2012 Product Overview

Our CookstovesOur cookstoves are beautifully engineered to meet the environmental needs of our planet and the desires of families around the world. Uniting combustion science and cutting edge product design, we create highly efficient, clean burning cookstoves that are as durable as they are beautiful. Envirofit has helped more than 300,000 families breathe healthier air and spend less time and money on fuel. And the world’s forests breathe easier, too.

Our Lighting ProductsWe know how to create products that are at the center of indoor living. Beautiful products that people want to own and care for – engineered to last. That’s why we’ve created Envirofit Lighting. Durable. Affordable. Desirable.

Envirofit Quality Testing Services (EQTS)Through years of hard work, Envirofit has gained a deep understanding of what it takes to make clean and efficient cookstoves and energy products. So we have created our own engineering service business to assist household energy programs and projects around the world. We want to share our knowledge with the world.

The Envirofit WayWe believe the right clean energy products put in the hands of people in emerging markets can change the world. Those products must be affordable, durable and desirable. This can only be done by combining advanced engineering, flexible manufacturing, and modern product design strategies. Creation of local jobs and helping local entrepreneurs develop their businesses. That’s what we do.

Rigorous Engineering & Testing

A clean, efficient cookstove is a simple idea. But designing and producing hundreds of thousands of cookstoves that are both durable and affordable is very complicated. It requires the best science and technology on the planet.

Envirofit and Oak Ridge National Laboratories worked together to create a proprietary alloy which provides the lowest cost, highest performing and most durable combustion chamber ever used in a clean cookstove.

Rigorous Engineering & Testing

We have developed new testing and modeling techniques that allow us to develop products faster – to meet the changing needs of a diverse global market place.

7

Our Stoves Lab at Colorado State UniversityBefore a new cookstove product is ready for high volume production, we subject our prototypes to rigorous stress testing that simulates multiple lifetimes of use. We want to be the ones that find and fix problems, not our customers. To meet this challenge, we partnered with Colorado State University to create the most advanced cookstove emissions testing laboratory in the world.

8

We are opening a factory in Nairobi Africa with more Africa locations coming soon.At Envirofit we are not only producing the best “clean technology cookstoves in the world”, we will be producing them locally within partner country regions. In 2012 Envirofit is launching local manufacturing facilities in India and Africa with our first Africa factory in Nairobi, Kenya opening in early 2012. This will give us the opportunity to produce stoves locally within market regions where we can be closer to our customers and respond quicker to market conditions.

This is a monumental step in bringing jobs and quality products closer to our customers. Our plans are to continue developing manufacturing centers of excellence as our partners’ volumes develop. Our West Africa manufacturing center is planned to be operational in late 2012.

In Country Building OptionsFlexible manufacturing strategies are core to Envirofit’s business model.

For this product, we will rely on local and regional capacity for assembly and installation of stoves, as well as the production of certain components when possible. This approach supports the government objective of creating jobs generation, while also ensuring the highest product quality.

We are working with governmental partners in Honduras to support the scale up and roll out of their National Stove Program. The current goal is to produce and distribute more than half a million stoves over the next few years. We are very proud to say that Envirofit has been selected as the exclusive stove provider for this program. We are replicating this manufacturing model throughout the region.

3GT Turbo Wood Cookstove

The Envirofit G3T forced draft cookstove builds on the performance and efficiency of our G-3300 platform. By introducing a small amount of forced air into the combustion chamber, we can more precisely control the air to fuel ratio in the flame. This creates more complete combustion and lower emissions.

The Envirofit G3T is in preproduction form currently and will be available in mid/late 2012 as consumer demand dictates.

The CH-4400 is the world’s cleanest burning charcoal cookstove. It’s carbon monoxide emissions levels are below the World Health Organization’s 60 minute exposure limits.

The key to unlocking the lowest carbon monoxide emissions in the world is its two part design and its patent pending insulated metal alloy combustion chamber that reflects radiated heat back to the charcoal coal bed, which destroys virtually all of the carbon monoxide normally associated with typical charcoal stoves.

It’s a beautiful design with money saving performance and ultra-low carbon monoxide emissions. Our patent pending insulated metal alloy combustion chamber makes it a durable product that will last for years.

CH-5200 Charcoal Cookstove The CH-5200 incorporates the same combustion efficiency and system as the CH-2200, but is a slightly larger model that is a direct response to the larger family / pot size requirements that are common in much of the world.

Building on the design model of the M-5000 wood cookstove, the CH-5200 is designed for localized production and assembly. This stove will enter production in our Kenya manufacturing plant in mid-2012. This localized production will allow us to create additional local jobs and reduce logistic costs. This allows us to drive down costs to our customers throughout Africa, increasing accessibility to consumers and creating new opportunities for entrepreneurs, distributors, and parts manufacturers throughout the continent.

It’s a beautiful design with money saving, fuel reducing performance. Our patent pending insulated metal alloy combustion chamber makes it a durable product that will last for years.

Stove Accessories

The G-3355 Double pot accessory with chimney is the perfect add-on for customers who want the portability and ease of using the single-pot stove, but need the extra cooking area for large families, festivals, or cooking for visitors.

The attachment is easily moved onto or off of the stove for quick change ability but is steady and sturdy while attached.

The integrated chimney can be used as is – to move any minimal emissions out of the face of the person cooking – or it can be vented out of the home.

Pressure cookers require less energy and use less water, bringing food to cooking temperature faster, and allowing customers to cook much faster.

The Envirofit pressure cooker also makes food safer, since the food is cooked at temperatures above the normal boiling point of water, killing bacteria and viruses.

LPG accessory attachment allows customers the flexibility to use either biomass or LPG fuels in their cookstove. The attachment is easily transferred in/out of the stove for quick change ability.

Using a pot skirt increased the efficiency of the cookstove even more, as it forces the heat from the biomass to very precisely and efficiently transfer to the pot.

The grill attachment is a great accessory for grill-ing meat or vegetables. In early 2012, Envirofit is launching a grill attachment for both the CH-2200, and CH-5200 to ensure an opportunity for a ‘com-plete’ cooking experience.

High Watt Systems

Our High Watt Systems expand our plug-and-play solar lighting technologies for use in larger light and power implementations. Available in multiple wattages – 20W, 50W and 85W, these systems are designed to provide the critical power to illuminate a wide variety of bulbs including fluorescent tubes and high-output LEDs. Like our smaller solar lighting system, our high watt systems include adapters to charge cell phones and power larger appliances like televisions.

35

5 Watt System

Our 5 Watt System is a small, but complete lighting system for a room or two. And it can also charge cellphones and similar electronic devices. It prodives 11 hours of service on an 8-hour charge.

Our plug-and-play connectors make this system easy to wire and easy to use.

36

Torch Flashlight

Our Torch Flashlight is a complete, self-contained personal lighting system. Both a flashlight or a lantern with a push of a button. The Torch’s 17 LEDs are powerful enough to both illuminate a room or provide a concentrated beam. It weighs less than 8.5 ounces (240 g), so it is easy to carry. And the locking hook allows it to be conveniently suspended as a lantern.

The Torch Flashlight’s internal batteries can be recharged by the integrated hand generator, or by plugging into external power source or a battery like with our home lighting systems, so you’ll always have light when you need it.

37

Solar Lantern

Our Solar Lantern is designed to comfortably light a entire room – adjustable up to a very bright 110 lumens. It can also charge cellphones and other small electronic devices.

The lantern’s internal batteries are charged from the detached solar panel. So the panel can be outside in the sun, while the lantern remains inside where it is needed.

The lantern provides 5 hours of light at maximum brightness on an 8 hour charge. And like all Envirofit products, it is designed to be durable, affordable. And it is beautiful.
