DESIGN LOGIC ENGINE PREHEATERS
 

(Click image for a larger view)
Constructed of solid aluminum, Design Logic Inc.(formerly Symtec Inc.) preheaters are known for their dependability, performance, and overall value since 1994. Heats entire engine (Lycoming O360-A4K: Oil 120° F., CHT 62° F. @ 20° F. OAT). Robust design saves time & money by allowing easy transfer to other engines or reinstallation after overhaul.

Why Design Logic Pre-heaters? Design Logic Aircraft Engine Pre-heaters are famous for their durability and reliability:
  • Heats entire engine
  • Use an extruded aluminum construction that is durable but also lightweight (13 oz). The size of the unit is either 5 x 4-5/16” or 5 x 2-3/4” (depending on model). Models can be used for over 600 Lycoming and most Continental engines as well as some Franklin, Garrett, and Marathon.
  • The pre-heater is impervious to puncture and contaminants.
  • Can be reinstalled after overhaul or to another engine.
  • Can be left on continuously (the heater is thermostatically controlled: 170- 200 deg. F.).
  • The heater will never overheat. A thermal fuse shuts off the heater should the heater ever become dislodged from the sump and the thermostat fail.
  • Can be used with portable generators.
  • 220 watts; two, 110- watt heater cartridges in parallel.
  • Extremely simple installation. Installs with a 2-part epoxy (included) that is heat cured when unit is plugged in.
Cessna Owner Magazine described the easy installation of the Design Logic Pre-heater, “All (the installation) went precisely as the instructions said that it would with no skinned knuckles and no cussin’. It was just perfect… Installation is a straight-forward adhesive application, with no surprises.”
  • Minimal paper work. Installation is considered a minor modification with no STC or 337 entry needed. Simply make a log book entry.
  • FAA/PMA approved.
  • Two-year, unconditional guarantee; the best in the industry
