Deltech Kiln and Furnace Design, LLC (aka DKFD, LLC) was founded in 2016 to supply electric laboratory furnaces and related supplies and equipment to the nuclear science, engineering, and technology communities. The decision to form DKFD was made after Deltech, Inc. was approached by Merrick & Company here in Denver, Colorado to act as a subcontractor for the supply of furnaces to a nuclear facility. Designs, processes, and products must meet rigorous nuclear quality assurance requirements, and DKFD is positioned to design and subcontract the most complex custom furnace systems, providing quality assurance oversight and documentation at every step in the design, build, test, delivery, commissioning, and maintenance processes.

DKFD qualifies as a small business concern
