What are the recommended fans for refrigeration and freezing equipment?

In refrigeration and freezing equipment, maintaining a stable low-temperature environment is essential to maintain the quality of food, medicines, and other products.
For this reason, the cooling fans that cool the heat-generating parts and circulate the air inside the cabinet must be highly reliable and have excellent environmental resistance.

This article explains specific usage scenarios in stores, the characteristics required of cooling fans for refrigeration and freezing equipment, and the types of fans actually used.

1. Fans installed in store refrigeration and freezing equipment

Let's take a look at where fans are installed in the refrigeration and freezing equipment used in stores.

2. Fan characteristics required for refrigeration and freezing equipment

Quietness

Refrigerated and refrigerated display cases and wine cellars used in stores are used in environments where people are nearby, so the noise of their fans can be a nuisance.
Selecting a fan with excellent noise reduction will help create a comfortable space.

Waterproof

In refrigeration and freezing equipment, fans are often exposed to moisture due to water droplets or thawing of frost.
The use of Splash Proof Fan that can be used safely even in wet environments ensures stable operation and reduces the risk of breakdowns.

Driven by AC input

Although there is a strong demand for AC-powered fans in refrigeration and freezing equipment, there is also a strong need to take advantage of the low power consumption and long life of DC Cooling Fan.

DC Cooling Fan consume less power than AC Cooling Fan, which improves the energy efficiency of the entire equipment. In addition, they have a longer life than AC Cooling Fan, which reduces the amount of maintenance work required. ACDC Fan are driven by a DC motor via a built-in small AC-DC conversion circuit, so they exhibit the excellent features of DC Cooling Fan such as low power consumption and long life.
