Nation’s First LEED® Platinum Pool Features
State-of-the-Art DECTRON Systems

A funny thing happened on the way to designing a green project; the design team racks up 53 LEED credits and goes for LEED® Platinum.

Philadelphia, Pa. — Philadelphia’s Kappen Aquatic Center at the Overbrook School for the  Blind (OSB) is the nation’s first LEED® platinum natatorium. Ironically however, the $11 million project for OSB’s 200 visually impaired and handicapped children wasn’t conceived as a LEED® project.

World’s First Natatorium CFD Analysis Helps Tame Wild
HVAC Design Variables of Huge High School Indoor Pool.

Holland, Michigan — Natatoriums can be considered one of the HVAC industry’s most challenging design  applications, due mainly to their huge evaporative rates. Consequently, the world’s first natatorium Computational Fluid Dynamics (CFD) analysis service was an extremely valuable and welcome tool available when designing the huge 16,500- square-foot natatorium of East Kentwood High School, in Grand Rapids, Mich.

Rahway YMCA HVAC Retrofit
Cuts Energy Costs While Adding A/C and Free Pool Water Heating

Engineer specifies new A/C and Dehumidification, as well as
Space Heating and Pool Water Heating – All from a packaged HVAC unit.

Rahway, N.J. — The most common complaint of swimmers entering a pool is “cold”  water, but summertime swimmers at the Rahway Branch YMCA, Rahway, N.J., regularly voiced criticism that the 200,000-gallon indoor pool was too hot.

YMCA Saves Costs with Custom HVAC Equipment and
Value Engineering

Heat recovery for pool water heating, fabric ductwork for airflow alternatives, and HVAC equipment modifications add up to savings.

Plainfield, Ill. — Client requests for state-of-the-art energy efficiency and value engineering of the HVAC systems at the C.W. Avery Family YMCA produced ingenious “outside the box” innovations. The 52,000-square-foot facility had the watchful eyes of a generous donor, plus the high profile status as the first YMCA internationally to be a collaborative effort between a school board, a hospital, a city, and a park district.

Dehumidification Needed in the Desert?

You Better Believe It!

Energy-saving heat recovery design prompts desert town to abandon controlling indoor pool humidity with 10-percent RH outside air.

Taos, N.M. – The idea of using year-round dry outside air of the New Mexico desert to reverse the high humidity loads of a huge 13,000-square-foot indoor swimming pool building sounds logical, in theory. However, the chilling evaporative effects that dry 10-percent relative humidity (RH) air has on a swimmer's body at a local facility employing this strategy confirms that other methods are required. When city officials of Taos, a resort community in the northern high plains desert of New Mexico, floated the idea of saving on indoor pool mechanical dehumidification costs on the new $3.1-million Youth and Family Center, they were persuaded otherwise.

Custom Design Offers Huge HVAC Operational Savings
at the Mizzou Rec Center

Custom configuration specifications on natatorium dehumidifiers
will save the University of Missouri millions of dollars
in operating costs over the life of the building.

Columbia, Mo. — Visitors to the new $49-million Rothwell-Brewer Student Recreation Center Complex are usually in awe of one of the nation’s top five recreation projects and Missouri’s largest aquatic complex. Equally awesome is the behind-the-scenes energy savings that has been built into the state-of-the-art project, which will save the University of Missouri millions of dollars in operating costs over the life of the center’s dual natatoriums.

Sewage Odor Control System for Pumping Station

A two-fold requirement providing neighbors with an odorless environment, and providing pumping station operators with ventilation to keep the inside hydrogen sulphide steady state concentrations below toxic levels when the wells are serviced for maintenance.

In Hong Kong, land comes at a premium.  Placing sewage pumping stations in the city or at the outer regions becomes a major engineering task, as very expensive housing complexes or commercial buildings share the same property line as sewage pumping stations.

One of the World's Largest Dehumidifiers Hoisted into
Hilton Hotel Fun Center.

Rigging the 30-foot-long DRY-O-TRON® challenges contractor, but, specifying a one-piece unit cuts costs on the $40 million expansion.

Milwaukee — Hoisting a 30-foot-long, 20,000-pound DRY-O-TRON® dehumidifier sideways into the semi-completed $40-million Hilton Milwaukee City Center expansion was a rigging challenge for mechanical contractor, Downey Inc., and general contractor, Mortensen Construction.

Resort's Four-Season Pool and Spa Paradise in Canadian Mountains Features State-of-the-Art HVAC System

IAQ, energy efficiency and moisture removal are combined for
indoor mountain fantasy.

Mont Tremblant, Quebec—Half of the swimming experience in the new 30,500-square-foot aqua club at the four-season resort in Mont Tremblant, Quebec, is a breathtaking view of the Laurentian mountain range.

However, without a state-of-the-art HVAC system for Tremblant’s newly-built, $4 million AquaClub La Source—owned by IntraWest Corp.,Vancouver, B.C.—the vast 150 linear feet of windows revealing this picturesque scene would be covered with a blurry surface of condensation.

HVAC Equipment Selection for New Developments by Erickson Carries a Unique Criterion:  If it is the Industry's Latest High Efficiency Equipment, Erickson Wants It.

At Ann’s Choice, the efficiency and indoor air comfort were increased by water source heat pump methodology by adding
DRY-O-TRON® make-up air units.

Warminster, Penn. — Erickson, a Baltimore, Maryland-based national developer/manager of
campuses for middle-income individuals and families over the age of 62, consistently chooses technically superior, high-efficiency, and space saving equipment over price for its communities. In the long term, this strategy delivers the optimum indoor air comfort, generates continual energy savings for residents, and helps preserve the environment.  In addition, the space saving aspects help offset the difference between this custom-manufactured equipment and off-theshelf equipment.
