Immersion Heaters

PID Controllers

kksolution Ceramic Band Heaters were developed to meet industrial requirements for high temperature long lasting heaters. They are ideally suited to comply with today’s new resins, which calls for ever-increasing process temperatures.

An additional advantage of the Ceramic Band Heaters is that they transfer heat through conduction and radiation. This makes their tightness on barrels less critical; thus they are less prone to thermal expansion problems.

Theoretically, there are no restrictions on the diameter that ceramic band heaters can attain; however, because these heaters utilize ceramic tiles that are available only in specific lengths, the width of these heaters falls within a certain incremental range of sizes.

PRODUCT INFO

kksolution introduces state of art, truly universal, powerful PID controller with inhouse design. The PID2020 series is developed with state of art microcontroller. The robust hardware and software makes the controller very useful in noisy industrial environment. The PID2020 finds applications in Industrial Ovens, Muffle Furnaces, B.O.D. Incubators, Humidity Chambers, Environmental Chambers, Sterlizers, Blood Bank Equipments, Constant Temperature Baths, Packaging, Plastic Moulding, Thyristors Heat Controllers, Motor Controllers, Controlled Melting, Valve Control…etc.

Features

  • Initializing the controller integral to a desired value
  • Increasing the setpoint in a suitable ramp
  • Disabling the integral function until the PV has entered the controllable region
  • Limiting the time period over which the integral error is calculated
  • Preventing the integral term from accumulating above or below pre-determined bounds
