ESS, HALT/HASS, and other fast change rate chambers typically require the use of liquid nitrogen (LN2 ) systems instead of conventional electrical power in order to achieve the high product temperature change rates. These systems may be unfamiliar to customers and require specialized knowledge, tanks, and piping, and control systems.
In cooperation with our strategic alliance partners, we can provide you with a single source for all your test/stress chamber requirements. From start to finish we will provide you with a fully integrated test system.

Our Products
Our company is particularly pleased to offer engineering test solutions and unique and customized environmental test equipment and systems for product quality and reliability. Included are specialized environmental chambers as well as a complete line of advanced Highly Accelerated Life Test (HALT) and Highly Accelerated Stress Screening (HASS) chamber systems.
- Environmental simulation of natural and induced environments are the traditional test applications for product design evaluation and development. Simulation of product transportation, storage, and use environments typically include temperature, thermal shock, humidity, vibration, shock, salt spray, altitude to name a few. We specialize in customized environmental equipment solutions.
- Environmental stimulation of products for improved product quality and life typically utilizes temperature, vibration, and optional humidity singularly and in combination, to precipitate product latent defects.
- Environmental conditioning during manufacturing can require many unique and specialized environmental conditioning and processing chambers and equipment. We have accepted many challenges in this area and have provided a successful equipment response and solution.
IMPORTANT: Environmental stimulation has no relationship to environmental simulation of product environments. It is simply an application of environmental stress find product failures. (Read More).
Two important application areas are: Highly Accelerated Life Test (HALT) and Highly Accelerated Stress. Screening (HASS). See HALT/HASS Chamber performance specifications and models sizes (Read More).
Environmental Stress has wide applications as related to product development and manufacturing:
-
During Environmental Simulation we look for products to pass. This application typically simulate the natural, induced, environments singularly or in combination during the product development and/or qualification of products to their environmental specifications. Product development under environmental conditions is an iterative process, Test, Analyze, And Fix, (TAFF) and can take a relatively long time.
-
During Environmental Stimulation we look for weak product components to fail. Product development under environmental product stimulation is also an iterative process, Stress, Analyze, And Fix, (SAAF) and can take a relatively short time.
- During Environmental Conditioning we subject products to environmental conditioning or stress as required by the manufacturing requirements.Environmental chambers typically have different characteristics and configurations for the each application.
HALT and HASS are summarized as follows:
- HALT, by means of ever increasing environmental stress step levels determines product design limits (margin) and destruct limits. This is also an iterative process as noted above, "SAAF". The result is a robust product with extended life. HALT is also very useful in estimating product life and warranties particularly if normal levels of usage stress are known.
- HASS utilizes information from HALT to establish screening strength levels for use in production. If a HALT has not been performed the screening strength can be determined through step-stress-testing similar to that done in the HALT method. In all cases the levels of stress are tailored for each product. The objective is to precipitate weak components, workmanship problems or process problems, determine root cause and take corrective action while taking minimum life out of the product.
John Hanse founded Hanse Environmental, Inc,. in 1989. John has twenty-five-plus years experience in the environmental chamber industry. He was an early pioneer in the development of environmental stress screening (ESS) equipment.
Subsequently, ESS equipment found application for accelerated life testing and accelerated stress screening with the acronyms HALT & HASS. The initial Hanse systems were sold to Whirlpool and to Ford Motor. Since that time the worldwide demand for chamber systems has expanded, and Hanse chambers are sold to an ever-widening user base.
Product Development
Today, we manufacture the largest standard line of what we believe to be the most advanced performing HALT/HASS chambers in the industry. We have concentrated our engineering efforts to advance the state-of-the-art of HALT/HASS chamber performance.
Eight models are standard. Customized configurations are available also. Temperature cycling and six-degree-of-freedom (6DoF) vibration systems are available in eight stand-alone models
In addition, we design and manufacture specialized environmental chambers (humidity, corrosive, temperature/humidity, etc.) with extreme performance requirements.We also design and manufacture manufacturing processing equipment which requires environmental conditioning. We take pride in providing not only an equipment response, but also a solution to many challenging requirements.
Strategic Alliances
We have alliances with companies with strategic technology in the fields of vibration fixturing, instrumentation, and LN2 facilities. This is valuable resource for our customers. Through cooperation with our allied companies, we can offer a turnkey solution, a one-stop-shop.
We have also established strategic alliances with other global manufactures of environmental equipment for incorporation of Hanse 6DoF vibration systems into their chambers. (Read more).
Seminars and Training
In the early 1990s a sister company, Hanse Technology, Inc., was formed to present annual series of ESS/HALT/HASS Seminars throughout the United States. Hanse Environmental also conducts similar seminars and presentations worldwide. Our new team of experts will customize on-site seminars according to individual company needs.(Read more).

We support the concept of global strategic alliances. It can be beneficial to both parties and to our customers,as well. There are two main areas for Strategic Alliances:
Strategic Technology
We have alliances with companies with strategic technology in the fields of vibration fixturing, instrumentation, and LN2 facilities. This is a very valuable resource for our customers. Through cooperation with our allied companies, we can offer a turnkey solution....a one-stop-shop.
OEM and Licensing
Our proven history of advanced technology and reliability of our HALT/HASS chambers has resulted in requests from manufacturers to provide vibration systems on an OEM basis. They have also requested to license our chambers for manufacture . In response to this demand, we are pleased to offer two programs: OEM and Licensing.
-
OEM
-
In our OEM program, we will supply our proprietary 6DoF vibration table and controls as a complete subassembly to other environmental chamber manufacturers for incorporation into their own HALT/HASS chambers. EMIC Corporation, Japan, is one of our strategic allies.
-
Licensing
For those companies that wish to manufacture HALT/HASS chambers, but have not done so before, we are prepared to license our proprietary chamber designs and also license their manufacture under strict configuration control. The 6DoF vibration table and controls are not included in the license. They will be supplied as a complete subassembly, just as we do for our OEM partners.
