The ST-5 is built by Stirling Technology of Athens, Ohio USA. This engine operates
with air pressurized to 5 bar, by means of a built in air compressor,
and has been designed for
long periods of stationary use for residential and small-scale
agricultural and industrial purposes. Any application which
requires a long life prime mover and continuous hours of
operation is a good candidate for the ST-5. Recommended uses are
electricity generation, water-pumping and powering of small scale
implements, compressors, etc.
The engine is rated at 5 hp and can run off impure natural gas, crude oil or bio-mass. A small
scale rice milling system could use part of the waste husk as fuel
and small scale milk condensing plants, utilize the heat
from the engine as well as the mechanical power.
By the use of simple heat
exchangers, wast heat can be used for space heating of house,
dairy or greenhouse as well as supplying domestic hot water
needs. At full output, the engine produces over 25kW of
recoverable heat.
