Pulse Of The Heat Exchanger

ROLL BOND EVAPORATOR

At KRN Heat Exchanger & Refrigeration Ltd., we manufacture Roll Bond Evaporators – a highly efficient and compact cooling solution for domestic refrigerators, freezers, and commercial appliances. Produced by bonding two aluminum sheets together through a pressure rolling process, these evaporators feature internal refrigerant channels for uniform cooling, high durability, and superior energy efficiency.

Lightweight and space-saving, Roll Bond Evaporators provide excellent thermal conductivity, making them the preferred choice for modern refrigeration systems.
