Hazloc Heaters - Model SRH2 Series -Steam Rig Heater
The SRH2 series of heat-exchanger unit heaters is designed for steam applications on drilling rigs where boiler neglect can lead to freeze-up conditions. During an accidental freeze-up the SafeDeform™ core headers are designed to accommodate ice expansion. The SRH2 Series is designed for pressures up to 150 psig (1034 kPa) in single-pass configurations only. Added benefits include our 18-month heater warranty and our reversible core connection feature that allows you to reverse the configuration of the inlet and outlet connection locations, by rotating the core, to suit your installation. SRH2 heaters meet ASME requirements with a National CRN.
All Hazloc Heaters™ SRH2 models are designed to ASME requirements for steam applications. The six sizes of SRH2 heaters include our SafeDeform™ top and bottom core headers which are designed to deform to the increased volume, due to ice expansion, during freeze-up conditions. This feature allows SRH2 heaters to be frozen several times without critical damage which keeps your safety in mind. With our SafeDeform™ feature, multi-pass core configurations are not available.
