Superior heat transfer characteristics and cost savings through custom-made designs!
Over 25 years experience in heat transfer technology
Several designs possible, such as single- and double embossed OMEGA-PillowPlate ®


PillowPlate advantages

  • Superior heat transfer.
  • High turbulence with low velocities due to OMEGA-plate design.
  • Even distribution of cooling and/or heating media.
  • Lower operating cost.
  • Reduced fabrication cost.
  • Improved control characteristics due to low volume.
  • Design suitable for complex geometries.

Single embossed PillowPlate 

OMEGA-plate single embossed is mostly used for applications where one side of the plate needs to be flat and smooth. For example, tank walls or heat exchanging surfaces for the food and pharmaceutical industry. One significant advantage of this application is that due to the controlled heat input and weld depth from laser welding, no heat tint will appear on the product contact side of the vessel wall. In fact, the protective foil is left in place and remains intact after welding. 

Single emboosed PillowPlate ®

Double embossed PillowPlate

OMEGA-plate double embossed is generally used when a smooth, flat surface is not required. Examples for this application are heat transfer surfaces in complete assemblies, such as plate banks for cooling or heating, falling film water chillers, ice machines, heat recovery banks, etc.

PillowPlate specifications

OMEGA-plate can be manufactured from most stainless steel materials, such as 304, 316, 3116Ti, 321, SAF2205, LDX-2101, Hastelloy and Titanium. Other materials can be laser welded upon request.

The choice of surface finish is up to the customer. Our OMEGA-plates can be supplied in various finishes, such as cold rolled 2B, 2E, 2BB or 2R.

The machines are flexible in handling various dimensions, up to a maximum width of 2 meters, and a maximum length of 14 meters.
