Radiator

Landhi Engineering Works (Pvt) Ltd (LEW) was established in 1972.  The company launched Radiator Cores and Assemblies in the market in 1994.

Landhi Engineering Works (Pvt.) Ltd. is the Largest Manufacturer of  Radiator Cores & Radiator Assemblies for all type of Vehicles. We are the regular Vendor for OEM ( Original Equipment Manufacturer) and supplying Radiators to Massey Ferguson, Fiat & Combined New Holland for their Farm Tractors & Isuzu, Nissan, Daewoo, Kia for their Buses, Truck, Tractor & Cars.

Our Radiator Plant is equipped with World’s most advanced radiator plant equipment manufacturer “M/s. Tooling & Development”, England. We import Raw Material Copper , Brass & Solder from Sweden, Netherlands & Dubai respectively. We have different varieties of products in Straight Fins & different varieties in Zig Zag Fins Types.  We have the capability to manufacture max. 58” x 58” in One piece for Big Size Generators.

Our Range of Radiator

About 3G Radiator

We have Latest and most advanced Technology called "3G, Third Generation" having the most cooling efficiency and Heat Transfer Area. 3G (Third Generation) RADIATOR means “EFFICIENT RADIATOR” a radiator, which provides EXTRA COOLING HEAT DISSIPATION.

How it Provides Extra Heat Dissipation!

There are number of improvements in 3G RADIATOR which are given below:
Increased tube width
Minimum fin slant height
Fine pitch of windows per FIN.
Dual direction & aerodynamic design of fin windows, which dissipates heat from all the sides of tube.
Increased surface area of heat dissipation
Higher fins, tubes density which in turns give rapid heat transfer per unit frontal area.
Increased volume of coolant.

Engineering Equipments

Tube Machine Features:

Tube Machine Features:

Pre-knurling and locking system, which helps to control leakage.
It also has very suitable tube width i.e. 1.6mm, which helps to increase number of tubes and results in increase cooling effect.
It's design gives maximum contact areas for fin.
Each tube is solder sealed during forming process.

Fin Machine Features:

Fin Machine Features:

Fin has two direction windows, which help air to circulate in all direction.
Fin also has fine pitch windows, which help to contact maximum areas of tube causing cooling effect.
Suitable fin slant height which helps to increase number of tubes and hence more cooling .

Pneumatic Airway Assembly:

Pneumatic Airway Assembly:

Quick Change over between different types of cores.
All fitments by pneumatic cylinders & controllers
Dimensional accuracy of core.

Pneumatic Pressure Leak Test:

Pneumatic Pressure Leak Test:

100% accurate result found in radiator leak testing.
It can test radiator at high pressure to account for factor of safety as per design pressure of cooling system

Temperature controlled baking Oven:

Temperature controlled baking Oven:

It gives accurate and strong bonding of tubes and fins.
It is totally pneumatically controlled.

Temperature controlled header plate solder bath:

Temperature controlled header plate solder bath:

Gives good coating of solder at header plate hence leakage free.

Testing of Radiator:

Testing of Radiator:

Vibration testing machine.
Drop testing machine.

Heavy Duty Radiator Facility in Straight Fin:

Heavy Duty Radiator Facility in Straight Fin:

It gives more tubes in same width if radiator compared with conventional strength fin Radiators.
More volume of water.
