Solar ventilation air heating -
Conserval SOLARWALL® cladding that heats fresh air
Years of research and testing has resulted in a totally new
concept in solar heating, the highest solar efficiencies ever
obtained in air heating with no glazing!
The all metal SOLARWALL® is engineered to heat outside air and
can be coupled to most ventilation fans. When used with
Conserval's air distribution system, additional energy is saved
by destratifying the ceiling air.
The SOLARWALL® panel looks like a conventional metal wall and is
available in a choice of dark colors. The porous surface has
tiny openings to allow air to pass through picking up virtually
all the solar heat reaching the metal.
The metal cladding on the wall becomes the heater for outside air
entering the building. Dark metal heats up when exposed to the
The SOLARWALL® cladding allows this heat to be collected and put
to use. It even collects heat on cloudy days and at night.
Millions of dollars each year are being saved by corporations and
governments around the world with the SOLARWALL® system.

Solar Panels for agricultural crop drying
Solar energy can be used to dry most crops and in processes requiring warm air. In fact, solar heat is often preferred since it will not burn or harm many delicate foods which often happens with steam or burning fuels. Solar heat is non polluting and best of all, it is free. Existing commercial drying operations can be converted to solar heat by installing SOLARWALL® panels on a nearby roof or wall and connecting them to the intake of the drier fans. All of the air would pass through the solar panels where it is heated and then on its way to the drying chamber. The existing burners can either be turned off or used to top up the heat at night.
In new facilities, the drying chambers can be designed for solar heating with the entire roof and walls of the chambers and storage and production buildings covered with SOLARWALL® panels. Each square meter of SOLARWALL® panel is roughly equivalent to a 500 watt heater.
Operation: The SOLARWALL® system has been tested by numerous governments and independent testing agencies and the results show average solar efficiencies of over 70%.
The USA and Canadian energy agencies both said that the SOLARWALL® design is the most efficient solar heater available. The solar cladding has numerous openings across its surface to draw in outside air and at the same time, allowing the air to be heated by the sun as it passes over the metal absorber.The special coating is designed to absorb as much solar radiation as possible and functions for years in direct sunlight without maintenance.
SolarDuct (tm) Rooftop Solar Air Heating Module
A rooftop application of the SolarWall(r) ventilation air heating system. Used as a "front end" to existing air handling or HVAC unit can raise incoming fresh air temperature by 20 celcius saving as much as 25% on ventilation heating expense.
SOLARWALL® solar ventilation air pre-heating system.
The SOLARWALL® is very cost effective and captures over 70% of the sun's energy. This simple panel may be considered for any building needing ventilation air, air make-up or heating. The SOLARWALL® system for a high-rise heats the ventilation air which is used to pressurize and ventilate the corridors on each floor. The SOLARWALL® is ideal to heat air for air tight residential buildings, and can feed into a heat recovery ventilator or a continuously operating furnace fan.
The SOLARWALL® system for a typical industrial building or warehouse saves energy four ways: pre-heats make-up air with solar gain; recovers heat radiating from the wall, creating R-50 equivalent insulation; reduces conduction heat loss through the roof and reduces heat loss in exhaust.
Monitoring on both apartments and industrial buildings has shown typical SOLARWALL® temperature increases of 20-25°C over ambient. Due to these SOLARWALL® energy savings, the pay-back for industrial buildings has averaged 2.5 years, and apartments about 4 years.
The SOLARWALL® is metal siding covered with thousands of tiny holes and mounted on the south wall of a building. Unlike glass covered solar panels, the SOLARWALL® looks like regular siding and comes in any dark colour. As the sun shines on the dark colored SOLARWALL®, air at the surface is heated and starts to rise up the surface of the panel. This pre-heated air is drawn through the pin point holes that are closely spaced on the panel. The air is drawn from the back of the panel and is distributed throughout the building by either the existing ventilation system or supplementary fans. A perforated flexible ducting system is used to distribute the air for industrial buildings.
