About this file

This document is an engineering drawing and proposal for an industrial oven manufactured by The Grieve Corporation for the U.S. Army RDE - ARDEC Benet Labs. The drawing depicts a Modified LA-1050 model laboratory oven with detailed specifications and dimensional information for manufacturing and approval purposes.

The oven features a workspace of 36" wide by 36" deep by 45" high with a maximum operating temperature of 1050°F and 60 kW total heat input. Key components include a 5 HP blower rated at 6000 CFM, a 975 CFM belt-driven carbon steel exhauster, 10" wall insulation throughout, horizontal air flow from left to right, modulating dampers on fresh air and exhaust, and a 1000 LB floor capacity with reinforced carbon steel subway grate. The unit operates on 480V/3/60 electrical service with NEMA 12 electrical construction, features an automatic door switch, and includes certified and calibrated Type J thermocouples. The interior utilizes aluminized steel with 304 stainless steel heat chamber, while the exterior is aluminized steel painted Trilite Green machinery enamel. Additional features include an elapsed timer, GFCI receptacle, USB port, circular chart temperature recorder, and an additional 1/2" NPT stainless steel pipe port for customer monitoring. The drawing requires approval with signature blocks for three reviewers and notes that air supply requires 60 PSIG clean compressed air. Purchase order number W911PT2590057 is referenced, with the drawing dated 8/4/2025 and shop order dated 8/6/2025.
