Heatec HC & HCS Heaters
Heatec HC & HCS heaters are direct fired heaters designed around a helical coil. Our coil meets ASME code. These heaters were originally designed to be used at asphalt plants for mixing road grade asphalt, but because of their versatility they can be found in a number of different facilities for a variety of applications. Their popularity comes from their simplicity, efficiency, low maintenance and relatively low cost. Heat transfer mediums used can be thermal fluid (hot oil), glycol mixtures, or gases. They are also used as process heaters, directly heating the process fluid or gas.
MODELS AND OUTPUTS
Nine standard models are available. Rated thermal outputs range from 0.7 to 4 million Btu per hour. All can be customized to meet your specific needs.
TWO BASIC CONFIGURATIONS
Heatec helical coil heaters are available in two basic configurations: HC and HCS. The HC configuration has a manifold that enables the heater to operate with multiple thermal fluid circuits.

Heatec HC & HCS Efficiency
A hallmark of our helical coil heater is high thermal efficiency. Thermal efficiencies of our standard heaters range up to 85 percent LHV, depending upon fluid outlet temperature and fuel. Thermal efficiency is the total amount of heat produced by the burner versus the portion actually transferred to thermal fluid flowing through the coil. Thus, in our heaters, up to 85 percent of the total heat is transferred to the thermal fluid. Increasing efficiency reduces fuel usage.
Adding a STACKPACK™ heat exchanger (economizer) boosts thermal efficiency another 5 percent. It makes our current heater super-efficient. That extra percentage reduces monthly fuel usage by 261 gallons of No. 2 fuel oil or 345 therms of natural gas. The Stackpack heat exchanger usually pays for itself in a year or less.
Heatec HC & HCS Heater Controls
Heater controls automatically maintain the operating temperature set by the operator. Accuracy is within a half percent of set temperature. Numerous safety features ensure heater operation is always within prescribed limits. Heaters shut down automatically if an abnormal operating condition occurs. Switches and sensors in a limit circuit ensure normal operation. They monitor burner flame, thermal fluid temperature, exhaust gas temperature, flow of thermal fluid, and combustion air pressure. Main controls are in a UL approved NEMA-4 panel
Burner management controls provide proper and safe operation of the burner. They include a display, burner control, programmer, annunciator and flame scanner. The burner control uses a microprocessor for its management functions. The processor provides the proper burner sequencing, ignition and flame monitoring protection. The controls provide important messages about the operating status of the heater. If there is an alarm condition, a message will appear on the display.
Heatec HC & HCS Helical CoilHelical coils in our heaters set us apart from others that produce helical coil heaters for the HMA industry. We are the only heater manufacturer that builds all coils to ASME code. Certification is optional. Coils in HCS heaters have a three year warranty. Coils in HC heaters have a five year warranty.
