RenewAire Introduces the DN Series of Non-Compressorized
DOAS with ERV.
DN Series is a flexible, modular, configurable DOAS with
mix-and-match components featuring RenewAire’s proprietary
static plate core ERV.
a leading manufacturer of HVAC and IAQ products, has
introduced the DN Series, a non-compressorized,
fully-integrated dedicated outdoor air system (DOAS) using
state-of-the-art energy recovery ventilation (ERV) with
static plate enthalpy core technology. The DN Series is
designed for sensible and latent load management that can
reduce air conditioning equipment tonnage by up to
25-percent in healthcare, educational, multi-family and
other commercial building applications.
The DN Series offers
engineers and contractors a flexible, modular and
configurable DOAS. Configurations can mix-and-match any
combinations of a variety of cooling coil methods, hot gas
reheat module, gas or electric heating sections and fan
strategies. Besides a traditional draw-through airflow
configuration, engineers also have the option of a plenum
fan blow-through that provides a better cross-sectional air
delivery and up to 95-percent coil coverage.
The DN Series is available in
a DN-2 (375 to 1,650-CFM), DN-3 (750 to 3,300-CFM) and DN-5
(1,125 to 4,950-CFM) enthalpy core array models for both
indoor mechanical room or rooftop locations. Cabinets are
available in one-inch-thick R-6 or two-inch-thick, thermal
break R-14 foam insulated double walls constructed of sturdy
20-ga. galvanized steel rated for 1,000-hour salt spray
protection or with a 2,500-hour option.
static plate core is its competitive edge. It boasts a
near-zero exhaust air transfer ratio (EATR), the lowest in
the HVAC industry, without requiring energy-intensive purge
cycles. With no moving parts, the failsafe static plate
dehumidifies more efficiently versus an enthalpy wheel,
which requires parasitic power for motorized rotation. While
wheel technology inherently suffers maintenance and
reliability costs, RenewAire’s static plate boasts the HVAC
industry’s best uptime performance that’s backed by a
10-year product warranty. Additionally the DN Series also
carries a performance warranty that guarantees the original
operating specifications for 10 years without any
The DN Series’ integrated,
programmable controller is preset and programmed by factory
engineers to the consulting engineer’s operational
specifications. The “plug-and-play” unit requires only
connection to facility power and the building automation
system (BAS), which significantly reduces contractor
installation time and eliminates jobsite programming errors.
Its BACnet or Modbus platform allows great flexibility in
controlling operational effectiveness and user activity
indoors through any combination of RenewAire’s temperature,
humidity, occupancy, static pressure, fire/safety, CO2 and
IAQ sensor accessory options.
The DN-Series’ is certified
under AHRI-1060 and fulfills requirements of ASHRAE Standard
90.1 and the International Energy Conservation Code (IECC).
It can also add to a project’s LEED® credits as well as
qualify for WELL Certified® and WELL Compliant® standards.
The DN Series uses
cutting-edge components, such as electronically commutated
(EC) motors, direct drive fans and optional variable
frequency drives (VFD).
Other DN Series features
self-contained, modulating hot gas reheat option that is DDC-controlled;
• Compatible with almost any imaginable primary HVAC
application, such as direct expansion (DX), chilled water or
heat pump for the cooling coil; and electric (SCR), indirect
gas furnace (5:1, 10:1 modulation), hot water, heat pump, or
steam for the heating section;
• Negates the need for defrost cycling under normal
operating conditions, however a defrost mode is available
for extreme combinations of high indoor humidity and low
outdoor ambient temperatures;
• Rooftop units available with a factory-supplied curb;
• Includes AMCA Class 1 (low leakage) internal enthalpy
bypass damper and an unoccupied recirculation damper;
• Includes standard 2-inch MERV 8 filters, however MERV 13,
MERV 14 and 4-inch filters are optional;
• Tested under UL 723 Standard for Surface Burning
Characteristics for Building Materials; and UL 1812 Standard
for Ducted Heat Recovery Systems.
