Omega's Falling Film Water Chillers

The Omega Falling Film Chiller is a water cooler based on Laser Plate technology. With the ability to cool water down to 33F. From a Falling Film Chiller you can cool large amounts of product in a short period of time. This (recirculating) water cooler, which cools the water at a constant temperature, is a suitable solution for the continuous cooling of many products.
Because every cooling requirement is different, our Falling Film Chillers are always custom-made. Together with our engineers, we will calculate the best solution for you.

What is a Falling Film Chiller?
A Falling Film Chiller is a heat exchanger that cools water to your desired temperature. This cold water is used to cool large quantities of product in a short amount of time, for example, to blanch vegetables or to mix with concrete to prevent the concrete from drying too quickly.

You can also choose to recirculate the water and let Omega Laser Plates cool the water down again to the right temperature. With this recirculating Falling Film Chiller your products are continuously cooled to an even temperature.

How does a Falling Film Chiller work?
In the upper cabinet there is a water distribution pan with multiple holes on the bottom that the water will exit the pan through and flow over our double embossed Laser Plates hanging underneath. A thin layer of water falls over the plate and is cooled to the desired temperature. The water can be cooled to 33 °F with a Falling Film Chiller.

This cooled water falls off the plates into an optional tank and from there can be pumped and distributed to the next process whether that be another heat exchanger, process tank, or food product. The used water can be collected in a reservoir and pumped back to the top of the Falling Film Chiller for the process to start over again.


  • Efficient cooling to very low temperatures (33 F) without the risk of freezing
  • Consistent temperature of the chilled water
  • Custom-made to your needs
  • Easy to maintain open construction. Occasional cleaning with high pressure
  • Fully constructed of stainless steel
  • Can cool slightly polluted water (particles smaller than 5/16”)

All our Falling Film Chillers are custom-made. Together with an engineer, we discuss your needs to cool and the right capacity. 

Depending on your expectations, our coolers can be produced with a capacity of 2.5 to 7500 tons of refrigeration per unit.
The water can be cooled over a wide temperature range: ΔT 85 °F is possible with re-circulation.

Cooling medium
Almost all cooling media can be used with this Falling Film Chiller, such as R717, CO2, Propylene glycol, Ethylene glycol, R22, R134A and R404A.
If you want to use other cooling mediums, please email our engineers.

The Falling Film Chiller is made of stainless steel, such as 304, 316, SMO-254 and Duplex 2205. If you want a cooler made of a different material, please email our engineers.

In many production processes where the cooling of large quantities of product is required, the Omega Falling Film Chiller is a solution.
Examples of where our coolers are used are:
