A flameless heater for operator\s cab having automatic heat control. A hydraulic pump provides pressurized fluid which flows through a fluid restrictive orifice to produce thermal energy and raise fluid temperature as a result of a drop in hydraulic pressure. The heated fluid flows through a heat exchanger where a fan blows air over the exchanger to provide hot air for the operator\s cab. A spool valve connected in parallel with the orifice bypasses fluid around the orifice to limit the rise in fluid temperature. A temperature sensor selectively opens an...
A flameless heating system for the opertor\s cab of a machine having at least one hydraulically-actuated device powered by a source of pressurized hydraulic fluid connected with said device by a supply line; said system comprising: a hydraulic reservoir mounted on said machine; a hydraulic motor interposed in and in constant communication with said supply line; a hydraulic pump mechanically connected to and driven by said motor and having an intake conduit connecting said pump to said reservoir; a heat exchanger mounted adjacent said cab; an output condu...
