OKC Series

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

*Note: Sizes OKA-4-6 do not include relief valve. Pressures higher than 90 psi (measured at pump outlet) will result in motor overload conditions. Sizes OKA-8-11 come with a 145 psi relief valve built into the pump.

SC Series

Description

The SC Series cooler design uses a large radial blower wheel assembly which spins slowly to draw air through an oversized 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
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
