Pump
Chandler Engineering recommends that the pump valve body be disassembled, cleaned and
rebuilt by our Service Department. A pump rebuild kit is available from Chandler
Engineering.
Heater
Chandler Engineering recommends that the heater be inspected and tested for insulation
breakdown and voltage leakage, which can lead to arcing on the cylinder wall. This
procedure requires the use of specialized test equipment. Insulation breakdown poses two
potentially hazardous conditions: electrical shock hazard to the operator and pitting of the
cylinder at the point of arcing. Chandler Engineering highly recommends that our Service
Department perform a series of tests on the heater at this time interval.
Thermocouple and Temperature Controller
Our Service Department can perform a calibration procedure using specialized
instrumentation to assure that temperature drift and inaccuracies, as a result of time and
usage, are compensated for, in order to keep your instrument compliant with API specs.
