Environmental Chambers and Space Simulation Systems

The Bemco Story

A California Corporation founded in 1951 by a WWII combat P38 Lockheed Lightning pilot who served in Europe.

Bemco is the oldest environmental test equipment company under continuous ownership in the United States. If you include our Conrad/Missimer Division, this is our 75th year.

In 1958, Bemco made the first orbital space simulator in the United States. Many Bemco systems made in the 50's, 60' and 70's are still functioning reliably today.

In 1972, Bemco purchased Conrad/Missimer, the then industry leading manufacturer of environmental test chambers from Gulf and Western (now Viacom). Many of the unique products Bemco offers today, such as the Universal Test Machine, FTU and the Compact Temperature Chamber, FB1.5, came with this purchase.

Almost every US space program has in some part been tested in a Bemco Space Simulator, Bemcoil Thermal Shroud, or a Bemco manufactured Thermal Vacuum System.

Bemco products can be found in laboratories and test facilities all over the world in almost every industry including aerospace, defense, electronics, automobile, medical, and consumer products.

Today, Bemco continues to develop new products and skills. With the most experienced engineering and production staff in the industry, we are proud of the quality equipment we make.

Environmental Test and Space Simulation

Bemco FW30 Glass Front Humidity Chamber with Optional Recorder You have probably already noticed that we offer a more diverse product line than any other US manufacturer.  It is no secret why. We are celebrating our 55th year in continuous business!

In many areas we are the absolute market leader in both volume and quantity.  We are the number one manufacturer of factory assembled Space Simulators and Thermal Vacuum Systems.  We are also the highest volume worldwide vendor in high pressure liquid nitrogen cooled gas circulation systems and both mechanically and liquid nitrogen cooled aerospace grade Fluid and PAO (polyalphaolefin) chillers.

We manufacture many unique products available only from Bemco.  Examples include our FW30 Glass Door Temperature Humidity chambers, our TS Rotary Thermal Shock chambers and our Bemcoil stainless steel thermal shrouds. In other cases our products are simply the best.  They are so carefully conceived and executed that many competitors copy our efforts.  Examples of these systems include the Bemco F, FNR and FHC temperature chambers, the A, AF and AFW altitude chambers, the FB1.5V and the FTU universal test machine chamber, originally conceived by our Conrad/Missimer Division in the 1960's.

The Kardburn - Koldburn glass door burn-in and temperature cycling chambers and the FS Series of three zone thermal shock chambers are original Bemco inventions. We make everything from the compact to the absolutely huge.
