Hot Water for Concrete
HW SERIES
The Infern-O-Therm HW-Series hot water storage systems are designed
for heating and storing water for concrete
manufacturing during the cold seasons. These systems are also useful
for applications where large volumes of heated water are required.

million BTU input

The HW-Series offer a wide range of standard tank sizes from 3,000
gallons to 35,000 gallons. The highly efficient Infern-O-Therm combustion
system provides extremely fast recovery rates--minimizing waiting
times and optimizing on-the-job mixer availability. It also ensures
optimum fuel burn rates--meeting your bottom line and environmental
concerns.
Efficient Combustion System
The unique design of the HW-Series combustion system reduces heating
costs up to 50% compared to other heating methods. It provides the
precise, chemically-correct combination of fuel and air to heat water
at the lowest possible cost. A patented, CLOVERLEAF super-charger
within the combustion chamber refocuses air and fuel from the primary
chamber to ensure combustion efficiencies over 90%

Heat Transfer System
Primary and secondary heat transfer tubes are designed to provide
maximum fuel efficiency during the heating process. The combustion
tube is fabricated from seamless steel pipe for optimum heat transfer
and minimum maintenance. Infern-O-Therm's unique sprinkling system
offers a uniform distribution of water and integration of cold water
into hot--eliminating costly cold spots. The HW hot water heating
and storage systems by Infern-O-Therm offer a low-cost, highly efficient
method of producing and storing large volumes of hot water for concrete
manufacturing and other similar applications. For more information
or a quotation, contact your local dealer or Infern-O-Therm today.

State-Of-The-Art Burner Control
The burner control system of all HW models is designed for simple
operation and minimal maintenance. it is fully automatic with aquastatic
temperature control and high-low water cut-offs. Inlet water is regulated
by a flow control manifold to maintain constant temperature. The standard
model is designed to work with number two fuel, but may be easily
modified to burn natural gas or propane. The entire burner system
utilizes brand name components. A weatherproof enclosure protecting
the burner system is standard equipment on all HW models.

Water Temperature Blending SystemThe Temperature Control System for
hot and cold concrete production is the latest technology in highly
accurate and responsive water temperature control. This system
enables the user to select the exact water temperature needed.
The system features the ability to react to temperature changes 4
times a second with a plus or minus 0.3% accuracy.
The Temperature Control System helps to increase the efficiency of
either your heating or cooling equipment. Blending in ambient
water to achieve the exact temperature required, reducing the load on
your heater or chiller.
The Temperature Control System includes the following:
