Frequently Asked Questions
- Q: What are the power requirements for the unit?
A: The unit requires three phases of 50 and 60 cycles of nominal voltages with the control circuit operating on 115 volts single phase.
- Q: I’m wondering how to establish the watt intensity of the heater that I will be using.
A: In order to give you a more accurate answer, I would need to know the specifics of the heating process. Available options are 4.5kW, 9kW, 12kW, 18kW, or 24kW.
- Q: Can I know the electric immersion heater materials?
A: A standard immersion heater utilizes copper sheath, however, incoloy and stainless steel can be provided as alternative materials upon request.
- Q: What are the safety defining features of the unit?
A: The device consists of a safety thermostat so that the device does not suffer from thermal runaway and a pressure safety switch is implemented so that the device does not becomes functional while dry.
- Q: Considering pump operation, how do I avoid cavitation?
A: If a water supply pressure of 25 psi or greater is maintained the pump will not cavitate however it should be noted that water supply pressures greater than 75 psi should not be used.
- Q: What is the mechanical engineering point of view in regards to the system employed for cooling?
A: The system does some resounding wonders as it opens and closes the solenoid valve in order to reach and maintain the desired temperature with the aid of the temperature controller.
- Q: I want to know whether the unit can be used and monitored remotely.
A: Yes, as per the options selected for the controller, it can be operated and monitored remotely along with the process control elements.
