Why Therminol?
Does your process require indirect heating -- that is, high working temperatures delivered to remote ''user" locations without flame? Perhaps your process requires indirect heating and cool ing within the same system. Or, maybe you'd like to get more out ot your process heat by us ing it in a nearby space heating application, as well. There are a number of ways to get these jobs done. A common one involves the use of a pres-

surized heating system -- water (or other liq uids) healed to the vapor phase and transferred under high pressures to the user. But there are drawbacks to this type of indirect heating. Cost ly, often complex equipment, for one. The need for licensed boiler operators for another. Then, too, high operating pressures pose some very real safety problems.
That's Why There's Therminol Heat Transfer Fluids
With Therminol fluids, you discover the best of all indirect heating worlds--high and low heat ranges, thermal stability, and efficient heat trans fer without high pressure, without the need for costly equipment, and without the need for con tinuous observation. Therminol fluid heat sys tems offer you the most dependable, most effici ent indirect heating and cooling your process dollars can buy--and this booklet tells you why.
Several resin kettles with varidus heal reeds can be heated from one Therminol system.
Petroleum processors, both on-shore and ott-shore, enjoy increased heat transfer safely with Therminol.
Rolls in rubber, plastics, textiles and paper get uni form heat with Therminol.
Therminol brings uniform temperature control to tex tile processing and finishing.

What makes Therminol right for your application? Hundreds of customers who have specified Ther minol for new installations and conversions of ex isting systems will give you these answers.
LOWER CAPITAL COSTS | Without pressure you
can save 25% to 50%. That's because you don't
need heavy piping, relief valves or other high
pressure devices.
_
LOWER OPERATING COSTS | Fluid make-up is generally not required. Heat losses are reduced over vapor phase systems because condensate sub cooling is not present. Routine maintenance is minimized and these non-pressured systems re quire only minimum attention by non-licensed per sonnel.

Since Therminol remains liquid throughout its tem perature range, rapid circulation through yoi.r rolls helps achieve uniform heat. This has resulted m greater throughput and fewer rejects lor Therminol customers producing rubber, plastics and paoer

You'll be surprised at how easy it is to work with a Therminol heat transfer sys tem. The middle diagram at the right shows typical* Therminol liquid heating and cooling systems used together to maintain very close temperature control at the user. Note that the term `'heater" is used rather than "boiler" since we do not boil Ihermino! in the primary heal source.
Benefits of a Liquid Heating System
You gain a wide spectrum of benefits with a Therminol liquid heating system.
tn many locations, codes favor Ther minol systems, thus minimizing the need tor expensive operating personnel.
Positive circulation through your users ends venting problems; the system re mains sealed and flooded.
Liquid systems respond more rapidly to your system's load changes.
Install your users at any level in relation to the healer; there's no condensate re moval problem.
You realize a substantial cost savings with smaller pipe. Also, smaller valves control temperature more accurately-- down to .' 2T.
No temperature loss due to pressure drop in the piping; with vapor, any line friction loss results in a lower vapor condensing temperature at tire users.
You can meet different temperature de mands in the same user if required by certain processes by adjusting the cir culation rate.
A liquid heating medium, like Ther minol, will usually give you higher heat transfer rates in certain types of users, such as shell and tube hoat exchangers.
Cooling can be handled in the same system. Heating systems for Therminol are sold around the world on a compet itive basis. Contact your nearest Mon santo office, (listed on the inside back cover) for information and recommen dations on the heating equipment that will fit your particular need.

The Therminol Family
You find more design and engineering flexibility with Therminol than with any other heat transfer media because of the wide range of fluids in the Therminol family.
The Therminol series of heat transfer fluids offer an operating range of 0" to 800F.
Important for the future, as your processes change, you can pick a new Therminol fluid to match your new needs. Most Therminol fluids are interchange able in your liquid heating system.
The charts on the next two pages detail the broad characteristics of the Therminol family of fluids.
On both ships and oargos Therminol preempt lhe high costs of pressurized indirect heating Therminol's ability to recover waste heat adds to the savings.
Low temperature pumpabiUly allows convenient coid weather start ljo, so viscous liquid cargoes are ready for unloading where the vessel reaches port.

Temperature Use Ranges For Therminol Heat Transfer Fluids
F
Therminol heat transfer fluids offer a wide range of operating temperature capa bility. As this bar chart indicates, there is a Therminol fluid for virtually any spe cial temperature situation your process may encounter -- from 0" to 800F. Each Therminol fluid is carefully formulated to bring the best heat transfer prop erties to a given temperature situation. This page and the following will help you select the right Therminol fluid for your application.

Applications Unlimited
The pictures on the preceding pages have given you a glimpse of a few typical Therminol applications. On land and sea. In plants and apartment buildings.
But the applications for Therminol are actually unlimited. As unlimited as your needs for safe, uniform, efficient heat delivery.
Here are a few more areas where Therminol has met those needs:
CHEMICAL PROCESSING . . especially where flammable materials are handled. Therminol has proved particularly success ful for exchangers, distillation columns, rcboilers, mixers, dryers, etc.
RESIN PROCESSING . . . where a single
"circuit" with multiple users and varying
temperatures is desirable.
-
PLASTICS, RUBBER MOLDING AND PAPER . . . where uniform heating, rapid temperature flux and pin-point control is essential such as heating corrugating and drying rolls, crimping presses, calendars, platens and molds.
TEXTILES PROCESSING ... for con trolled temperatures in processing and finishing of synthetic fibers.
PETROLEUM AND OfT-SKOI;:. DRILL ING . . .offers control over a wide tem perature range and the ability to accom modate sudden fluctuations in processing loads automated with complete safety.
SHIPS AND BARGES . . . preempts the cost of pressurized indirect heating sys tems with efficient, dependable heating while underway.
SPACE HEATING . . . ideal for hospitals, hotels, apartment houses and office build ings where the goal is safety, low main tenance and reduced operating costs.
