US-based Thermal Fluid Systems Inc, boast a range of pressurised  pumps, heaters, valves, controls and tanks for oil systems, including the top-end High Pressure Steam Generator (HPSG).

High pressure steam heating systems provide safe vapor phase heat media for operating temperatures up to 600°F. HPSG operate with single users and can maintain very accurate process control temperatures without exposing edible oils to other organic or synthetic fluids.
The ASME Section VIII, Div. 1 design and construction provides National Board Registration for a safe and cost effective alternative to thermal fluid heaters.
Good investment
Standard designs of the HPSG come in vertical configuration with 8 models ranging from 800,000 to 15 MM BTU per hour. The Hermetically-sealed, dual-helical coil, three-pass design and construction maintain 100 per cent X-ray of post-weld heat treatment.
To maintain the necessary heat transfer, the coil surface area is generously sized to protect this good investment. When sizing a heater and designing a system, it is imperative that the heater manufacturer has experience with the thermal fluid intended for use. The foot print of these units are smaller than other similar systems and provides the needed steam for  deodoriser while reducing the space requirements.

Closed-loop system
As shown below, the coil heats the water changing to vapor phase, the steam is then conveyed to user. After the steam gives off its energy to deodoriser, the condensate returns via gravity back to heater in a closed-loop system.
Level, Pressure, and Temperature control and switch prevent vapor lock while providing a safe and cost effective energy source to your deodoriser. No blowdowns, feed-water, pumps, or loss of system heating media make for a non-corrosive, low maintenance system.

Three-pass heater design
The design incorporates a three-pass heater where the first pass is from the burner, combustion products radiate into the main chamber; the second pass - hot gases then travel between the inner and outer coils; the third pass is an additional convection pass is between the outer coil and externally insulated shell.
Thermal Fluid Systems will integrate desired control requirements from basic relay logic to advanced PLC’s using 4-20 mA Input/Output to interface with a plant DCS and touch-screen HMI’s in an enclosure that meets the area classification (NEMA 12, 3R,4, 4X, 7).
Included in all panels are the Burner Managements Controls, motor starters, and all devices. Panels may be designed to meet any FM, GAPS (formerly IRI), NFPA, UL, CSA, and NEMA code requirements. This panel also includes stack temperature monitoring.
Thermal Fluid Systems, from design conception through startup maintains quality control for your heat energy system, and with ASME Code fabrication and UL certified panel shop, provides the assurance of a reliable, trouble-free system that meets applicable regulations .
Thermal Fluid Systems can accommodate most specified burner manufacturers, with standard systems can be fired on natural gas #2 thru #6 fuel oil , propane, and some waste fuel products. They can offer low and ultra-low NOx systems and high turn downs. Fuel Trains are prepiped and can be pre -wired for skid or remote mounting.
Thermal Fluid Systems, Inc. is 'dedicated to providing complete customer satisfaction and meeting the client expectation of quality and support worldwide. We will design and build a heating system that will provide a cost effective solution. We will also assist you in the design of your application by providing a detailed proposal, Mass-Flow Analysis, P&ID, and Layout drawings,' claims the firm.
The firm have also diversified to offer other additional services such as temperature control valves - electric or pneumatic; expansion / drain tanks - customised, ASME and non-coded, with low and high level switch, liquid levels; indicators and inert gas blankets; exhaust Stacks - designed for the stack velocity of your heating system and seismic area requirement for your location; system skid mounting - can be provided as one complete skid-mounted system or in separate skids including control panel, valve trains, tanks, and fuel train; heat exchangers - Skid-mounted steam-generators, hot water heaters, heat exchangers for heating and cooling your process; flue gas recovery - FGR for improved system efficiency and reduced Nox emmissions; economisers and pre-heaters - to further improve system efficiency; secondary loops - from providing simple control valves to engineering complex skids for end-user’s temperature and flow requirements pipe stress analysis; as well as complete design piping, hanger, and system for thermal expansion.
