For more than 100 years and four generations, J.J. Crewe & Son, Inc. has engineered and fabricated gas compression and industrial refrigeration systems from its Maryland-area operation. The OEM shop builds packaged equipment for compressor manufacturers including Sullair, Aerzen, Howden and Knox Western, while also providing service and engineering support for its own and other manufacturers’ equipment. Its process-engineering background lets Crewe jointly specify, shop-fabricate and test skid-mounted systems before delivery.
