Process Technology Aquaculture Products - Setting the Standard
Process Technology has taken heating technology one step further. Our innovative aquaculture heater design proves once again our commitment to a higher standard of excellence. Many heater companies make idealistic statements about quality and performance, but at Process Technology we back our claim with action.
• Innovative Design. We’re the first heater company to design and manufacture electric immersion heaters with aquaculture in mind. Our products include more standard features than the competition, at no additional cost.
• Value. Our new heater design delivers the highest value in the industry. Our innovative technology and assembly techniques enable us to provide products at the most competitive prices in the industry.
• Quality. Our reliability has been acknowledged and tested by the people who set the standards. We are CE-compliant and use UL/CSA components in our products. No other products deliver our combination of performance, reliability and safety.
• Service. We have the largest technical support team in the industry. Each member is experienced, knowledgeable and professional. With worldwide distribution, we are ready to serve you any time or any place.
• Safety. Safety is built-in, not added-on. Our products are the safest available at any price. We offer more models with over-temperature protection as standard than any other manufacturer.

Thermal Overload Protection
Protector I SeriesThe Protector I over temperature control system utilizes a heat sensitive fuse to detect overheat conditions. The fuse, placed inside a thermowell, positioned in contact with the heater sheath, will cut power to the heater in the event of low liquid level.

VOLTAGES AVAILABLE (MOST HEATERS AND CONTROLS)
Voltages are designated in Process Technology model numbers as follows:
| 1=120 volt | 2=240 volt | 3=380 volt | 4=480 volt | 5=415 volt | 6=600 volt | 8=208 volt |
Please specify voltage and single or three phase when ordering. Consult factory for other voltages.
WARNING!
IGNITION SOURCE AND SHOCK HAZARD! ELECTRIC IMMERSION HEATERS WILL IGNITE MANY PLASTIC TANKS SUCH AS POLYPROPYLENE AND POLYETHYLENE, AND SUBJECT PERSONNEL TO SHOCK HAZARD IF NOT PROPERLY INSTALLED AND MAINTAINED.Products listed are designed for service in aquaculture-related (water) applications only, not for use in chemical applications or flammable solutions or solvents.
Determining Heating Requirements for Electric Immersion Heaters
To determine the heating requirement of a tank, first obtain the following information:
1) Total cubic feet of tank. (Multiply the inside dimensions of the tank in feet - length x width x depth.)
2) Total gallons of water. Multiply by 7.48 the cubic feet of the tank occupied by water. (If the water is normally 6" below the top of the tank, allow for this when figuring.)
3) Average ambient (room) temperature at which tank will be used.
4) Temperature level at which water is to be held.
5) Heat-up time desired.Losses due to agitation and ventilation should be considered in calculating total kW requirements. After this information is known, the following calculations can be made:
A x 1.0 x 8.35 x B = _______________
3412 x CD x E = _______________
Add the results of both calculations. The total is the Kilowatt requirement of the tank.
A = Total gallons of solution. One liter = .264 gallons.
B = Difference from ambient temperature and desired water temperature in degrees F.
C = Desired heat-up time (hours).
D = Heat loss of tank. Refer to chart below.
E = Square feet of top of tank. Multiply length x width.

Amp Calculation for Control Selection
For single phase or two wire power supplies to heaters.
AMP RATING PER POLE* = Total capacity (watts) divided by line voltage
Example: 3500 watts divided by 240 volts = 14.58 AmpsFor three phase balanced power supplies (Delta or Wye connections) to heaters using a three-pole contactor.
AMP RATING PER POLE* = Total capacity (watts) divided by (line voltage x 1.73)
Example: 3500 watts divided by (240 amps x 1.73) = 8.43 AmpsContactor sizing:
*Amp rating per pole x 1.25 = contactor rating

This chart provides an easy reference to estimate the kW required to heat a tank. Heat loss from the surface of the water and from the sides of the tank have been taken into account. Find the gallons at the top, move down the chart to the temperature at which you will be heating the water. The number indicated here is the kW required for the heating job. This kW figure assumes a heat-up period of twelve hours; for a six hour heat-up time, simply double the kW figure.
