Pump station FlowSol® Sensor
The FlowSol® Sensor is a complete pump station that integrates the vital electric and hydraulic components of the solar system along with the necessary sensors in one pre-assembled unit. The separate installation of collector and storage sensors is not required. Upon entering the necessary variables such as the geographical position and the tilt of the collector, an innovative algorithm calculates the optimal working time-frame for the solar gain.
The FlowSol Sensor provides the functionality and the efficiency of a standard solar thermal system at an even better reliability rate, while requiring less installation effort.

Heat transfer fluid
Tyfocor® L
Tyfocor® L is a long-time, anti-freeze and corrosion-protection concentrate for cooling and heating systems as well as for solar and heating pump systems. When the circuit system is being filled, 25 up to 75 volume percent of neutral water should be added to the Tyfocor® L. The concentration of corrosion-inhibitors in Tyfocor® L provides long-term protection against corrosion, premature failure and scaling of components and materials. Tyfocor® L keeps the heat transfer area clean and thus assures a constantly high efficiency of the system. Tyfocor® L is suitable for continuous temperatures of up to 170 °C.
Example mixing ratio Tyfocor® L:
1 tank Tyfocor® L + 15,6 l water = 26 l readymix with 40 Vol % (-23,7 °C)
Tyfocor® LS
Tyfocor® LS is a ready for use, vaporisation-safe special heat transfer fluid on the basis of propylene-glycol. It is especially developed for use as a heat transfer fluid in solar heating systems which are capable of a high thermal load. (e.g. in vacuum-tube-collector systems). In order to keep its special properties, Tyfocor® LS must not be mixed with other heat transfer fluids or be diluted with water! Any loss in liquid can only be compensated by Tyfocor® LS.
Tyfocor® G-LS
Tyfocor® G-LS is a ready for use, vaporisation-safe special heat transfer fluid on the basis of propylene-glycol and was especially developed for use as heat transfer fluid in solar systems with direct discharge-flow through flat plate glass collectors. The properties are similar to those of Tyfocor® LS.
®Antifrogen SOL
®Antifrogen SOL is a ready for use, vaporisation-safe heat transfer fluid on the basis of propylene-glycol and higher boiling glycol. It is physiologically harmless and contains corrosion-inhibitors that will thoroughly protect all materials usually used in heating and solar thermal systems against corrosion, premature aging and incrustation. ®Antifrogen SOL HT will not segregate, withstand high operating temperatures and is suitable for both flat plate and vacuum tube collectors.
®Antifrogen SOL HT
®Antifrogen SOL HT has the same properties as ®Antifrogen SOL, but is predominantly based on higher boiling glycol, which makes it withstand operating temperatures of up to 200 °C and even extremely high standstill temperatures of up to 270 °C without decomposition. Hence it is particularly suitable for solar systems with a very high thermal load. ®Antifrogen SOL HT also offers a full frost protection up to -23 °C which will not diminish even after long-standing usage.
- Use only antifreeze-protection which is suitable for solar heating systems
- Materials within the collector-circuit have to be glycol-resistant
- A verification of a labelling and a classification in terms of appendix I Nr. 1.1 the Gef-materialV of the antifreezeprotection material inquired from the producer
- Never use tin in the collector circuit, it will be dissolved by the glycol
- Concentrations of more than 50 % of glycol are to be avoided, they can cause damage to the expansion vessel. Higher pump power is required, this unnecessarily reduces the efficiency of the system
Please note:
ALS15 discharge hose
At the safety valve outlet of a solar thermal or heating system, it can get pretty hot at times. The RESOL ALS15 sees to it that no-one gets hurt and nothing gets soiled when that happens.
The robust, heat resistant EPDM hose fits all common ¾“ safety valve outlets, can be individually shortened and is easy and effortless to install.
Wall mounting for expansion vessel
Wall mounting for expansion vessel with screws and dowels, high grade steel corrugated tube and connection thread ¾"
LT20 air separator
A solar thermal system has to be vented regularly in order to function efficiently. The RESOL LT20 air separator, installed in the solar flow line, permanently separates the air from the heat transfer fluid.
With the venting nipple and the hose included, the collected air can be discharged manually.
Filling and injection pump
Filling and injection pump with non-return valve for pressure increase and refilling of heat transfer fluids. ½" OT self-sealing with O-ring, 15mm tube connection, pump output 2 l/min, 4,5 bar max.
VM1020 flowmeter
A correct flow rate is vital for the function of a solar thermal system. The RESOL VM1020 flowmeter indicates flow rates from 1 to 10 litres per minute, with the integrated flow rate limiter, the value can be throttled.
With the also integrated fill/drain valve, flushing and draining processes can be carried out; an opening for the immersion sensor enables an easy return temperature measurement.
