KTR Oil Cooler is a high-performance cooler made of aluminium, high-performance coolers for cooling hydraulic, gear, lubricating and motor oils as well as water glycol,have 3 type OAC type and OPC type ,MMC type
Overview of the OAC cooling system
The oil/air coolers type OAC and OPC are compact and high-performance coolers for cooling hydraulic, gear, lubricating and motor oils as well as water glycol. Main applications are hydraulic power packs, machine tools, hydraulic presses, wind power and rail technology as well as iron and steel industry. Besides marine and ATEX versions the coolers are available in combination with thermal or pressure bypass valves.
Applications:
– Construction machines
– Agricultural machines
– Rail technology
– Machine tools
– Hydraulic power packs
– Wind power
– Hydraulic presses
– Iron and steel industry etc.
Structure:
– Cooler core (plate and bar) made of aluminium with industrial laminae in black (RAL 9005)
– Fan cover made of steel in black (RAL 9005) – Fan made of nylon PAG
– Protective grid made of steel in black (RAL 9005)
– Fan 12/24V IP68, 230/400V, 400/690V, IP55
– Fan with hydraulic drive
Marine design:
– Cooler core, frame, fan cover with double-component paint
– Electric motor with special paint and protection class IP56
ATEX design:
– Gas sector: II 2G Ex h IIC T6…T3 Gb X
– Dust sector: II 3D Ex h IIIC T68 °C…110 °C Gb X
– Ambient temperature -40 °C < Ta < +55 °C
– Motor and fan as an adequate
Combined coolers type MMC
The MMC cooler is a high-performance cooler made of aluminium. It combines several cooling circuits, for example for charge air, water and oil in one single system. The design of the cooler is specifi cally suitable for heavy duty applications. The laminas are selected based on thermal and hydraulic parameters. The depth of the cooler cores may vary between 32 mm and 200 mm. The cooler dimensions are specifi cally adapted to the respective mounting space. Here sizes up to 2000 mm are feasible. The selection of the fan is based on the requirements calculated such as mass fl ow, noise generation, speeds, etc. When designing the drive there is the option to select between a direct fan drive, an electric motor adapted to the operating parameters or a hydro motor.
Oil/air cooler / cooling-pumping unit type OPC Cooling systems
The OPC oil cooler unit is a system specifi cally developed for cooling in the bypass fl ow as an independent unit. The unit consists of a cooler, fan, electric motor, pump and may be supplemented by a fi lter on request of the customer.
Applications:
– Machine tools
– Elevators
– Test benches
– Add-on coolers
– Bypass flow cooling
Structure:
