Kaeser Expands Secotec Dryers with New TF Series

Secotec Dryer

New Secotec TF dryers with SECOPACK LS deliver higher energy efficiency and better dew point control in a smaller footprint.


The new TF series, with four models from 550-1130 scfm, integrates Kaeser’s innovative SECOPACK LS latent heat thermal storage system that delivers consistent dew point control and energy efficiency under varying load conditions. SECOPACK LS contains a phase-changing material (PCM) that stores thermal energy as it cycles from a solid to a liquid state, greatly enhancing energy efficiency. The PCM module is 98% denser than conventional storage media. This, combined with topside air exhaust, creates a smaller overall footprint for the dryer. 

TF dryers also feature a variable speed radial fan design that improves cooling and enables ducting and heat recovery. A dedicated fan in the electrical cabinet and optional water-cooling allow operation in high heat environments without loss of drying capacity. The SIGMA CONTROL SMART microprocessor controls the thermal storage process and provides both a remote on/off control capability and optional Ethernet interface so TF units can be easily integrated into plant operations and IIoT environments. 

The TF dryer completes the transition to the advanced R-513A refrigerant in the SECOTEC line. With its 56% lower global warming potential, the use of R-513A is a clear demonstration of Kaeser’s ongoing commitment to preserving our shared environment for future generations.
