CSE Coolant Heating System Hazardous Location
HOTSTART’s CSE (UL C/US listed; Class 1, Div. 2, Group D, T3 or Class 1, Zone 2, Group IIA T3 depending on configuration) is a compact coolant heating system for use in North American hazardous locations and is designed to maintain optimal engine starting temperatures for gas compression or offshore equipment applications. To improve equipment startability and availability, the CSE maintains a consistent and uniform temperature by circulating heated coolant throughout the engine block – eliminating hot spots and preventing overheating at engine shutdown.
When compared to cold engine starts, maintaining optimal temperature during down time lowers NOx emissions at engine startup. Engine heating also eliminates the need for extended idling, reducing overall maintenance expenses. Designed as a user-friendly, pre-packaged system, the CSE includes all necessary components and features a foot-mounted configuration to reduce overall footprint. Its remote automatic function and customer interface connections enable the CSE 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 heads during cool down periods.
Can be used in hazardous locations.
