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

    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.

    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.

    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.
