Strip Heaters ~ Watlow >> Chromalox

Sords Electric can provide Strip heaters.

Strip Heaters are used to heat a surface and should be clamped or banded to the surface.
The most commoN strips are 1.5 inches wide and up to about 36 inches in length and have offset terminals, meaning two terminals at one end but offset to each other. Strip heater are usually 120 volts or 240 volts.  Wattages are from 150 to 2250.

Below is a Chromalox to Watlow Cross reference
These strip heaters have OFFSET terminals at one end, hence the OT for Offset Terminals.

Convectronics Air Heaters

Convectronics and Sords Electric

Convectronics manufactures first class heaters, temperature sensors and precise controls. We offer a wide variety of industry standards available for “Just In-Time Delivery” and manufacturing capabilities which cover a broad spectrum of customized products for most applications. With over twenty years of knowledge and experience in temperature sensing and controls, Convectronics is able to offer you elite technical support and service along with the highest quality products. Our Technical Staff is waiting to assist you with all your design and application needs. 

CONVECTRONICS QUARTZ AIR HEATER

When you need a heat source, Convectronics’ products are designed to meet and exceed all expectations. Convectronics Air Heaters use state of the art materials and can be found throughout the world in countless industries.

• Temperature up to 1500°F
• Clean electric heat without the flame
• Compact size with rapid heat-up and cool-down
• Controllable by varying voltage, flow rate or
  temperature controls
• Excellent repeatability
• Directable heat
• Easy installation

• Repeatable • Adaptable • Stable • Reliable
• Precise • Accurate • Controllable
• Clean • Sturdy • Responsive
• Economical • Dependable
• Compact • Efficient
• Powerful

Air heaters work by continuously passing air/fluid over a heated element. This air/fluid is heated and then discharged from the heater, giving a consistent supply of reliable heat. The material being heated can either be inert gas, compressed air or air from a regenerative blower. Unfiltered gas that may contain dirt, grease, oil, oil vapors, corrosive or reactive gases along with volatile or combustible gases should never be used. It should be noted that material should always be flowing over the element before and even after power is supplied to the heater or the result may be overheating of the element and reduced life.

Optimum heater life is achieved by operating the
element within its specified performance characteristics and monitoring the element temperature. Elements operating outside their recommended limits will glow beyond the midsection of the heated length.

Best operating results will be obtained by using a thermocouple feedback temperature control and phase angle power control. When using only a voltage control extra caution should be taken. Apply voltage to the heater until the desired air temperature is obtained.

Air Heater Selection:

When selecting a heater you must first determine the power required to heat air. This can be done by using the following formula:  

Power (Kilowatts) = [(SCFM x Delta T) / 3000] x 1.2

SCFM   = Standard cubic feet per minute
Delta T = Temperature (exit) - Temperature (inlet)
                  In Degrees Fahrenheit

When selecting heaters it is important that a good control system is also selected. A good control system is critical for long heater life. Convectronics offers open-loop (manual) controls, closed-loop (feedback) controls and all the components necessary to run Convectroncs heaters.

The Convectronics Power Control Module Part # 006-10062 offers infinitely variable phase control when used with resistive loads up to 25 amps. The solid state circuitry provides modified transient suppression, exceptional stability and life. An external potentiometer/switch (dial plate and knob included) is used to control output voltage. A trimming potentiometer is mounted on top of the module to adjust turn on voltage level. This device should be installed in a circuit fused at 120% rated load or 30 amps maximum.

These controls provide phase angle proportional control of our fast responding heaters. They are available in single and three-phase 240-volt configurations. Each unit comes complete with I²T Rectifier Fuses and a Voltage Limiting Adjustment.

The controls can be operated manually with the addition of the optional Manual Voltage Control, which allows one to vary voltage from zero to full voltage.

The S.C.R power control can be used with a 4-20mA temperature controller for closed loop operation.
