Did you know ground fault protection is required for every electric immersion heater installation?
May 2, 2024 Ground fault protection is specified as a safety requirement for electric immersion heaters in the NFPA* National Electric Code and in Process Technology’s Getting Started Guide. This safety device monitors the electrical current going to and from the electric heater. When an imbalance is detected, the heater is shut off.
If your circuit breaker does not already include ground fault protection, this device can be added to the temperature control box upon request.
Did you know every tank with electric heaters requires a liquid level controller as a safety device?
April 22, 2024 A liquid level control is listed in the installation instructions as a system requirement for electric immersion heaters. The function of the level control is a low-level shutoff of the electric heaters. This will turn off the heaters before the liquid level drops to the point where the top of the hot zone becomes exposed to air.
While many different types of liquid level controls are available, Process Technology offers two types. The LC-series conductivity-style liquid level control features conducting probes that extend into the liquid to detect the conductivity between the probes. These are best suited for most aqueous and conductive liquids. The ESP-series capacitive-style liquid level control can detect the presence of liquid through the wall of a plastic tank. The ESPs are best suited for detecting deionized water, oils or other non-conductive liquids.
These products can be integrated into a new temperature control box or can be sold separately for field integration.
