Lucifer Furnaces Delivers Custom AMS2750-Compliant Furnaces for U.S. Space Company

Lucifer Furnaces is proud to announce the successful delivery of a custom-built, AMS2750-compliant general-purpose box furnace for a well-known U.S.-based space company supporting advanced aerospace and spaceflight programs.

Designed to meet the stringent requirements of aerospace heat treating, this furnace reflects Lucifer Furnaces’ long-standing commitment to precision, reliability, and robust thermal system design for mission-critical applications.

Built for Aerospace Performance and Compliance

The furnace, a Lucifer 5000 Series Heavy Duty Industrial Furnace, was engineered specifically to support high-temperature processing while maintaining strict temperature uniformity and control—key requirements for aerospace and space manufacturing.

Key specifications include:

• Model: HL5-V60-AMS2750

• AMS2750 Compliant: Class 3

• Temperature Rating: 2300°F

• Chamber Dimensions: 36" H × 36" W × 60" D

• Automated forced cooling system

• Roller rail assembly with external charge cart 

This configuration provides ample working volume while ensuring repeatable, tightly controlled thermal performance suitable for critical aerospace alloys and components.

Integrated Forced Cooling System for Faster Cycle Times

Following the initial purchase order, the customer expanded the system to include a forced cooling package on both furnaces ordered, further enhancing productivity and operational flexibility.

The forced cooling system was engineered to significantly reduce cooling times while maintaining control and safety. Key features include:

• Blower-assisted exhaust system mounted through the roof of the chamber

• Motor-actuated, insulated exhaust damper housing

• Makeup air inlet through the lower rear wall with insulated damper

The system can be:

• Activated manually via a push button on the control panel

• Engaged automatically through a programmable controller relay

This design allows heating and cooling cycles to be seamlessly integrated, helping the customer improve throughput without compromising temperature control or furnace longevity.

Engineered for Stability, Longevity, and Uptime

A key driver for this project was long-term process stability. The furnace’s robust mechanical design and thermal architecture were developed to stay within AMS2750 tolerances for years, reducing downtime, minimizing recalibration events, and supporting consistent compliance over the life of the equipment.

This focus on durable, stable furnace construction is especially critical for aerospace and space applications, where repeatability, traceability, and reliability directly impact program success.

Supporting the Future of Space Manufacturing

Lucifer Furnaces has been building heat treating furnaces to meet demanding aerospace specifications for over 75 years. This project represents another example of how custom furnace design—paired with deep application knowledge—helps customers meet evolving performance, compliance, and production goals.

As space and aerospace manufacturing continue to advance, Lucifer Furnaces remains committed to delivering thermal processing equipment that supports innovation while meeting the highest industry standards.
