How it works

Wide gap welded plate heat exchanger is specially applied in thermal process of medium which contain much solid particles and fiber suspensions or heat-up and cool down of viscous fluid in sugar plant , paper mill, metallurgy, alcohol and chemical industry

Two plate patterns available for wide-gap welded plate heat exchanger, ie. dimple pattern and studded flat pattern. Flow channel is formed between plates which are welded together. Thanks for the unique design of wide gap heat exchanger, it keeps the advantage of high heat transfer efficiency and low pressure drop over other type of exchangers at the same process. 

Moreover, Special design of the heat exchange plate ensures smooth flow of the fluid in the wide gap path. No “dead area”, no deposition or blockage of the solid particles or suspensions, it keeps the fluid go through the exchanger smoothly without clogging.

Application

The wide gap welded plate heat exchangers are used for the slurry heating or cooling which contain solids or fibers, eg.

Sugar plant, pulp & paper, metallurgy, ethanol, oil & gas, chemical industries.

Such as:

☆ Slurry cooler

☆ Quench water cooler

☆ Oil cooler

Structure of plate pack

☆ The channel at one side is formed by spot-welded contact points that between dimple-corrugated plates. Cleaner medium runs in this channel. The channel at the other side is wide gap channel formed between dimple-corrugated plates with no contact points, and high viscous medium or medium containing coarse particles runs in this channel.

☆ The channel at one side is formed by spot-welded contact points that are connected between dimple-corrugated plate and flat plate. Cleaner medium runs in this channel. The channel at the other side is formed between dimple-corrugated plate and flat plate with wide gap and no contact point. The medium containing coarse particles or high viscous medium runs in this channel.

☆ The channel at one side is formed between flat plate and flat plate that welded together with studs. The channel at the other side is formed between flat plates with wide gap, no contact point. Both channels are suitable for high viscous medium or medium containing coarse particles and fiber.
