Energy-Saving Refrigeration Dryers SECOTEC® TE, TF and TG Series Efficient, compact and maintenance-friendly Flow rate 10.5 to 98 m³/min, Pressure 3 to 16 bar

Compact, energy-saving refrigeration dryers with impressive latent heat storage KAESER’s renowned industrial-quality SECOTEC series refrigeration dryers have long been valued for their stable pressure dew point performance, exceptional reliability and low life-cycle costs. Now, the enhanced second generation offers even greater efficiency with a more compact design and further-optimised user-friendliness, thanks to such features as: the compact SECOPACK LS heat exchanger system with its high-efficiency latent heat storage, the standard-equipped, network-capable SIGMA CONTROL SMART controller...

Efficient, compact, maintenance-friendly

Energy-efficient powerhouses Consistent use of high-quality components and our decades of experience in system design enable SECOTEC refrigeration dryers to achieve world-class energy efficiency – across the entire load range. Efficient refrigerant compressor Minimal differential pressure The scroll refrigerant compressors used in SECOTEC dryers are up to 26% more efficient than reciprocating compressors. They therefore play an important role in ensuring the outstanding efficiency of KAESER refrigeration dryers. Second generation SECOTEC refrigeration dryers stand out for their remarkably low...

Reliable drying We do not just talk about challenging operating conditions, but actually create them using our advanced climate testing facilities. This allows us to fine-tune the design of SECOTEC refrigeration dryers in order to ensure maximum reliability at all times. Controlled availability Compact condenser The innovative SIGMA CONTROL SMART controller regu‑ lates the operation of the thermal mass whilst constantly monitoring system temperature and pressure values. Automatic wire break and short circuit monitoring add even greater operational security. Aluminium micro-channel condensers...

Easy installation and excellent accessibility KAESER understands our customers' needs very well, as the company itself operates numerous compressed air stations. From first-hand experience, we are well-versed in all aspects of compressed air station planning, commissioning, operation and maintenance. We draw on this expertise to create user-friendly products with minimal need for maintenance. Left-hand side compressed air connections (optional) If required, SECOTEC TF refrigeration dryers are available with compressed air connections located at the top of one side. This customised solution enables...

On TG series units, maintenance access is provided via large doors. The micro-channel condenser is also easily accessed for cleaning. ...with just one wall side Two energy-saving refrigeration dryers and not much space? No problem! TE, TF and TG series refrigeration dryers are equipped for back-to-back installation. The SECOTEC TG series combines maximum performance with a minimum need for space. Even installation against...

SIGMA CONTROL SMART The new generation of SECOTEC refrigeration dryers is equipped with the SIGMA CONTROL SMART electronic controller. With its colour display and language-neutral menu navigation, this advanced controller is exceptionally user-friendly. Operational status can be viewed at a glance via the dew point trend indicator, prominent display of active messages and current operating data, as well as a clearly arranged P&I diagram. Furthermore, a message memory and floating message contacts, together with the standard-equipped network interface, provide highly effective analysis and monitoring...

- Maintenance/warning: indicated in orange - Faults: indicated in red - Unacknowledged message: indicated by a border - Messages identifiable by numerical codes - Messages timestamped with operating hours - Counter shows number of past messages - Multiple operating hour counters - Temperature thresholds for messages - Activation of remote on/off - Display of actual electrical power consumption - Estimated energy savings compared to dryers with hot gas bypass control - Change measurement units - Displays functional principle - Messages displayed with coloured switch symbols (e.g. condensate drain...

SECOTEC thermal mass control Innovative energy-saving control with Storage Plus For its Storage Plus energy-saving control, KAESER uses a special phase change material that absorbs latent heat. In contrast to other thermal mass storage systems available on the market, the heat energy does not go through a temperature change; rather, it goes through a phase change. Only when the entire medium has undergone this phase change - meaning that the storage is now full does the temperature begin to rise. When the latent heat is discharged, the phase change reoccurs in the opposite direction, with the...

Modbus TCP communications module SECOTEC – Industrie 4.0 ready maximum air availability for minimal cost. Furthermore, the SIGMA AIR MANAGER 4.0 provides a complete overview of all of the refrigeration dryer’s essential operating parameters. Colour-coded warnings and alarms are displayed in the compressed air station's P&I diagram. By selecting the dryer icon, all key operational parameters and message texts are displayed in plain text. With their standard-equipped Modbus TCP module, SECOTEC refrigeration dryers can be connected to the SIGMA AIR MANAGER 4.0 and the SIGMA NETWORK. All essential...

The high-efficiency module for maximum energy savings Second generation SECOTEC 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 up to its melting point (thermal mass discharge), absorbing melt heat during the process. This is significantly more than the amount of heat that it can absorb based on its normal specific heat capacity (without the phase change properties), so the latent heat thermal mass in SECOTEC dryers has a dramatically higher thermal density...
