Cooling units

Water-cooled system for low working temperatures with water glycol:from -25°C to +25°CTT-29'800 WK

Summary

  • Temperature range -25°C bis +25°C
  • Medium water
  • Cooling capacity 54 kW nominal
  • Pump capacity 140 l/min; max. 4.8 bar
  • Refrigerating agent R-404a
  • Ambient temperature up to +45°C

Functions

  • Self-optimizing temperature contrtoller with temperature display
    1/10°C – steps
  • Display in °C or °F and l/min or gal/min
  • Digital flow display and monitoring
  • Automatic or manual refill

Working principle

  • As soon as the water supply in the unit has reached the required temperature, the compressor switches off until the temperature rises again
  • The switch-on point can be programmed on the digital controller
  • The circulation pump continues to run continuously

Construction

  • Proven pump with mechanical seal
  • Long life expectancy due to the electronic control of the compressors operting time
  • All parts in contact with water are made of stainless steel or bronze
  • Unit on Castors

Safety features

  • Automatic level control with prewarning at low water level
  • Electronic temperature limitation and monitoring in the controller
  • Mechanical safety thermostats
  • Visual and acoustic fault indications
  • Integrated circuit breakers
  • Main switch, transformer and motor protection switch
