Ircon solaronics provides industrial solutions for the electrification of various air dryers.
Electricity can be used as a source of energy for convection dryers to replace existing dryers with gas burners or steam coils.
An electric duct heater consists of heating elements (tubes with resistance coils) placed in a casing which is connected to the ducts of the dryers.
The heater is equipped with a junction box in which the electrical connections of the heating elements are assembled.
The junction box is sealed to prevent heat transfer into the housing.
Electric resistance packages can be installed in place of or alongside existing gas heaters as a hybrid solution, allowing the choice of heat source according to the cost of energy.
We have implemented both solutions in Finland.
The power can be adjusted from 0 to 100% infinitely variable.
The third option is a steam radiator, where we can compensate for any reduced drying capacity with electrical inputs.
We also provide turnkey solutions including mechanical-, piping-, electrical-, automation installations, as well as software programming for different operating systems if required.
Replacing the gas burner with an electric duct heater usually leads to an improvement in the overall efficiency of the whole system => the energy used for evaporation (kWh/kgH2O) is reduced after electrification.
The reasons for this improvement are the following:
- The gas burner needs combustion air for the combustion reaction, which has to be heated to the target temperature of the process air.
- In gas combustion, one of the by-products is water. This water from combustion increases the humidity of the process air, which has a negative effect on the evaporation efficiency of the drying system.
