Design Advantages and Benefits

Series HTF and VHTF 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, or near, atmospheric pressure at temperatures as high as 750°F.
	Highly Effective Insulation — shell internally lined with multi-layered ceramic fiber blanket with an average K factor of 0.46.
	Completely Packaged v burner, burner controls and control panel including temperature indicators, pressure switches and fluid-flow protection — all prepiped, wired, and tested for proper, fully- automatic operation.
	Efficient Burner — with forced draft, low-excess air and high-turndown ratio for all commercially available gases or liquid fuels.
	Proportioning Control — to match the range of heat demand. Automatic off-on operation for very low heat load.
	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, sandblasting and application of special coatings for protection against corrosive atmospheres. Many other options available 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.
	Pipe Coil Supports of Stainless Steel — not exposed to radiant heat.
	ASME Code Pipe Coil Construction.
