1,200 KVA DIESEL GENSET FOR BAHÍA BLANCA AIRPORT, ARGENTINA

Bahía Blanca Airport, Argentina, has now installed two backup power gensets - the HIMOINSA HSW 500 and HSW 705 generator sets. Each has been fitted with Scania engine and CRAMACO alternator. Combined, the gensets exceed a standby power of 1200 kVA and were provided by the regional distributor, the Elecsen Group.

Comandante Espora Airport, also known as Bahía Blanca Airport, is a domestic airport in Bahía Blanca, Argentina, which is served by Aerolíneas Argentinas and LADE. Espora is also the main base of the Argentine Naval Aviation, and was given the identifier BACE by the Argentine Navy.

The site need a rugged and reliable backup power system to replace the ageing generators it had previously relied on. The airport authorities turned to a reliable regional distributor, the Elecsen Group, for a solution.

The equipment specified was two backup power gensets in the form of HIMOINSA HSW 500 and HSW 705 generator sets. Each was fitted with Scania engine and CRAMACO alternator. Combined, the gensets exceed a standby power of 1200 kVA.

The SCANIA model DC13-72A (02-14) diesel engine 4 strokes-cycle is based on a robust design with a strength-optimised cylinder block containing wet cylinder liners, which can easily be exchanged. Individual cylinder heads with 4 valves per cylinder promotes reparability and fuel economy.

The engine is fully-equipped with a Scaniadeveloped Engine Management System (EMS) to ensure the control of all aspects related to engine performance. The injection system is based on electronically controlled unit injectors, which provides good fuel economy and a high torque.

The engine can be fitted with many accessories such as air cleaners, PTOs and cooling package, to suit a variety of installations. The HSW 705 generator set is powered by a 4-stroke diesel DC16, 16-litre V8 engine also from SCANIA, with a STAMFORD alternator. This is direct injection, turbocharged and aftercooled engine, a 90º V8 with a coolant-based cooling system (collant capacity 68-litres).

Details of the engine are as follows:

*Compression Ratio: 16,7:1

*Fuel Consumption ESP: 154,98 l/h

*Fuel Consumption 100% PRP: 137,92 l/h

*Fuel Consumption 75 % PRP: 102,36 l/h

*Fuel Consumption 50 % PRP: 68,24 l/h

*Lube oil consumption with full load: 0,2 g/kWh

*Lube Oil Specifications: ACEA E5 or E7. The engine is supplied with 24V electrical system, a water separator filter (visible level), a dry air filter, radiator with pusher fan, radiator water level sensor, an HTW sender, an LOP sender, an electronic governor, hot parts protection and moving parts protection.

The HSW 705 generator set comes with a 4-pole CRAMACO alternator. This has a Star-seriesconnection type and S-1 14”mounting type with Class H insulation. The IP23 alternator enclosure (according IEC-34-5), the exciter system is selfexcited, brushless. The Voltage regulator: is A.V.R. (Electronic) with a Single bearing bracket type and flexible disc coupling system. The Coating type is standard (vacuum impregnation)

The industrial alternators meet the requirements of the relevant parts of the IEC EN 60034 and the relevant section of other international standards such as BS5000, VDE 0530, NEMA MG1-32, IEC34, CSA C22.2-100 and AS1359. These alternators quality assurance to BS EN ISO 9001.

The HSW 705 generator (Open Set version) is built on a a steel chassis and features an emergency stop button, an oil sump extraction kit, with anti-vibration shock absorbers.

The chassis itself has an integrated fuel tank, a fuel level gauge, a fuel tank drain plug, a steel industrial silencer -15db(A) attenuation system. The genset can be delivered with a fuel transfer pump (optional) and a steel residential silencer -35db(A) attenuation (optional).

This set runs on diesel fuel and is fed by a 740-litre fuel tank.

Electric control is provided via a power panel with measurement devices and control unit (according to necessity and configuration).

There is a 4-pole thermal magnetic circuit breaker, a Battery Switch and Adjustable earth leakage protection (time & sensitivity) standard in M5 and AS5, with thermal magnetic protection.

The set is provided with a battery charger (standard on gensets with automatic control panels) and heating resistor (standard on sets with automatic control panels).

There is a battery charger alternator with ground connection and a starter battery/ies installed (cables and bracket included). The system is fitted with a ground connection electrical installation with connection ready for ground spike.
