Glycol Chiller & Heater Solutions for the Wine-Making Industry

One of the most important factors in making wine is fermentation. The rate of fermentation can impact the flavors of the resulting wine. This rate can be manipulated by controlling the temperature during the fermentation process to achieve the desired flavor characteristics.

The way winemakers do this is with the use of a glycol chiller or a chiller/heater. Glycol can be chilled below 0°C (32°F). This makes it very effective for cooling, but you will need to maintain and control a temperature higher than freezing by adjusting the flow rate of the glycol through the heat exchanger.

The range of temperatures and the duration and timing of cooling or heating are factors needing close attention to maintain flavor profiles consistently. For example, red wine can require heat early in fermentation. Typical temps are 80-90° F, and more heat can speed up the fermentation. Some prefer slightly lower temperatures with red wines to extend the fermentation or to give the wines a more fruity flavor. White wine’s fermentation temperatures are much cooler, usually over 10°C (50°F), and even more so with aromatic white wines.

Conserving Power and CO2 Emissions with Premium Efficiency Motors

The process of converting electrical energy to mechanical energy is never perfect. As much as we would like to have a 100% efficient motor, it is impossible to build a machine that will take 746 watts of electricity (the equivalent of 1 Hp) and convert it to 1 Hp of mechanical output. It always takes somewhat more than 746 watts to yield 1 Hp’s worth of output.

Motors are continuously being pushed to be more efficient and reduce these losses. Over the years the guiding regulations of motor manufacturing have pushed us to improve efficiencies to new levels to reduce the considerable global power consumption of motors, as they are everywhere. From our factories, utilities and homes and most anywhere you can think of.

How much power consumption aka money are you spending that you do not have to? Take a minute while having your coffee to see if you can save money.
