Okapi Fan Control Systems for Solar Collector Air Heaters

About Okapi Fan Control Systems

You need an intelligent fan control system to operate your amazing closed-loop solar air heater. Our patented "Okapi Systems" cleverly drive variable speed fans and blow the heat out of your solar air heater collector where you need it most: at the floor level. Also, they are completely autonomous: they turn on and off all by themselves.

Okapi Systems, with their multiple temperature sensors and sophisticated RISC-chip programming, detect weather trends and delicately control the rate of air-flow through your solar collector. Incredibly sensitive and able to work in partial-sun conditions, Okapi Systems will optimize your solar heat harvest.

Able to operate a broad range of powerful, variable speed fans (if required for very large solar air heater applications) Okapi Systems can be joined with almost any size or design of solar air heater collector to help heat your home, cottage, garage, shed, commercial or public building. 

If you're looking for a solar air heater control system that you can connect to an Android app or PC (for real time data viewing, data logging and much, much more) then take a look at our product line-up, then please review the Okapi Solar Calculator App for Android and the Okapi Viewer app in the "Android and Java apps" section.

Origins of the Okapi Brand:

Greenhill EnviroTechnologies Inc. holds great interest in environmental conservation, preservation of biodiversity and maintaining a healthy planet Earth for future generations. For these reasons, we named our first clean-tech product line after a relatively unknown and endangered species: the okapi.

 By using the name and natural markings of the okapi for our brand, we hope to bring awareness to the innumerable and incredible species that are trying to survive on planet Earth alongside of us.

"Okapis are native to the Ituri Rainforest, located in the northeast of the Democratic Republic of the Congo, in Central Africa. Although the okapi bears striped markings reminiscent of zebras, it is most closely related to the giraffe." (http://en.wikipedia.org/wiki/Okapi)
