Desiccant Dehumidification - Manufacurers
Desiccant Dehumidification - Manufacurers
(OP)
Does anyone have recommendations on a good quality manufacturer of desiccant dehumidifiers and at the same time "mfgs" to avoid. I'm designing an ice rink with RQRMNTS at 55 F @ 40% RH and desiccant is the way to get that low moisture requirement. I would hate to spec a crappy system!!!
ASHRAE Ventilation is a killer on ice rinks - 0.5 cfm per SF of ice - which must be because of gas operated ice making resurfacing machines. I see no exception of avoiding this high OA vetilation rate. Any comments on this also???

Why 40% RH requirement? Very low humidity can be problematic in athletic facilities, as it can lead to dry throats.
Why have you ruled out cooling the air below dew point as a means of dehumidifcation?
On the ventilation thing, could you bump up the ventilation only when the Zamboni is running? You could interlock this with a radio frequency gizzmo.

The reason for the low RH and dew point is condensation issues & fog issues. Certainly will use cooling to treat air from HOT Summer Conditions to reasonable levels. However, ice rinks seem to be the one acceptable application for desiccant usage.

These "Big Boys" will tell me not to go desiccant as the argument of "over cooling" versus absorbtion goes on. This application (an ice rink) doesn't need the internal cooling - the heat gain is not there! The sensible cooling requirements are minimal - The latent heat removal is a killer.
I just want to make sure I have a quality and reputable manufacturer like these big boys and their DX cooling units!

Go to (www.zamboni.com) and you'll see electric powered machines (Model 552). Maybe you need to respec the zamboni.
Just a thought
