Chilled water units

Van Halteren Naval Technologies designs, manufactures and services (100% oil-free) chilled water units based on a modular design and customised to customer specifications. We have successfully introduced the latest generation of chiller units based on magnetic bearing supported, oil-free compressor technology, into the maritime market. This technology has already been installed on submarines, frigates, corvettes, minehunters, logistic support ships and mega yachts.

  • compressor with magnetic bearings
  • 100% oil-free, reduced complexity and improved heat transfer efficiency
  • low noise & vibration level
  • low weight and compact size
  • high partial load efficiency (coefficient of performance)
  • soft start (< 2 amperes)
  • low maintenance costs, no wearing parts, shock resistant
  • improved MTBF times
  • by using plate exchangers, less refrigerant is required, therefore less polluting


Collective protection against Nuclear, Biological and Chemical (NBC) agents.

For over 25 years, Van Halteren Naval Technologies has been supplying in-house developed NBC filter systems for naval vessels around the world.

  • Complete collective NBC protection with overpressure control in the citadel and sub-citadel
  • STANAG 4447 or ANEP 57 compliant NBC filter units
  • AEP 54 compliant NBC filter units
  • Hull mounted or freestanding
  • Capacity from 600 to 4800 m3/hour
  • Easy filter change, e.g. from the exterior of the ship
  • Integrated electrical panel and control system, including PLC for intrinsically safe operation and alarms
  • Communication with IPMS via CAM, Modbus or Profibus
  • Also suitable for retrofitting
