INTRODUCTION

In order for generator sets to function as intended in hot climates, users must assess the ambient capability of the model prior to acquisition. The ambient capability, or ambient clearance of a generator set, is defined as the maximum ambient temperature in which the cooling system can operate effectively without causing the generator set to shutdown due to high engine temperature. Site conditions, including the altitude and relative humidity, will cause the ambient capability to vary.
