ENVIRONMENT TEST 2

HUMIDITY CHAMBER - Model 6850

The purpose of this test is to create a high humidity environment for testing of electrical appliances and components.

Technical Data:

• Internal measures of humidity chamber can be tailor-made according to the requirements of the customer.  A standard dimension of the chamber is 2000W x 3000D x 2000H (mm).

• Walls are made of steel and has a 100mm insulation material.  Door is 800W x 200H (mm) with inspection window.  The walls are built up of modules 600W (mm).

• The humidity air is injected form a special perforate ceiling.

• The standard test chamber is designed for steady state operation - it means that the testing parameters are fixed during the testing.  We can also offer chambers with cycling parameters.  When testing, according to IEC electrical safety standards such like IEC 335, IEC 598, etc.; common used parameters are: Constant temperature 29° C and R. H. (relative humidity) 90% +/- 3%.

• Parameter values for temperature and relative humidity can be set to other fix testing values around up-mentioned parameters - still for steady state operation.

• The principle of creating the humidity is to transfer water into steam phase.

• Cooling system through air condenser.

• control unit with compressor is stored in an appliance box with recorder and all other operation switches and indication lamps.

• IEC Reference: All standards.

• Supply: 3 x 380V, 50Hz, compressed air 8-bar.

• Dimensions: Depending on ordered chamber.

• Weight: Approx. 400 kg.

DUST PROOF TEST CHAMBER

The purpose of the Dust Proof Test is to create a flow air through an enclosure at least 80 times of the volume of the sample with a flow speed not exceeding 60 volumes/hour.

The vacuum pressure must not be lower than 200 mm column of water.

Technical Data:

• The size of the chamber can be tailor-made according to the customers wishes of dimensions.  The chamber is built-up of wood (block wood).  The wall elements are fixed together with screw bonds.  During the transportation of the chamber the volume of the chamber will be decreased.  The size of a standard chamber is: H200 x W1200 x L1900 mm.

• The door has the size H1800 x W70 mm with an inspection window.

• Vacuum pump, flow meter and mechanical regulation valve are included.

• A frame work of aluminum profiles inside the chamber to put the sample on is included.

• Two powerful fans circulate the dust (talk powder) around the chamber.  The fans are operating ON/OFF with a timer.

• Vibration devices to avoid dust collection on the walls are operating ON/OFF with certain intervals.

• Vacuum pump, flow meter, vacuum pressure gauge and regulation valves are included.

• IEC reference: All

• Supply: compressed air 6-bar and 3 x 380V 50Hz, 3kW

• Weight: Approx. 150 kg
