* - 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.

 

Basic standards for water:

Characteristics Sort of water and reference designation
Fresh water Mineralized water Sea water
ПВ МВ1 МВ2 МВ3 МВ4 МВ5 МВ6 МВ7 МВ8
Reference designation of cooler version depending on sort of cooling water
Н М М2 М5, СМ
Salt content
in water, mg/l
0…300 300…1500 1500…3000 3000…5000 5000…15000 >15000
Type of contamination runoff, mg/l ≤1 ≤1
suspensions,
mg/l
≤23 ≤50 ≤25 Abrasive contaminants
≤25

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).

 

 

Reference designation of gas cooler type by order:

ГО-375/5256-Н-УХЛ4, (ТКЛУ.065177.005), ТУ 3385-005-73426865-2008, where:

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;
4 – category of placing according to GOST 15150-69;
ТКЛУ.065177.005 - description of  main design document.

 

Besides above-listed types of the gas coolers we design and produce the gas coolers by specification of the customer.
