INDIRECT HEATING

As the name indicates, in this type of heating, the steam does not come in direct contact with the water to be heated. This type of heating prevents contamination of the water due to steam mixing as in case of direct heating and is used widely in industries where process does not permit such contamination. It is widely used in industry because it provides rapid, even heating. This method uses a heat exchanger, either PHE or shell & tube type, to heat the water.

MWHS can be provided with both plate heat exchangers or shell & tube type heat exchangers based on customer preference.

Package includes pumping trap provided at the condensate outlet of the heat exchanger thereby ensuring zero damage to the heat exchanger under stalling conditions and long working life of the heat exchangers.

DIRECT HEATING

Traditionally a sparge pipe is used whenever steam is required to be directly purged into a water for heating. This gives rise to two kinds of challenges.

High noise due to vibration as steam comes out from a number of small holes and at a high velocity.
As steam comes out at high velocities, a sizable percentage of this steam actually escapes and gets wasted without condensing and mixing with the process fluid..

Compact skid mounted system including tank, thermoject-steam injectors, all required inlet/outlet circulating nozzles and automated with complete steam control instrumentation

Steam is injected using thermoject-steam injectors thereby ensuring zero steam losses, 100% energy utilisation and high energy efficiency due to utilisation of total heat of steam.
