Vacuum systems (GRAHAM)
Description

Graham Corporation is a world reference in vacuum and heat transfer technologies, with a track record dating back to 1936 and a very consolidated reputation in refining, petrochemical and energy. The company is distinguished by its applied engineering approach, its accumulated experience in ejectors, condensers and special heat exchangers, and its ability to resolve highly demanding thermal and vacuum services.

In vacuum systems, Graham develops custom solutions based on steam jet ejectors, liquid ring vacuum pump packages and hybrid configurations. Steam ejectors remain one of its major differentiators due to their moving-parts-free design, their robustness in severe environments and the brand’s specific experience in steam consumption and internal geometries.

The company complements these items with process condensers and other auxiliaries to deliver a single, optimised system, particularly valued in vacuum distillation, degassing and other critical operations.

These solutions are aimed at refining, petrochemical, power generation, edible oils, chemical and other industries where vacuum or condensation form an essential part of the process.

Graham provides an uncommon combination of vacuum and heat exchange knowledge, very valuable when system design weighs as much as the individual piece of equipment.
