Chamberland Engineering Associates and Sentry Equipment Corporation Partners in Excellence!

Chamberland Engineering Associates is proud to continue our relationship with Sentry Equipment Corporation.

If you need a sample cooler or sampling equipment for steam/water, gases, liquids, slurries or bulk solids, you have come to the right place. Sentry has over 80 years experience in manufacturing sampling components and sampling systems. We also manufacture compact heat exchangers and boiler blowdown heat recovery systems.

History of Sentry Equipment Corp

Sentry began in 1924 as The Henszey Company, a primary supplier to The Carnation Company for dairy power plant components and milk evaporators. In 1959, we changed our name to Sentry Equipment Corp and refocused efforts toward the power generation industry for sampling products and specialty heat exchangers. This effort not only expanded to other industries, but also into the supply of complete systems for power plant steam and water monitoring.

Sentry is an innovative company responsible for many firsts including compact helical coil sample coolers, adjustable ultra high pressure reducers, radiation-shielded sampling stations, and non-coring needle samplers.

1986 - Employee ownership
Company ownership was transferred to the employees through an ESOP (Employee Stock Ownership Plan). Today, Sentry is 100% employee-owned. The employee owners of Sentry participate in making improvements to our products and processes at every level. This is emphasized in our corporate vision statement: Every Employee and Owner, Every Customer a Commitment.

2002 - Acquired the Dual Heat Transfer Coil
Sentry acquired the product line from Parker–Hannifin Corp. This tube-in-tube heat exchanger expanded Sentry’s offerings of specialty heat exchangers – Sentry now offers sample coolers, spiral tube, custom helical coil and tube-in-tube heat exchangers.

2003 - Acquired Bristol Equipment Company /ISOLOK®
Bristol has a well-respected reputation in the industry for providing unique solutions for the sampling of liquids, slurries and powders/pellets with the ISOLOK® automatic sampler.

2005 - Acquired Gustafson Automatic Samplers
Sentry acquired the product line from Bayer CropScience. The Gustafson sampler line provides sampling solutions for a variety of bulk solids including granules, flakes, powders, pellets and slurries, and serves a range of industries including cement, chemical, plastic, coal, feed/grain, food, dairy and fertilizer. This addition to Sentry’s existing line of manual and automatic samplers for gases, liquids, slurries and bulk solids created the most comprehensive line of products for process sampling applications in the world.

2007 - Built new headquarters building
Due to the above acquisitions and organic business growth, Sentry was bursting at the seams in its previous location. A new site and new building were designed to fit Sentry's needs and in August of 2007 the entire company was relocated to the 51,100-square-foot building just 3.5 miles away.
