Thermal Fluid Heaters

Horizontal and Vertical

For High Temperature Heat Transfer Systems

DESIGN ADVANTAGES
AND BENEFITS

Model VHC or HHC Helical Coil
Thermal Fluid Heaters

	Two-Pass Design — radiant- and convection-pass for efficient operation.
	High Temperatures with Low Pressures — First Thermal Heaters Heaters can operate at atmospheric pressure at temperatures as high as 750°F. (A pressure of more than 3000 lbs. would be required to produce the same temperature with steam.)
	Coil Constructed to ASME Code.
	Structural Steel Supports — welded in accordance with AWS requirements.
	Coil Supports of Stainless Steel — not exposed to radiant heat.
	Highly Effective Insulation — shell internally lined with multi-layered ceramic fiber blanket with an average K factor of 0.46 at operating temperatures.
	Completely Packaged — burner, burner controls and control panel including temperature indicators, pressure switches and fluid-flow protection — all prepiped, wired, and factory-tested for proper, fully-automatic operation.
	Efficient Burner — with forced draft, low-excess air and high-turndown ratio. Available for all commercial gases or liquid fuels.
	Proportioning Control — to match normal range of heat demand. Automatic off-on operation for extremely low heat demand conditions.
	Control Panel — with full programming combustion safe-guard (ultra-violet detection), fluid temperature and pressure controls, motor starters, relays, operating switches and lights to indicate operating conditions. NEMA 1 (standard) with optional NEMA ratings available for any need.
	Low Maintenance and Long Life — thermal fluid does not cause scale or corrosion.
	Conservative Design — increases equipment life and reduces downtime.
	Factory-Trained Service Personnel — available for start-up, operator training and fast emergency service.
	Computer Design — for each job for proper flux, film, and tubewall temperatures, velocity, delta t and delta p to stay well within the limitations of the thermal fluid and materials of construction for long fluid life and to fit your system requirements.
	Special Controls and Construction Options — include systems to meet FM or IRI insurance requirements or other insurance or customer standards, burner management systems incorporating PLC's, seal welding of shell and piping, sandblasting of shell and piping and applying special coatings for protection against corrosive atmospheres and many other options to meet your system requirements.
	Limited 5-Year Coil Warranty — is available on First Thermal Heaters for most applications thus providing you with financial protection that isn't available from most manufacturers.
