5” of W.C. for 5

The customer reported that in the period of time since the system modification the building comfort has greatly improved.

This report supplies before and after data regarding system air flow comparing a conventional flex duct system to an AKDUCT system. The unit tested is an ICP straight cool mobile home package system with a 9.8kw electric heater. In both cases, the return is a single duct from a floor mounted return to the cooling unit.

The supply duct splits into two supply trunks that feed chase mounted pipe supplies to the ceiling supply trunks and registers.

The customer reports that in period of time since the system modification, the building comfort has greatly improved. The system is reported to cycle normally as opposed to continuous operations. The customer also reports a reduction in the power by $40 dollars per month.

AKDUCT PLASTIC vs. PVC DUCTING BY COHEAT TEST METHODOLOGY

This test was conducted by using R10 insulation on the bottom, both sides and the top, which exceeds the

requirements for insulation for both the Wisconsin UDC & CBC codes. The test is a demonstration of heat

transfer through a pressurized air duct system and shows the other factors that may contribute to the

complexity of heat conduction measurements, such as: thermal transmittance that includes convection plus

radiation; pressurized air movement; radiation through a cylindrical surface, emissivity of the duct surface,

thermal diffusivity of underground air ducts; and all could contribute directly or indirectly to the total fuel

utilization efficiency of the duct system.

COMMERCIAL AIR TEST

The flange joint sustained 2-1/2” times the rate pressure or 25 inches WC pressure for 1 hour along 40

inches / WC and 50 inches W. pressure for 1 hour, with no bubble leakage indicated or separation of the

joints. http://www.akduct.com/doc/PRESSURE_TESTING_OF_ 20inch_flange_Duct_report_09078

INSTALLATION INSTRUCTIONS

http://www.akduct.com/doc/AKDUCT_INSTALLATION_INSTRUCTIONS.pdf

PRESSURE TEST OF 10” DUCT PIPE / SUMMARY OF RESULTS: The AKDUCT 10” plastic duct pipe joint connection/clamping system in an unrestrained state, sustained an

internal pressure of 1.5 psi (41.5” WC) for 5 minutes with no leakage or separation.

The system momentarily reached the pressure of 1.75 psi (48.4” WC) at which point the end-cap was noted

pushing out of the clamp until it separated enough that leakage occurred.

The tensile force (pull apart pressure) on the system joints was calculated to be 170 lb at 1.5 psi and 198 lb

at 1.75 psi.

KFI ENERGY ANALYSIS COMPARISON REPORT / EXECUTIVE SUMMARY:

Karges-Faulconbridge Inc. completed an independent analysis of the data of the June 28, 2007 report titled

“Temperature Performance Test of AKDUCT vs. PVC” conducted by a certified laboratory. The Thermal

Distribution Efficiency (TDE) for AKDUCT was determined to be 95% and the TDE for the PVC was

determined to be 93% from the data collected for temperature (in BTUH) for input and output. The

Thermal Distribution Efficiency of the AKDUCT is essentially the same as the PVC Duct System which

was insulated with R-10 per the standard referenced design by typical state building codes for energy

efficiency.
