Outstanding features

The accurate design, the manufacturing through a large number of line with many working centres at numerical control and the accurate quality tests, grant the performances excellence of compressors R-TS.

• Exclusive design of screw profiles with a ratio 5:6 between male screw and female screw
• Electrical motor with very high efficiency
• flowing through slots of the rotor, suction gas is centrifugated for liquid separation
• Optimized Vi built-in volume ration
• calibrated lubrication of the screws
• Sturdy and simple design of mechanical parts carefully manufactured
• Roller bearings largely sized
• Simple and efficient capacity control device
• High efficiency electric motor with part-winding start
• Low noise level and smooth vibrationless running
• Excellent volume capacity ratio
• Lightweight

Construction features

• Two shaft rotary displacement design, with innovative profiles of the screws
• The two screws (male screw and female screw) are manufactured by means grinding and Assembled with precision into the screw housing
• the shafts are fitted with roller bearings sized to bear both radial loads and axial loads also when compressor stops and a reverse turning takes place
• Cooling of electric motor is carried out by the suction gas flowing through slots of the rotor

Standard equipment

• discharge connection complete with valve and check valve
• Suction valve
• Capacity control device
• Electronic protection device
• Electric box with IP65 protection
• Oil piping kit (see page 24)

Capacity control

• Variable volume ratio system with simple design
• Parts in motion of the device free of alignment problems

Electronic protection device

• Control of the maximum winding temperature through six thermistors type PTC
• Control of the maximum discharge temperature through a thermistor type PTC
• Control of the direction of rotation of electric motor
• Phase and voltage failure protection
• Manual or automatic reset; automatic reset with 5 minute delay on compressor starting to avoid a frequent sequence of compressor starts and stops.
