We are engaged in the manufacture and sale of air conditioning and heating
equipment consisting of rooftop units, chillers, packaged outdoor mechanical
rooms, air handling units, makeup air units, energy recovery units, condensing
units, geothermal heat pumps, self-contained units and coils.
Our products serve the commercial and industrial new construction and replacement
markets.
Our rooftop and condensing unit markets primarily consist of units installed
on commercial or industrial structures of generally less than ten stories in
height. Our air handling units, self-contained units, chillers, packaged outdoor
mechanical rooms and coils are applicable to all sizes of commercial and industrial
buildings.
The size of these markets is determined primarily by the number of commercial
and industrial building completions. The replacement market consists of products
installed to replace existing units/components that are worn or damaged. Currently,
slightly over half of the industrys market consists of replacement units.
The commercial and industrial new construction market is subject to cyclical
fluctuations in that it is generally tied to housing starts, but has a lag factor
of six to 18 months. Housing starts, in turn, are affected by such factors as
interest rates, the state of the economy, population growth and the relative
age of the population. When new construction is down, we emphasize the replacement
market.
We purchase certain components, fabricate sheet metal and tubing and then assemble
and test the finished products. Our primary finished products consist of a single
unit system containing heating and cooling in a self-contained cabinet, referred
to in the industry as "unitary products”. Our other finished products
are chillers, packaged outdoor mechanical rooms, coils, air handling units,
condensing units, makeup air units, energy recovery units, rooftop units and
geothermal heat pumps.
We offer three groups of rooftop units: the RQ Series, consisting of five cooling
sizes ranging from two to six tons; the RN Series, offered in 27 cooling sizes
ranging from six to 140 tons; and the RL Series, which is offered in 21 cooling
sizes ranging from 45 to 240 tons.
We also offer the SA, SB and M2 Series as indoor packaged, water-cooled or
geothermal/water-source heat pump self-contained units with cooling capacities
of three to 70 tons.
We manufacture a LF Series chiller, air-cooled, a LN Series chiller, air-cooled,
and a LZ Series chiller and packaged outdoor mechanical room, which are available
in both air-cooled condensing and evaporative-cooled configurations, covering
a range of four to 540 tons. BL Series boiler outdoor mechanical rooms are also
available with 400-6,000 MBH heating capacity. FZ Series fluid cooler outdoor
mechanical rooms are also available with a range of 50 to 450 tons.
We offer four groups of condensing units: the CB Series, two to five tons;
the CF Series, two to 70 tons; the CN Series, 55 to 140 tons; and the CL Series,
45 to 230 tons.
Our air handling units consist of the indoor F1, H3 and V3 Series and the modular
M2 and M3 Series, as well as air handling unit configurations of the RQ, RN,
RL and SA Series units.
Our energy recovery option applicable to our RQ, RN and RL units, as well as
our V3, M2 and M3 Series air handling units, respond to the U.S. Clean Air Act
mandate to increase fresh air in commercial structures. Our products are designed
to compete on the higher quality end of standardized products.
Performance characteristics of our products range in cooling capacity from
two to 540 tons and in heating capacity from 69,000 to 9,000,000 BTUs. All of
our products meet the Department of Energys (“DOE”) minimum efficiency
standards, which define the maximum amount of energy to be used in producing
a given amount of cooling. Many of our units far exceed these minimum standards
and are among the highest efficiency units currently available
