BYPASS SERIES GLOBAL STANDARD COOLER HY
HY OIL-To-AIR COOLING SYSTEMS WITH integrated Bypass and HYDRAULIC MOTOR Product Information AKG-Line is a standard line of products from the market leader in high performance aluminium cooling systems. AKG is best known for its world-wide presence, German engineering and extremely reliable product quality on the one hand and very competitive prices on the other hand. The AKG-Line Bypass Series consists of different models for mobile and stationary applications. It is available through our global specialist dealer network. This line of products embraces all-purpose complete cooling systems that comply with European or American Standards, is suited for normal or rugged environmental operating conditions and powered by AC- (AY), DC- (DY) or hydraulic-motor-driven (HY) fans. All of AKG s solutions have been developed with stateof-the-art technology, produced in compliance with the highest quality standards and are comprehensively tested in the company s own research and test facility. Features of the HY series - High-Performance cooling assembly - Hydraulic motor powered fan - Avoiding overstraining at cold start conditions and high oil flows BENEFITS - Largest and most comprehensive series of mobile hydraulic coolers - Highly flexible, complete ready-to-use cooling packages - Compact design because of integration of bypass - Faster approach of operating temperature - Compact and robust design, field-tested during many years of use in rugged real life conditions - Best heat transfer results per given cooler size due to comprehensive research and development - Highest quality due to professional engineering and in-house manufacturing - Available from stock or at short notice - As a standard equipped with AKG s double-life hollow sections designed to increase cooler life span Operating mode of integrated bypass Especially with high oil flows or at cold start conditions (low oil temperatures and high oil viscosities) high pressures can occur in the cooler core. In this case part of the volume flow is bypassing the cooler core through the integrated valve. Like this a sufficient volume flow can be assured for the cooler and lubrication oil circuit - also with high pressure drops. Overstraining of the cooler core will be avoided effectively. - The heat is transferred from the hot medium to the cooling ambient air - Coolers can be universally used with hydraulic oil, transmission oil, engine oil and lubricating oil - For the cooling of mineral oil, synthetic oil, biological oil as well as HFA, HFB, HFC and HFD liquids (other media on request) - Can be exposed to operating pressures of up to 17 bar and operating temperatures of up to 120 C - Standard design with 2 bar opening pressure bypass valve (other pressures on request) The installation of an external bypass is not necessary reducing costs and mounting space.
