Heater Insulation Material

Standard heat or heater tapes are made from fine gage stranded resistance wires that are double insulated with braided fiberglass and knitted into flat tapes for maximum flexibility. A heavy insulated heat tape is made by taking a standard tape and braiding it between layers of fiberglass yarn. Wide tapes are made from two or more standard tape heaters that are sewn between two layers of fiberglass cloth.

SRT, FGH, FWH, STH, or SWH series tape are good for direct contact on a conductive surface. Never use FGS or SST series tape on a conductive surface.

Heating Elements: 36-40 gage resistance wire.
Lead Wires: Emerge from opposite ends into separate sides of an integrally molded separable plug
Heating Element Insulation: Double-braided fiberglass
Dielectric Strength: In excess of 2000 V

Fire and electrical shock may result if products are used improperly or installed or used by non-qualified personnel. See inside back cover for additional warnings.

Rated 5 out of 5 by from Great Features I bought it a month ago and it worked better than I expected!

Rated 5 out of 5 by from Highly Versatile I've used this to heat various items of various shapes. The split AC plug is genius!

Rated 5 out of 5 by from High quality heater tape This is a high quality heater tape that does exactly as specified. At 115 VAC & 1.7 Amperes it delivers the expected 195 watts. The only problem I had was finding a safe way to keep the tape securely wrapped around a spherical distillation flask.

Rated 5 out of 5 by from Fiber glass heat tapes Good product that has both ends connections or on one end. Come sub different lengths and still able to maintain the temperature needed. Very flexible now and easy to install. Prices are reasonable too.

Rated 5 out of 5 by from Heater Tape Performs as expected from item description in the omega catalogue

Rated 3 out of 5 by from Plug style is disappointing The reason I give 3 stars is that I’ve purchased other heating tapes from Omega in the past, and what I did not like about these is the plug halves being at different ends. It causes problems in reaching the controller box and gets in the way when wrapping it around my sample cylinders. (I like to stretch out the tape from one end to the other to maximize distance covered.) The tapes themselves work very well in terms of heating, but I would urge others to consider the spatial constraints when purchasing.

Rated 5 out of 5 by from Best heater tape on the planet I used heater tapes like the ones I recently purchased from Omega for decades in various application at work, for several scientific research and engineering companies. Now retired, I wouln't consider buying any other brand.

What is the minimum bending radius of these tapes? Unfortunately, I couldn't find any information on your website or in the technical sheets about this.

Asked by: Keivan
Thank you for your inquiry. Minimum bend radius can be no less than twice the width of the tape.

If I wrapped the reactor using this heating tape to heat from 20 C upto 120 C for 100 s, can I assume that the total energy used is 420 W * 100 s = 42 kJ?

Asked by: Kate
Omega provides the Wattage for the Heaters at the specified Voltage and any Energy calculations with a time component would be the customers responsibility.
