Oil coolers series МБ

Oil coolers series МБ are meant for lubrication systems and control systems of steam and gas turbines.

Oil coolers are manufactured in climatic versions of УХЛ and O, the category of placing is 3 or 4 according to GOST 15150-69.

Technical characteristics, overall and mounting dimensions of oil coolers are agreed by order.

Basic standarts of 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:

Runoff – total content of ammonia, hydrogen sulfides, nitrites etc.
Suspensions – fractions of mineral and organic origin (mechanical impurities).
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.
Т - for macroclimatic areas with both dry and humid tropical climate.
4 - for use in spaces (contents) with artificial regulation of climatic conditions (in enclosed heated or cooled spaces).

Reference designation of cooler type by order:

МБ-20-30, (ТКЛУ.065179.205), ТУ 3113-002-76242415-2015, (when cooling by fresh water)

МБМ-20-30, (ТКЛУ.065179.205), ТУ 3113-002-76242415-2015, (when cooling by sea water)

 

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