Isotex Corporation is a name synonymous with high quality, proven and consistent efficiency and rugged design. Incorporating the latest, most supervisor features, the Unitherm thermic fluid heater has been the best product of its kind, for over 25 years and, with over 2000 successful installations, has made us the leading manufacturer of the thermic fluid heater in India.

TK-E series with Air Pre heater (AH)
0.6 million to 40 million kcal/hr capacity
The first of its kind in India in the higher capacity range, the Unitherm TK-EAH series with air pre heater (AH) has the highest efficiency ever offered at 92% (+ 1%).

The advantages of high combustion efficiency and controlled combustion of world-class duel blocker burner and preheated air has been used to achieved this high efficiency stock
The carefully selected high-quality components and accessories, and the well-monitored manufacturing process, combined with superior technology, have resulted in a fuel-efficient, rugged product, requiring an extremely low maintenance.
These distinguishing features of the Unitherm TK-E AH stems from the advantages enumerated in detail along side.

The Main Heater Advantage
The machine wound coil of ‘Seamless Tubes' manufactured to precise tolerance specifications, ensures a high coil life an a higher heat transfer efficiency.
Unitherm's unique ‘wet back' design further improves efficiency and reduces the refractory material and maintenance in the heat exchanger, resulting in:

1)Higher Thermic Fluid Life
2)Lower maintenance

Horizontal Unit with frontal hinged door, makes for:
1)Convenient operation and maintenance
2) Reduction in maintenance time an cost
3)Easier floor level monitoring

Higher Thermic Fluid flow rate through the coils contributes to:

1) Higher heater coil life
2) Higher thermic fluid life
3) Higher heat transfer at the utilities

Rugged design and construction that enables the unit to perform for years at a consistently high efficiency level.

The air pre-heater forms an integral part of the main heat exchanger which is designed for:

Easy maintenance
Low floor space requirement

The Burner Advantage
Reillo TI Series Dual Block Industrial Burners
These are rugged burners designed for special industrial and commercial application to provide highest combustion efficiency and high component life.

Preheated Air – These burners use air pre-heated up to 150 c and produce total combustion of fuel, thus realizing the maximum heat possible per unit fuel. This contributes tremendously to the efficiency of the Thermic Fluid Heater.

Low Emission Levels – Unique design and Precision manufacturing o burner components results in complete and controlled combustion of fuel, thus producing very low emission levels in the flue gases.

High Turndown Ratio – The Reillo TI Series Dual Block Burners give the highest turndown rations of 5:1

The principle of “load dependant alteration of the combustion head” regulates the air pressure side providing lower excess air quantity leading to better combustion efficiency even at partial loads without any effect of load on combustion efficiency

Simple Maintenance – All components of the burner are logically arranged for simplicity of maintenance. Diffuser, nozzles, ignition electrodes and fuel mixing chamber are easily accessible when the casing cover is opened

The modulating Kit – The modulating controller I suitable for either temperature (c) or pressure modulation (bar) to meet the precise variable system demand.
