11. Hostile Environment Precautions
The JCB EcoMAX engine has been designed for use in a wide range of conditions. Normal
environments are described as temperate and tropical, and are defined in terms of the
following:
Temperate - Ambient temperatures between -20ºC and +40ºC
Tropical - Ambient temperatures between -20ºC and +46ºC
Normal environment covers operation above sea level, up to and including 3000 metres
elevation.
Special provisions for operation in hostile environments have been made. You can consult
JCB Power Systems Applications department about any application that falls outside what is
considered to be normal environments.
Temperature and altitude affect the engine’s performance so you must consider this when
you pick an engine’s type and rating.
11.1 General Provisions
11.1.1 Cold Climates
Provision has been made for the installation of an engine block heater (mains powered,
screwed into the oil cooler housing on the LHS of the block) for operation in cold climates.
Provision has also been made in the inlet manifold for the installation of a grid heater for
improved cold start.
The engine block heater is rated at 1000 watts.
The grid heater is rated at 1200 watts.
11.1.2 Wading
The engine is capable of wading for intermittent, short durations up to the centre line of the
crankshaft without modification, although you must make sure that the fan can still operate
properly under these conditions. For greater depths or duration consult JCB Power Systems
Applications department.
11.1.3 Operation in Explosive Atmospheres
For operation in explosive atmospheres, such as in mining applications, you may need to fit
spark arrestors, an air-flow limiting valve or both of these devices.
