Market Speak - Are Hydraulic Fan Drives for You?Picture: Glendinning ProPilot

Hydraulic fan drives have caught on as the most effective way to cool diesel engines. A diesel's operating efficiency (fuel consumption) and emissions output are closely related to operating temperature. A diesel consumes the least amount of fuel per horsepower produced within a relatively narrow band of temperatures. Likewise, a diesel puts out the least amount of emissions per horsepower within a similar temperature range. So operating the engine within the narrow range of temperatures where the two overlap derives the most power from a diesel engine while minimizing fuel consumption and emissions.

Traditional, belt-driven fans produce air flow that is dependent upon engine speed, not cooling demand. This means belt-driven fans are always using engine HP and could be wasting energy. Maximum power is lost when the engine (fan) runs at high speed, even though little cooling may be needed. Moreover, an idling engine may need very little air flow, but, again, the fan continues to run at an unnecessarily high speed. Unlike traditional systems, hydraulic fan drives operate with variable speed. This means air flow through the radiator can be closely matched to the cooling requirements of the engine.

Custom Solutions - ProPilotPicture: Glendinning ProPilot

The EVC caught the attention of John Glendinning, President of Glendinning Products, LLC. He first approached HCT with the need to control a Sun Hydraulics RBAPXAN224 valve in addition to needing J1939 communication. The standard EVC is a configurable open-loop or closed loop single and dual coil controller with J1939 communication. John received an EVC controller and had it running on a test network within a few short weeks by ordering the EVC Qwick Pick development kit through their local HCT distributor. “My programmer found it very easy to configure, so this looks like a winner for both of us.” - John Glendinning.

The project wasn’t over yet. John requested a custom J1939 communication rate and private label. Working with our engineering team, from time of order to delivery, John received a custom EVC controller within 30 business days.

Glendinning Products utilizes the EVC in a very unique way. “Where we are using your product is with our ‘ProPilot’ joystick control. We are using your product to interface between the joystick and hydraulic bow thruster controllers.” said Glendinning. The ProPilot is an optional accessory that can be added to most existing and any new Glendinning control systems on boats with inboard propulsion and bow/stern thrusters. The ProPilot control offers the boater an extremely simple and intuitive means of controlling the complete propulsion system of their boat using a single joystick interface. Maneuvering and docking is made easy using the single joystick control. By simply moving or rotating the ProPilot joystick, the engine and thrusters will activate to effortlessly move the boat in the required direction.

Hydraulic Fan Drives - Norwegian State RailwaysPicture: Duewag NSB Type 92 Locomotive

By Gary Gotting is V.P. sales & marketing with High Country Tek, Inc.

Hydraulic fan drives are widely used with diesel engines to reduce fuel consumption, emissions, and noise. Despite the additional cost to OEMs, the high return on investment on hydraulic fan drives has been a major reason for their continuing growth.

However, hydraulic fans drives are also being used in train locomotives — specifically, PMC Servi AS, of Norway, which won a contract to upgrade trains used on Norwegian State Railways. Design engineers decided to retain the existing hydraulic cooling and take advantage of several major benefits, including fully independent fan speed control (fan speed can exceed engine speed) and significant fuel savings due to more efficient use of available engine power.

A 'Cool' Bus StoryCentral Ohio Transit Authority

By Gary Gotting is V.P. sales & marketing with High Country Tek, Inc.

By now, we are all very familiar with many benefits that come virtually free when using a hydraulic fan cooling system — managed engine loading, lower fuel consumption, less fan noise, lower maintenance costs and fewer trips to the repair depot — the value proposition list goes on and the ROI is a dead certainty, not to mention the feel good factor of an environmental plus with every installation.

About five years ago, Central Ohio Transit Authority’s (COTA) vehicle maintenance department at McKinley Avenue, Columbus, had overheating system issues on an in-service rear-engined passenger bus caused by the under performing cooling system. Michael Suchecki, the heavy repair supervisor, called Ed Spahr from Sunsource Hydraulic Service & Repair in Hillard, Ohio, and together they began investigating the problem.

It was determined that even with a standard pressure wash down schedule in place, the side-mounted radiator was getting clogged with road debris and loose dirt, enough of which was sticking to the core, reducing the elements efficiency and useful cooling area. Spahr recognized the symptoms and knew the solution that was needed was an upgrade to a reversible hydraulic fan drive.

Refuse Truck Side LoaderSide Loader

The Application – Position Management of Trash Can Pickup Arm.

The Challenge – Increase productivity, reduce maintenance cost & frequency and reduced noise.

Our client had encountered low operators efficiency due to the lack of training and/or lack of manual dexterity. In addition, high hydraulic component failure rates were encountered due to the arm being raised and lowered at high rates of speed. Engine noise was excessive when the arm was being raised and lowered.

The Approach - The method of control used prior to the introduction of the DVC system was a joystick control by the operator. The problems associated with this method of control were numerous, including operator proficiency in the operation of the joystick. Additionally, there were no safety features to stop the arm if it encountered resistance and the speed with which the operator moved the arm.

The Solution – Install a DVC10 Master Control Module to control arm positioning, bin pickup, dump and return of bin to original position and engine RPM.
