Process Tech Heaters, 230V, 3-Phase
Heavy-duty, UL-listed electric heaters can handle almost any immersion water heater need through a wide selection of styles, materials, sizes and controls. These industrial type heaters are perfect for automatic "set it and leave it" applications. Use our heater sizing guide (Tech Talk 74) to select the heater size in watts. Select the style you need and then consult the heater/controller compatability chart.
Choose type 316 stainless steel for freshwater applications and titanium for saltwater. Titanium is slightly more expensive, but it offers the utmost in saltwater corrosion resistance.
The "L" style locates the hot zone along the bottom of your tank. The straight style is easily positioned on the side of the tank. Never allow the water level to drop below the hot zone dimension shown, as heater failure and/or fire could occur (also, keep the hot zone clean of scale buildup). Over-temperature protection devices with Protector 1 are "one shot" devices located on the heater and must be replaced when blown, so keep a spare on hand. Over-temperature protection devices with Protection 2 are "quickly" resettable.
Protector 2 is available on all models (call to order). The price is the same. Your controller and heater need to be the same, either with Protector 1 or Protector 2. Be sure to order a compatible controller (unit will not operate without Process Tech controller with Protector 1 or Protector 2).
Electrical cable is not included with these heavy-duty heaters. An electrician will need to wire the heater to the controller and the controller to the power supply.
In addition to the sizes shown, custom sizes can be ordered at additional cost. Almost every heater is available in 460V at the same price as 230V. Call for quantity pricing. All heaters and components are guaranteed for one year. Due to the custom nature of our heaters, allow a minimum of one week for production. Made in USA.
Ships directly from the manufacturer.
Even though these heaters are very reliable, we advise using two or three small heaters rather than one large heater that, in the event of a failure, could allow severe temperature drops. Replacement fuses, sensors, heaters and controllers are from Process Tech.
Protector 1 and 2 Manual
We highly recommend using protective devices with all 3-phase equipment. Motor starters, phase monitors and phase protectors are not included in the sale and should be sourced locally. Failure to install protective devices will void most warranties. We also recommend that a certified electrician perform the installation.
