CSD(X) Series

The CSD(X) Series pushes the boundaries of compressed air efficiency by maximising the production of compressed air for less energy. These further optimised CSD(X) compressors are extremely versatile and suitable for many applications. They make the perfect air compressed solution for AEP customers looking for easy maintenance and usage, efficiency, and environmentally friendly design.

Key benefits of the CSD(X) Series include:

  • Excellent savings  - Energy is saved in multiple ways by the further optimised CSD(X) systems: the compressor airends are fitted with the newly refined SIGMA PROFILE rotors and are controlled and regulated via the industrial-PC-based SIGMA CONTROL 2 compressor controller. This innovative controller ensures compressed air delivery matches the exact requirement, so time and energy wastage is kept to the absolute minimum. 
  • Industrial applications  - CSD(X) series rotary compressors are the perfect match for high-efficiency industrial compressed air stations. The internal SIGMA CONTROL 2 compressor controller is equipped with multiple communication channels, which establishes a consistent and reliable connection with advanced master controllers, such as KAESER’s SIGMA AIR MANAGER, and in-house centralised control systems. This connection makes the setup simple and attains exceptional levels of efficiency.
  • Outstanding motor  - The new synchronous reluctance motor, which powers the CSD(X) series, is extremely advantageous. The motor contains no aluminium, copper, or expensive rare earth magnets, which makes the drive sturdy and service-friendly. Additionally, motor heat losses are kept to a minimum which results in substantially lower bearing temperatures. This guarantees a significantly extended bearing and motor service life. 
  • Electronic Thermo Management (ETM) - The Electronic Thermo Management system consists of a sensor-controlled temperature control valve integrated into the cooling circuit and is powered by an electric motor. The new SIGMA CONTROL 2 compressor controller tracks intake and compressor temperature as a means to restrict condensate formation, even with varying humidity conditions. Furthermore, the ETM system actively keeps fluid temperatures as low as possible to maximise energy efficiency. This system also allows end-users to adjust their heat recovery systems to suit their specific application.

CSD & CSDX Series - System Specifications ...

CSD & CSDX Series - Uncompromising efficiency

Save energy

At the heart of every CSD(X) system lies a premium quality airend featuring KAESER’s SIGMA PROFILE rotors. Flow-optimised for impressive performance, these advanced rotors help KAESER CSD(X) systems set the highest standards for efficiency.

Optimum efficiency

The internal SIGMA CONTROL 2 controller ensures efficient compressor system control and monitoring, whilst display and RFID reader provide clear communication and maximum security. Variable interfaces enable the networking capability.

Tomorrow’s technology, today

KAESER is currently the only compressed air systems provider to equip its compressors with super-premium efficiency IE4 class motors as standard, thereby delivering maximum performance and energy efficiency.

Required temperature assured

According to operating conditions, the innovative Electronic Thermo Management (ETM) system dynamically controls fluid temperature to ensure safe prevention of condensation accumulation and also boosts energy efficiency.


CSD T & CSDX T Series - Premium compressed air quality with add-on refrigeration dryer

Energy-saving control

The integrated refrigeration dryer in CSD(X)-T units provides high-efficiency performance thanks to its energy-saving control. The dryer is active only when compressed air actually needs to be dried: this achieves compressed air quality with maximum efficiency.

Dual cooling

Two independent fans and a separate enclosure assure high thermal reserve for the integrated refrigeration dryer. This allows the required compressed air quality to be reliably maintained at all times even at high ambient temperatures.

KAESER centrifugal separator

A KAESER centrifugal separator fitted with an electronic ECO-DRAIN condensate drain installed upstream from the refrigeration dryer ensures that condensate is reliably pre-separated and drained, even when ambient temperatures and humidity are high.

Future-proof refrigerant

The new EU 517/2014 F-gases regulation is intended to minimise emissions of greenhouse gases. KAESER’s new T-systems are equipped with R-513A refrigerant, which has a low Global Warming Potential value. Therefore, these dryers will be future-proof for their life cycle.


CSD (T) SFC & CSDX (T) SFC Series - Speed-controlled compressor with
synchronous reluctance motor

Precision pressure control

The flow rate can be adjusted within the control range according to pressure. Operating pressure is kept constant to within ±0.1 bar. This allows maximum pressure to be reduced, thereby saving both energy and money.

Durable and service-friendly

The rotors of the synchronous reluctance motor do not contain aluminium, copper, or rare earth magnetic materials, making the bearings and rotors easy to replace. Heat loss is kept to a minimum, resulting in lower bearing temperatures and extended motor service life.

Separate SFC control cabinet

The SFC variable speed drive is housed in its own control cabinet to shield it from heat from the compressor. A separate fan keeps operating temperatures in the optimum range to ensure maximum performance and service life.


It goes without saying that the SFC control cabinet and SIGMA CONTROL 2 are tested and certified both as individual components and as a system to EMC directive EN55011 for Class A1 industrial power supplies.
