New Products
Noritz Combination Boiler
Noritz has expanded its line of combination
boilers with the new Noritz Residential
Combination Boiler (NRCB),
which allows for simultaneous residential
domestic hot water and space
heating and performs at a 95% AFUE
(Annual Fuel Utilization Efficiency).
The NRCB is available in two models:
the NRCB180DV has a maximum gas
input Btuh of 180,000 for hot water
and 100,000 Btuh for space heating. Its
maximum flow rate is 9.8 gallons per
minute (gpm); and the NRCB199DV, with a maximum gas
input Btuh of 199,000 for hot water and 120,000 Btuh for
space heating. Its maximum flow rate is 11.1 gpm.
Vertical Design
After several years of offering its S-Series heater in
custom vertical configurations to meet specific customer
needs, Cambridge Engineering has standardized the
vertical design in three different sizes, along with vertical
mounting stands to make installation easier. The S-Series
is an HTHV (high temperature heating and ventilation)
direct gas-fired space heater that is 40%-70 % more
energy efficient than other types of indirect and direct gasfired
systems used to heat large commercial and indus-
trial buildings, according to the company.
Installation choices now include horizontal
thru-wall, rooftop, and under roof; and
vertical outdoor and indoor. The S-Series
is easy to install and start-up because it is
compact, lightweight, pre-piped and prewired.
The vertical stands now also come
standard to make installation faster for
contractors.
The new standard vertical heaters are
available on three models: S-1850, S-2200,
and S-3200. Heating capacities are, respectively:
1.8, 2.2, and 3.2 MBtuh.
Flue Gas Analyzer
Wohler USA introduced the Wohler
A 450 Flue Gas Analyzer, offering
measurement and tuning functions.
The analyzer is affordably priced and
has rugged, yet compact, housing, a
touch screen monitor and advanced
sensor technology. It provides the
flexibility for applications such as checking furnace efficiency,
boiler tuning and water heater checks. It also
offers transmission of all measurement data to a mobile
device (smart-phones, tablets by Android and iOS) per
Wireless LAN.
