Oil coolers series ДЦ

Oil coolers are meant for cooling of stationary power oil transformers, autotransformers and electric reactors of general purpose, with cooling system "ДЦ" , "НДЦ" for installation in hinged and remote cooling systems.

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:

У - for macroclimate areas with moderate and frigid climate.
Т - for macroclimatic areas with both dry and humid tropical climate.

ХЛ - for a macroclimatic region with a cold climate.
1 - for operation in the open air (the impact of a combination of climatic factors characteristic for this macroclimatic region).

 

Reference designation of cooler type by order:

ДЦ-180/2280-У1, (ТКЛУ.065179.201), ТУ 3113-002-76242415-2015, where:

ДЦ – series of oil cooler; 
180 - Heat flow, kW;
2280 – distance between pipe walls, mm;
У - climatic version according to GOST 15150-69;
1 - climatic version according to GOST 15150-69;
ТКЛУ.065179.201 - designation of main engineering document.

Example of product recording by export deliveries to the countries with moderate climate: 

ДЦ-180/2280-У1 эксп., (ТКЛУ.065179.201-05), ТУ 3113-002-76242415-2015.

Example of product recording by export deliveries to the countries with tropical climate:

ДЦ-180/2280-Т1, (ТКЛУ.065179.201-09), ТУ 3113-002-76242415-2015.

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.


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