Falling Film Chiller

Falling Film Chiller Process reliability to produce constant cooling of ice water (0.5°C) near freezing point

Falling Film Chiller or so-called baudelot ice water cooler are mainly designed for cooling water down to 0.5°C near freezing point. What makes the falling-film chiller so interesting is its relatively simple operation. 

Especially Ice water (0.5°) has a very good heat capacity, i.e. by contrast with other cooling agents, relatively small quantities can convey a large amount of heat. The flow-specific and thermodynamic parameters of water are favorable, so that high heat transfer rates can be achieved. Above all, temperatures achievable in the water are made to approach the zero point as closely as possible in order to exploit maximum temperature differences for the products to be chilled with ice water and to keep the temperature of the cooled product as low as possible.

• No risk of freezing with ice water of 0.5 ° C
• Water cooling rom water 35°C to 0.5°C in one step
• Heat transfer coefficient up to 2000 W/m2 K
• High efficiency, low pressure drop
• Cleaning during operation possible
• Simplicity of control, no seals
• Low tendency to fouling
• All refrigerants, glycoles, brines possible

Why a Water Chiller?

Furthermore water near freezing point at 0.5°Cis an important part in food refrigeration, to ensure the fastest possible cooling of the product due to the best possible product quality. The open, non-pressurized water side of this Falling Film Chiller or baudelot ice water cooler allows inspections and cleaning of dirt without disassembly in a few minutes. There are no additional costs for planning, piping, mounting of the valves and eletric wiring, as well as setting and programming of controllers, like known with Plate-Heat-Exchangers. No gaskets.

Most noteworthy Ice water at 0.5°C can cool large produce in very short period of time. Similarly blanching, cooling and washing processes are mainly focussed as well as mixing processes with any requirement of low temperatures while or right after mixing processes. There are various detailed sanitary adjustments for the standard Falling Film Chiller due to different process requirements in use. But the appropriate adaptation can be just as good, as the information, given by the customer, concerning the application on site.

Industrial Applications for Industrial Water Chillers

What’s the Process?

In the Falling Film Chiller or baudelot industrial water chiller the homogeneous falling film allows to chill water down to 0,5 °C. Within industrial processes it can function as pre-chiller for industrial ice bank systems or is connected to the ice water side of a Plate Heat Exchanger. Or will be pumped directly to various food cooling processes. From the water collecting tank under the Falling Film Chiller pumps to bring the chilled water to the desired consumption locations.

What are Industrial Water Chillers?

• Industrial water chiller for capacities from 10 kW to 10,000 kW
• Evaporator for all primary refrigerants (NH3, freons like R449A,R448A,R407C,R407F,R410A or CO2) and operating modes. As well as secondary refrigerants (Any type of Glycol) or for brine operation
• All stainless steel materials, from AISI304 up to titanium, 254-SMO, Duplex etc.
  This stainless steel execution gives assurance that the chilled water is always and only in contact with stainless steeel parts and can be used directly for the use required
• Plug-in units up to 100 kW, or for on-site refrigeration systems
