We have the Peko drying cabinets too, a combination of the older ETS-650 and the current ETS-1900TR models. They're brilliant on wet days but they do need to be vented to the outside or an otherwise well ventilated area. At my work we converted some old toilets to changing rooms and were able to run the cabinet hoses to atmosphere.
Peko says:
"Is the cabinet available with condenser / heat pump technology drying?
Yes. The Podab TS 63 VP is an energy efficient cabinet using heat pump technology. Other models are currently undergoing field trials. It is hoped that these will be available in the UK sometime during 2014. Existing cabinets can be operated in conjunction with a separate condenser box to prevent the build up moisture in the room. The condenser box is available from independent suppliers."
It's worth noting that if you have a condenser, either you need to plumb it into a drain or have someone contracted or volunteering to empty it periodically.
I wouldn't get too hung up on sub-1 hour drying times, as most people seem to allow themselves at least half a day.
On the back of what Snowy suggested, you might alternatively look at wire mesh lockers with integral solid dividers:

and these will let stuff air-dry by itself.
