Dehumidifier tests

We offer comprehensive testing of dehumidifiers. Our services include tests of condensation efficiency, energy consumption, dehumidifier characteristics, abnormal operation and electrical safety tests. We also conduct comparison and optimization studies.

About our dehumidifier testing

We cooperate with domestic manufacturers of dehumidifiers, participating for many years, among other things, in the research and development work carried out by these companies on the equipment in question

A typical dehumidifier consists of the following components:

  • An inlet air filter that traps particulates that contaminate the dehumidified air;
  • An air cooler, designed to reduce the temperature of incoming moist air to a temperature that allows much of the moisture to condense;
  • A condenser, which heats the cooled air stream from the evaporator, approximately back to the initial temperature;
  • A suction fan, which ensures a constant flow of air from the environment into the dehumidifier and, after passing through the aforementioned components, pushes the air through the perforated front wall of the dehumidifier back into the environment.
  • A portion of the air stream is used to cool the compressor compartment and the electrical unit of the dehumidifier before exiting;
  • A compressor, which is the core component of the closed refrigeration cycle. Its task is to maintain the proper pressure levels in the evaporator (low-pressure side) and the condenser (high-pressure side) and ensure the required flow rate of the refrigerant in the cycle;
  • An expansion element, usually a capillary tube, which provides the expansion of the high-pressure liquid refrigerant flowing from the condenser to the evaporation pressure in the air cooler.

Additionally, the refrigeration cycle is equipped with a filter-drier, whose task is to remove contaminants and moisture from the liquid refrigerant that appear during operation.


Quality accreditation - a guarantee of trust
