- Evaporators meet the requirements for: internal cleanliness, tightness and humidity. They also have adequate corrosion resistance.
- The tubes used for production meet the requirements of DIN 8964.
- Individual components are connected by brazing.
- The tightness of each evaporator is checked for 1 minute in a water bath at 1.6 MPa overpressure.
- Each evaporator after galvanizing is blown with dry air to obtain the internal humidity required for this type of product.
