Hybrid cooling US-version (EK-series)

Product catalog summary

Overview
The document outlines specifications and options for industrial oil/water heat exchangers manufactured in Europe, focusing on high quality and customizable designs.

Features

Oil-side efficiency is enhanced by increased surface area from plates.
Waterside durability is ensured with plain tubes.
Heat dissipation capacity reaches up to 2000 hp.
Flow rates can reach up to 400 gallons per minute.
Water tubes are available in copper, copper-nickel, or stainless steel.
Standard high pressure with a maximum of 500 psi.
Five shell diameters are available.
Removable tube bundle options include U-tubes (UK) and straight tubes (R).

Series and Options

Available series include EK/SC, UK/UKT, and Hybrid Cooling.
An optional integrated bypass valve is available for cold-start conditions to reduce pressure peaks.

Materials and Construction

Available in standard, stainless, and seawater versions.
Shells are made from steel or stainless steel.
End caps are available in cast iron, stainless steel, or nickel-plated cast iron/gunmetal with zinc anode.
Cooling fins are made from aluminum or copper.

Performance Data

Performance varies by unit size and series, based on conditions: water inlet temperature of 77°F, oil outlet temperature of 122°F, and oil viscosity of 30 cSt.

Dimensions

Dimensions are detailed for various unit sizes across EK, SC, and UK/UKT series.

Ordering Information

Ordering code includes connection type, unit size, removable bundle type, water tube material, and sales options.

Cooling Water Connection System Overview

Pass Configurations: Offers 1-pass (not for UK and UKT series), 2-pass, and 4-pass (specific to the 1200+1700 series).
Baffle Distances: Technical data depends on operational conditions; contact UniversalHydraulik for variations. Technical modifications are possible, and users should consult operation manuals and maintenance documentation.

Water Tubes

Small tubes are designated as EK.
Large tubes are designated as SC.
U-tubes are available for on-tank coolers (UK) and in-tank coolers (UKT).

Complete Cooler Specifications

Constructed from stainless steel with optional aluminum fins.
Manufactured in Europe with advanced quality and customizable designs.

Technical Data

Maximum working pressure for standard hydraulic applications: Shell = 500 psi, Tubes = 230 psi.
Operating temperature range: 41 - 203 °F.
Options for higher pressure and temperatures are available upon request.
Caution is advised as incorrect installation can damage the cooler.

Note: Refer to the data sheet for SI-units (metric version).
