Hotstart’s largest capacity UL C/US combination heating system designed  for hazardous locations in North America.

The OCLE model (UL C/US listed; Class 1, Div 1, Group D T3 or Class 1 Zone 1 Group IIA T3 depending on configuration) is HOTSTART’s largest capacity combination coolant-oil heating system designed for use in North American hazardous location applications. Its combination of heating power options (up to 36 kW for coolant; up to 12 kW for oil) and pump power give it the capability to handle the largest engine heating applications. Its pre-packaged, plate-mounted configuration allows the heating system to be installed on the skid for operator access and its remote automatic function and customer interface connections simplify integration into an existing control system.

This combination system provides double the service in a single unit. By continuously circulating heated oil throughout the sump as well as heated coolant throughout the block, critical fluids are maintained at the optimal temperatures for immediate startup. When compared to cold starts, engines kept at an optimal temperature produce lower NOx emissions at startup. Engine and oil heating also eliminates the need for extended idling resulting in less overall maintenance.  

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.
