Product Info

The design allows the vent to spin freely under wind load and provide the same exhaust rate as the traditional Hurricane vent. The free area of the throat is NOT impeded, unlike current vent/fan combinations. When required the vent can be powered which provides a huge boost to the flow rate at an extraordinarily high efficiency – far more energy efficient than any conventional powered fan.

The guaranteed exhaust rate regardless of wind speed or ‘stack effect’ can be controlled by digital measurement of a range of physical properties or chemical entities including temperature, humidity, carbon dioxide, etc. With a very low operational noise, the EcoPower is ideal for use in homes, offices or factories.

Key Features

Performance

The ecoPower® concept has demonstrated extraordinary energy efficiency under power load (Below). Exhaust rates per unit of energy are well above that achieved by comparable sized axial fans while noise levels are significantly lower.

Performance Under Wind Power Alone

How does ecoPower® perform under wind power alone compared with the standard Hurricane wind turbine? The results in the table below show the performance of both ecoPower® and standard Hurricane when tested to AS4740:2000 – Australian and New Zealand standard for Natural Ventilators. The results show clearly that ecoPower® provides exhaust rates about 10% greater than standard Hurricane vent due to less throat blockage. Also shown in Table 3 is a comparison of flow rates from AS4740:2000 with the traditional approximation derived from a modified formula for estimating discharge from an open cavity. The latter has been widely used in many product brochures but lacks any scientific basis. It will be noted that the results measured under AS4740:2000 are about 40% of that reported using the traditional approximation.

Real Life Results - Residential Installation

Encenx has performed before & after temperature surveys on recent installations of ecoPower to give you "Real Life" results and demonstrate the dramatic effects of installing ecoPower.

The chart below is actual data collected before and after installing ecoPower on a home in Texas, near Houston. The residence is about 3,900 sqft.

The residence originally had Ridge Vents installed, but the owner complained of high temperatures in the attic, large electricity bills and hot conditions in the upper floor of the home. This is very typical of Texas homes, especially in summer.

The roof decking was being replaced after only 15 years. The ecoPower EP600 was installed to improve temperature and air quality.

Key Results after Installing EcoPower

• 50% drop in attic differential temperature (attic temp minus ambient temp) after ecoPower installed.
• 20% savings in cooling costs with ecoPower.
• Inaudible (nil) noise from ecoPower.
• Comfortable upstairs environment (temperature).
