100% Quality
PRADO steel panel radiators are specifically designed for the conditions of Russian heating systems.
They are engineered for use with a coolant temperature of up to 120 °C at a working pressure of 1.0 MPa. Each radiator undergoes a pressure test at 1.5 MPa during production.
GOST Standard
PRADO radiators fully comply with GOST 31311 “Heating Devices. General Technical Specifications.”
Laboratory tests confirm that PRADO radiators exceed the recommended GOST standards in many respects. For example, PRADO radiators can withstand a burst pressure of up to 3.5 MPa (35 bar), which is almost 1.5 times higher than the GOST 31311 requirement.
The ISO 9001 international quality management system guarantees the consistently high standard of our products (Certificate of Conformity GOST R ISO 9001-2015 [ISO 9001:2015]).
10-Year Warranty
We are confident in the outstanding quality of our products — which is why we offer one of the longest warranties available.
The warranty period for PRADO steel panel radiators is 10 years from the date of manufacture, provided all requirements for operation, storage, transportation, and installation are met.
The warranty applies only to defects caused by the manufacturer.
The warranty does not cover radiators:
- if the requirements for operation, storage, transportation, or installation have been violated;
- with mechanical damage sustained during operation, storage, transportation, or installation;
- showing signs of internal or external corrosion caused by chemically aggressive substances or misuse;
- contaminated internally with solid particles or harmful liquids;
- deformed due to excessive test or static pressure in the system, freezing, or water hammer.
If a Warranty Event Occurs
If a defect caused by the manufacturer is discovered during the warranty period, the radiator must be replaced by the manufacturer.
To fulfil warranty obligations, the date of manufacture must be clearly visible — it is marked on each radiator on the reverse side of the lower welding seam.
