Evaluating the Stability of Tunnel Washer Systems: Gas-heated Tumble Dryers

The types of tumble dryers in tunnel washer systems contain not only steam-heated tumble dryers but also gas-heated tumble dryers. This kind of tumble dryer has higher energy efficiency and uses clean energy.

Gas-heated tumble dryers have the same inner drum and transmission method as steam-heated tumble dryers. Their main differences are the heating system, safety design, and drying control system. When evaluating a tumble dryer, people should pay attention to these aspects.

Quality of the Burner

The quality of the burner?is not only related to the efficiency of heating but is also closely related to its safety when used. Direct-fired equipment must have a precise combustion control system to ensure the proportion of gas and air is proper so that the gas can be combusted completely and stably, avoiding the production of harmful gases like carbon monoxide due to incomplete combustion.

CLM's direct-fired tumble dryer is equipped with a high-power burner from the Italian brand RIELLO . It can lead to complete combustion, and it has a safety device that can immediately cut off the gas supply if the gas leaks. Using this burner, it only takes 3 minutes to heat the air to 220 degrees Celsius.

Safety Design

Gas-heated tumble dryers need individual safety designs. These tumble dryers require the design of no open flames because there is a lot of lint in the laundry factory. The open flames tend to lead to fires when facing the lint.

CLM has a combustion protection chamber that uses flameless direct-fired technology, with three electronic temperature sensors and one thermal expansion temperature sensor. The system uses a PID regulator to control the burner's flame size. If the temperature at the air inlet, outlet, or combustion chamber is too high, the spray device will automatically start to prevent accidents.

Drying Control

The reason why direct-fired equipment tends to make the linen?stiff and yellow is that the linen is over-dried because of a lack of control. Therefore, it's a necessity to choose direct-fired equipment with moisture control.

CLM's direct-fired equipment is equipped with a moisture controller, which controls the drying process in terms of moisture, temperature, and time, making the towels after being dried by gas-heated tumble dryers as soft as those dried in steam-heated tumble dryers.

These are the key considerations when selecting a direct-fired tumble dryer.
