Thermal & Process Equipment
WHERE THERMAL FAILURE IS NOT AN OPTION
Thermal and process equipment operates at the intersection of precision and extreme heat — where maintaining exact temperatures across heat exchangers, reactor vessels, storage tanks, and dryers is critical to process integrity, product quality, and operational safety. McAllister Mills designs and fabricates custom insulation and thermal protection solutions engineered to maintain precise thermal control across the full range of process equipment configurations.
COMMON CHALLENGES
Precise temperature maintenance across complex equipment geometries
Heat loss reduction for process efficiency and energy savings
Personnel protection from high-temperature vessel and piping surfaces
Insulation solutions that accommodate thermal expansion and contraction
Maintenance access without full insulation removal or replacement
- Compliance with process safety and environmental requirements
Featured Applications

Heat Exchangers
Thermal insulation solutions for heat exchanger shells, heads, and connecting piping designed to minimize heat loss, maintain process temperatures, and protect personnel from high-temperature surface contact. McAllister fabricates removable insulation jackets custom-fit to heat exchanger geometry, allowing maintenance teams to access tube bundles and internal components without damaging or discarding insulation.

Reactor Vessels
Custom insulation jackets and thermal protection systems for reactor vessels, agitators, and associated piping where precise temperature control is critical to process integrity and product quality. McAllister solutions are engineered to maintain consistent thermal performance across the full vessel surface while accommodating nozzles, manways, and other access points that require regular opening during operation and maintenance.

Storage Tanks
Insulation systems for storage tanks holding temperature-sensitive materials, process fluids, and chemical intermediates requiring consistent thermal conditions during storage. McAllister fabricates tank insulation solutions that minimize heat gain or loss, protect tank surfaces from thermal stress, and provide durable long-term performance in indoor and outdoor environments.

Dryers
High-temperature insulation solutions for industrial dryers, ovens, and thermal processing equipment where heat retention directly impacts process efficiency and product throughput. McAllister designs and fabricates insulation jackets and panels engineered to fit dryer housings, doors, and access panels while maintaining consistent internal temperatures and reducing energy consumption across continuous operation cycles.
