American Aldes Zone Register Terminals (ZRT®) are designed to introduce flexibility and dynamic control to central ventilation systems. Used in both large and small systems, the ZRT regulates ventilation without the need for individual fans. Each ZRT is a combination grille, register box, control damper, and optional flow regulator(s). This unique combination provides up to four different control schemes without the need for expensive pneumatic, electronic, or DDC control systems.

By replacing static grilles in large central exhaust systems, the ZRT-1 model provides on-off control for on-demand ventilation. The optional model CAR-II Constant Airflow Regulator can be installed in the ZRT-1’s extended duct collar to place a maximum flow limit on each terminal.

The ZRT-2 model can be used for combination low-flow indoor air quality ventilation and on-demand high-flow spot ventilation, such as a bathroom exhaust fan, using the same central system. This is achieved by integrating a CAR-II minimum airflow controller directly into the damper sub-assembly. With the damper completely closed, the factory calibrated CAR-II will still allow steady, low-continuous ventilation during fan operation. When other ZRT terminals are opened for on-demand control of spot ventilation, the closed ZRT-2s will maintain the specified low continuous rate through the CAR-II minimum flow control. By opening the ZRT-2’s control damper, the low-flow regulator is removed from the air stream, allowing either controlled (optional using a second CAR-II) or full maximum-boost ventilation.

Aldes Zone Register Terminals (ZRTs) provide on-demand boost airflow, typically used in bathrooms and laundry rooms to exhaust humidity and odors. When combined with the optional Constant Airflow Regulator (CAR) they can also be used for continuous low-volume airflow to maintain healthy indoor air. These ZRTs are frequently the preferred ventilation products for high-rise buildings such as apartments, condominiums and hotels.

American Aldes has again partnered with A.D.E. Systems Inc. of New York, to secure the sale of ventilation products—Zone Register Terminals and Constant Airflow Regulators — for a new high-rise condominium along the New York City skyline. With its distinctive curved glass shape, 111 Murray Street is among the newest and most notable projects to date.

The prestigious new condominium, designed by Kohn Pedersen Fox Associates, soars 800 feet with 157 residences priced between $2.5 million and $18.9 million. Residents have access to luxury pools, a fitness center, recreation room, a patisserie, spaces to entertain guests, and of course stunning views of the Manhattan skyline, New York Harbor, and the Hudson River. In a true nod to the level of affluence anticipated at these upscale luxury condominiums, 111 Murray also offers a concierge jet service.

A.D.E. Systems, Inc., the exclusive sales representative for American Aldes products in New York City secured the sale. “A.D.E. Systems has a solid understanding of our products and how they offer value and dependability to the customer while providing healthy indoor air quality,” said Tom Heidel, National Sales Distribution Manager at American Aldes. “This is one of many high profile projects we’ve worked on with A.D.E. Systems over the years and they continue to be a strong partner in matching up customer needs with the best products for the job,” said Heidel.

Other recent projects in which A.D.E and American Aldes have partnered include the Hilton Garden Inn on Park Avenue in Midtown New York, the RIU Plaza, 520 West 28th, the Visionaire Building, 50 West Street, 30 Park Place, 260 Park Avenue South, Greenwich Lane Complex, 313 West 37th Street, W57 Durst, 432 Park Avenue, The Enclave at Cathedral, One Riverside Park and dozens of other properties in New York City and New Jersey.

The deepest geothermal well built to this point is the Kola Superdeep Borehole. It extends more than seven miles into the earth at its deepest point and was used for geological research until the early 1990s.

The most intriguing discovery made by the Kola borehole researchers is undoubtedly the detection of biological activity in rocks more than two billion years old. The clearest evidence of life came in the form of microscopic fossils: the preserved remains of twenty-four species of single-cell marine plants, otherwise known as plankton. Usually, fossils can be found in limestone and silica deposits, but these “microfossils” were encased in organic compounds that remained surprisingly intact despite the extreme pressures and temperatures of the surrounding rock.

While data produced by the Kola drilling project continues to be analyzed, the drilling itself was forced to stop in the early 1990s when unexpectedly high temperatures were encountered. While the temperature gradient conformed to predictions down to a depth of about 10,000 feet, temperatures after this point increased at a higher rate until they reached 180 °C (or 356 °F) at the bottom of the hole. This was a drastic difference from the expected 100 °C (212 °F). Also unexpected was a decrease in rock density after the first 14,800 feet. Beyond this point, the rock had greater porosity and permeability which, paired with the high temperatures, caused the rock to behave more like a plastic than a solid and made drilling near impossible.

A repository of the many core samples can be found in the nickel-mining town of Zapolyarny, about ten kilometers south of the hole. For its ambitious mission and its contributions to geology and biology, the Kola Superdeep Borehole remains one of the most important relics of Soviet-era science.

The first fully air conditioned home was built in 1913 in Minneapolis, Minnesota, by Charles “Bet-A-Million” Gates, heir to a fortune built on barbed wire, railroads and oil. The mansion took up three city lots and had gold plumbing and a full ballroom. Sadly, Gates didn’t live to appreciate this luxury.
