Use of the Gen II or Compact Y‐Cylinder Heater with a BSGS eV /
BULKGUARD eV Module
Introduction
The GEN II and Compact Controller Y-Cylinder Heater Systems are designed to regulate the heat
energy input into a fixed volume, horizontally mounted cylinder containing a liquefied gas product for
increased product flow. The system contains three main assemblies which include:
Control System (Figure L-1)
Heating Blanket (Figure L-2)
Insulation Cover (Figure L-3)
After the cylinder and shipping skid are in the desired position to facilitate connection to the supply
piping, the heater blanket and insulation cover are attached to the cylinder. The system is also designed
to maximize commonality of control components with the AP11 based BSGS eV / BULKGUARD eV.
The resistive heater element, with integral temperature measurement elements, is designed to be easily
removable from the gas cylinder without the use of specialized tools. The Compact Heater Controller
heater blanket is hard wired to the control system through the use of cable assemblies. The cable
assembly is 25 feet long for easy disconnection and connection of the heating blankets. The Gen II
Heater Controller design is similar, with the exception of a thermocouple disconnect assembly and
power disconnect assembly at the end of the 25 foot long cables. Power and thermocouple wiring from
the disconnect boxes to the heater controller is field supplied and installed allowing the Gen II heater
controller to be remotely located.
