Freeze Point Suppression Cycle

What is FPS?

FPS is referring to Freeze Point Suppression. This cycle operates by changing the chemical composition of a refrigerant. In the case of IcePoint®, water is used as a refrigerant moving through four processes:

1. Freezing

Pure water is frozen into ice at the most economical time of the day and stored in a tank.

2. Mixing

A freeze suppressant, in the form of a non-chloride salt, is then injected into the bottom of the tank, mixing with the ice, which creates a -25°F refrigerant.

3. Melting

This refrigerant mixture is then used to maintain freezer temperatures by absorbing the heat and humidity from the freezer space.

4. Separation

Water is then separated from the freeze point suppressant generating pure water ready for freezing and concentrated FPS ready to send back to the ice tank.

Mechanical Vapor Recompression

What is MVR?

MVR refers to Mechanical Vapor Recompression. MVR  is the most common way to separate water from high concentration solutions.

How MVR Operates

MVR is a thermal separation technology optimized for energy efficiency. Like all distillation processes, water is boiled out of the salt-water brine. To increase the energy efficiency, the heat is recaptured and repurposed to help boil additional water.

IcePoint® Application

IcePoint® uses a standard MVR architecture refreshed with state of the art compression technology.

Energy Balance

Efficient Energy Use

Like all refrigeration equipment, IcePoint® must conserve energy and meet fundamental efficiency limits. All refrigeration equipment requires some form of driving energy input to move heat from a low temperature to a high one. For IcePoint® this comes from both the ice maker’s compressor and the MVR’s compressor. The efficiency of the IcePoint® system stems from its ability to be internally thermally recuperated and to take advantage of low ambient temperatures in the morning. evening. and night.

Add Flexible Freezing Capacity.

Increase Productivity and Throughput.

Boost Profits.

Manage Thermal Fluctuations

Maintain production line speed and blast cycle times regardless of product, packaging, or pallet characteristics.

Avoid Defrost

Eliminate evaporator frost-up by controlling moisture levels in freezers. Extract warm, moist air and re-inject it very cold and very dry.

Promote Quality, and Safety

Food Quality

Ensure proper temperatures and freeze times, even as product characteristics or facility operations change.

Food Safety

Accelerated freezing mitigates the potential for pathogen growth and contamination.

Employee Safety

IcePoint’s inherent dehumidification dramatically reduces ice buildup on floors, doors and equipment.

Operate with Ease

Supplemental Retrofit

Supercharge existing vapor compression capacity with no critical ammonia system tie-in.

Quick and Easy Install

No down time required and equipment can be placed outside your facility with simple ductwork integration

USDA Compliant

Maintain compliance via standard clean in place systems.
