Company Description
Watlow $270 Million sales 2300 employees, OEM heaters: band, nozzle, ceramic fiber heater, cable heater, cartridge heater, film, flexible, multicoil, radiant heater. Watlow thermocouples, RTD, thermistors, PID temperature controllers, alarms
 

Watlow manufactures electric heaters of all types and sizes, power controllers that maximize heater performance, temperature controllers for more precise heat regulation, to sensors that provide the controllers with accurate temperature signals.

Products:



Heaters
We go to extremes in electric heating; meeting temperature requirements to 2300°F (1260°C).

Sensors
Our contact temperature sensors can handle anything from cryogenic -328°F (-200°C) to refractory temperatures of 4200°F (2315°C). Non-contact sensors can sense temperature up to 1000°F (538°C) in 700 milliseconds for tighter process temperature control.

Power Controllers
Our variable time-based power controllers, available to 1000 amps, significantly reduce expansion and contraction of the heating element. This extends heater life and improves process temperature control.


Temperature Controllers
Watlow controllers range from simple ON-OFF, non-indicating devices to modular loop systems that allow 32 independent temperature channels with various sensor inputs. PC-based control software provides on-line trending, data logging, alarm reporting and quick controller setup.

 

Applications:

Life SciencesWatlow Silicone Rubber Heater
Heated, moist oxygen is required in patient respiratory therapy and anesthesia. A Watlow silicone rubber heater, engineered to meet both UL and CSA agency approval, is factory vulcanized to the unique geometry of the humidifier's hot plate. The custom heater shape includes holes for a thermostat, hi-limit control and support framework. The sub-assembly increases heat transfer efficiency and reduces the manufacturer's installation cost.

 

THINBANDŽ HeaterPlastics Processing
The patented THINBANDŽ heater's flexible one-piece design makes installation on plastics molding equipment faster and easier. Processors no longer need to remove other band heaters already in place or purchase more expensive two-piece bands. The new spring-loaded QUICK CLAMP secures the THINBAND heater tightly around the barrel with an easy flip of the thumb.

 

Semiconductors Processing
Watlow designed an aluminium pressure cast-in platen assembly that includes a formed cable heater and cooling tube with a well for the RTD sensor. The precision machined surface maintains temperature uniformity to 400°C (752°F). The JIT assembly enables the equipment manufacturer to reduce lead times and supplier base.

 

Series 733 Multi-Loop Cooking ComputerFoodservice Equipment
The Series 733 multi-loop cooking computer provides menu-driven time and temperature control on convection ovens. The control unit can be programmed to include individual shelf timing, carousel control, door open monitoring and special cooking curves. These features combine to assure consistent, flavorful and safe food cooking in commercial restaurants. The Series 733 is also used in griddle, fryer and steamer applications.


Aerospace SensorsAerospace
Watlow Gordon engineers developed a unique sensor with a wear sleeve design for turbine engine exhaust gas temperature sensing to meet the demanding specifications of the U.S. government. The use of precision machining on the investment cast parts along with electron beam welding enabled the sensor to meet a series of qualifications tests including high velocity vibration combined with extreme temperature gradients, hermeticity and calibration accuracy. In more than ten years there has not been a single failure.
