Gem three-door reach-in freezer - how many HP?

[Poodle Head Mikey]

Someone stole the condensing unit for this Gem three-door freezer. Three 30" doors. What HP condensing unit would you think it requires? The owner claims there is no model number on it.

wild ass guess would be 1 HP. I'll look at some old books when i get to work.

I agree with 1 HP if it has solid doors. Glass doors would require a 1 1/2 HP like a KATB-015E-CAV.

I forgot the doors - they are glass: display doors.

Good thing I asked you - the owner said that he thought it had been 3 HP - which seems high to me - but I was still guessing 2 HP. <g>

But 1 1/2 HP will do it huh?

I was going by memory and what is currently used in 3-door reach-ins.

I do recall working with a 3-door Pinnacle however, which had a 2 HP EAV2-0200.

say you oversized it by 1/2 hp , what might that do ....

As long as the TXV (or the cap tube) is properly sized for the condensing unit capacity there should be no problem going up one size. It'll run a slightly lower evap temp and be able to hold a lower box temp. Supermarket cases do this all the time with essentially the same case for either frozen foods or ice cream. the ice cream just requires a bigger unit to hold the lower temps.

Actually, in PHM's case, the 2 HP unit may be the prudent approach. I found some old literature for a couple of other 3-door display freezers which called for 2 HP units.
