FRANK FHT 155: WORKING RANGE:155-540°C

Heat Transfer Salt for use in large chemical or oil cracking installations in the working range 155-540°C as a heating or cooling medium. In the Moltan state it enables a uniform temperature to be maintained throughout the equipment. Also used to remove the heat evolved by reacting propylene, air and ammonia in a fixed bed reactor for producing Acrylonitrile and HCN Gas. Also used to remove the heat produced by the oxidation of Napthalene in the production of phthalic anhydride used in plant for operating caustic solution to produce solid caustic soda.

​

STABILITY OF FRANK FHT 155:

FRANK FHT 155 is very stable at temperature up to 430°C. Between 430°C and 540°C there is a tendency for FRANK FHT 155 to slowly decompose with the formation of Nitrate, alkali oxide and nitrogen. Also one of the ingredients will be slowly oxidized in the presence of atmospheric oxygen. The later can be avoided by excluding air by protecting the surface of the salt with inert gas, such as nitrogen or argon. There is also a tendency for the formation of a certain amount of Carbonate in the salt by absorption of carbon dioxide during prolonged use. Some carbonate may then be precipitated out of the salt. This is however of little consequence provided the system used is not easily blocked by the deposition of carbonate.

​

FRANK FHT 250: WORKING RANGE:250°C TO 565°C

It  is a Non toxic Moltan heat transfer fluid in the working range 250°C-565°C and can be used in solar thermal applications at very high temperature up to 565°C which is higher than the commercially available fluid . Frank FHT 250 moltan fluid have excellent thermo physical properties in the liquid state with high thermal conductivity.

STABILITY OF FRANK FHT 250 :The maximum operating temperature is 565°C. Beyond this temperature the fluid will evolve into non toxic , inert gases with low vapour pressures and prolonged use of maximum temperature may result solidification.

​

FRANK FHT 140: WORKING RANGE: 140°C TO 485°C

It is a non toxic Moltan salt heat transfer fluid which can be used at high temperature up to 485°C and has a lower melting point resulting extra freeze protection and wider operating  range.Frank FHT 140 Moltan salt fluid have excellent thermo viscosity, high heat capacity, high thermal conductivity. It provides long term heat storage for high temperature applications and provide excellent corrosion resistance to SS material and alloy steel and exibit minimum vapour pressure at peak operating temperature .

STABILITY OF FRANK FHT 140:The Maximum operating Temperature is 485°C beyond this temperature the fluid will evolve into non toxic , inert gases with low vapour pressures and prolonged use of maximum temperature may result solidification.

FRANK FHT 150: WORKING RANGE:150°C TO 450°C

FRANK FHT 150 Moltan salt fluid can be used in hot bath or solar thermal application at high temperature up to 450°C. FRANK FHT 150 has a lower melting point than Frank FHT155, Frank FHT 250 and Frank FHT 140 providing freeze protection and wide operating range.

Moltan salt fluid have required thermo physical properties in the liquid state like low viscosity, high heat capacity and thermal conductivity. Also provides long term heat storage for high temperature application.

​

THERMAL STABILITY: The maximum operating temperature if FRANK FHT 150 is 450°C beyond this temperature the fluid will evolve into non toxic , inert gases with low vapour pressures and prolonged use of maximum temperature may result solidification.
