IVAR.LONG 500 antifreeze with inhibitor for heating and solar systems – concentrate, 5 l – SALE

Product detailed description

Application

IVAR.LONG 500 protects heating and solar circuits against freezing. It is suitable for all types of heating systems, including underfloor heating and systems with aluminium radiators. The added inhibitor reduces the risk of corrosion and limits limescale deposits. Code IVA.005.L500 is the 5 l pack.

Dilution by minimum temperature

• protection down to −3 °C: 12% concentrate and 88% water
• down to −6 °C: 18% and 82%
• down to −10 °C: 25% and 75%
• down to −15 °C: 32% and 68%
• down to −20 °C: 40% and 60%
• down to −25 °C: 47% and 53%

The mixing ratio stated on the product label is binding. For protection down to −20 °C, for example, the 5 l pack makes approximately 12.5 l of ready-to-use mixture.

Filling and checks

Before filling, check that the circuit contains no residues of acids, alkalis, oils, other antifreezes or inhibitors, refrigerants, abrasives or other foreign substances, and remove them if necessary. Drain the water from the system and determine its volume; use this and the lowest expected temperature to calculate the amount of concentrate. Fill the water mixture from the lowest point if possible, so that the fluid does not take in unnecessary air. After about 2 hours of operation, check the concentration and the contamination of the filters; the next check follows within 24 hours at the latest. At least once a month it is recommended to check the pressure and filters, measure the concentration with a propylene glycol refractometer and monitor the pH, which must not fall below 7.5.

Note: do not mix with other products, as precipitates or deposits may form or the system may be damaged. Wear safety goggles and gloves when working. Store in tightly closed containers at 5 to 35 °C, away from direct sunlight. The same mixture is also available in 30 l (IVA.030.L500) and 60 l (IVA.060.L500) packs.

Technical data

Frequently asked questions

How much IVAR.LONG 500 concentrate do I need?
It depends on the water volume of the system and the lowest expected temperature. For protection down to −20 °C, for example, 40% concentrate is mixed with 60% water, so the 5 l pack makes approximately 12.5 l of ready-to-use mixture.

Is the mixture suitable for systems with aluminium radiators or underfloor heating?
Yes, the manufacturer specifies it for all types of heating systems, including those with aluminium radiators and underfloor heating.

Can I top it up in a system containing a different antifreeze?
No. Before filling, other antifreezes, inhibitors and other foreign substances must be removed from the circuit. Mixing with other products can cause precipitates or damage the system.

How do I check the condition of the fill?
Measure the concentration with a propylene glycol refractometer and regularly check the pH, which must not fall below 7.5. Pressure and filters should be checked at least once a month.
