Every Employee An Owner,Every Customer A Commitment....

Spiral Tube Heat ExchangersSentry spiral tube heat exchangers consist of two manifolds joined by avariable number of parallel tubes based on duty requirements. The assemblyis then coiled into a spiral or scroll. When the tube bundle is inserted into theshell, two fluid paths are created for full counter flow heat transfer.

Up to 40% more efficient than a Shell & TubePressure ratings exceeding 10,000 psi (690 bar)Compact and lightweightHighly resistant to thermal and pulsation shockLeast expensive construction for exotic materialsHeat transfer areas up to 150 ft2 (14 m2)Optional ASME "U" stamp

Bulletin 12.1.1

Helical Coil Heat ExchangersSentry makes a variety of single tube helically wound (single and double)compact heat exchangers for a broad pressure and application range with orwithout shells. These heat exchangers are well suited for OEM applicationsincluding oil coolers, sump coolers, sample coolers and other high pressure,high temperature, low flow applications.

Pressure ratings exceeding 10,000 psi (690 bar)Compact and lightweightHighly resistant to thermal and pulsation shockStandard 316SS construction with other exotic materials availableHeating transfer areas up to 5 ft2 (0.46 m2)Optional ASME "U" stamp

For All Types of Process Heating and Cooling

Boiler Blowdown Heat Recovery SystemsThe unique Sentry proportional control system iswidely used throughout the world for boilersoperating at pressures below 250 psi (17 bar), andSentry offers the only system available for lowpressure (15 psi / 1 bar) heating boilers. Sentryalso offers flash tank/heat exchanger systems forboiler pressure up to 900 psi (52 bar). Sentry is theonly supplier to offer all three types of blowdownheat recovery systems.Bulletin 3.1.8

Specialty Heat Exchangers

SENTRY – Over 75 years of experience!Sentry is a worldwide supplier and technology leader in sampling components/systems and specialtyheat exchangers. We supply our products and services to most process industries including powergeneration, hydrocarbon processing, chemical, and pharmaceutical as well as the OEM manufacturersthat serve these industries. Our products provide our customers with simple and efficient ways toimprove performance, reduce maintenance, and expand capabilities.

Engineering excellence is the thread that runs through our history since our beginning in 1924 as TheHenszey Company. We began as a primary supplier to The Carnation Company for dairy power plantcomponents and milk evaporators. In 1959, we changed our name to Sentry Equipment Corp. andrefocused our efforts toward the power generation industry for sampling products and specialty heatexchangers. This effort not only expanded to other industries, but also into the supply of completesystems for power plant steam and water monitoring. We are a company of many firsts includingcompact helical coil sample coolers, adjustable ultra high pressure reducers, radiation shielded samplingstations, and non-coring needle samplers.

In 1986, the company ownership was transferred to the employees through an ESOP, and we are proudto be a 100% employee-owned company today. The employee owners of Sentry participate in makingimprovements to our products and processes at every level. We believe that value as defined by thecustomer will determine our future success. This is emphasized in our corporate vision statement.
