* - amount of air drag is given with no account taken of reserve coefficient Кз-1,15 for the contamination of cooling tubes;
** - this type is meant for the air-cooling by absolute pressure 1,0 kilogram-force/cm2;
*** - limiting temperature by operation with intermediate flow.

Note:
1. Runoff – total content of ammonia, hydrogen sulfides, nitrites etc.
2. Suspensions – fractions of mineral and organic origin (mechanical impurities).
3. For water МВ2, МВ3, МВ4, МВ5 – content of chlorides has not to be more than 2000 mg/l regardless of the total salt content.
Climatic versions and category of placing:
УХЛ - for macroclimate areas with moderate and frigid climate.
О – for all macroclimate areas overland, except the macroclimate area with very frigid climate (general climatic version).
3 – for use in enclosed spaces (contents) with natural ventilation without artificial regulation of climatic conditions.
4 – for use in spaces (contents) with artificial regulation of climatic conditions (in enclosed heated or cooled spaces).

ГО – gas cooler;
375 – heat flow, kW;
5256 – distance between the pipe walls of gas cooler, mm;
Н - cooler version depending on sort of cooling water;
УХЛ – climatic version according to GOST 15150-69;
