Principle Of Operation And Safety Features - Cole Parmer FSB-200 Series Instruction Manual

PRINCIPLE OF OPERATION AND SAFETY FEATURES

The equipment, as described in this Instruction Manual, has been designed for use by properly trained
personnel.
It is important that all relevant information relating to the equipment be distributed to employees who may
handle or encounter it. We would stress the importance of standard, common sense rules and adherence
to normal, safety standards and procedures. (For example, any covers or enclosures should only be removed
by trained personnel.) Please ensure that all those involved in the operation of this equipment are
knowledgeable of the design criteria and that it is used in accordance with the instructions and
recommendations contained in this manual. If there is any doubt whatsoever relating to the proper use of
this equipment, please contact your supplier.
The industrial fluidised baths detailed in this manual are designed specifically for "burning off" residue
from plastic machinery tools. However, the IFB baths are also a good choice for many heat treatment,
reactive chemistry and exothermic reaction type of applications. The systems are effective on the full range
of plastics, including polyethylene, polypropylene, PVC, nylon, polyester, polycarbonates, acrylic,
polystyrene and acetyl. In addition, they are effective with rubber, EPR, epoxy resins and acrylic paints. They
provide a safe, dry and fast means of removing all plastic residue with a minimum amount of effort and
physical contact with the tools. The "burning off" operation is controlled at a uniform temperature so that
distortion is avoided. Furthermore, as the fluidised bath is non-abrasive, physical damage to parts is minimal.
Each of these factors extends tool life.
The fluidised bed is housed in a circular container manufactured from 0.075" (14 gauge) stainless steel.
This container is surrounded by electrical heating elements and housed in a square insulated case. The
temperature of the fluidised bed is set and maintained by digital PID temperature controller, which is
governed by the electrical signal from a type "K" (chrome/alumel) thermocouple placed along the fluidised
bath container inner wall. Current to the heating elements is switched on and off by means of solid state
relay actuated by the temperature controller. The controller has a resolution of 1° and can be switched
between °C and °F.
The FSB-200-5I and FSB-200-12I are supplied with an internal contactor that disables power to the heaters
if one of the following conditions occur: thermocouple failure, loss of power to or controller fault and/or
exceeding the factory set high temperature limit of 620°C (1148°F). The controller will flash a message
when one of these conditions has occurred and can be reset for operation once the situation is corrected.
See section OPERATION for more details on the PID temperature controller.
The air supply to the bed must be clean and dry. An air filter and pressure regulator can be supplied as
optional equipment (part number F5915).
