KP Secondary circuit systems explosion-protected
  • Stainless steel Kryopac heat exchanger in flange version
  • Use of chilling from evaporating nitrogen; transfer to a liquid heat transfer fluid
  • Saves on energy costs
  • Only one heat transfer fluid
  • No freezing problems with low temperatures in the heat exchangers; the commercially available heat transfer fluid can be cooled down to the solidification point
KP Secondary circuit systems explosion-protected
  • Three-way control valve with bellows and actuator in flange version
  • Stabilization of the lowest cooling power
  • Due to bypass operation, no steam hammering in the heat exchanger
  • Gentle cooling
  • Efficient heating
  • No thermostatic changeover in the heat exchanger on switching from cooling to heating
KP Secondary circuit systems explosion-protected
  • Complete system test in LAUDA Test Bed before shipment; system with CE label
  • Functional testing of all components and checking of all set values
  • Pressure/leakage test with the heat transfer fluid
  • Test of control cabinet and control accuracy
  • Production of a test protocol; documentation of the tests carried out
  • FAT (Factory Acceptance Test) in presence of customer
  • Hot and cold runs with the heat carrier at maximum and minimum operating temperatures
  • Systems quickly ready for operation, short commissioning times
  • Avoidance or prevention of leakage
  • Verification of control accuracy and high-precision processes
  • Check of all performance verifications
  • Systems designed to customer requirements, initial instruction and trial run already before shipment
