Refractometers for determining the freeze point of various TYFO products

This measurement device enables rapid testing for the antifreeze properties of coolants and heat transfer fluids using the refraction principle (determining the refractive index).

 

Measurement procedure:

Apply 1 to 2 drops of sample liquid to the surface of the prism. Then press the light panel onto the prism surface. Hold the pointy end of the refractometer against the light and turn the eyepiece until the borderline is visible. This line denotes the freeze point of the medium.

Areometer for determining the freeze point of various TYFO products

Areometers are instruments for determining the exact density of liquids or the concentration of substances in solution. They work according to Archimedes’ principle. An areometer consists of a cylindrical stem and a weighted bulb that you float inside a cylinder.

Application:

Approximately 250 ml of the liquid to be tested is poured into the cylinder and brought to +20°C. The areometer is removed from its protective case and inserted into the cylinder to take the measurement. The areometer must float in the medium. If the device sinks to the bottom, more needs to be added to ensure a correct measurement. The measurement is taken by reading how far the stem has sunken into the liquid on the inscribed scale (density in g/cm³). The freeze point can then be determined using the table provided.

Glycol refractometers — instruments used to determine the freezing point of aqueous propylene glycol and ethylene glycol mixtures

These instruments are generally suitable for all concentrations of propylene glycol mixtures or optionally — as a special model — for all aqueous ethylene glycol mixtures. They are able to correctly measure the freeze point of the respective mixture at temperatures between +15 and +70°C. The version intended to measure propylene glycol mixtures cannot be used to measure ethylene glycol mixtures and vice versa.

SOLARCLIN®: Cleaning liquid for solar thermal systems

SOLARCLIN® is a neutral, colourless, slightly hygroscopic, free-flowing, high boiling liquid with a very faint scent. It can be mixed with water and common organic solvents in any concentration desired. Due to its structure, it performs very well as a solvent for impurities that have developed as a result of the heat transfer fluid being exposed to excess thermal stress in evacuated tube collectors.

Application:

The system to be cleaned must first be emptied completely to ensure optimal cleaning since the heat transfer fluid or water would otherwise limit effectiveness. Furthermore, the solar collectors must be covered before the rinsing is carried out. Then the system is filled with SOLARCLIN® at a temperature between 50 and 60°C before circulating for one to two hours. Due to the elastomer materials used in solar systems such as EPDM etc, higher temperatures should be avoided.

Depending on the amount of impurities, the procedure may need to be repeated a number of times. After the cleaning has been completed, the system should be emptied as completely as possible. Any remaining impurities left in the system should then be removed using compressed air.

Measurement and service case

This toolkit for inspecting solar thermal systems includes instruments used to measure solar fluid: refractometer, pressure gauge, pipette, digital multimeter, compass, and other tools and materials.

 

 

Fluid analysis

We offer our customers free testing of heat transfer fluids:

  • Verification of the status of an existing fluid. In this case we assess to what extent the liquid still fulfills the requirements for protection against frost and corrosion as well as long-term stability to determine whether replacement is necessary.
  • Analysis of the operating reliability of systems and testing to determine if corrosion has taken place and if so, what type. For older systems with unknown thermal fluids, we determine the composition and suggest an appropriate alternative for refilling. Should leaks or malfunctions of the system occur, we can use fluid analysis to help determine the source of the problem. For these types of tests, we normally require a 500-ml sample. You get the results within 10 business days, depending on the testing required.
 

TYFO rinsing and filling station

The new TYFO rinsing and filling station makes rinsing and filling closed loop systems such as solar thermal systems and heating systems fast, easy, and clean. The large wheels and ergonomic pushbar make the station easy to maneuver even when it’s full. The impact-resistant 30-litre tank is semi-transparent, making it easy to determine the fluid level at all times.

Our rinsing and filling station is suitable for water, water/glycol mixtures, and cleaning fluids such as SOLARCLIN®. And of course the station can also rinse and fill conventional heating systems.
