Freeze resistant water fountains

All our drinking water fountains for public areas are weather-resistant, vandal-proof and “frost-resistant”. This means that they do not freeze in winter as long as they are winter-proof. This includes ensuring that the water from the pipes drains as well as possible so that the water pipes do not burst in the event of frost. As an alternative, there are special systems with which an outdoor drinking fountain can remain connected to the fresh water pipe even in winter and dispense water even at sub-zero temperatures. Our frost-resistant drinking fountains are therefore winter-proof from the outset without further action as well as weather-resistant and vandal-proof. Three cheers for stability!

The frost-resistant water dispensers are characterized by their additional construction below the ground frost line. A burst of water pipes is due to frost due to a return valve excluded. The disadvantage: After pressing the water-jet push button, a frost-resistant drinking fountain takes a few seconds longer for the water to bubble, as it must first flow through the additional valve built into the floor before it reaches the bottle filler or the drinking faucet.

How does a winterproof water dispenser work?

There are two types of frost protection systems for outdoor drinking fountains to allow use in winter when temperatures drop below freezing: frost-proof and sealed (or sanitary) frost-proof models. While the models use different valves, both models are installed below the frost line and extend the period of time they can be used all year round, while eliminating the need for deactivation in winter.

In a frost-proof model, the valve of the piped drinking fountain is designed to be installed in the ground below the frost line. This is usually between 127 mm and 1,829 mm underground. When the device is activated, the vent line pushes into the valve, which then opens and pushes the water that is below the frost line upwards through the device.

The sealed (or sanitary) frost-proof models have the same features as the frost-resistant models with the added advantage that the valve is in a sealed canister. This sealed container minimizes groundwater contamination and prevents runoff water from mixing with fresh water when the drinking water fountain is installed in areas where groundwater levels may rise due to inadequate drainage, or in areas where flooding may occur.

Drinking water fountains set up in public places in particular often cannot be checked daily and shut down immediately when frost sets in. The additional investment may be worthwhile here. Below is a selection of wired water dispensers that are protected against damage caused by frost.
