Small Dtm – “High Velocity” • HIGH VELOCITY • Sales term used by SpacePak and others. • HiV trade name for ESP. • More accurate terms: Higher Pressure or Small Diameter duct system. • Ecologix trade name is Small-Dtm for small diameter duct • APPLICATIONS • Vertical town homes. • Custom homes w/in-floor • Multiple suites or fire breaks.
Small Dtm:Multi-Level Town Homes • Q:Why use Silent Duct in tall buildings? • A:Stack effect- hot air rises to top floors. • In Winter, less heating air is needed on top floors and more heating air needed on lower floors • In Summer, more cooling air needed on top floors and less on lower floors
Small Dtm systems • Higher pressure – drives air to far branches. No problem getting air four floors away • Multiple small mains – easy to rebalance from summer to winter. Dramatically reduces homeowner complaints and call backs for builder
Small Dtm Q & A • Is Small Dtm High Velocity? • NO technical definition exists for High Velocity. ASHRAE mentions medium and high pressure, but no standard provides a definition to work from. • Does Small Dtm meet the building code? • YES… BUT…SD operates at a pressure above the range recognized by residential HRAI sizing practices. Just like SpacePak, ESP(Tempmiser) and Unico, the system needs to be an Engineered design. Follow installation instructions!
Small Dtm Q & A • Isn’t high pressure/ High Velocity duct work wasteful of energy? • YES! Pumping air up to 2” of static pressure just to distribute air IS wasteful. That is why: • SD operates at 1” maximum pressure • Eco-duct modulates to lower fan speeds for most of the year. The duct only sees high pressure on the coldest days of the year, when the full capacity of the system is needed. (NO other high pressure duct system does this.)
Small Dtm Q & A • Can an Ecologix air handler be connected to existing 2” branches? • YES! However, the factory engineers must verify the duct design • Usually requires eco-duct with EC motor • May require motor up-size • May require supply mains up-size in basement
