When spraying cellulose into an attic, a nuisance cloud builds up preventing clear visibility. To reduce this cloud, it is necessary to add a small amount of water to the material so that it weighs down the dust. The internal wetting system adds a small amount of moisture. After the cellulose has been sprayed, the top layer of cellulose creates a thin crust that stabilizes the material in the attic. This helps minimize the material from falling into the access hole opening.

When adding an internal wetting system, you will need to minimize the build up of damp fibers in the hose. We accomplish this in two ways:

• You will need a double-blower machine. The extra air reduces progressive build-up of fiber and gives you an extended range with damp fibers. You should be able to get at least 80% production rate at 150 ft. of hose with this IWS system and double blower feature.
• Another aspect of reducing the plugging in an internal wetting system (IWS), would be going from a 3" hose up to a 4" IWS tube and hose for several feet then reducing back down to 3" for the remainder of your hose length.

Setup Option 1: Connecting to an on-site water source using a standard garden hose

• A: Water supply from either a hose bib or water tank
• B: Power supply: This plugs into the circuit panel on the machine labeled IWS. The power automatically turns on and off with the blower.
• C: Double jet: Two jets introduce a mist of water to the cellulose in a cast aluminum coupler.
• D: A section of 3” hose from the machine, increasing to a 4” hose, then back down to a 3” hose.

Setup Option 2: Carrying water in a storage tank in a truck

• A: Internal Wetting System
• B: Water Pump
• C: 100 gallon Water tank
• Inset: Double blower (identified by two blower controls), and specially wired outlet for the IWS which is synchronized with the blower to start and stop water spray

Not all insulation machines are created equal. This article is a complementary article to: What Sets Cool Machines Apart from the Competitors. I am NOT about making negative statements regarding other competitors. I believe that highlighting the negatives of other insulation machine manufacturers serves no good purpose. Besides, why should you believe me? Let me highlight the POSITIVE strengths of our machines.

Corrosion and Wear Resistant

Industrial-grade Steel: While the weight of a machine is always a consideration, especially for portable units, we do not sacrifice the quality of build for weight. The Cool Machine brand has struck an excellent balance between strength and weight in its design. Cool Machines uses industrial grade steel, not light gauge steel. The hopper and airlock take constant abuse. The steel we use handles the wear and tear of a variety of insulation products. Unfortunately, the internet does not give you the ability to handle a machine side-by-side. So, the best way to describe our machine is to contrast the lightweight 2012 toolbox to one made in 1940. With decades of industrial machine engineering experience, Cool Machines will provide you with a long-lasting machine. It may be the last machine you ever need.

Powder-coated: The hopper, base, airlock, protective shields, moving parts, and all structural steel is powder coated. Cellulose is corrosive when wet/damp. Powder coating provides a harder more durable surface protection than a sprayed on epoxy. Besides, powder is safe for the environment. Add to that: our machines look very nice for a long time.

Nickel Plated Corrosion Resistant Roller Chain: A reliable chain is key. The scalping auger is chain driven. The environment that these chains work in is rugged. Corrosion is a chain’s worst enemy. The nickel plating protects the chain from the elements.

Rugged, Agricultural Grade Parts

The agitator motors are farm-grade components. They are designed to work in the harshest, extreme environments. Agricultural-grade components double the typical service life of motors in its class. A farm duty motor has better endurance in harsh outside environments and has a higher torque rating for frequent starts and stops under a load.

Redundant Circuitry Protection

Weather and extended use can create a build-up of damaging heat¹. The electrical components of the Cool Machine are protected by redundant circuitry protections.

Circuit Panel: Power trips are inevitable and unintentional. What is intentional is having a machine with easy-to-find circuit breakers. These fuses prevent damaging power surges to the internal circuitry. These breakers are within clear view of the operator so minimal time is wasted on the job-site.

Redundant Overload Circuit: In the event that a power surge pushes past the circuit panel, the agitator motor has an embedded breaker of its own.

Dave Krendl has been on the “cutting edge” of designing and implementing machines for the wall spray cellulose industry. From the inception of stabilized cellulose, engineering has morphed.

The CM300 is our most advanced, turn-key system. In one unit, you have the ability to spray and recycle material with great efficiency. Even as Cool Machines is one of the most competitive manufactures on the market, the CM300 still comes with a $30K plus price-tag.

One of our customers wanted a spray and recycle machine. However, they wanted a vacuum system that could be used separately from the machine to give them flexibility to remove insulation from existing attics. This configuration came in well below $30K! What did we do?

Using the base machine in the CM300 setup, we implemented the following solution:

• CM3500 with a 5 horse power, positive displacement blower
• Modified the CM3500 with a recycling hood
• Insulation Vacuum

Here is how the wall spray and recycling works!

1. Dry cellulose is loaded into the main hopper. NOTE WELL: You cannot use any kind of cellulose. You need to make sure your cellulose is stabilized with starch and includes 100% borate. Cellulose is made with either Ammonium Sulfate or Borate. Ammonium Sulfate, when wet, will off-gas obnoxious fumes. Most cellulose manufacturers have various products.
2. A water pump feeds water to the nozzle. The water is added to the cellulose as it exits the spraying hose.
3. The wet cellulose is sprayed into each cavity. A productive installer will be able to fill a 2×4-8’ stud wall cavity in 30 seconds.
4. Cellulose that falls to the floor during spraying and after shaving off the wall is recycled using a standard insulation vacuum
5. The vacuum recycles the damp material. Since the material is being sent back into the machine, it is critical that floors are free of debris.
6. The recycled material is dropped into the sub-hopper with a hood. The hood is equipped with a window so the recycling operator can have a visual indicator as to how full the sub-hopper is. The sub-hopper is able to be controlled so that damp material is precisely mixed with the dry material to make for a consistent application.

Cool Machines offers multiple blowers in their machines. Multiple blowers are placed into the machines to create higher velocity. Do you really need more than one blower? This article attempts to explain this frequently asked question…

What multiple blowers will NOT do

• More than one blower on a machine does not mean you will have two outputs. Multiple blowers are joined inside the machine.
• Multiple blowers do not increase production. See the article on airlocks for an explanation on how production is increased.

What multiple blowers ARE designed to do

Wall Spray

Wall spray is stabilized by introducing glue or water to the material. When recycled, the material is heavier and requires more velocity to push through the hose.

Internal Wetting System

Cellulose is very dusty. An internal wetting system adds a small amount of water as the material enters the hose. Again, the damp material is heavier and requires greater velocity to push through the hose.

Add Additional Length to Hose

Production rates are based on 100 feet of hose raised to the elevation of 12 feet. 99% of insulation situations require only 150’ of hose, especially with the portable units. There are times, especially in commercial applications where you will want to use longer hose to reach. The longer the hose, the more velocity is required. To maintain the velocity, additional blowers are required. Here are some suggestions:

• If you have a CM1500 and want to use more than 200’ of hose, then a double blower is required. You will need two 20 amp circuits to operate a double blower system.
• The CM2400 is already outfitted with two blowers. You can outfit a CM2400 to have up to four blowers. In that case, where you want that kind of velocity, strongly consider our 5 horse power positive displacement blower. You will need 50 amp service to operate a CM2400 that has more than 2 blowers.

The airlock (D) is probably the most important part of a high production insulation machine. The larger the airlock, the more production. Other factors contribute to production (i.e., force feeding augers, hose size), but the airlock is key and should be one of the key elements in your decision making.

The diagram below illustrates a machine conditioning insulation material in the proprietary Cool Machine brand. Our scalping augers (A) force the material into the shredders (B) where the material is conditioned to provide a bridging-free hopper. The material drops into the airlock for further conditioning. The larger the airlock, the more material. That is how production is increased. When spraying attics, the airlock slide-gate (E) is opened to its largest setting allowing material to freely flow into the airlock.

The slide-gate allows the operator to control the amount of material being delivered. When dense-packing walls, you will close the gate leaving about 4” of access to the airlock. That way, the material will not clog the smaller diameter hose required for dense pack.

The Cool Machine airlock is a perfect cylinder. With high-grade belting material, the airlocks create high pressure minimizing air loss. Every Cool Machine is outfitted with an external gauge so you can view the PSI being delivered to achieve your desired pressure.

The CM1500, CM2400 and CM3000 can be outfitted with multiple blowers (C) or a large positive displacement blower. This DOES NOT increase production as the same amount of material falls into the airlock. However, if you are doing wall spray, need an internal wetting system or want to go further length on your hose, the multiple blowers are important to increase the velocity of air pushing the material.

In summary, the Cool Machine brand offers a proprietary system that increases production:

• Scalping augers which force-feed the airlock.
• Larger airlocks
• Perfectly sealed airlocks to sustain greater PSI

So, what are the basic elements that make a Cool Machine Insulation Blower an excellent choice?

	Airlock. High precision extruded cylinder. Not a rolled piece of flat metal. We get a higher airlock pressure and get longer seal-life. Augers. With our specially designed scalping augers, the material is conditioned so well that it flows easily and does not require sticking your arm into the machine to remove voids.
	Bearings and Blowers. Cast Iron, Heavy Duty, triple sealed, easy to grease bearings on all of our machines. We now offer the “Magnum Super Blower” which provides greater air volume and longer wear life of the blower. In fact, this now doubles the life of the blower.
	Coatings: We use a high grade durable powder coating on all machines to last a life-time. This reduces rusts, scratching and provides a nice appearance. This eye catching appearance projects quality and professionalism to your customers.
	Drive system: The CM1500 and larger machines use a separate gear-box and motor combination. Separating the units for replacement can save hundreds of dollars. The dedicated gear-box provides a greater endurance component.
	Ergonomic design: The low-profile, slim-line design allows placement along the wall of your truck or trailer with the hose pointing outward. This eliminates trip hazards when loading machine while increasing operator mobility and payload capacity. You can load a 8’ wide trailer with a skid of material with plenty of room to spare!

Are you frustrated waiting for and traveling to rent a machine from a local building supplies store? Let us help you!

If you currently use machines provided from a local building supply store, here are some problems you will face…

Undersized hose: To satisfy the rental market, local stores rent units with hoses designed to blow material into attics as well as walls. The small diameter hoses are prone to clogging and stopping production. Finding and expelling a clog from insulation hose is time-consuming and can be quite frustrating.

Slow production: Rental units are not designed to push material. They typically max out at 500 pounds per hour. A homeowner will not realize the time they are spending, however, a contractor’s patience will wear thin!

Maintenance: Rental units are not designed for day-in-day-out working conditions. Since they are used daily by homeowners and people who do not care for the machine, the contractor often spends more time repairing these units.

Undesirable results: Since the machines have lower production, PSI and smaller hoses, it is very difficult to make your job look nice. The material is not conditioned well and more settling occurs.

Scheduling problems: These machines are dolled out on a first-come, first-served basis. It is one thing for you to be frustrated, it is quite another for your clients.

As an insulator, one of the difficulties faced with various machines is the consistent flow of material. How many times, sitting in an attic, will some insulation machines produce air with no material, then to have a large wad of material shoot out the end like a canon. It is frustrating. Cool Machines provide an answer that other manufactures have not. It is called “scalping augers.” These are based on decades of engineering knowledge, experience in the field, and a deep family heritage of insulation manufacturing.
