The ESH horizontal single-throw reciprocating compressor is one of the simplest and most basic of all compressor designs. ESH compressors have unmatched versatility and dependability. The final selection is verified by special computer programs that will calculate the performance, select cylinders, frames and distance pieces, compute the gas and inertia loads and torsional stresses which will be encountered in your service. The complete system is protected by an oil pressure shutdown switch.
Units have a pressure gauge and a crankcase window-type oil level indicator.
Oil filter is automotive cartridge-type for easy replacement. Cylinders for any gas or pressure are available for either lubricated or non-lubricated service. Cylinder materials include cast iron, nodular iron and steel. Main, crankpin and crosshead pin bearings are full-floating free to rotate on the bearing journal and within the bearing housing. Due to the unique design having pressurized oil on both sides of the floating bearings, friction is reduced and wear is distributed evenly on both sides of the bearing.
