Demand-Controlled Exhaust Systems for Dryers, Kitchens & Bathrooms T R U E G R E E N S AV I N G S

Easy and Economical to be Green One of the biggest sources of energy loss in vertical subdivisions (apartments, condominiums, mixed-use buildings) is the exhaust system that ventilates the dryers, kitchens and baths. Regardless of how many appliances are in use, the exhaust system operates ENERVEX offers an alternative to 24/7 exhaust operation that's both economical and "green." Our demand-controlled ven tilation system adjusts the exhaust rate to meet the current demands, reducing operating costs and providing significant energy savings each year. Most ventilation systems run at full...

How Demand-Controlled Ventilation Works In a vertical subdivision (apartment, condominium, mixed-use building), the traditional exhaust system must operate at full speed 24/7, regardless of how many appliances are running at any given time. With demand-controlled ventilation, the system senses when no appliances are running and operates at a very low speed. Once the appliance starts, the Internal appliance fan creates pressure Inside the common duct. The system senses this pressure and begins Increasing ventilation speed. The following Illustration describes the components and operation of...

Think you have to spend a lot of money and retrofit your building just to be "green?" Think ag At ENERVEX, we've been offering sustainable solutions long before it became trendy to do so. Consider the benefits of our demand-controlled ventilation system: Life Cycle Cost, (LCC) ■ EXHAUSTO Demand Controlled Loss from exhaust conditioned air Over a 15 year period a typical demand- controlled ventilation system serving eight dryers costs 55% less to operate a than a fixed speed system. In addition it saves 85% of the cost of exhausting conditioned air. A typical dryer, kitchen or bathroom...

Quiet Performance H Aesthetics A well-balanced demand-controlled system eliminates noise from speed variations or from fans running at full speed 24/7. With ENERVEX's variable speed, direct-drive EFV exhaust fans, broken belts are a thing of the past. Other than periodic duct and fan cleaning, no maintenance is required. Architectural discharge vents, which collect grease, lint and dirt, are located on the wall, which makes them very difficult to clean. Because the demand-controlled system discharges on the roof, it eliminates this Not only is the ENERVEX system fast in response to demand...

MDVS, Mechanical Dryer Venting System Ventilation: Multi-Story Clothes Dryer The Mechanical Dryer Venting System (MDVS) is a demand- controlled ventilation system designed specifically for multi- story buildings that have dryers on each level. This illustration describes the system and its components. differential sensor. MDVS is designed to work with both electric or gas clothes dryers. This is the common main duct that serves all dryers. In applications with multiple dryers, it is possible to use diversity factors, which in statistics are a representation of how many dryers are likely to...

MDVS, Mechanical Dryer Venting System Ventilation: Central Clothes Dryer Facility The Mechanical Dryer Venting System (MDVS) is a demand controlled ventilation system designed specifically for multi story buildings that have a common dryer area, rather than dryers on each level. This illustration describes The exhaust from the dryers is ven- tilated through the termination fan, which is located on the roof. The common main duct fire-rated chase. room close to the dryers. duct connects all dryers smaller than a gravity MDVS is designed to work with both electric and gas fired clothes dryers....

MBESV, Modulating Building Exhaust System Ventilation: Kitchens & Bathrooms The Modulating Building Exhaust System (MBESV) is a demand-controlled ventilation system designed specifically for ventilating kitchen hoods and bathroom fans in multi-story buildings. This illustration describes the system _ ventilator direct-drive opens for easy cleaning. ENERVEX's MDVS and MBESV systems are extremely suitable for retrofitting. This is an example from Potomac, MD where 14 fixed-speed fans were replaced by 14 demand-controlled The system can handle multiple main ducts, which provides substantial...

Performance documented by independent testing In recent years, ENERVEX has participated in a major development project initiated and financed by Enbridge Gas that has tested several dryer issues, including the effects of using the MDVS system vs. fixed speed fans. The project was managed by National Gas Technologies Center (NGTC) in Montreal. Based on more than 35,000 hours of monitoring some of the results were: • Using an MDVS control system has limited impact on drying time but can contribute to a decrease in dryer's energy consumption by 3% while preventing up to 10 times more...

ENERVEX Success Stories Madrigal Lofts, Washington, DC Madrigal Lofts is a breathtaking new construction in Mount Vernon Place, one of the city's hottest neighborhoods. This 12-story, loft-style condominium blends modern design and classic poetic form. It features 38 ENERVEX demand-controlled ventilation systems that exhaust the building's dryers and bathrooms. Demand-control ventilation offers significant energy savings over traditional ventilation system, which has translated into lower operating costs.
