Tepro-P heat transfer fluids are liquids based on propylene glycol with freezing temperature below 00С.
Tepro-KP concentrate is the concentrated fluid based on propylene glycol, designed to produce Tepro-P working fluids with different freezing temperatures by diluting it with demineralised / distilled water.

According to specifications, heat transfer fluids are designed to be used in heat exchange equipment in various industries, including food processing and pharmaceutical industries (propylene glycol and all used additives are food additives). Thus, Tepro-P heat transfer fluids can be used in air conditioning systems, commercial refrigeration systems, chilling and freezing equipment, heating systems with any types of boilers (other than the electrode boilers), heat pumps, ice arenas and other areas.

WARNING! Tepro-P heat transfer fluids can not be used in the electrode boilers!


Composition: propylene glycol, distilled water, corrosion inhibitors, antifoamers, dye.

Does not contain glycerin and other components that increase viscosity of the product!

Package of corrosion inhibitors effectively protect ferrous and non-ferrous metals from corrosion and sealing parts from deformation.

Tepro-P heat transfer fluids are ready for use. Do not dilute with water!
Before filling the system, Tepro-KP concentrate must be diluted with demineralised/distilled water in accordance with the following table:

Dilution ratio Tepro-KP : water

60 : 40

- 40

58 : 42

54 : 46


49 : 51


45 : 55


Prevent mixing with foreign substances! Do not mix with heat transfer fluids of other manufacturers!
It is not recommended for using in systems with zinc-coated pipes.
Due to the high fluidity of heat transfer fluids(relative to water) pay special attention to the quality of installation.

Heat transfer fluids must be operated under normal conditions

  • Before filling the system with the fluid, wash, clean the system and make sure it is waterproof;
  • Avoid boiling and freezing of the heat transfer fluid;
  • If it is necessary to add the heat transfer fluid, use only heat transfer fluid of the same model.

WARNING! Content of the operated heat transfer fluids may change in case of failure to comply with the above mentioned measures, as well as in time!


Due to high water content, Tepro-P heat transfer fluids are non-flammable and explosion-proof. Tepro-KP concentrate is flammable. In case of fire, use water, mechanical foam, sand, fire extinguishers for fire extinguishing.
Tepro-P heat transfer fluids are based on propylene glycol, which is included in the List of permitted food additives approved by the Resolution of the Cabinet of Ministers of Ukraine on 04.01.1999 No.12, under code E1520.

Tepro heat transfer fluids, produces on the basis of propylene glycol, have safety and health conclusions with permits for use in food processing and pharmaceutical industries.

Notwithstanding the abovementioned, propylene glycol is a moderately hazardous substance. Maximum acceptable concentration (MAC) of propylene glycol vapour in the air is 7 mg/m3.
Do not swallow the heat transfer fluid!
Use only in technical systems strictly in accordance with the purpose!


General measures: Provide comfortable position, warmth, rest, access to fresh air, and conditions for unhampered breathing.
After contact with skin and mucous, rinse thoroughly with plenty of warm running water to completely remove the product.
If swallowed: Clean the mouth of residues of the product, rinse the mouth with water, provide abundance of water, give saline purgative. Consult a doctor.


Provide good ventilation of the premises.
Take measures against further leak, fence the place, collect spillage using rags, sawdust, suitable absorbing material and send it for disposal.
If the spilled heat transfer fluid is washed with water, send the water to the wastewater treatment unit.
Avoid spilling to water and soil.


Heat transfer fluids must be transported in sealed containers.
Heat transfer fluids must be stored in tightly sealed containers in well-ventilated warehouses and outdoor areas, protected from direct sunlight.
Guaranteed shelf life is 5 years from the date of manufacture.


Service life of the heat transfer fluid depends on its operation regime.
To maximize the service life of the heat transfer fluid, it is recommended to strictly adhere to the rules of operation set forth in Application section, and regularly monitor the condition of the heat transfer fluid:

  • In case of an emergency;
  • Once a year if there are no emergencies.

In many cases the heat transfer fluid, parameters of which for whatever reasons no longer comply with the standards, can be corrected to the normal state.
In case when correcting of the heat transfer fluid is not possible, the heat transfer fluid is sent to specialized organizations for disposal according to DsanPІN
