But that wasn’t all – when tested at a municipal swimming pool, the exchanger removed chloramines from the air. “Its strength,” said Zemmouri, “is the ability to treat pollution at the same time it recuperates energy.” They realised that Terrao’s two-in-one approach would make it ideal for cleaning noxious substances from factory emissions.
Aside from the large projects for BWXT, Southern Air has had a yearly master-agreement contract there for the past five years for maintenance, construction and engineering services. “They are an integral part of the operations here and a very reliable and dependable contractor that we consider part of our team,” says John Compher, BWXT manager of industrial engineering maintenance and construction.
Three years ago, Sutherland designed North America’s first ammonia/CO2 system for the Wells Fargo Sports Complex practice ice rink at University of Alaska’s arena in Anchorage, replacing a leaky direct system with 6,000 lbs (2721.6 kg) of R22. A separate machine house was built for the NH3/CO2 system.
Finally, compatibility among different heating and cooling technologies needs to be addressed. Air handlers with heating and cooling coils can typically be supplied by two differing technologies: chiller or direct expansion (DX) units. Chillers can provide both heating and cooling to the coils and are a very effective way of providing the required capacity with the associated water pump sets.
Given that previous generations of synthetic refrigerants – CFCs, HCFCs and HFCs – have prompted environmental regulations, “it makes no sense to use a fourth-generation synthetic molecule,” said Marc-André Lesmerises, a CO2 refrigeration pioneer who is president and founder of Carnot Refrigeration, Trois-Rivières, Quebec.
Lim noted the lack of any safety standards regarding ROV thermal or fire issues, despite the diverse sources of ignition â debris intrusion, fuel tank integrity, and flammable plastic body panels, for example. Since 2004, ROV manufacturers have launched some 47 recalls for a variety of defects that could result in fires, such as fuel tanks, hoses, and filters; electrical components; and exhaust systems. In addition, the CPSC has launched at least 120 ROV fire In-Depth Investigations since 2004, when the agency began to track this trend.
Keunebrock compares Terrao’s numerous applications to a Swiss army knife. The technology can treat emissions from factories and industrial boilers as well as air in office buildings and shopping malls. It can recycle energy to heat buildings or even cool them, as the company is starting to do in Dubai. Starklab has 10 international patents, and Zemmouri said a Terrao system for private homes should be perfected within three years.

The need for constant care with regards to fire alarm systems in institutional and commercial spaces is an intensely important issue fueled by mandates, supported by fire codes adopted, and enforced by local government, state fire inspectors, insurance companies, and others. Failure to comply can result in unwanted alarms which can invoke fines, penalties, and sometimes non-response, not to mention the padlocking of doors in the event that the Authority Having Jurisdiction (AHJ) deems it necessary.
