What is the difference between DRY and WATER COOLER?

In a dry cooler, the beverage coil is cooled by a cooling coil. Thanks to the contact of these two coils and the specially designed thermo block in which these coils are hidden, the beverage is well-chilled within a few minutes, without the need for a long cold. Water coolers have a water container directly inside, chilled by an immersed cooling coil. As a result, an ice bank is formed, followed by cooling of the beverage coil.

What does the number in the cooler name indicate (eg Pygmy 25 / K)? 

Continuous output of the device in liters per hour.

What does the Green Line version mean in the cooler name? 

The coolers labeled Green Line are coolers with refrigerant R290 and the adapted cooling system. It is an ecological refrigerant, thanks to which our coolers achieve up to 5% higher performance than previous versions with R134a refrigerant.

What does the letter “K” in the cooler name indicate? 

The letter "/ K" indicates the built-in air compressor for pressurization.

Why is the name “Kprofi” sometimes in the cooler´s name?

The dispensing machines marked "/ Kprofi" have a built-in air compressor with the possibility of regulating the compressor pressure. For some "livelier" beers, mostly specialties from mini-breweries, it is necessary to reduce or increase the pressure on the compressor. The beer then flows better and does not foam.

What else do I need for a Contact dispensing machine? 

You always need an air tube (outer diameter 8 mm) and a beverage tube (outer diameter 9.5 mm) for the dispensing machine. Then the correct dispense head for the keg- S, A, M-type or other, fittings for the coupler F5 / 8x8 mm for air and F5 / 8x9.5 mm for beer lines. Last, but not least, a sanitation adapter for basic water cleaning.

Why is it good to have a dispensing machine with a built-in air compressor? And what should I do if I don't have it in my device?

The built-in air compressor simplifies the use of the device and its operation. It allows the device to be easily transferred without the need to have an external air compressor or cylinder ready for the device. If you have a device without a built-in air compressor, we offer the option of additional installation in contact devices. Contact us for more information.

The Contact dispensing machines (dry coolers) - cooling of beverages

What should I check if the device does not want to turn on?

First of all, check that the machine is connected to the mains, then check that the machine is switched on (the appliance is switched on by turning the thermostat clockwise). 

What should I do if the drink is warm?

Use the thermostat knob on the front to lower the temperature (by turning the thermostat clockwise)

How long does it take for the drink to cool in the cooler?

The cooling time for contact coolers is approximately 10 minutes. 

What happens if no beverage flows out of the machine after switching off the cooling circuit?

Your machine may have frozen. This happens when you switch on the cooler immediately without dispensing the first beer after you flushed the lines with water. The water left inside after the previous flushing will freeze. Place the machine in a warm room for a few hours, it should thaw and continue to function properly. If this does not happen, contact our service department.

The Contact dispensing machines (dry coolers) – pressurization

Why should I buy a device with an integrated air compressor?

The built-in air compressor simplifies the use of the cooler and its operation. It allows the machine to be easily handled without having to have an external air compressor or a gas cylindr.

What should I check if the integrated compressor has not started to pressurize?

Check that the machine is connected to the mains and that the compressor switch is in the “I” position (the switch is located on the back of the refrigeration unit). 

What controls the switching of the integrated air compressor and to what value is the pressurization set? 

The switching of the air compressor is controlled by an automatic pressure switch, which is set to a switch-off value of 3.2 bar and the value of switching on the compressor is 2.8 bar.

What should I do if the air compressor pressurizes but does not want to switch off?

Check all tube connections for air leaks from the line. You can also try cutting the ends of the tubes flat. Occasionally, after a long period of use, the ends of the hoses wear out and then do not seal properly in the quick plastic fitting. The compressor therefore runs continuously as it does not reach the required pressure. 

I have cooling with an integrated air compressor, but I would like to use another source for pressurization, is it possible? 

Yes, the use of a built-in air compressor in the machine is not a requirement. You can turn it off using a separate switch on the back of the cooler. You can then connect any external pressure source.

What can I check if the beverage foams excessively? 

Make sure the beverage is not hot. If so, lower the desired temperature. If you use an external pressure source, you can increase the outlet pressure.

How do I clean my machine? 

Using the sanitation adapter, you can do a basic rinse with water (we recommend rinsing after each keg is dispensed). With the help of the sanitizing set, you can easily sanitize the machine even in domestic conditions.

Beer flows around my hose to connect to the cooling device. How do I remove it? 

Cut about 1 to 2 cm of plastic tube.

Is it possible to replace a classic tap with a lever one?

Yes, it is possible to replace the tap with another type. To change the tap, it is necessary to replace the fittings built into the machine. We recommend using the professional services.

Water coolers - general questions

How should I choose the dispensing equipment? 

Several factors need to be monitored. Power (output), given in liters per hour (l / h), the number of coils (beverage circuits), frequency of use (daily, only weekend, season, etc.) and location (under the bar, in the cellar, on the bar), or according to number of seats (restaurant, garden). 

What is the difference between a WATER and DRY cooler?

The dry cooler is easier to operate, does not need to be filled with water and has a faster onset of cooling after switching on. Conversely, water cooler can use chilled water to cool the beverage line. Does not contain an air compressor.

On what principle does the WATER COOLER work? And what is the difference between the AS and CWP series?

The cooling circuit for water cooling cools the water inside the tank through which the beverage coil passes where the beverage is cooled to the desired temperature using ice water. In the case of water cooling type machine AS, the coils of the cooling circuit and the beverage circuit are not in contact, the cold is transmitted by ice water. With water cooling type CWP, the cooling and beverage loops are in direct contact, the cooling is more efficient and has a faster start-up after switching on (suitable for establishments where it is not open daily).

What is the difference between an under counter and a table top cooler? 

The water table top machine has taps located directly on the machine. The water under counter machine does not have the taps and it is necessary to connect it with the dispense tower (tap). 

What does the Green Line range of coolers mean?

The Green Line model is a series of ecological coolers where R290 refrigerant is used. These coolers have 20% higher efficiency and 20% lower energy consumption. 

What does the number in the description of cooler indicates (for example AS-80 Green Line)?

The number in the name ranks cooling output, ie according to how many liters of chilled beverage the machine can prepare in 1 hour under ideal conditions (AS-80 = max. 80l / h).

What do I need to start using the dispensing equipment?

Pressurization (oil-free air compressor or pressure bottle with food gas CO2 / mixed gas + pressure reducer), dispense head, beverage line (tube / python), dispense tower, drip tray and JG fitings for connection.

Water coolers - cooling the beverage

What can I check if the cooler does not want to turn on? 

Try checking the power cord connection and the functionality of the outlet. Furthermore, the connection of the cable from the stirrer to the cooling, the position of the main switch and the position of the thermostat in the "0" position. 

What should I do if the beverage is warm?

Add to the cooling intensity by turning the thermostat knob clockwise. If this does not help, remove the upper lid of the cooler and check that the beverage coils are not frozen and that the impeller is rotating from the stirrer (ice must only be on the perimeter of the water tank).

How long does it take for the beverage to cool in the cooler?

With the water cooling of the AS series, the beverage is cooled from switching on in approx. 90 minutes and with the CWP series in approx. 15 minutes.

Cooling is iced, but is the beverage still warm?

The water circulation in the tank probably doesn't work. Check the function of the stirrer and its connection.

What happens if no beverage flows out of the machine after switching off the cooling circuit?

The drink coil probably froze. Switch off the cooling, disconnect the beverage line and allow the cooling to melt. We also recommend checking the pressure source to make sure it is working.

What should I do if the device is too noisy?

Check that no object has entered the fan impeller. If necessary, check the agitator for something covered or clogged.

Water coolers – pressurization

What can I pressurize with?

Either with air - durability approx. 2-3 days, with oil-free air compressor. Or a technical gas - durability about 1-2 weeks. The most commonly used is a cylinder with a pressure reducer with food gas CO2 or mixed gas. A pressure control panel can be used to set different beer / beverage pressures.

Water coolers - dispensing

What should I check if the drink foams excessively?

Check that the required beverage has cooled down sufficiently, or add to the cooling intensity. Also check that no bubbles rise from the keg in the beer tube, in which case the pressure needs to be increased. The last aspect that can affect excessive foaming is the cleanliness of the entire line.

How do I clean my cooler?

Rinse the cooler with water using a sanitation adapter, which you connect to the water supply system. This is possible even without connection to the water supply system using a sanitizing keg for a chemical sanitation. You can also leave sanitation to professionals.

What should I do if my beer flows around the tube connected by the plastic fitting?

Disconnect the tube from the speed plastic fitting, cut approx. 2 cm and reconnect. If the condition does not improve, it is necessary to replace the speed plastic fitting.

There is no beverage flowing from the machine, what should I do?

Gradually check the connection of the tubes, the position of the dispense head lever (downward position), whether there is no sanitary ball left in the beverage line after sanitation, whether there is a non-returned valve turned flat down inside the dispense head or whether the cage above the sanitary ball is missing. Also check that the beverage line has not frozen.

How far can the kegs be from the dispensing equipment?

Horizontally, even tens of meters, but only 7 m high.
