Sectional heater

Sectional heater (heat exchanger)


It is designed to heat products of sugar production during sugar beet and raw sugar processing. According to the type of heating medium are divided into heaters - using vapour as heating medium, and – heat exchangers – using condensates as heating medium.

It is used for heating of almost all kinds of sugar industry products (except outflows of crystallization station), and is also broadly used in other branches of sugar industry and heating systems and systems of hot water supply.

There are designed more than 70 standard sizes of heaters and heat exchangers which satisfy needs of plants with productivity from 2 000 to 10 000 t of beet processing per day.

Structural features

Possible number of sections from 2 to 8.

Standard sizes are almost unlimited. High efficiency system of condensate and non-condensed gases discharge, supply of heating vapour.

Optimal correspondence of heating surface with product’s speed and hydraulic resistance.

Possibility to manufacture taking into account specific conditions of each plant, different variants of arrangement depending on characteristics of location.

Heat exchange surface is made of stainless tube.



The most balanced correlation of price/efficiency in comparison with other types of heaters (heat exchangers).

Full use of ammonia condensates.

Stepped cooling of ammonia condensates to the temperatures required for technological consumers and for extraction units feeding.

Prevention of stagnation zones formation and maximal use of heating surface due to the system of heating vapour supply and non-condensed gas discharge.

Providing the maximal use of heat transfer mediums energy including low-grade (temperature of the heating vapour starting from 48-50°).

Maximal heat transfer coefficient due to horizontal arrangement of the heaters, which use low-grade vapour (massecuite, secondary vapour of evaporation station’s V body).



Minimal scale deposit at the heat exchange surface due to optimization of products’ velocity.

Uninterrupted operation during the whole production time.

No compound and expensive elements.



Evaporation station evaporative capacity increasing due to use of high heat exchange coefficient heaters if using low-grade vapour.

Reduction of vapour consumption on technological needs.

Reduction of water consumption on vacuum-condensate plant.

Broad possibilities for heat technology scheme improvement towards economy of heat and power resources and reduction of environmental emissions accordingly.
