Power sector is among the most critical component of infrastructure, crucial for the economic growth and welfare of nations. Power sector is one of the most diversified. Sources of power generation range from conventional sources such as coal, lignite, natural gas, oil, hydro and nuclear power to viable non-conventional sources such as wind, solar, and agricultural and domestic waste.
Reliable and economical electric power has become an essential aspect for normal operation of all elements of developed economies. Hence making the electrical power available at the place of consumer has been a priority for human community, creating new opportunities to develop & monitor the process of power generation &transmission.
In power generation heat exchangers are required for the processes like, heat recovery from the boilers, run away steam &exhausts, condensation of steam, turbine & generator bearing cooling. Positron has provided shell &tube heat exchangers & Air cooled heat exchangers for the required purpose of power generation.
Transmission & distribution involves oil immersed transformers, in which the heat exchangers are used to maintain the oil temperature to safe working levels, oil temperature being a vital factor for the safe & prolong working of transformers. Positron has provided single tube shell &tube heat exchangers, double tube shell &tube heat exchangers & Air cooled heat exchangers for the purpose of power transmission.

This sector provides crude oil, natural gas, and value-added products to major oil and gas refining companies.
Positron offers heat exchangers for critical applications for oil & gas projects. It also provides its customers in the oil and gas industry with a broad range of shell &tube heat exchanger, Air Cooled Heat Exchangers.
In addition to traditional products, Positron also focuses majorly on 20 years tradition of innovation and new product development. It has supplied heat exchangers successfully in various oil &gas plants and giving the desired performance; operating temperatures and pressures and site locations and is extremely reliable.
Hydraulics & Lubrication
Hydraulics is a technology and applied science using engineering, chemistry, and other sciences involving the mechanical properties and use of liquids. Lubrication is the process or technique of using a lubricant to reduce friction and wear and tear in a contact between two surfaces. Fluid-lubricated systems are designed so that the applied load is partially or completely carried by hydrodynamic or hydrostatic pressure, which reduces solid body interactions and consequently friction and wear. In both the above process, the heat is generated as a resultant and hence it is required to expel the heat generated by the equipment during the process, As accumulation of heat may cause the system to malfunction, leading to deterioration of system components and shutdown.
Positron being situated in Belgaum, India’s one of the old hydraulic hubs, has provided heat exchangers to equipment like hydraulic power pack, hydraulic press, & lubrication oil systems. It gets prioritized opportunities in developments & providing solutions for well defined projects in hydraulics & Lubrication.
Marine engineering includes the engineering of boats, ships, oil rigs and any other marine vessel or structure, as well as oceanographic engineering and ocean engineering. Specifically, marine engineering is the discipline of applying engineering sciences, to the development, design, operation and maintenance of watercraft propulsion and on-board systems and oceanographic technology.
The chemical environment faced by heat exchangers is far harsher than nearly anywhere on land. Marine engineers are concerned with surface protection and preventing galvanic corrosion in every project.
Positron has provided heat exchangers to different projects of marine engineering, by using the corrosion resistant materials, supplied by reliable manufacturers for on-board, on-shore & off-shore applications.
Steel industries among the most important industry, and they include the major processes of heat treatment during the production of steel & also gen-sets for power generation. Hence there is a need to manage & stabilize the temperatures at various stages of manufacturing.
Positron has supplied heat exchangers to various processes in steel plant.
Food processing is the transformation of agricultural products into food, or of one form of food into other forms. Food processing includes many forms of processing foods, from grinding grain to make raw flour to home cooking to complex industrial methods used to make convenience foods.
Heat exchangers have long been a vital tool for pasteurization, sterilization, and other food processing needs. And while the technology is mature, there’s still plenty of innovation happening.
Food and beverages are heat treated for several reasons, among which the most frequent and important is to inactivate microbial population and therefore stabilize and prolong shelf life. Heat transfer has to be rapid and effective, in order to avoid as much as possible any damage to nutritive and organoleptic qualities of food, and also to save time and cut down fuelling costs and are important achievements for the food industry.
Besides good heat exchanger design, other factors are of paramount importance to obtain heat transfer efficiency; among them is the avoidance of any debris (either mineral or organic) accumulation on the heat exchanging surfaces.
Positron has supplied the heat exchangers for various processes in the food industry.
The sugar industry subsumes the production, processing and marketing of sugars . Globally, most sugar is extracted from sugar cane and sugar beet. The process includes the requirement of heating &cooling of slurry during the stages of production & also includes gen-sets for the power generation. These create a need of heat exchangers at various stages of production to stabilize & maintain the temperatures (Cooling & Preheating) of feed oil, water, sugar slurry and coal/biogas.
Positron has supplied heat exchangers for various processes of heating, cooling & heat recoveries in the sugar industries.
Heating, ventilation, and air conditioning (HVAC) is the technology of indoor environmental comfort. It’s goal is to provide thermal comfort and acceptable indoor air quality.
HVAC is an important part of residential structures such as single family homes, apartment buildings, hotels and senior living facilities, medium to large industrial and office buildings such as skyscrapers and hospitals, vehicles such as cars, trains, airplanes, ships and submarines, and in marine environments, where safe and healthy building conditions are regulated with respect to temperature and humidity, using fresh air from outdoors.
The three major functions of heating, ventilation, and air conditioning are interrelated, especially with the need to provide thermal comfort and acceptable indoor air quality within reasonable installation, operation, and maintenance costs. HVAC systems can be used in both domestic and commercial environments. HVAC systems can provide ventilation, and maintain pressure relationships between spaces. The means of air delivery and removal from spaces is known as room air distribution.
Positron has provided various heat exchangers in HVAC application.
Pulp & Paper
Pulp & paper industries benefit more than others from specific industrial products or machines.
Without heat exchangers, paper mills would have exceedingly high energy costs, which is bad for the environment as well as the purse size of the paper companies.
Heat recovery is one of the important applications of heat exchangers in this industry as the runaway heat is used to recover water from the moist air, which can be utilized for the purpose of processing. Thus provide economical benefits.
Sewage Water treatment.
Sewage treatment is the process of removing contaminants from municipal wastewater, containing mainly household sewage plus industrial wastewater.
The sludge accumulated in wastewater treatment process must be treated and disposed of in a safe and effective manner. Heat exchangers are used in the process of heating &cooling of sludge during its treatment, such as heat recovery from sludge &raise up sludge temperature before the treatment.
Positron has provided heat exchangers for heating &cooling of sludge in waste water treatment plants.
