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.

Advantages

• 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”)

Industrial Ice Machine

Our Industrial Ice Machines are used in many different industries. If you need large quantities of ice to cool your products, our Ice Machine is a good solution. By using Omega Laser Plates, you will get a machine that is relatively small in size and is easy to maintain. Based on your needs, we run heat transfer calculations to see which capacity of Ice Machine you need. Our Ice Machines are always custom-made and designed to your specification. 

How does an Ice Machine work?

At the top of the Ice Machine, water is pumped in and falls through small holes then slowly flows down the Omega Laser Plates. The coolant in the Laser Plates cools the water down until it is frozen. When the ice on both sides of the plate is approximately 3/16” to 3/8” thick, then hot gas is injected into the Laser Plates, causing the plates to warm up and release the ice from the plates. The ice falls into a storage tank and breaks into smaller pieces. This ice can be transported by a transport screw to the desired location.

Advantages

• No moving parts which means maintenance is minimal
• Low energy consumption
• High ice production for such a small machine
• Easy to keep clean
