Palisades State Park is famous for its pink Sioux Quartzite spires. These striking formations include red pipestone, found in only a handful of other locations across the United States, and geologists place their age at 1.2 billion years.
Greenheck now offers low sound condenser fans as a standard offering on its Model RV and RVE pre-engineered packaged rooftop ventilation systems. Condenser fan noise levels can be a challenge with air-cooled packaged rooftop equipment installations. If the equipment is too loud, or placed too close to other buildings, corrective actions are time consuming and costly.
Greenheck’s low sound condenser fans offer a sound power reduction on average of 5-8 decibels when compared to standard condenser fans resulting in perceived sound levels being reduced by up to 50%. An optional electronically commutated motor is also available for increased system efficiency and provides additional sound power reduction at part load conditions.
Greenheck’s Dedicated Outdoor Air System (DOAS) has a unit dedicated to providing cooled, dehumidified fresh air during the summer and heated fresh air in the winter.
Fresh outdoor air is preconditioned by the enthalpy wheel, recovering up to 80% of the energy from the exhaust air, while the coil section further conditions the outdoor air to the desired conditions, combining the benefits of the total energy wheel with supplemental heating and cooling.
Occupying nearly a full city block of the town of Lemmon, South Dakota, the Lemmon Petrified Wood Park is a curiosity of both geology and architecture.
