ONE-STAGE

DCT 37÷315 KW

DCT - VSD

The DCT and DCT - VSD series lubricated screw compressors are particularly indicated for generating industrial use compressed air.
In case of continuous and constant air demand the compressed air needs are perfectly satisfied with DCT Fix Speed. In case of non-continuous needs and several daily fluctuations of air demand DCT – VSD is the most suitable solution.

BENEFITS OF SPEED CONTROL

The high precision detection of the working pressure and the motor speed control guarantee the perfect flow rate according to the real air demand, with considerable energy savings.

Electronic Controller

The intuitive KTronic 1000 touch screen panel permits full access to the functions, parameter control and diagnostics of the unit, increasing the efficiency of the compressor.

ADVANTAGES

DCT - VSD version with Permanent Magnet Variable Speed Motor (PM) guarantees an excellent ratio of energy costs and air flow rates.

 

It is also capable of an unlimited operating pressure adjustment. The direct drive fixed speed DCT models are equipped with IE3 motors offering an additional contribution to energy saving.

SINGLE STAGE ROTARY SCREW COMPRESSOR

Low rotation speeds allow longer bearings service life. OUR AIR-END Installed on the DCT range has an optimized rotor’s profile from the fluid dynamics point of view. By optimizing the internal circuit, the pressure drops have been further reduced thus obtaining a 8% less energy consumption improving the specific power output.


The selection of low rotation speed motor (4/6 poles in the fixed speed version) and properly sized rotary screws (max 1400 rpm) ensures the bearings a long life.


The variable speed version is equipped with Permanent Magnet Motor.

INDUSTRY 4.0

REMOTE CONTROL & CONNECTIVITY ALWAYS WITH YOU!




The KTronic 1000 can be connected to a LAN allowing the compressor to be monitored and managed from a remote PC or a SMARTPHONE.




ENERGY SAVING COMPARISON BETWEEN A VSD AND A FIXED SPEED UNIT (LOAD-UNLOAD) UNIT

The VSD unit allows the compressor to be very flexible and efficient in responding to changes in air demand. The required air demand is fulfilled through the inverter that constantly adjusts the speed of the electric motor.

The real air flow and pressure values are constantly monitored through the electronic controller to guarantee the attainment of the pre-set values.

The variable speed units guarantees more flexibility, lower energy consumption and less mechanical stress compared to the load/unload (on/off) version.

The VSD unit setting can force the standby mode when the inverter has reached the lowest rotation speed.

COOLING SYSTEM

The Variable Speed Drive (VSD) range has been developed and sized to work at 100% duty cycle even in the most severe conditions, respecting the energy saving concept due to an inverter controlled fan of the oil cooler.

All the components are fully enclosed and protected from contamination. The air cooling system has been sized to work at up to 50° C ambient temperature.

Improved fluids temperature control The coolers are separate and managed individually:

Air / Air and air / Oil
DCT - VSD: The oil cooler fan is inverter controlled and is dynamically managing the temperature of the fluid. In this way, the oil temperature is controlled perfectly with relevant benefits in the oil circuit, and improving the energy savings as well. In addition, the separate air cooler management allows to optimize the air temperature at the compressors outlet thus avoiding condense formation and eliminating the damages caused by humidity. As consequence the dryer installed after the compressor will have also benefits on the lower operating load.

All these features allow energy savings for all the system.

ORIGINAL KTC SPAREPARTS

All external panels of the compressor are easily removable allowing easy access to all the components requiring routine maintenance.
