Additional Information	N/A 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. Exceptional durability due to corrosion-resistant air piping and aluminum heat exchanger (condenser and SECOPACK LS) With Modbus TCP communication module for integration in the SIGMA NETWORK
Advantages	N/A Energy savings - TF refrigeration dryers require less than 97 W for every cfm of air to be dried (ISO 7183 A1) Thanks to energy-saving control, in partial-load operation, excess cooling power can be temporarily stored in the thermal mass for later cooling without the need for power consumption. The rapid-response SECOPACK LS heat exchanger system ensures stable pressure dew points at all times. Intuitive operation - The SIGMA CONTROL SMART electronic controller offers straightforward and intuitive operation. Message memory, component-specific operating hours counters and maintenance timers enable efficient monitoring and analysis of operating data. Floating contacts and the Modbus TCP communication module provide easy networking with master controllers such as the SIGMA AIR MANAGER 4.0. Optimized compact design - The thermal mass chamber 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. Storage capacity for pressure dew point stability therefore goes hand in hand with hugely reduced space requirements. Optimized flow paths minimize pressure losses and consequently help enhance SECOTEC dryer efficiency.
Reduce Life-Cycle Costs!	N/A Thanks to cycling control mode and high storage density, the new generation of SECOTEC refrigerated dryers requires less than 97 W for every cfm of air to be dried (ISO 7183 A1) - almost regardless of load. In contrast to other typical systems on the market, excess cooling power is not wasted, but rather used to cool a thermal mass. Once cooled, it in turn supplies cooling for compressed air drying, eliminating the need for additional electric power. Furthermore, the new design ensures minimal maintenance and service work is quick and easy.
SECOTEC - Always Saving Energy	N/A The load on a refrigerated dryer doesn't just depend on the volume of compressed air to be dried (grey area), but more importantly depends on how much water the incoming compressed air contains. The volume of water (moisture) increases as the temperature rises, so the load on refrigerated dryers increases dramatically when ambient temperatures are high, such as during summer (yellow curve). Conversely, when the temperature drops during the winter (turquoise curve), there is less load on refrigerated dryers. To maintain a stable pressure dew point throughout these fluctuations, refrigerated dryers should be designed to provide sufficient performance during peak load times, and have additional reserve capacity. Like the flow rate and temperature range, refrigerated dryers are always operating within the load range of 0 to 100 %. Because SECOTEC storage control ensures energy is only used as needed across this entire load range, users benefit from exceptional savings.
R-513A: A Future-Proof Refrigerant	N/A The use of small volumes of the future-proof R-513A refrigerant provides security of supply for maintenance work throughout the entire life of the refrigerated dryer. Innovation - The use of greenhouse gases is becoming ever more strictly regulated throughout the world. Installation of highly compact heat exchangers - such as SECOPACK LS and micro-channel condensers - considerably reduces refrigerant demand. The greenhouse gas potential of R-513A is significantly lower compared to the refrigerants that have commonly been used in refrigerated dryers up until now. R-513A is equivalent to R-134a. It is neither toxic nor flammable.
Maximum Energy Savings Thanks to Storage Control	N/A The duty-cycle of refrigerated dryers is always fluctuating between 0 and 100 %. Unlike conventional part-load control systems, SECOTEC storage control precisely adjusts electrical power consumption during all load phases. This allows SECOTEC refrigerated dryers to save almost 60 % of energy costs compared to refrigerated dryers with hot gas bypass control running at an average of 40% of capacity. In contrast to conventional systems, the thermal mass in SECOTEC dryers always remains cool. This means compressed air can be dried effectively even during start-up phases. The high-quality insulation around the thermal mass also helps to keep energy use to a minimum. With SECOTEC refrigerated dryers, you get compressed air drying with outstanding energy efficiency. The high thermal mass capacity dries with reduced component wear and tear.
Optimal Drying with Low-Wear Operation	N/A SECOTEC refrigerated dryers ensure stable pressure dew points in all load phases. Dried compressed air can cool to a temperature of + 38ºF (= achievable pressure dew point) without the moisture in the air condensing. Even at higher ambient temperatures, this ensures optimal protection for downstream compressed air systems and points-of-use. Conventional refrigerated dryers with switching operating modes, but without an additional thermal mass, use the heat exchanger material itself as a thermal mass. In these dryers, it is therefore necessary to switch the refrigerant compressors and fan motors on and off much more frequently in order to maintain the required cooling performance. To reduce switching frequency and wear, the refrigerant circuit therefore only switches on at much higher pressure dew points. The resulting fluctuations in the pressure dew point negatively affect drying performance. This can be risky, since corrosion can occur even with relative compressed air humidity of 40 % - corrosion can therefore occur even without condensate forming. SECOTEC refrigerated dryers, on the other hand, ensure material-friendly operation thanks to their high thermal storage capacity. Once the thermal mass has been charged, the refrigerant compressor and fan motor can remain switched off for much longer periods of time without impacting pressure dew point stability.

SECOTEC - Industries 4.0 Ready	N/A With the Modbus TCP module, SECOTEC refrigerated dryers can be easily integrated into the SIGMA NETWORK. All essential operational parameters and messages are available in real-time. This enables comprehensive system monitoring of the entire compressed air station and creates the basis for needs-based preventive maintenance. The result: Maximum availability with minimal costs. In addition, SIGMA AIR MANAGER 4.0 provides a complete overview of all essential operating parameters of the refrigeration dryers. Color-coded warnings and alarms are displayed in the compressed air station's P&I diagram. By clicking the dryer icon, all key operational parameters and message texts are displayed in plain text.
SECOPACK LS - The Efficiency Module	N/A TF series refrigeration dryers are equipped with the innovative SECOPACK LS heat exchanger system. Its latent heat thermal mass is composed of a phase change material. Compressed air warms the material until its melting point (thermal mass discharge), absorbing latent melting heat in the process. This is significantly greater than the amount of heat that it can absorb based on its normal specific heat capacity (without phase change). The latent thermal mass in TF series dryers therefore has a significantly higher thermal storage density and requires 98 % less storage material to achieve the same capacity as conventional storage media. The key advantages: high thermal capacity for stable pressure dew points and material-friendly operation combined with dramatically reduced unit footprint.
