Customer benefits

  • Installation anywhere, everywhere
    • HVAC system designer can play with weight distribution and space organization on e.g. building roof
    • Flexible HVAC plant design and/or aesthetic view. Each module can be installed differently
      • E.g. different roof corners, different floor levels, etc…
  • Non-stop continuous operation
  • Just in time system
  • Easy to handle
    • Perfect for project with limited access
    • Perfect for city center project where roof access is not allowed
    • Perfect for retrofit
  • Flexible and Optimized investment
    • Spread investments with extending capacity step-by-step
    • Add a modular unit only when more capacity is needed, without any cost penalty
    • Without any restrictions at any time of the project without having to initally planned for additional capacity up to 6 units up to 810kW

FlexMaster Controller

  • Control up to 6 units, of equal or different capacity   (2-pipe systems)
  • Hydraulic kit control: management of external water pump group or water pumps integrated in each unit
  • Set point management: adjustment based on inlet or outlet water temperature as provided by the probe
  • RS 485 serial communication between modular unit(s) and FlexMaster controller
  • Multi-language interface
  • PVC box with transparent door, UV resistant & IP Class 66
  • Potential free contacts for generic alarm signals and for water pump activation
  • Potential-free contacts for:
    • Activation of the system
    • Seasonal setting adjustments with external signal
    • Possible alarm state of external water pump(s)
    • Double set point management
  • BMS connection via Modbus protocol / RS485
  • Input & output probes for the main user
  • External air probe
  • Probes for secondary user temperature control like total or partial recovery and DHW (only if required)

FlexMaster anywhere, everywhere

  • Ideal for connecting multiple Flex modular units to one single “Master controller”
  • For expanding capacity of chiller/heat pump plant
  • To control the main functions and operating modes of the modular units
  • Non-stop operation!  In case of preventive or corrective maintenance necessary on one module all other modular units keep on running
  • Back-up or stand-by capacity!
    • Number of installations with a request for back-up or stand-by capacity is increasing (e.g. hospitals, banks, data centers, high class apartment buildings, etc…..)
    • Traditional systems require a second unit with similar capacity.  Flex modular systems reach same effect by simply adding a modular unit
    • Control up to 6 units of equal or different capacities
