Electric Box Furnace - AMS2750E Class 3 For Aircraft Landing Gear Structures

L&L Special Furnace has commissioned a large resistance box furnace and quench tank in New Zealand for a leading aerospace manufacturer of landing gear and associated components.

The company has supplied a model XLA3472 with an effective work zone of 22” high by 34” wide by 68” deep. The oil quench tank provided with the furnace is capable of quenching parts up to 24” by 36” in oil.

The furnace is equipped with a pyrometry package for AMS2750E class 3 equipment with temperature uniformity of ±15°F throughout the operating range. It includes a survey port, thermocouple reference ports and corner locations to record the high and low temperature points inside the furnace as indicated by the most recent survey.

The model XLA3472 has a single control loop. The heating circuit is divided into six individual element banks with SCR power controllers and potentiometers to balance temperature gradients throughout the furnace. The control is a Eurotherm / Nanodac temperature controller/paperless recorder. Also included is a separate overtemperature protection controller and a separate paperless chart recorder with dedicated TUS software.

L&L is adept at offering furnaces equipped with pyrometry packages to meet AMS2750 and soon-to-be-certified MedAccred guidelines. A three-day, all-inclusive startup service is included with each system within the continental US and Canada. International startup and training service is available by factory quote.

If precise temperature control and uniformity is key to your process, then L&L’s XLE series is a great choice. Please be sure to visit our new website at www.llfurnace.com.
