Industrial Diesel Engines

Industrial diesel engines drive pumps, compressors, generators, welders and construction machines where grid power is not available. Seven Star LLC, an independent supplier in Muscat, supplies Hatz industrial diesel engines and open power units to equipment builders, rental companies and plants in Oman and the GCC.

Types of engine in this category

Hatz B-series and D-series single-cylinder air-cooled engines such as the 1B30 and 1D90 power small pumps, generators and compact machines. They need no coolant or radiator, which simplifies service in hot and dusty conditions. Hatz F-series liquid-cooled engines like the 3F45, also offered as open power units with radiator and controls, serve larger pumps and machines. The H-series, for example the 4H50TIC with common-rail injection and turbocharging, delivers higher power with modern emissions technology in a compact design.

How to select an industrial engine

Define the power and speed required by the driven equipment, plus a margin for ambient temperature and altitude derating, which matters in GCC summer conditions. Choose between air cooling for simplicity and liquid cooling for higher power and lower noise. Check the shaft and flange interface (SAE housings and couplings), start system, fuel and oil consumption, emissions requirements for the market, and the available controls and monitoring. An open power unit saves engineering time where the radiator, fuel tank and controls are needed anyway.
