Refrigeration Dryers Flow rate 0.6 to. m³/min
Energy savings all day, every day SECOTEC refrigeration dryers 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. Reliable compressed air drying 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. Premium components High quality, generously-sized components (e.g. in the condenser) ensure optimum flow at all times even at high operating temperatures and guarantee a long and dependable service life. Details such as the use of smooth-bore copper piping in the refrigeration circuit also contribute to exceptional system effi ciency. Impressive performance and efficiency KAESER KOMPRESSOREN s innovative SECOTEC system is a true energy-saver when it comes to compressed air drying: unlike most refrigeration drying systems, KAESER SECOTEC energy-saving dryers consume power only when air actually needs to be dried thanks to their highly effi cient cycling control. Perfect for compressor stations Every SECOTEC dryer is EN 600- compliant and is tested for electromagnetic compatibility. Unlike equipment conforming to VDE 0700, SECOTEC dryers conform to a strict industrial standard and are equipped with a control cabinet to IP 5, a control transformer and fuses for the control and power circuits. The whole system is designed with maximum safety and reliability in mind. Reliable refrigerant circuit The refrigerant circuit in SECOTEC TF refrigeration dryers is specially designed for effi cient use of R-a refrigerant. This ensures maximum effi ciency and reliability, even at higher temperatures. Image: SECOTEC TB 9
Quality counts SECOTEC with thermal mass Hot gas bypass continuous control Reliable refrigerant circuit The refrigerant circuit in SECOTEC TF refrigeration dryers is specially designed for efficient use of R-a refrigerant. This ensures maximum effi ciency and reliability, even at higher temperatures. Saves energy: SECOTEC control The SECOTEC cycling control signifi cantly reduces energy consumption compared with conventional systems with continuous control. The refrigeration circuit is activated only when cooling is actually required. Image: SECOTEC TE 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. 5
Quality engineered Efficient condensate separator KAESER s corrosion-free stainless steel condensate separators provide dependable compressed air drying and ensure reliable condensate separation even at partial load. This is especially important for compressor systems with standby dryers. Control cabinet to EN 600- The electrical components in SECOTEC dryers are designed and built in accordance with European standard EN 60- and applicable EMC standards. The dustand splash-proof IP 5 enclosure ensures maximum safety and durability at all times. Dependable condensate drainage Fitted as standard (except for the TA 5 model), the ECO-DRAIN is equipped with an intelligent levelsensing control that prevents pressure loss when the condensate is drained from the air system. Dependability to + C Thanks to perfectly matched refrigeration circuit components, SECOTEC dryers provide dependable performance at ambient temperatures of up to + C. 6 Image: TE 6 internal view 7
Easy to maintain Maintenance-friendly design All components in SECOTEC dryers are easily accessible. Furthermore, the condenser is located at the front of the dryer, which allows possible dirt accumulation to be quickly spotted and rectified. Excellent accessibility The SECOTEC refrigeration dryer s enclosure covers are quick and easy to remove. The tower design makes maintenance a breeze, which signifi cantly reduces servicing requirement and therefore costs. Easy-to-test refrigeration circuit KAESER service technicians and our partners technical staff are refrigeration technology experts. They not only check operation of the refrigeration dryer, but also of the cooling circuit itself using intake- and pressure-side service valves. Dependable condensate drainage Condensate drains play a key role in ensuring dependable operation of SECOTEC energy-saving dryers. The electronic ECO-DRAIN condensate drains are therefore subject to regular scheduled maintenance and inspection. 8 9

This cost saving is calculated as follows: (8760 h - 000 h) x.5 kw x 0.0 /kwh = 785 The graph shows a typical compressed air consumption profile. SECOTEC dryers save energy because the refrigerant system is shut down during breaks, periods of low demand and downtime the control system operates without fixed run-on periods. The integrated thermal mass ensures that the system is always ready for operation. 0
Equipment General design Tower construction with removable side panels, sheet steel panelling powder-coated outside and galvanised inside; all cold components insulated; all materials CFC-free; the built-in control cabinet is enclosure-protected to IP 5, air to air heat exchanger (model TA 8 upwards); condensate separation system, automatic condensate drain; scope of delivery includes refrigerant and oil. Operating panel Equipped with dew point trend gauge, emergency stop switch, LEDs to indicate Thermal mass active and Refrigerant compressor ON. LEDs for High dew point and ECO- DRAIN alarm are fi tted as standard on TE models and upwards. TF models and upwards feature two operating hours counters. Refrigerant circuit Refrigeration circuit features large heat exchanger surface area and service valves, SECOTEC cycling control with thermal mass and automatic dew point control. Installation example Installation example For generally consistent air demand, the SECOTEC refrigeration dryer is located downstream from the air receiver. For heavily fl uctuating air demand, the SECOTEC dryer is located between the compressor, centrifugal separator with condensate drain and air receiver.
