Energy-saving SECOTEC refrigerated dryers, 1340 - 3070 scfm

SECOTEC TG: Compact giants

With the new TG series, KAESER extends its range of energy-saving SECOTEC refrigeration dryers to accommodate flow rates up to 3070 scfm and offers models with a choice of air- or water-cooled models.

Designed for large-scale industry, these compact powerhouses ensure stable pressure dew point performance even under the toughest of operating conditions - with maximum reliability and minimal life cycle costs. The powerful cold storage concept, together with the standard, network-capable SIGMA CONTROL SMART controller guarantee long-lasting, energy-saving operation in all load phases. The innovative exhaust air control, fitted on air-cooled variants, sets new standards for operational reliability and cost efficiency.

Your advantages

  • Improved operational reliability:
    In combination with a high-efficiency radial fan, the innovative exhaust air control in SECOTEC TG refrigeration dryers ensures optimal system cooling. This not only opens up new savings opportunities when it comes to planning and installation, but also significantly contributes to efficient and material-friendly operation of large refrigerated dryers.
  • Future-proof investment:
    With the climate-friendly R-513A refrigerant, KAESER offers the best solution currently available to assure future supply dependability. This effectively prevents high repair costs and the threat of shutdowns.
  • Reduce operating costs even further:
    The high-performance thermal mass concept with SECOPACK LS and perfectly matched multiple compressors, SECOTEC TG refrigeration dryers boast exceptionally efficient partial load control for flow rates up to 3070 scfm within an impressively compact unit that requires minimal maintenance.
 

Product details

Innovative exhaust air control with radial fan
The key innovation in the new SECOTEC refrigerated dryers is their radial fan.

Significant space-savings reduce planning and installation costs. Stable pressure dew point performance combined with material-friendly, energy-saving operation thanks to optimal system cooling.

Innovation:

  • According to load, the frequency-controlled radial fan draws off the accumulated exhaust heat from the refrigeration dryer via the cooling air flow.
  • The radial fan is sufficiently powerful to allow standard exhaust air ducting to be connected directly to the refrigeration dryer.
  • The high efficiency dimensioning of the radial fan is also reflected in the low power consumption performance of SECOTEC TG refrigeration dryers.
  • Thermal overload - caused by hot exhaust air being drawn back in as cooling air - is safely avoided.
  • Compared to conventional ventilation systems using air hoods and auxiliary fans: No unnecessary removal of air from the room. This minimizes exhaust air flow which means smaller diameter ducting can be used. There is no longer any need for an auxiliary fan. 
  • Independent exhaust air control and high residual thrust allow direct connection to the compressor collector ducts.  
R-513A: A future-proof refrigerant
R-513A

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.
