reflex ’servitec 30’Vacuum spray degassing unit
Assembly, operation and maintenance manualdated 09/11
’servitec 30’ is a degassing and make-up station for heating and cooling systems that mainly consists of a control unit and a special pump.
Assembly and operationAssembly and operation are performed according to national regulations; in Germany this is the Ordinance on Industrial Health and Safety (Betriebssicherheitsverordnung). In keeping with this, assembly and operation must be performed according to the state of the art by qualified personnel and specially trained staff. Important: ’servitec 30’ is designed for stationary, not for mobile system opera-tion. The set warranty periods are only valid if a maximum of 10,000 degassing intervals per year are observed.
Adherence to parametersDetails concerning the manufacturer, year of manufacture, and serial number as well as technical data are provided on the name plate. Suitable temperature and pressure protection measures must be implemented in the supply system to ensure adherence to the specified permissible maximum and minimum operating parameters. This system may only be used in systems with nontoxic waters.
Thermal protectionCare must be exercised when working on a hot system. There is a risk of scalding from water escaping at the screw connections, the bleed screw for the pump, and the dipstick-tube degassing unit in particular. A risk of injury due to high tempera-tures arises especially from touching the pump casing.
Electrical connectionElectrical wiring and connection must be performed by a qualified electrician according to the applicable local regulations (electricity board, VDE and EN). The system must be de-energized before any work is carried out on electrical compo-nents.
Failure to keep to these instructions, in particular the safety instructions, may result in the destruction of and defects in the ’servitec 30’, personal injury and impaired operation. Any and all claims for warranty or liability are excluded if these regulations are violated.

Mode of operation
General description’servitec 30’ is a degassing and make-up station. It can be used in a wide range of system conditions. The main field of application is heating and cooling circuits and wherever air problems in the form of dissolved or free gases cause problems in systems.The ’servitec’ vacuum spray-tube degassing system removes up to 90 % of the dissolved gases from the system water. Vacuum degassing of a part flow of the circuit water takes place accord-ing to an optimized schedule using selectable degassing programs (→ p. 13).A part flow of the circuit water is sprayed through the nozzle (7). The vac-uum is created by the pump (6). The large surface area of the sprayed water and the intense vacuum result in the extremely high degassing per-formance. The degassed water is returned to the system. There the water is again able to dissolve gases. The gases separated in the pump (6) are expelled using the dipstick-tube degassing unit (5). This degassing inter-val is repeated and free as well as dissolved gases are removed from the circuit water.
Degassing intervalThe degassing interval is a time-controlled, pre-programmed process that consists of the degassing time, expulsion time, and idle time. The time periods can only be changed in the service menu by Reflex Service.The degassing intervals are repeated according to the continuous degassing mode (standard = 5 h a day) or interval degassing mode(standard = 16 x a day).
Injection timeThe pump (6) starts. A vacuum (dependent on temperature) can be read off the display (→ p. 3) after a short time. This is possible because the pump (6) draws more water from the pump casing than is able to flow in via the pressure supply port with nozzle (7). Spraying via the nozzle commences as soon as the vacuum begins to be established.The water level in the pump casing (6) drops continuously while the pump (6) is running. The timing program and pressure setting have been selected so that the pump does not become low in water.
Expulsion timeThe pump (6) switches off. The water continues to be sprayed into the pump casing by the system pressure (at least 0.5 bar). The water column in the pump casing rises gradually during the expulsion time. The vacuum is still maintained during this phase of the interval. At the end of the expulsion phase, the rising water column compresses the removed gas within a few seconds, expelling it into the atmosphere via the dipstick-tube degassing unit (5).
Idle timeThis is followed by the idle time during which redegassing takes place.
Make-upIn the case of the ’servitec 30’, the pressure in the heating or cooling system is registered and monitored with the help of the pressure transducer (8). If the fill pressure drops below pF = p0 + 0.2 bar, make-up degassing is activated until pF = p0 + 0.3 bar has been reached. Time (20 min default setting), cycle (3 in 2 hours) and volume monitoring are active during this process.The motorized ball valve (2) opens during make-up. During pump operation, a pressure of approx. - 0.6 bar is set in the pump casing (pressure indicator display). In the event of a cyclical pump stop, the system pressure is checked and made up if necessary.

Automatic mode
Automatic mode may only be activated after initial start-up has been successfully completed. If you are in automatic mode, you can select from three degassing programs, if required. System monitoring is active with all three programs. Make-up takes place automatically. Selection in customer menu (→ p. 9) Continuous degassing – Intensive degassing following start-up and
repairs The degassing cycles are executed successively for the set
continuous degassing time (basic setting: 5 h). The controller then automatically proceeds with interval degassing. In the case of water systems, at least half the system volume should flow through the ’servitec’ unit once during start-up. Based on a system volume of 8 m3, this is equivalent to approx. 22 h of continuous degassing. In systems that are particularly rich in gas, a continuous degassing period of 48 h is completely sufficient. As a result of the subsequent interval degassing, 10,000 intervals are made per year. This number per year must not be exceeded in order to avoid unnecessary wear to the ’servitec’. The controller registers the total number of intervals that have passed.
Interval degassing – Economy mode in automatic mode After 8 intervals (standard), a break (standard 23 h) is observed
before the next 8 degassing intervals are started. This program is automatically started upon completion of continuous degassing or can be selected manually for systems already degassed. Interval degassing then starts at 08:00 each day.
No degassing – Only make-up The system water is not degassed. This operating mode is practical
during summer operation or if general degassing of the system water is not required.
