ADVANCED, HIGH VOLUME NATURAL GAS WATER HEATERS
ACHIEVE REMARKABLE ENERGY EFFICIENCIES.
Traditional natural gas water heating equipment
has for years been recognized as a durable, high
recovery and low cost means of water heating. Now,
thanks to recent advancements in heating equipment,
high volume commercial, institutional and industrial
operations are realizing greater energy efficiencies
than ever before, with large savings on production
New Technologies in Water Heating
example of an entirely new approach to heating
non-potable process water is Kemco Manufacturing’s
Thermefficient-100. This system, designed for a
specific flow rate range and water temperature
rise, effects up to 40% savings in energy costs.
Inlet water enters the heat transfer zone where it is preheated by directly
contacting combustion products from a jet type natural gas burner. As this
interface occurs, heat is extracted to reduce flue gas temperatures to a level
equal or lower than ambient temperature, thereby eliminating stack loss. When
heat transfer achieves the desired temperature, the heated water is collected
at the bottom of the tank and recirculated to the system.
Yet another new approach is Aerco’s indirect-fired system, for heating
both non-potable and potable process water, which achieves thermal efficiencies
of 93% at full load to 99% at 10% capacity. The system features a temperature
control range of 100°F to 200°F, with an accuracy of plus or minus
4°F, and a gas burner designed to modulate in direct proportion to the
load. As a result, the water heater meets varying load demands automatically
without the need for a hot water storage tank.
Benefits of Advance Systems
The Kemco direct-fired water heater, with a thermal
efficiency of close to 100%, is available in a
wide range of BTUH to meet varying operating needs.
New high efficiency designs are considerably smaller
than conventional systems. A 22 million BTUH Kemco
system delivering 375 gallons per minute requires
only 63 square feet of installation space, as compared
to a conventional boiler requiring 200 square feet.
Because it’s direct-fired, start-up time
is eliminated. And since continuous hot water is
supplied, storage tanks are not required.
Aerco’s indirect-fired system, with its highly
efficient heat exchanger and automatically adjusting
burner, eliminates the inefficiencies inherent
in on/off cycling conventional burners. The system combines high capacity with
a compact size, and may be horizontally or vertically vented without requiring
a chimney. The accessibility of the combustion chamber and heat exchanger permit
Kemco and Aerco technologies feature a 750,000
to 15 million BTUH input rating, and a one million
BTUH input rating respectively, and are ideally
suited to applications requiring large volumes
of process hot water.
The Kemco system is finding wide acceptance in the laundry and tanning industries,
as well as in diverse industrial operations such as car washes and food processing.
The Aerco system, with its capability to produce potable water, is found in
hospitals, hotels, restaurants, health clubs, as well as in industrial applications.
These are but two examples of new high efficiency, high volume gas water heaters
