Humidification chambers

We are looking to replace our walk-in humidification chamber for use
in the treatment of organic materials.  I am hoping to hear from
others who already have such a piece of equipment, whether it be a
large, walk-in humidification chamber or a room dedicated to
humidity treatments.

The intention is to have a cabinet with controllable temperature and
humidity, with the humidity being adjustable from ambient (or below)
to around 90% RH. I am envisaging a cabinet of at least the
following dimensions: width 2400mm, depth 2400mm, height 2450mm

In the UK, I have seen one such cabinet converted from a walk-in
freezer for the pharmaceutical industry to give tight RH control,
and know of a plan in progress to convert a room for humidity
treatments as an alternative to an RH chamber.  I will be
investigating both of these options further.

As this will be a major expense, I would welcome any help or advice,
so I can learn from others experience.  What things do you like, or
not like, about your cabinet?  Are there improvements you would
suggest if you were replacing your cabinet?  Can you suggest any
suppliers?
