4. PRODUCT INFORMATION

4.1. Purpose and use

Oil-free compressor DK50 4x2V/M - DUPLEX with dryer MONZUN serves as the source of dry, clean, oil-free compressed air for driving pneumatic appliances and equipment. With its performance, operational pressures, but also economic operation, it is suitable for the use in large dental laboratories, dental clinics, with another auxiliary device even as the source of compressed air for driving devices for support of respiration, for departments of hospitals, as well as in further areas of medical practice, in food industry, and everywhere clean and dry compressed air is necessary and where compressor with its version, performance and operational pressure meets the given requirements.

The device is construed for environment of interior spaces, where temperature of air is within the scope of +5°C to +35°C, relative humidity does not exceed 80% and absolute humidity of air does not exceed 15 g/m

Oil-free compressor DK 50 4x2V - DUPLEX (without dryer) serves as the source of oil-free compressed air for driving pneumatic appliances and equipment.

4.2. Product description

The assembly consists of four oil-free, piston, two-cylinder compressors driven by three-phase electric motors located on two air chambers with fittings for input of compressed air, check valves, pressure meter, safety valves, pressure switch and sludge valves. Air chambers are mechanically connected via stabilizing consoles and at both rounded sides of air chambers are connected by direct pipes. The output of compressed air from entire unit is created by ball valve with internal G3/4“ thread.

Valid for DK50 4x2V/M

There is mechanically fixed air dryer MONZUN with cooling unit. New type of the safety valve (PRV) is included into the pneumatic distribution between the compressor aggregates and the dryer. The safety valve for the air (PRV) is intended for the prevention of pressure increase in the pressure circuit of the compressor over the permissible value, providing for the protection of individual pneumatic parts, above all for the compressor aggregates against an adverse influence of inadequate pressures. The opening pressure of PRV is set to 11 bar.

It is forbidden to deliberately reset the opening pressure on the safety valve; the resetting should always be agreed on with the manufacturer!

The outlets on the safety valve may neither be closed, nor the pressure air exit therethrough limited.

When the pressure in the pressure circuit of the compressor increases to the value of set opening pressure, the PRV automatically starts letting the air from the system through. When the pressure drops, the PRV will close.

The pressure increase in the pressure circuit can only occur due to the increase of flow resistances of the pneumatic distributions or in case of the dryer failure (e.g. non-functional solenoid valves, increased flow resistance of a drying material and similar) and therefore if a repeated opening of the safety valve occurs, it is unavoidable to check the dryer function, possibly to repair it

7. PUTTING THE PRODUCT INTO OPERATION

After assembly and connection of the device to electric mains of 3 x 400V+N+PE, put both circuit breakers FA5 and FA6 to I position. Then switch on switch of pressure switch SP, when all four compressors shall be put into operation, two immediately (M1, M2) and two (M3,M4) after time delay of 1-2 s. (adjusted at KT1). AS main switch, you may still use switch of pressure switch SP. After the first connection of compressor to mains voltage, the pressure in common air chamber shall be increased up to the value of switching off pressure SP (8 bar), when compressors shall be automatically switched off. In further cycles, the compressors work in automatic mode, i.e. according to the consumption of compressed air the compressors are switched on (at 0.6 MPa) and switched off by pressure switch SP. After prolonged operation of compressors or when temperature is increased at surface of engines

above 40oC, thermal switches ST1 ( ST2 ) shall switch on cooling ventilators EV1 and EV2 ( EV3 and EV4 ) thus cooling of compressor aggregates shall be ensured even during their break. After

decreasing temperature in the space around engine under cca 35oC the relevant ventilators shall again switch off. ventilators EV1 and EV2 ( EV3 and EV4 ) are always switched on at the same time with engines of compressors M1 and M2 ( M3 and M4 ).

Such installed compressors do not require any attendance during operation. In next mode, the compressors work automatically.

Pressure switch located on the air chamber has beforehand adjusted pressure value. It is not allowed to change this value by readjusting of pressure switch.

The pressure presetting of safety valve is forbidden!
