Evaporative Condenser
NEPTUNE is dedicated to providing the finest industrial and commercial evaporative cooling equipment. Each unit represents the company’s commitment to excellence in engineering and manufacturing. NEPTUNE ‘s emphasis on research in many condenser innovations which have resulted in many major advancements in heat transfer efficiency. The EC line of evaporative condensers represents another example of NEPTUNE ‘s commitment to product development. The line comprises of 12 models ranging in size from 55KW to 550KW.Other sizes can be customized to client’s requirement.
Principle of Operation
The refrigerant vapour to be condensed is circulated through a condensing coil which is continually wetted on the outside by a recirculating water system. Air is simultaneously sucked upward over the coil, causing a small portion of the recirculated water to evaporate. This evaporation removes heat from the coil, cooling and condensing the vapour in the coil.
First Cost
The installed cost of a properly designed evaporative condenser is less than other methods of condensing, such as air cooled or combination cooling tower with separate shell and tube condenser. In addition, their compact design requires less operating space and less supporting steel. Condensers from NEPTUNE utilize a modular design with factory assembled construction to ensure lower field installation costs.
Running Costs
Evaporative condensers reject heat directly to the ambient air in one heat transfer step. The inherent efficiency of evaporative cooling provides lower condensing temperature and compressor power savings of upto 15%. In addition, maintenance costs are minimized through the latest technological advancements in evaporative cooled equipment. These includes a simplified water distribution system, PVC drift eliminators, and many other equipment features pioneered by NEPTUNE.
Quality Construction
Coil Section
NEPTUNE coils feature a design which assures maximum condensing capacity. The airflow through the coil is counterflow to the refrigerant flow providing the most efficient heat transfer process. A special coil design reduces the air pressure drop through the unit, maximizes coil surface area, increases heat transfer capabilities and provides a high film coefficient. The coils are manufactured from high quality steel tubing following the most stringent quality control procedures and then tested at 500 psi air pressure under water to make sure it is leak free. To protect the coil against corrosion, each circuit is sand spray galvanized. The circuits are then assembled into a coil, which is again pressure tested.
Water Distribution Section
The coil must be thoroughly and completely drenched with water at all times, to give the maximum hear transfer and to minimize scalling. The NEPTUNE system does this with specially designed water spray nozzles. The non-corrodable PVC eliminators minimize maintenance and extend the life of the evaporative condenser. A sturdy basin is provided to collect the water before re- circulating it with the help of an pump.
Blower Section
The blower section consists of fans which are constructed from a corrosion free aluminium alloy material for reliable operation and low maintenance. The fan is enclosed in a close fitting, venture shaped cowl for efficient operation. A special stainless steel screen is mounted over the fan discharge for safety purposes.

Refrigerant Condensers
With Plan Tubes and Integrally Finned Tubed Suitable For Halogen and Ammonia Refrigerant
Neptune Condensers An Updated Technology
NEPTUNE CONDENSERS are the normal choice of specialists in refrigeration and Air Conditioning. The condensers carry in them all the latest technological improvements and innovations that have updated integral fin tube condensers. The tube of the condensers are contructed with fixed sheets and are easily replaceable. During construction tube holes in the tube sheets are serrated and the tubes are rolled Expanded / welded into position to ensure elimination of leak in the joints. A wide range of Neptune condensers are manufactured with shell diameters from 150 to 1000 mm and tube length from 1830 to 6100 mm having capacity coverage from 9000 to 7,25,000 Kcal / hr.Our own streamlined manufacturing facilities enable us to design and deliver condensers for special duties whenever required structural steel supports, pressure relief valves, gas and water purge valves, gas inlet liquid outlet flanges are also made available according to requirements.
