Cooling (Optional)
The
The modular construction (unique to our units) allows the tube bundle to be easily removed for periodic cleaning. Additionally, check valves are installed on the water supply and drain lines to prevent water from back flowing into the heat exchanger from a closed drain or into the water supply piping.
The controller automatically regulates cooling by opening and closing the cooling solenoid. This allows the proper amount of cooling water to pass through the tubes of the heat exchanger and out the drain. A water supply of 75 psi (517.1 kPa/5.2 bars) maximum is required for connection to the heat exchanger.
2-6 Safety Devices and Interlocks
This section includes information on safety devices and procedures that are inherent to the portable hot oil tcu. This manual is not intended to supersede or alter safety standards established by the user of this equipment. Instead, the material contained in this section is recommended to supplement these procedures in order to provide a safer working environment.
At the completion of this section, the operator and maintenance personnel will be able to do the following:
•Identify and locate specific safety devices.
•Understand the proper use of the safety devices provided.
•Describe the function of the safety device.
Safety Circuit Standards
Safety circuits used in industrial systems protect the operator and maintenance personnel from dangerous energy. They also provide a means of locking out or isolating the energy for servicing equipment.
Various agencies have contributed to the establishment of safety standards that apply to the design and manufacture of automated equipment. The Occupational Safety and Health Administration (OSHA) and the Joint Industrial council (JIC) are just a few of the organizations that have joined with the plastics industry to develop safety standards.
Every effort has been made to incorporate these standards into the design of the portable hot oil tcu; however, it is the responsibility of the personnel operating and maintaining the equipment to familiarize themselves with the safety procedures and the proper use of any safety devices.
