DXTZ Series Marine Motor-driven Air Cooler
The cooler, through vacuum brazing process, is driving by high-efficiency marine motor.
And the plate and shell are treated with special anti-salt fog treatment,
so that the cooler can meet the requirements of salt spray prevention and wave impact resistance,
also can adapt to long-term outdoor operation in harsh environment.
· Temperature controller,filter and bypass circuit can be selected.
· A variety of pressure protection forms can be selected.
· The oil inlet and outlet of the cooler are standard G thread, also can be customized or connected with SAE flange as required.

| Note： * Cooling capacity: cooling power at △T=40℃. ** The noise value is measured at a distance of 1m from the cooler, which is only for reference. Because it is affected by the surrounding environment, medium viscosity and reflection. *** This table only takes AC380V-50HZ as an example. **** Motor grade: Energy consumption grade YE2, protection grade IP55, insulation grade F.

DONGXU air-cooled coolers are divided into indirect, fixed and suspended types.
It also has many features, its simple structure, small size, small weight and ease of use are all its advantages.
Air-cooled oil cooler (referred to as air cooler) is an aluminum alloy plate-fin heat exchanger with air as the cooling source. The same volume is larger than the traditional heat exchange area, the heat transfer efficiency is high, and the air is used as the medium for heat exchange.
Compared with the water-cooled radiator, it is not only easy to install and maintain, but also can avoid the oil-water mixing caused by the copper pipe burst, which will cause serious damage to the system.
Secondly, for equipment (such as construction machinery) that needs to change the working location, there is no need to consider the supply of water sources, and there is no disassembly and reconstruction of the water circulation system. It is an environmentally friendly product that is increasingly widely used.
DONGXU is one of the most credible special motor hydraulic oil cooler manufacturers and suppliers in China.
Welcome to buy special motor hydraulic oil cooler with reliable performance with our professional factory.
