HM Metal-Housed Beaker Heating Mantles with Built-in Controllers - BriskHeat

BriskHeat HM Metal-Housed Heating Mantles are fiberglass insulated heaters for laboratory and pilot laboratory applications. They are used to heat a variety of round bottom shaped vessels, to either increase temperature or keep media at a constant process temperature. All heating mantles are manufactured to high quality standards of craftsmanship.

The exterior of the HM Metal-Housed Heating Mantle with Built-in Controller is a plastic-coated metal casing, with a pre-molded fiberglass liner to hold the round-bottom flasks. The heating element consists of a chrome-nickel alloy resistance wire which is electrically insulated using a crocheted high-temperature yarn. The adapted shape ensures an even heat transition to the glass flask, and a layer of fiberglass insulation under the heating element reduces heat dissipation to increase efficiency.

  • Flexible fiberglass heating element for uniform heat
  • Durable plastic-coated chemical resistant metal housing
  • Thermally insulated and grounded for safety
  • Round bottom flasks up to 20 liters (20,000ml)
  • Includes predrilled threaded hole on rear for clamp accessory
  • Built-in 1 or 2 zone heating option
  • 120V or 240V
  • 5-foot (1.5m) power cord
    • 120V models include 3-prong stright-blade plug
    • 240V bare wire ends
  • For operating temperatures up to 450°C (842°F)

PRIOR TO INSTALLATION

  1. Check for suspected damage to the heater like rips, punctures, etc.
  2. Confirm voltage / wattage rating of heater is appropriate for power supply device or temperature controller. The heater is designed to work at a specific voltage to heat properly. Failure to operate the heater at the specified rating could result in overheating of the heating element, the surface being over-heated, or personal injury. Also note lower-than-rated voltage will result in under-heating.

To Avoid Electrical Shock, Always:

  • Use an electrical outlet that operates with a fuse or a circuit breaker and a ground fault circuit interrupt (GFCI).
  • Disconnect the mantle from the power supply prior to maintenance and servicing.

To Avoid Personal Injury:

  • Do not use in the presence of flammable or combustible materials. Fire or explosion may result. This device contains components which may ignite such materials.
  • Do not operate in damp or wet locations.
  • Refer servicing to qualified personnel only.
  • Flasks and vessels should be handled with care. Appropriate safety clothing, glasses, gloves, and coats should be worn when operating all heating mantles.

To Avoid Damage:

  • Never plug HM-MH models directly into a power source. Your heating mantle MUST be operated with a temperature controller and with an appropriate size flask, filled with fluid.
  • Never operate heating mantle without fluid within the flask.
  • Fluid should not be allowed to come in contact with the cavity of the heating mantle.
  • Never operate the mantle at temperatures above maximum exposure temperature .

INSTALLATION
Your heating mantle is a fiberglass-insulated heater designed for heating laboratory vessels. The mantles are specifically designed for glass flasks, however, with appropriate temperature control and product type, metal or plastic flasks can be used. Only use round bottom flasks of the size corresponding to the mantle size.

  1. Install heating mantle around properly sized flasks.
  2. For proper temperature control, secure the thermocouple, RTD, or other sensing device vertically along the lead wire seam of the blanket with one strip of adhesive tape so that it is sandwiched firmly in-between the heater and glass flask.
  3. Sensor must be in close proximity to the heater to prevent overheating.
  4. Sensor should be connected in accordance with instructions provided with temperature controller.
  5. Ensure heater is in contact with the surface to be heated. The heater must fit tightly around the glass flask. Minimal air gaps between the heater and the flask provide the best thermal transfer of heat to the flask and extend heater life.
  6. Once the mantle has been properly installed:
  7. 120VAC: Plug the heater into an acceptable temperature controller. Use a variable transformer, manual control, or automatic controller to prevent overheating.

Note: Due to their overall size, the heating mantle sizes 50ml and 100ml are only designed with one heating zone. They are put into operation by means of an MIN/MAX switch. Maximum heating element temperature for series HM-MC: 842°F (450°C).

  1. Connect the heater to an appropriate power supply.
  2. Heating Mantle can be switched on and off by using the green ON/OFF switch.
  3. With the MIN/MAX switch the heating zones can be switched (See Figure 2)
  4. The built-in power controller is used for the continuous adjustment of the power input.
  5. The yellow indicator light indicates the heating power is on.
  6. In case of the liquid level dropping during operation, adjust/switch heating zones accordingly.

BAKE-OUT PROCEDURE FOR NEW HEATING MANTLES
On the initial heat-up of the mantles, a slight odor may be detected and some discoloration will
occur in the cavity area. The discoloration of the cavity area has no effect on the operation of the
mantle. If the heated vessel becomes discolored, it can be cleaned with water. To bake-out your
mantle prior to use, connect the mantle to your temperature controller and fill a flask
corresponding to the size of the mantle half full of water. Place the flask in the mantle cavity and
allow the water to come to a boil and continue boiling for approximately 15 minutes. The mantle
can be operated at full rated voltage during bake-out.
