Graham Corporation

Design & manufacture vacuum & heat transfer equipmentSeventy years of historyOver thirty engineers on staff with an average of 15 years experience specializing in these fieldsLeader in organizations like HTRI,TEMA and API

Coiled Tube Technology

In 1935 Graham invented the coiled tube technology for transferring heat from one fluid to another.

Coiled Tube Bundle

Most compact heat transfer surface utilizing tubesSpiral affect increases heat transfer rateDifferential thermal expansion is okayHeliflow brand heat exchangers

Standard Plant Steam

Contains trace amounts of boiler feed chemicalsSulfites of hydrazine for Oxygen removalAnti-scaling compoundsCorrosion control chemicals

Clean Steam

Filtered – Plant steam filtered at 5 microns. May contain boiler chemicals.Clean Steam – No boiler chemicals used. Often uses deionized or distilled feed waterPure steam – Produced from deionized or distilled, pharmaceutical quality water

Applications

Equipment sterilizationClean in place systemsAutoclavesDirect injection heatingEquipment wash down stationsHumidification

Clean Steam Generator

Graham Advantage

Hot side & cold side independently optimizedBoiling side velocities are optimized by adjusting the coil spacingPressure drops minimized by increasing the coil spacing

Graham Advantage

A reduced possibility of leakage due to the minimum number of jointsThermal expansion and shock problems eliminated due to the spring like coil.A proven track record over 60 years of service
