Oil cooler series МТ-45 is meant for cooling of turbine oil.
The material of heat-exchanging pipes is a tube bundle, in standard design it is made of stainless steel 12Х18Н10Т GOST 5632-72. Depending on the design and operating conditions, the pipe system can be made of 08Х18Н10Т, a copper-nickel alloy MnZh 5-1 and a nickel-silver grade MNZhMts 30.
List of produced oil coolers series МП:

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 all macroclimate areas overland, except the macroclimate area with very frigid climate (general climatic version).
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:
МТ-45, (ТКЛУ.065179.205), ТУ 3113-002-76242415-2015, where:
МТ – series of oil cooler;
45 - cooling surface, m2;
ТКЛУ.065179.205 - designation of main engineering document.
Besides above-listed types of the oil coolers, we design and produce the oil coolers by specification of the customer.
