• Servitec Mini


    Vacuum spray tube degassing for small systems.
    Water quality has a huge impact on the operating behaviour of water heating and cooling systems. Only systems that are running to the best of their capacity function efficiently and economically. With its high level of efficiency when it comes to degassing the facility water, the Reflex Servitec Mini makes a significant contribution in this regard as the hydraulic balancing is perfected.

"Reflex vacuum spray tube degassing is recognised as one of the most efficient systems on the market in heating and cooling applications."
Helmut Brinkmann, Product Manager

Here's how it works

A vacuum spray tube is used to de-gas system water.

  1. Gas rich system water is sprayed through a nozzle into the spray pipe.
  2. A pump sucks the water out of the spray tube and pumps it back into the system.
  3. The configuration ensures that the pump extracts more water from the pipe than can flow in through the nozzle. This creates a vacuum in the spray pipe, which causes the degassing effect.
  4. If the pump is turned off, water flows into the spray pipe and forces the removed gas outside via air vent

The medium, which is now unsaturated, is able to absorb new gases in the facility system once again, thereby steadily reducing the gas concentration in the entire facility network.

Our tip: the automatic make-up can take place independently via the Reflex Fillcontrol Plus Compact.


Easy installation and commissioning:

  1. Mount the pre-installed pipelines onto the device.
  2. Install the Servitec Mini onto a wall using the holes provided on the rear side of the housing.
  3. Hydraulic connection: a degassing line to the facility system (high-gas), and a degassing line from the facility system (low-gas), viewed in the direction of flow in the system.
  4. Open the ball valves of the device.
  5. Establish a power supply. The device starts in commissioning mode (Auto LED flashes green).
  6. Press the Auto button, if the LEDs on both buttons are unlit. Continuous degassing starts (4-6 h)

Please refer to our detailed operating instructions during installation and commissioning.


Product details

Compact vacuum spray tube degassing with automatic operation

Reflex Servitec, vacuum spray tube degassing for system degassing in closed heating and cooling circuits, configured as a fully automatic multi-function unit with auto-stop operation and automatic hydraulic compensation of the degassing process and monitoring of replenishment.

Functional unit comprising hydraulic part designed for wall mounting and electronic, ergonomically arranged Reflex mini controller unit with CE marking.

Degassing takes place within the hydraulic part using a diaphragm pump in conjunction with a vertically arranged brass vacuum spray tube. This is equipped with a vacuum spray nozzle, dipstick-tube degassing unit and pressure monitoring. The unit as a whole is located in a dirt-protected housing made from expanded polypropylene that can be opened on the front side.

The Reflex Mini control unit is integrated in a robust plastic housing in which both the power and communication electronics and the control panel with dirt-resistant membrane-covered keyboard is housed.

The Reflex Mini control unit is a fully automatic microprocessor control unit with time function, differentiating error and parameter memory, LED display of the operating modes and general error messaging, visualisation of the control states for system pressure and all relevant operating and fault messages.

Control unit completely piped and wired ready for connection according to VDE regulations, mains power cable and mains plug, system connections by means of integrated shut-off valves.

Method of working in optimised operation with cycles for continuous and interval degassing. Actuation takes place via an integrated system pressure interpretation unit with automatic interruption and fault messaging upon exceeding of the running time and/or the number of cycles. Documentation and control of the entire system in respect of the above mentioned parameters.
