Products & Services
Industrial Gases
Industrial gases are pure elements, molecular compounds or mixtures that are gaseous or vaporous at room temperature and pressure.
Cooling Towers
Cooling towers are defined as any open water recirculation device that uses fans or natural draft to draw or force air to contact and cool water by evaporation.
ISO Containers
ISO containers, also called intermodal containers, are designed to transport freight by ship, truck or rail.
Chemical Process and Petrochemical Gases

Chemical process and petrochemical gases are materials used in the production of compounds or products. They are used in processes such as inerting, blanketing, purging, sparging, and stripping. These gases are used in many applications including treatment and sterilization, medicine, energy solutions, and manufacturing.

Fluid Heat Transfer Systems
Fluid heat transfer systems circulate thermal fluid through process equipment to maintain an even, consistent temperature profile.
