Don and Dan
Don, I will send my contact info shortly.Dan, Gary has a good point regarding the fancoil unit. They are easy to install as are most dc conversion kits and would, by design, offer a rapid temperature pull down. Just bear in mind that this is an off cycle defrost system, which means the evaporator temperature is, by virtue of the thermostat, brought to a high enough temperature that can cause the box temperature to rise to an unacceptable temperature if not monitered properly. I would suggest that you be certain that the evap. temps will be stable with such a unit.The term "off cycle defrost" is virtually non-existant these days. In the commercial refrigeration world, this evaporator defrost cycle is accomplished with defrost heaters, defrost termination thermostats, hot gas defrost, etc. This is not practical with a dc system, hence the off cycle defrost. There is some excellent educational info regarding this subject out there and i would urge anyone considering this style of evaporator to do their homework before being subject to what may possibly be unsatisfactory and unhealthy refrigeration temps.
