DETERMINE POWER PACK SIZE
USE BTUs INSTEAD OF LENGTH OF RUN
Select the most e昀케cient power pack for a beer system by calculating its total BTU (British Thermal
Unit) load. Each power pack’s BTU capacity is a numerical expression of the heat it can remove
from a beer system as it circulates glycol. Each beer system has a unique BTU load that it exerts
on the power pack chilling the glycol. If the exerted BTU load exceeds 60% of a power pack’s BTU
capacity, the compressor in the unit will need to run longer to maintain the glycol bath temperature.
This will overwork the power pack compressor, and ultimately shorten its life. The goal is to have long
compressor run times and equal rest times (or as equal as possible). Determining the right power pack
to handle a beer system capacity is accomplished with a simple formula.

NEW DIGITAL
BTU CALCULATOR
Calculate using 100 BTUs per faucet, and trunkline BTU's per foot. Add these totals together and
multiply by 1.4 to 昀椀nd the total BTU capacity required.
