OKC Series
Description
These coolers use a combination of high performance cooling elements and high capacity, compact AC Electric powered fans to give long trouble free operation in hydraulic applications.
The compact design allows the coolers to fit most equipment and provide the highest cooling performance in heat dissipation while minimizing space required.
Features
- Cooling Range: Up to 23 HP
- AC Motors in 230/460 Volt 50/60 Hz
- Hydraulic Pressure: 230 psi Dynamic
OK Series
Description
The OK Series cooler design uses a axial fan assembly which draws air through the cooler. This combination offers excellent cooling capacity with low noise.
Features
- High efficient plate and fin style heat exchangers
- Externally mounted heat exchangers for easy maintenance and cleaning
- Modular pump and filter options for a plug and play fluid conditioning system
- Available with HYDAC MF and LPF series filters
- Accessories Include: Thermostats (adjustable and fixed), Integrated Thermostatic Bypass Valves, and Bypass Valves
- Up to 100 HP cooling capacity
- Packaged systems with pump flows ranging from 8.45 gpm to 47.5 gpm
- Maximum flows (without pump) up to 90 gpm

- Externally mounted heat exchangers for easy maintenance and cleaning
- Modular pump and filter options for a plug and play fluid conditioning system
- Available with HYDAC MF and LPF series filters
- Accessories Include: Thermostats (adjustable and fixed), Integrated Thermostatic Bypass Valves, and Bypass Valves
- Down to 64 dBa noise level
- Up to 16 HP cooling capacity
- Warm air is directed up and away from work area
- Packaged systems with pump flows ranging from 3.1 gpm to 18.5 gpm
- Maximum flows (w/o pump) up to 42 gpm
