Pillow Plates

Pillow Plates are heat exchanger plates that can be used in many ways for the industrial cooling or heating of your product. As the inventor of the laser welding machine for these laser welded plates, Omega Thermo Products has an unprecedented amount of experience in the production of Pillow Plates.
Pillow Plates have endless applications in different industries. Omega Pillow Plates are used for tanks, for example for cooling milk, soft drinks, wine  or beer. But also various other sectors use our plates. For example, the meat processing industry, the chemical industry and the pharmaceutical industry.

What is a Pillow Plate?
A Pillow Plate consists of two stainless steel plates that are welded together by welding spots with a laser welding machine.
At the edges of the Pillow Plate, a contour is welded to create a pressure-tight part. The plates are blown up with water or nitrogen, usually after they have been processed in the final product, to create a hollow space through which the cooling or heating medium can flow. In this way you cool or heat your product with the plates.

Design (single of double embossed)
A Pillow Plate design is always custom-made. At first we look at your desired application. Do you need a plate with pillows on one side and a smooth surface on the other (for example, applications for cooling milk tanks or heat or cool applications in food or the pharmaceutical industry), then choose a single embossed pillow plate. The smooth, flat side is suitable for hygienic surfaces on the inside of the tank. You can do the inflation yourself, our engineers will accompany you.

If you don’t need a smooth side and you want to use both sides of the heat transfer plate, for example because the Pillow Plate is used in a complete cooling or heating installation, you can opt for a plate with pillows on both sides. You will receive the plate inflated and if required, assembled as a complete heat exchanger.
We also process these double embossed plates in our coolers, such as the Falling Film Chiller, Ice Bank, Ice Machine and Immersion Chillers.


  • Cost-effective due to low welding costs
  • Thinner materials can be used, saving you on material costs
  • Pillow Plates' welding pattern guarantees high turbulence and therefore creates high overall heat transfer coefficients
  • Reduced deposition (algae, lime, etc.) due to this higher turbulence (less fouling)
  • Due to the low volume in the plate, little cooling / heating fluid needs to be circulated. As a result, less pump capacity is required
  • By working with laser welding machines that are CNC-programmed, all desired shapes, recesses, fastening points and connections are possible

Which material you need, which thicknesses, spot pattern and pressure, depends on your desired application and capacity. Our engineers are happy to think along with you about the possibilities and are pleased to make a Pillow Plate calculation for you.

We are able to manufacture Pillow Plates from (stainless) steel as:

  • Austenitic material (304, 304L, 316, 316L, 317, 321)
  • (Super) duplex materials (2205, 2507, 2304, LDX-2101)
  • Nickel alloys (Nickel, Hastelloy, Inconel)
  • Titanium

Do you wish to use other materials, please contact one of our engineers.
