Antifreeze Heizungsgold Cooling Brine Concentrate SK, 200 kg in barrel (on pallet)

Heizungsgold Cooling Brine Concentrate SK, 200 kg in barrel (on pallet).
Propylene glycol concentrate with corrosion inhibitors for cooling and heating systems in the food sector.

No return or refund of the containers.

Standard delivery without lifting platform. If required, the lifting platform surcharge will be charged separately.

Mode of action:
Heizungsgold Cooling Brine Concentrate SK is an odourless liquid based on monopropylene glycol which is used in cooling and heating systems, especially in food processing plants, as a cooling brine or cooling or heat transfer fluid. The special corrosion inhibitors protect the metals and plastic materials usually used in plant construction, including copper and aluminium, from corrosion, layer formation and deposits. Thus, the efficiency of the plants is maintained. Sealing materials are not attacked by Heizungsgold Cooling Brine Concentrate SK. 

General information:
Before filling, the system should be rinsed with softened water and checked for tightness of all connections by pressure testing.
and checked for tightness of all connections by pressure testing. The system should be filled with Heizungsgold Cooling Brine Concentrate SK ready for use immediately after pressure testing. Do not introduce air! Galvanised system components should be avoided, as zinc is not resistant to glycols. The heat transfer medium circuit should always be designed as a closed system with membrane pressure compensation vessels according to DIN 4807. Oxygen ingress consumes the corrosion inhibitors. Therefore, only use low-diffusion connecting elements or hoses. Soldered connections should be made with Ag or Cu hard solder, otherwise the system must be thoroughly flushed. 

Application:
The concentrate is completely miscible with water. For quality reasons, we recommend adding only demineralised water. In its delivery state, the concentrate achieves frost protection > -50 °C without segregating. To ensure corrosion resistance, we recommend not diluting the concentrate to less than 20 % by volume of cooling brine. Heizungsgold Cooling Brine ConcentrateSK is miscible with all antifreeze agents based on monoethylene glycol and is free of nitrite, nitrate, secondary amine, phosphate, borate and silicate. Furthermore, Kühlsolekonzentrat SK only contains corrosion protection agents with water hazard class WGK 1, is non-toxic and is biodegradable. 

Material compatibility:
Materials commonly used in plant and heating construction are not attacked. Polyurethane elastomers, phenol-formaldehyde resins and soft PVC are not resistant. 

Test method and corrosion properties:
We recommend checking the filled cooling brine regularly (approx. annually). You can check the corrosion properties of our cooling brine via the pH value. The pH value should be > 7.5. The measurement is carried out e.g. via pH measuring strips. If the value is lower, the fluid should be replaced or treated with Heizungsgold pH-Fixx. 

Storage:
Store in a cool place and in closed containers.
