Home Accessories Dew Control Systems Dew Zapper Heater Tapes DewZapper 7-8" OD Dew Heater Tape 87cm Long
DewZapper dew heaters are the high quality solution, with a geniune Nichrome wire heating element embedded in a silicon rubber subtrate, for durability and moisture-resistance. The 22 awg silicon coated wires have a synthetic rubber outer sheath, which remains flexible even in very low temperatures reducing "cable pull" related tracking errors. The RCA power jacks are bonded with flexible glue and a heatshrink tube for strain relief. A high quality Velcro pad sewn onto an elasticated strap is included for easy fitment. An internal neoprene insulator directs heat into the optics so you won't waste any power. High-quality Male RCA plug fits most Dew Controllers with a 12v output (never exceed 12v).
There is simply no comparison with heaters which use thin audio cables and thin-film or "foil" heating elements, which are crimped to the wires, creating a failure point. DewZapper dew heater technical specs: Fits Celestron Nexstar 8, CPC 8, Meade LX series 8" SCT, Skywatcher 180 Maksutov or any telescope with 7-9" outer tube tube dia. Total Length 870mm, width 40mm.Stops condensation, moisture, fogging on telescope lenses or large telephoto lenses. Efficient with low power consumption. (Power consumption & heat output are determined by 12v controller power setting). High quality silicon cable with rubber outer sheath, glued to RCA jack for strain relief, remaining flexible at below zero temperatures, and moisture resistant. Includes neoprene insulator on the back of the heater to direct heat inwards to the optics for better efficiency. High-quality long lasting Nichrome wire heating element embedded in a fused flexible silicon substrate for moisture resistance and reliability. (NO "thin-film resistors" or "foil elements" are used!) Produces max 20 Watts, 1.7A at 12v 100% duty cycle. High-quality Male RCA plug fits most Dew Controllers with a 12v output (never exceed 12v).
Good quality tapes and excellent service Very prompt delivery. I have a number of these tapes in varying sizes, they are well made and do just what it says on the tin. The cables are sturdy and remain flexible at low temperatures. This particular size is a good fit for my RASA 8. (20/12/2020) - Mid Wales
Effective heater Completely solved the fogging problem on my Meade LX. Easy to set up and appears well made. The telephone advice from Harrison Telescopes was very useful with regard to the Heater Tape and the Pegasus V2 Controller and saved me from buying extra unnecessary kit. (12/03/2019) -
I have had bad experience with past due heater straps that have frustratingly left horrible visible black marks on my white TMB optical tubes. I had an absolute nightmare cleaning these marks off. However, Ed of Harrison telescope knowing my past problems, introduced me to The Dew Zapper Heater Tapes. Well, all I can say is, what a top quality product. Thank Ed! These Heater Tapes are well made, and have a generous length of moisture resistant leads that I’m please to say is massively beneficial for long focal telescopes. Also no more horrible black marks on my telescope tubes this for me just say quality. On a final note I’m please to say my new Dew Zapper Heater Tapes are now in full use connected up to my two Pegasus dew systems. (09/11/2018) James Howes - South East London
