Steam Testing Chambers

Useful for steam oxidation, testing steam reactions in the laboratory, testing for environmental innovation, and food or  antimicrobial testing purposes

The chambers may be used for steam up from low-temperature 1300C depending on the model.   Independent control of steam, gas, and chamber with industry-tested control panels.

There are two standard models.  Contact for standard models to 300°C and 1300°C for testing for example bacterial inactivation in food or for testing for long times in fresh steam conditions.

Accurate sample positioning and multiple temperature readouts are offered.

Please contact MHI for details to specify the steam flow rate and temperature and the sample size and temperature.

These are one of the best test chambers as they allow for continuous-flowing clean steam to provide steady-state test conditions with time-independent steam gas.

The smallest chamber size available is 1″ID and a 4″ Long, open chamber.

FAQs for Steam Chambers

(Based on questions from previous sales).

(a) Are there recommended minimum & maximum coupon sizes for superheated sample testing? The chamber is 1.5-inch in diameter & 4-inch in length.

(b) Can gas be introduced.


(c) What is the incremental distance (upper and lower) between the coupon and the steam applicator? Can I vary the steam rate? Yes with a CN-BPE or BPE.  The CN-BPE if offered for the model is an   Infinite type Adjustment.

(d) Are there any constraints in varying coupon exposure time to superheated steam? (e.g. minimum exposure time & max exposure time)?


(e) Are the coupon (or) steam applicators, both are fixed? In other words, if we need to vary the sweeping rate, can this be done? (it may be related to question c).

Sample Holder is Multi-axis # Tilt Positions

Fixed or you can continuously change.

(f) presume we can monitor humidity within the chamber with an appropriate probe sensor during the experiments

Please see   Humidity is not defined for high-temperature steam

(g) What are the upper and lower limits of temperature for steam that can be used during the experiment? at what increment temperature can be controlled?

Up to ~400C or 1000C or 1300C.  Infinite control is allowed by MHI control systems.

(h) can the steam velocity be varied?

Not without changing nozzles.  A ¼” nozzle is provided.  Note that the volume flow rate is fixed.

(i) Are there any constraints with a water source (e.g., DI water or tap water is OK?)

RO water is preferred.

(j) Do you offer a Data Acquisition system?

The models are supplied with an interface for data acquisition.

(k)  What if I want a moving product steam tunnel

Please link to steam tunnels.
