Graham Corporation
Founded in 1936Headquartered in Batavia, NYManufacturing in Batavia Financially strong, growth drivenTrading as GrahamCp on the American Stock Exchange400 employees
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
