Solution Overview
Problem
Compressed gas lines are susceptible to ambient temperature and pressure fluctuations, leading to condensation and drop formation, which is problematic in explosion-protected areas and affects the quality of the gas for applications like spraying.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If compressed gas is humidified in the compressed gas line, then spraying quality is improved, but condensation and drop formation occur due to temperature fluctuations
Solution Approach 1:
The patent applies preliminary action by heating the compressed gas line before humidification occurs. The heating device pre-warms the line to a temperature above the dew point, ensuring that when humidified gas is introduced, condensation does not form. This preventive heating before the harmful effect can occur resolves the contradiction between achieving high spraying quality through humidification and avoiding condensation issues.
2Temperature
If electrical heating spirals are used to prevent condensation, then temperature control is improved, but explosion protection is compromised in Ex-protection areas
Solution Approach 1:
The patent replaces the electrical heating system with a hydraulic heating system. Instead of using electrical heating spirals that pose explosion risks in Ex-protection areas, the invention uses a heating device that circulates heated liquid through the compressed gas line. This mechanical/hydraulic substitution maintains effective temperature control while eliminating the explosion hazard associated with electrical components in hazardous atmospheres.
3Object-affected harmful factors
If a liquid-based hose heater is implemented, then condensation risk is reduced, but device complexity increases
Solution Approach 1:
The patent merges the heating function with the existing compressed gas delivery system by integrating the heating device and fluid line into the same infrastructure. The heating device connects to the compressed gas line through integrated connection elements, allowing the heating system to be implemented without requiring completely separate, complex infrastructure. This merging approach reduces overall system complexity while still providing effective condensation prevention.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The system effectively prevents condensation and droplet formation, maintaining high gas quality and ensuring adequate explosion protection, leading to better spraying outcomes such as improved coating or painting results.
Implementation Method 1
the compressed gas treatment system has a heating device for heating a liquid (heat carrier)
Implementation Method 2
A liquid-based hose heater is thus created. The risk of condensation and the formation of drops in the compressed gas line is thus significantly reduced.
Implementation Method 3
it is desirable that condensation and the formation of drops from humidified compressed gas can be avoided
