Mueller Falling Film Chillers Are Designed to Cool
Any Fluid to Within 2°F of its Freeze Point
The primary application for Mueller's falling film chiller is to cool food-grade liquids that will become an ingredient of a food product, or that will come into contact with a food product.
Other applications include cooling fluids that have an initial temperature of more than 80°F. This task cannot be accomplished in most conventional chillers.
Mueller chillers are available in the following models. Please select

Standard Option Concept
The falling film chiller product line was designed around the Standard Options Concept to enable us to improve quotation lead time and delivery time, and to lower cost.
This concept has allowed us to pre-design the entire product line once, therefore, eliminating the unnecessary cost of re-engineering a custom product for each order.
By taking the time to evaluate the needs of all of our different customers, we were able to design all of the needed options. This also makes it unnecessary for our customers to pay for something on their chiller they do not need. These two advantages provide you with the lowest cost and the shortest lead-time in the industry.
Cabinet Sizes
We currently build two chiller sizes, 3x5 and 4x8. The 3x5 chiller is available in an 8-plate cabinet.
The 4x8 chiller is available in an 8-plate, 16-plate, 24-plate, and 32-plate cabinet. Each of these chillers has a tank that was properly sized to satisfy the requirements for the chiller.
We also offer a tankless chiller cabinet in the following sizes: 8-plate 3x5, 8-plate 4x8, 16-plate 4x8, and 24-plate 4x8.
Cabinet Top Options
Each cabinet is available with a welded-in-place top or a top fitted with a hinged door over each distribution pan.
The above options allow for access (or not) to the top of the chiller depending upon your needs.
Cabinet Expandability
Due to the advanced cabinet design of all of our chillers, adding additional plates up to the cabinet capacity is easy to do. So when you get ready to buy your next chiller, be sure you select a cabinet that allows for future expansion. Then, when the expansion time comes, you will only have the cost of additional plates and distribution pans, not a second chiller which requires an expensive installation.
Evaporator Features and Options
We offer 3x5 and 4x8 plate sizes. Each plate size is available for DX, recirculated, and flooded refrigerant controls for R-717, R-22, R-404A, and all other conventional refrigerants.
Due to the plate design, no special refrigerant controls are necessary nor are you forced to select flooded controls when DX would be less expensive and a better fit for your application (because of the plate design).
All plates are built to ASHRAE 15 standards rated at 300 psi at 400°F. Optional ASME plates at the same rating are available.
Evaporator Internal Plate Capacity
The Mueller Temp-Plate® patented design is the most efficient falling film chiller evaporator available today. Each evaporator is designed to use the smallest refrigerant charge possible and is circuited to ensure that the entire evaporator operates at the correct temperature. The internal volume for the 3x5 plate is .15 cu. ft. and for the 4x8 plate it is .42 cu. ft. These capacities are 8 to 10 times less than others.
Tank Connection Options
Each chiller is laid out with multiple locations for tank connections. This option allows you to pick the location and any standard size connection for your chiller. You can select the connection size at each end from our list of standard connections located on the submittal drawing for each cabinet.
Refrigerant Controls
We provide DX and flooded refrigerant controls for all refrigerants. For details on the individual components, review the Falling Film Chiller Operations and Installation Manual.
Water Level Control Option
All Mueller falling film chillers are equipped with a 1/4" connection to allow for the installation of an optional water level control. This control will allow you to set the upper and lower level any where you choose.
There are three optional control panels which allow you to set the level control. The three components needed to operate the level control are the pressure transducer, a 1" water solenoid valve, and one of the optional control panels described in the Control Panel Options section.
Control Panel Options
We offer three standard control panels. The following is a brief description of each panel. - Model 100 Control Panel: The Mueller Model 100 chiller control is designed to control chiller water temperature. It requires 230/60/1 electrical input. Outputs to control temperature are 24-volt to operate a refrigeration unit, chiller circulation pump, process circulation pump, and optional water level control and fill solenoid valve.
- Model 200 Control Panel: The Mueller Model 200 chiller control is designed to control chilled water temperature. The chiller control will accommodate 208/60/3, 230/60/3, or 460/60/3 electrical input. Outputs to control temperature are 24-volt and can operate up to four stages of refrigeration. It will also control the operation of a chiller circulation pump (up to 5 hp), a process circulation pump (up to 5 hp), and optional water level control and fill solenoid valve.
- Level Control Panel: This board is mounted in the 6" x 6" level control box and can be used to set up the reservoir level to control the water fill valve.
Refrigeration Units
We offer a complete line of condensing units that have been designed to match the performance requirements of the falling film chiller.
These units are available in outdoor air cooled, water cooled, and remote air cooled (with outdoor) condensers. Each type of unit is available in sizes from 5 thru 120 hp. Some sizes may not be available in all types.
Specially Designed High Sides
Custom high sides of all sizes and configurations are available upon request.
Quotation Lead Time
For quotations on chillers with standard options, the normal lead time is 24 hours or less from the time we receive your request. Requests for quotes that include no standard options may take longer.
Order Lead Time
The normal shipment lead time, after the receipt of an order, is four weeks. Some orders with special requirements may take up to two weeks longer.
Options and Accessories
Refrigerant Controls
Refrigerant controls for ammonia and other refrigerants including direct expansion, flooded, and recirculated systems are available.
Refrigerant Circuit Manifolds
Refrigerant circuit manifolds are available to simplify installation. Manifolds for DX systems include valves and external equalizers already mounted. Flooded and recirculated manifolds are available in copper and stainless steel materials.
Additional Equipment
Surge drums, receivers, hand valves, and other refrigerant accessories are available upon request.
Pumps
Circulating pumps are available in various flow ranges and materials to suit your needs. |
