MARINE HEAT EXCHANGER
Marine grade header tank heat exchangers are designed for use with aggressive cooling media such as seawater. The specification includes cupro-nickel or titanium tube stacks and a choice of corrosion-resistant end covers for long-life reliability, We provide one of the widest range of engine jacket water heat exchangers available.
KEY CHARACTERISTICS
- Square Type Cooling System consists of quality Honey comb PVC fills to maximizes economy eliminators in a design for efficiency directly driven fan Minimum drift Losses due to Motor with spray Nozzles.
- Hot dipped Galvanized hardware with rectangular casing body in elegant design.
- The towers come with fixed headers and splash nozzles which help in distributing water over the fills.
- This cooling tower makes it durable and reliable regardless of the weather condition.

FRP CASING
The F. R. P. cooling tower casing has sufficient strength to adequately withstand Wind velocities up to 60m/sec. (134 mph), earthquakes and vibrations.
FRP BASIN
The water basin like the tower casing is made of FRP. It is bowl shaped, with a cylindrical auxiliary suction tank at the bottom. This construction eliminates the danger of drawing air into the pump when operating with minimum water in the basin. A drain is provided to facilitate the removal if accumulated dirt from the bottom of the tank. The bowl shape of the water basin facilitates the cleaning of the tower interior.
PVC FILLS
The fillings are made of PVC.They have excellent heat exchange efficiency & remarkably good chemical resistance. These fills are totally enclosed in the tower, thus excluding them from sunlight and minimizing the growth of algae.A pre-eminent quality and long life fill consists of modular block of PVC honey combs construction to create prolonged contact time of hot air with water for maximum heat transfer.
HEADER PIPE
The Header pipes are used for co-current water distribution systems. Air and water both travel together in the same direction from top to bottom. Hot water is allowed to spray through specially designed nylon/pp nozzles at minimum 0.5 kg./ sq. cm pressure. Water enters nozzle tangentially at top and is given spiral action in spiral chamber.
SPRAY NOZZLES
The performance of cooling tower greatly depends upon the water distribution over the fills. The nozzles distribute water evenly through a wide spray angle without any dry pockets. They are lightweight and reduce the frequency of clogging. The Solid Cone Square Pattern nozzles produce a solid cone spray of water that is Distributed in a square pattern onto the fills.
DRIFT ELIMINATOR
Reduces carry over losses of water. The eliminator is of rigid PVC (Applicable for square type cooling tower). The individual drift eliminators of S-shaped corrugated sheets are bonded with subsequent layers to create the structure. The entire area is thus divided into several fine S shaped mini zones each removing water droplets on the entire surface of the cell.
ALUMINIUM / FRP AXIAL FAN
Specially designed energy efficient fans are of induced-draft axial type with adjustable pitch. Material chosen arenon corrosive of plastic, FRP or aluminium alloy. The high efficiency design ensures low running cost and the lowest possible noise level. Fan blade pitch is factory set and dynamically balanced.
COOLING TOWER MOTOR
The motors are totally enclosed (IP55), flange type, 415 V, 3 ph, 50 Hz, induction weather proof with SS304 extended shaft and are specially designed for cooling tower application.
COOLING TOWER MOTORIZED GEAR BOX
This gearbox series for cooling towers and/or pulp and paper mixers is especially built to grant reliability to customers. This is made possible through a generous upsizing of both gears and bearings as well as a balanced internal gear arrangement, so to offeroptimization of uniformity in balancing loads inside the gearbox. With the half casing the periodic inspection and maintenance purposes are facilitated, especially in places that are not easy to access.
