HOTSTART OSA Oil Engine Heater Front HazLoc
HOTSTART OSA Oil Engine Heater Back HazLoc

HOTSTART’s OSA is an IECEx/ATEX-certified compact oil heating system for use in hazardous locations and is designed to maintain an engine or compressor’s optimal oil viscosity for gas compressor or offshore equipment applications. To improve startability and availability, the OSA continuously circulates heated oil throughout the oil sump or lubrication system, maintaining a uniform and consistent temperature to ensure oil viscosity is at optimal levels for engine or compressor protection.

Continuous lubrication of the compressor frame, bearings and crossheads with heated oil minimizes wear and tear, reducing overall maintenance. The OSA delivers the required flow to achieve pressure permissives for startup, eliminating the need for a separate prelube pump, motor and controller. Designed as a user-friendly, pre-packaged system, the OSA includes all necessary components and features a foot-mounted configuration to reduce overall footprint. Its remote automatic function and customer interface connections enable the OSA to be easily integrated into any control system. 

In oil and gas applications, improving equipment availability and maintaining system readiness are critical factors in reducing expenses and improving the bottom line. In cold climates, HOTSTART heating systems ensure immediate startup on demand even in freezing temperatures. In warm, humid climates, HOTSTART systems maintain equipment above the dew point, eliminating the risk of condensation forming inside the oil sump or pan.

Can be used in hazardous locations.
