Hot Water for Concrete

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%

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.

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.

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 System

The 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:

• Solid state auto-tune controller in NEMA 12 enclosure
• Thermocouple temperature probe with bushing (1/4 second reaction time)
• Electro-pneumatic transducer
• 100' of thermocouple and transducer cable
• Quick action positioner for fast valve reaction time
• 2" brass or 3" cast iron 125 lb. blending valve

15,000 Gallon Waste Oil Fired Tank

For the first time in the history of the concrete industry, a hot water heating system has been developed that successfully incorporates a waste oil-fired burner with a unique heat exchanger that enables you to use nearly any type of waste oil instead of #2 fuel oil to produce hot water.

Designed for ease of maintenance as well as optimum performance, the waste oil-fired system is easily incorporated with the standard Infern-O-Therm hot water unit and chiller.  Kits are also available for installation into existing units.

Units available up to 1 million BTU input.
