General characteristics

New polymers are constantly being developed and component manufacturing techniques appear, allowing the gradual replacement of metallic materials by plastics or composites, in various fields of application, in different industries. In particular, in the air conditioning, heating and water supply sector, plastic components are subject to the aging process due to the temperature to which they are subjected or due to the amount of oxygen in the fluids.

The  Test System for Longevity and Accelerated Aging Tests  developed by Controlar allows to foresee, in accelerated test, the wear throughout the life of the plastic components of the hydraulic systems, in order to prevent eventual failures during the useful life cycle of the DUT.

Architecture

The main module controls and analyzes the test variables. There is a hydropressor group that unifies the pressure in all modules up to 10 bar. A pneumohydraulic system injects air / oxygen into the water through a diffuser until oxygenation reaches the level predefined by the user. To monitor these oxygen levels in the water, the equipment makes periodic measurements through a high precision sensor.

Each test module has an individual heating circuit that allows testing at different temperatures up to 90 ° C. The test booths are closed and thermally insulated in order to reduce energy losses. The size and number of test modules are configurable according to customer needs.

An additional module allows to test the samples with failure and, based on the information collected, to calculate the expected useful life of the components tested according to the Arrhenius equation.

Applications

The  Test System for Longevity and Accelerated Aging Tests  is suitable for applications in the thermotechnology industry, such as for acceleration tests of aging heat pumps (air-water or hydraulic type) through the simulation of domestic consumption or geothermal; or for the characterization of the efficiency of electric water heaters.
