Thermo Plates (Pillow Plates)

ATHCO-Engineering has a unique knowledge in manufacturing pillow plates and a well-equipped production unit for this exact purpose.

The manufacturing of pillow plates is our principal core competence. We have a unique knowledge, a knowledge that has enabled us to combine pillow plates with our customers' requests for heat exchange.

The unique features of the thermo plates makes them very efficient in heat recovery applications either from exhaust gas, waste water or other “dirty” fluids/ gases.

Heat recovery are not only important for the business’ economy, but also the environment around us. Our pillow plate products are thermal efficient giving a remarkable reduction in your energy consumption meaning production cost reduction and a greener company profile due to lower consumption of fossil fuels. 

 What is a thermo plate (pillow plate)?

A thermo plate (or pillow plate) consists of two plates which are spotwelded together. The plates are sealed with weldings along the contours of the plates. The plate is then expanded until the desired channel height is achieved. The channel height is the maximum space between the two plates.

While the thickness and the spot pattern is determined by the design pressure. The channel height and the space between the pillow plates in a heat exchanger is determined by flow and allowed drop in pressure.
