The KAESER range of compressed air dryers including Refrigerant and Desiccant dryers plus a series of Pre and After air filters, remove potentially harmful contaminants, such as water, oil, dirt, and odours.

Clean, dry, compressed air protects downstream pneumatics, tools, control gear, and ancillary pipework from corrosion and contamination. The KAESER range of innovative Refrigerant and Desiccant compressed air dryers can help achieve this reliably, cost-effectively and energy efficiently.

Drying

The atmospheric air drawn into a compressor is a mixture of gases that always contains water vapour. However, the amount of water vapour that air can carry varies is mostly dependent on temperature.

As air temperature rises – which occurs during compression – the air's capability to hold moisture increases also. When the air is cooled its capacity to hold moisture reduces, which causes the water vapour to condense. This condensate is then removed in the centrifugal separator, or the air receiver, downstream from the compressor. Even then, the air can still be completely saturated with water vapour. This is why, as the air cools further, significant amounts of condensate can accumulate in the air distribution piping and at take-off points. System failure, production downtime and costly service and repair work are therefore unavoidable without additional air drying.

Technical specifications

TAH – TCH series Flow rate: 0.35 to 4.50 m³/min

Exceptionally reliable and ultra-compact KRYOSEC refrigeration dryers typify renowned 'Made in Germany' quality. They provide dependable drying in ambient temperatures up to +50 °C and ensure high efficiency performance through their low maintenance design and the minimal pressure loss heat exchanger system. With their compact footprint they are exceptionally versatile and are ideal for locations where space is at a premium.

Lower pressure differential The dryer's stainless steel plate heat exchanger is complemented by an air-air heat exchanger. Low pressure differential and high quality insulation ensure energy-efficient operation at all times. The integrated condensate separator provides dependable performance even under conditions with fluctuating compressed air flow.

Standard-compliant design KRYOSEC dryers fulfil machine safety requirements in accordance with EN 60204-1. The high quality lockable on/off switch clearly indicates the switch position. They are also equipped as standard with an integrated power supply isolating device.

Secotec Refrigerant Air Dryer

TA to TD series

Flow rate: UP TO 8.25 M³/MIN

SECOTEC refrigeration dryers reliably remove the moisture from compressed air while minimising energy consumption. They feature premium quality components to ensure a long and dependable service life. The cycling control enables significant energy savings.

Made in Germany: All SECOTEC refrigeration dryers are built in accordance with the very highest quality standards at KAESER's plant in Gera.

Secotec Refrigerant Air Dryer

As with all KAESER products, SECOTEC dryers are designed and built for maximum reliability. The broad range of available models makes it possible to install the most suitable dryer for virtually any application.

Exceptional efficiency

The high capacity thermal mass is cooled down to cut-out temperature by the refrigeration circuit and extracts the heat from the compressed air that flows through the heat exchanger. As soon as the temperature of the thermal mass rises to the cut-in temperature the refrigerant compressor starts and cools it down again. This feature considerably reduces power consumption compared with non-cycling controllers.

Saves energy:

SECOTEC control The SECOTEC cycling control significantly reduces energy consumption compared with conventional systems with continuous control. The refrigeration circuit is activated only when cooling is actually required.

Minimal pressure drop

SECOTEC series dryers ensure minimal pressure drop thereby saving additional energy, as the required maximum pressure is reduced.

No pre-filter

SECOTEC energy-saving dryers do not require a pre-filter (with piping unaffected by corrosion). This translates into significantly lower investment and maintenance costs, as well as a lower pressure differential.

TE-TF Series

Flow Rate: 10.5 to 34 m³/min

The next generation: Even more efficient compressed air drying

SECOTEC – that's the name of KAESER's renowned industrial quality refrigeration dryers that have long been valued for their stable pressure dew point performance, their exceptional dependability and their low total life-cycle costs. Together with the innovative SECOPACK LS latent heat storage heat exchanger system and the SIGMA CONTROL SMART controller, the next generation of these advanced dryers sets new standards when it comes to energy efficiency, compact design and user-friendliness.

SECOTEC TE-TF series refrigeration dryer

Energy savings

SECOTEC TE-TF series refrigeration dryers require less than 87 W of electrical power per m³/min of compressed air (ISO 7183 A1). Thanks to the energy-saving control, reserve cooling performance can be temporarily accumulated in the thermal storage medium during partial load operation and can subsequently be used for drying purposes without the need for additional energy consumption. The rapid reaction SECOPACK LS heat exchanger system ensures stable pressure dew points at all times.

Optimised and compact

The thermal mass storage section of the innovative SECOPACK LS heat exchanger system is filled with a phase change material. Its significantly higher thermal storage density means that 98 % less storage material is required to achieve the same capacity as conventional storage media. This impressive storage capacity not only ensures excellent pressure dew point stability, but also drastically reduces space requirement. Optimised flow channels reduce pressure losses and further enhance the energy efficiency of the SECOTEC TE-TF series dryer.

Intuitive operation

The electronic SIGMA CONTROL SMART controller with colour display and language-neutral menu design is simple and intuitive to operate. Message memory, component-specific operating hours counters and maintenance timers enable efficient monitoring and analysis of operating data. Floating contacts make networking with master controllers, such as the SIGMA AIR MANAGER, quick and easy.

Long-term efficiency

The high quality cooling circuit in SECOTEC TE-TF series refrigeration dryers enables dependable performance in ambient temperatures up to +45 °C, and optionally as high as 50 °C. The generously sized condensate separator and the electronic ECO-DRAIN condensate drain ensure dependable condensate removal in all load phases. Durability is also increased through the use of stainless steel compressed air piping and because the condenser and SECOPACK LS are made from aluminium. The electrical equipment complies with standard EN 60204-1.

Low Pressure Dew Point with DC Desiccant Dryers

Series DC

Flow capacity 0.15 to 154.53 m³/min

Dependable Drying Power up to -70 °C

Meticulous design and quality ensure that KAESER DC Series desiccant dryers operate efficiently to provide dependable low-pressure dew point performance at continuous load, even under the toughest of conditions. The outstanding drying results are aided by generous quantities of KAESER’s high quality ‘SIGMA Dry’ desiccant, as only a fraction of the material’s initial load is used. Consequently, this means that minimal quantities of purge air are required for desiccant regeneration, even after longer than average periods of operation. In addition, long cycle periods reduce the number of flow optimised components required for reliable, integrated performance, such as KAESER’s pre- and after-filters.

Made from activated aluminium oxide, the desiccant has an exceptionally high adsorption capacity and its regeneration capability provides sustained low-pressure dew point performance with minimal pressure loss. The desiccant is also waterproof and mechanically stable, which makes it particularly suitable for long periods of operation. Furthermore, specific pellet sizes are available to ensure optimal performance of flow diffusers and sieve plates.
